# Hyundai Elantra 2021–2026 · Maintenance schedule & cost to maintain

CarCaseFile editorial · filed 08-02-2026 · updated 09-17-2026

Scheduled service only, not the documented problems (those are on the [case file's problem list](https://carcasefile.com/vehicles/hyundai-elantra-2021-2026/#own), with their own cost calculator). Every interval and cost range below is sourced, not estimated.

Where the manufacturer publishes separate normal and severe-condition schedules, this ledger defaults to the **severe** interval and says so. That's not us padding the numbers: a manufacturer's own severe-duty list usually describes ordinary driving, things like short trips, stop-and-go traffic, extended idling, dust or road salt. But the list is written per manufacturer and sometimes per model year, and some are far narrower than others, so each item's "why" text names what *this* manufacturer actually wrote and gives the normal-schedule number alongside it. Read the item, not this paragraph.

Cumulative cost

## What routine maintenance adds up to, by mileage

Running total of the independent-shop cost ranges below. Each bar is everything due by that point, added to everything before it.

Solid bar = low estimate, tint = high estimate. This is a routine-maintenance floor, not a total cost of ownership. Fuel, insurance, tires, and any of the documented problems above are separate. Items that recur more than once per interval under a severe-duty schedule (an air filter due every 5k, say) are counted here at one occurrence, not the full repeat total. The real cumulative spend for a high-mileage severe-duty driver runs higher than this chart shows.

## Every 3,000–8,000 mi (oil service)

### Engine oil and filter (severe-schedule default; four powertrains, four different numbers)

$70–$145 DIY-realistic

Hyundai's severe interval is 5,000 mi/6 months on the 2.0 MPI and the 1.6 T-GDI, 3,750 mi on the Hybrid, and 3,000 mi on the Elantra N. Normal is 8,000 mi (6,000 on the N; 7,500 on the 2022 Hybrid, which moved to 8,000 for 2023 while leaving its starter-generator belt on a 7,500 inspection). Everything takes 0W-20 except the N, which takes 0W-30. Capacities run 4.02 to 5.49 quarts.

On this generation

- Every CN7 ends up on the severe schedule, and Hyundai says so in print. The 2025 book's line is "After 10 years or 100,000 mi., use severe maintenance schedule." The 2021 book says the same thing more softly: "After 10 years or 100,000 miles, we recommend to use severe maintenance schedule." A 2021 car crosses that in 2031 no matter how gently it was driven, so a high-mile CN7 is a 5,000-mile car, not an 8,000-mile one.
- The oil requirement tightened at the 2024 facelift. The 2021 book's footnote reads "Requires API SN PLUS (or above) grade engine oil." The 2024 and 2025 books read "Requires <API SN PLUS (or above) Full synthetic> grade engine oil." and go on to say a mineral oil including semi-synthetic drops you onto the severe interval. On a 2024-or-later car, a cheap blend costs you half your interval by the book's own rule.
- The Elantra N is the one shops get wrong. Its book specifies 0W-30, not the 0W-20 every other CN7 uses, 5.49 US quarts, and a severe interval of "Every 3,000 miles (5,000 km) or 6 months" against a 6,000-mile normal. Hand an N to a shop that assumes the volume car's spec and it leaves a quart low on the wrong grade.
- The turbo's severe triggers shrank at the facelift, and that is worth knowing before you authorize a 5,000-mile schedule on an N Line. In the 2022 book the 1.6 T-GDI hits the severe oil interval under all twelve conditions A through L, exactly like the 2.0. In the 2025 book the T-GDI row lists only D, H, I and L (salt or very cold weather, towing or roof loads, commercial use, wrong oil). Short trips and stop-and-go still put a 2.0 on the severe clock; on a 2024-or-later N Line they no longer do.
- The Hybrid book carries a check the gas book does not: "Check the engine oil level and leak every 500 km (350 miles) or before starting a long trip." It is printed as footnote *1 on the schedule page itself, not buried in the maintenance chapter, and 350 miles is roughly a fortnight of normal commuting.
- Every number on this page was read off Hyundai's own owner's manuals, gas 2021 through 2025, Hybrid and N 2022 through 2025. The 2026 books were not obtainable, so a 2026 owner should open their own book and check before trusting any figure here. Numbers on this generation genuinely do move: the coolant repeat, the Hybrid's whole mileage grid, the turbo's plug interval and the dual-clutch schedules all changed at least once between 2021 and 2025.

## 12,000–16,000 mi

### Cabin air filter (no severe mileage is published, so this is the normal number)

$20–$50 DIY-realistic

Hyundai replaces this every 16,000 miles on the 2.0, the N Line and the Hybrid across the whole generation. The Elantra N is the exception: 16,000 miles in the 2022 and 2023 N books, tightened to every 12,000 in the 2025 N book, with an inspection at the intervening 6,000-mile stops. The severe table does carry the row, under conditions C, E and G (rough, dusty, unpaved or salt-spread roads; heavy dust; uphill, downhill or mountain roads), but it attaches no mileage at all. There is nothing shorter to default to, so if any of that is your commute, err early. It is a glovebox job, which means erring early costs a filter, not shop labor.

On this generation

- Read the severe cell's wording, not just the letter beside it. The 2022 book's severe row for this filter reads "Replace more frequently depending on the condition". The 2025 book prints "Inspect more frequently depending on the condition" in the same cell while still marking the maintenance operation R, which is Hyundai's own code for Replace. Same part, same car, softer sentence. The R is what governs.

## 24,000–30,000 mi

### Engine air filter (no severe mileage is published, so this is the normal number)

$25–$60 DIY-realistic

Every 24,000 miles on the 2.0 MPI in every book from 2021 through 2025, and the same 24,000 on the 1.6 T-GDI and the Elantra N in every book that carries their schedules, which is 2022 onward. The Hybrid is the odd one out: 30,000 miles in the 2022 and 2023 books, tightened to 24,000 in the 2024 and 2025 books. At this bucket it is the first replacement, not the third, because Hyundai only inspects the filter at the 8,000-mile stops in between. The severe table lists the row under conditions C and E with the words "more frequently" and no mileage attached, so there is no shorter factory number anyone can quote you.

### Engine clutch actuator fluid (Hybrid only)

$100–$220 Shop job

No other CN7 has this line and most shops will not raise it. The Hybrid's 6-speed DCT couples the engine through a hydraulically actuated clutch, and Hyundai puts that hydraulic fluid on a replace clock of its own: "Replace every 26,000 miles (40,000 km) or 24 months" in the 2022 and 2023 books, and "Replace every 24,000 miles (39,000 km) or 24 months" plus an 8,000-mile inspection in the 2024 and 2025 books. The 2025 Hybrid's lubricants table specifies a DOT-4 LV / ISO Class 6 brake-grade fluid for it, listed as "As required", not a gear oil and not the 70W GL-4 that goes in the gearbox itself. If a Hybrid has never had this done past 26,000 miles, it is overdue by the book, not by a shop's opinion.

On this generation

- This is the item to name when a Hybrid quote looks thin. A dealer or independent working from a generic compact-car schedule will not have it on the menu, because nothing else Hyundai sells in this size class has a separate clutch actuator circuit. Ask for it by the book's own name, engine clutch actuator fluid, and ask which fluid is going in: the 2025 Hybrid manual's table gives SAE J1704 DOT-4LV / FMVSS 116 DOT-4 / ISO4926 Class-6, which is a brake-fluid grade, not an ATF.

## 42,000–48,000 mi

### Spark plugs, Elantra N 2.0 T-GDI (Hyundai normal schedule: every 42,000 mi)

$300–$430 Shop job

The N's book says "Replace every 42,000 miles (70,000 km)", identically in the 2022, 2023 and 2025 editions, which is less than half the 96,000 miles the volume 2.0 gets. A 276-hp turbo running higher cylinder pressure erodes the electrode faster, and Hyundai prices that in. On the severe side the N's table marks plugs R and then writes only "Replace more frequently depending on the condition" under A, B, F, G, H, I and K, with no mileage. Nobody can turn that into a number, and this ledger will not invent one; if the car sees track days or long idling, pull one and look at it before 42,000 rather than after.

### Spark plugs, 1.6 T-GDI N Line (Hyundai normal schedule: 47,000 mi in the 2022 book, 48,000 mi from 2023 on)

$300–$430 Shop job

This number moved by a thousand miles inside the generation and the direction matters less than knowing it moved. The 2022 book prints "Replace every 47,000 miles" for the Smartstream G1.6 T-GDi row; the 2023, 2024 and 2025 books all print 48,000. The 2021 book carries no turbo schedule at all, only the Smartstream G2.0 Atkinson, so it is silent here rather than contradictory: a 2021 N Line owner has no factory plug figure in their own book and should use the 47,000 from 2022. Either way it is roughly half the naturally aspirated 2.0's 96,000, and the severe table attaches no mileage to plugs on any engine.

### Brake fluid (Hyundai does publish a fixed replace mileage; no severe number exists)

$90–$180 Shop job

Unusually for Hyundai, this generation gets a hard number rather than an inspection: "Replace every 48,000 miles (78,000 km) or 48 months", with an inspection every 8,000 miles/12 months (6,000 on the Elantra N). One exception, and it is a big one: the 2022 and 2023 Hybrid books replace brake fluid every 20,000 miles on that book's 10,000-mile grid, inspecting at the 10,000-mile stops in between. The 2024 Hybrid book brings it back in line at 48,000. No severe-usage table in any book in this generation carries a brake-fluid row at all, so 48 months is the number regardless of how you drive, and brake fluid pulls moisture from the air on a calendar rather than an odometer.

On this generation

- The fluid spec is not plain DOT 3 or DOT 4. The manual's own footnote reads "(Standard: SAE J1704 DOT-4 LV, ISO4925 CLASS-6 and FMVSS 116 DOT-4)". That is DOT-4 LV, low viscosity, which the ABS and ESC hydraulics are calibrated around. A shop topping up from the generic DOT 3 jug on the shelf is not meeting the spec printed in the book, and on a Hybrid the same grade of fluid is what the engine clutch actuator circuit takes.

### Accessory drive belt (gas and N only; wear-based, not a fixed replace mileage)

$120–$260 DIY-realistic

Hyundai does not put this on a replace clock. The books say inspect at 48,000 miles (78,000 km) or 72 months first, then every 8,000 miles/12 months on the gas cars, or every 6,000 on the Elantra N, and the footnote is explicit: "The drive belt should be replaced when cracks occur or tension is reduced excessively." The 2022 book is the odd year, running the repeat inspection at every 16,000 miles/24 months instead of 8,000. The Hybrid has no accessory drive belt row at all; its equivalent is the HSG belt, which does carry a replace mileage and sits in the next bucket. 48,000 miles is a sensible first real look, not a deadline.

On this generation

- If a shop quotes a timing belt on any CN7, ask them to show you the interval in the book. Nothing in this generation's factory schedules mentions timing service in either direction, and published engine references disagree with each other about whether the 1.6 T-GDI is chain- or belt-driven, so no honest quote can rest on a factory interval that does not exist. The accessory belt above is the one this car actually has a printed line for.

### Front brake pads (wear-based, not a fixed manufacturer mileage)

$200–$380 DIY-realistic

Hyundai only ever inspects these: the normal schedule marks "Disc brakes and pads" I at every stop, and the severe table repeats it as "Inspect more frequently depending on the condition" under C, D, E, G and H, with no mileage. For an ordinary city and highway mix on a compact this light, front pads commonly need their first real set somewhere in the 30,000 to 60,000-mile range, sooner in the stop-and-go that also puts you on the severe schedule for everything above. The Elantra N uses a larger, different pad from the rest of the range, so confirm the trim before ordering. Hybrids run regenerative braking and typically go longer on the same pad than a gas car does.

## 56,000–80,000 mi

### IVT (CVT) fluid, all 2.0 MPI cars (severe-schedule default, and the only mileage Hyundai publishes)

$175–$320 Shop job

The normal schedule gives this no number at all: the IVT row reads "No check, No service required", which is fill-for-life framing. The only figure anywhere in the factory books is in the severe table, and it is "Replace every 60,000 mi. (90,000 km)" under conditions A, C, D, E, F, G, H, I and K. Read that list before dismissing it: repeated trips under 5 miles, dusty or gravel roads, salt or very cold weather, heavy dust, heavy traffic, mountain roads, towing, commercial use, and frequent stop-and-go. A short winter commute matches two of them without anyone calling their driving severe. Treat 60,000 as the real interval, not lifetime. This item does not apply to the Hybrid, the N Line or the Elantra N, which have their own boxes below.

On this generation

- Use Hyundai genuine SP-CVT1 and nothing else. The 2025 manual's lubricants table names it by that part spec and the schedule's own footnote says "Use only the specified intelligent variable transmission fluid." The manual's capacity table puts the system fill at 6.87 US quarts, which is worth knowing when you read a quote: a single drain-and-fill moves well under half of that, so ask how much fluid the price covers.
- This is the number an Elantra page got wrong before, so check any quote against the book. The severe row directly below the IVT is the dual clutch box at 80,000 miles, and in the 2022 book the row below that is rear differential oil at 72,000 on a car that has no rear differential. Reading the grid one line off is how a 2.0 IVT owner ends up on a 75,000 or 80,000-mile interval that Hyundai never published for their transmission.

### Dual-clutch fluid, 7-speed dry DCT (N Line only; severe-schedule default at 80,000 mi)

$200–$400 Shop job

The N Line's dry 7-speed is the same story as the IVT with a different number. The 2022, 2023 and 2024 books inspect the fluid every 32,000 miles on the normal schedule and the 2025 book drops even that, printing "No check, No service required". The severe table is where the mileage lives: "Replace every 80,000 mi. (120,000km)" under conditions C, D, F, G, H, I and J in the 2025 book, with E, sand and dust ingestion, also listed in the 2022 and 2023 books. The fluid is a 70W API GL-4 gear oil, 1.7 to 1.8 US quarts, not an ATF and not a wet-DCT fluid; putting either of those in a dry clutch pack is a rebuild, not a mistake you drive away from.

### Dual-clutch fluid, 6-speed Hybrid DCT (severe-schedule default at 80,000 mi)

$200–$400 Shop job

The Hybrid's 6-speed dry DCT takes the same 70W GL-4 gear oil and the same severe figure, "Every 80,000 miles (120,000 km)" under conditions C, D, E, F, G, H, I and J. What changed inside the generation is the normal schedule: the 2022 and 2023 books inspect the fluid at 40,000 and 80,000 miles, and the 2024 and 2025 books replace that with "No check, no service requied" (Hyundai's typo, not ours). Both editions add the same standing rule, "Dual Clutch Transmission (DCT) fluid should be changed anytime it has been submerged in water." If a Hybrid has been through a flooded street, that is a service call, not a wait-and-see.

### Gearbox fluid, Elantra N: 8-speed wet DCT at 56,000 mi, 6-speed manual at 72,000 mi (both severe-schedule defaults)

$350–$750 Shop job

The N's wet 8-speed carries the shortest transmission interval on the whole page: "Every 56,000 miles (91,000 km)", and its condition list is the longest in the book, A through K in the 2022 edition. That is the only CN7 gearbox Hyundai effectively expects to be serviced on an ordinary owner's timeline. The 6-speed manual reads "No Check, No Service required" on the normal schedule and "Every 72,000 miles (120,000 km)" on the severe one under C, D, E, F, G, H, I and J. Budget the wet DCT properly: it holds two separate fluids, roughly 3.4 to 3.6 US quarts of gear oil and another 2.58 to 2.64 US quarts of hydraulic control oil, both Hyundai-specific, and they are not interchangeable with each other or with the dry-DCT 70W. One exception worth knowing, because it is the only normal-schedule gearbox number anywhere in this generation: the 2022 and 2023 gas books print a manual transmission fluid row at 40,000 miles normal and 80,000 severe, marked "(if equipped)". It is gone from the 2024 and 2025 books. If you drive a manual N Line from those years, that row is yours.

On this generation

- A tracked N is a severe-schedule car by Hyundai's own definition before anyone argues about it. Condition J in the 2025 N book is frequent driving at high speeds or rapid acceleration and deceleration, and condition G is uphill, downhill or mountain roads. Either one alone puts the wet DCT on the 56,000-mile clock and the engine oil on 3,000 miles. If you are buying a used N, ask for gearbox fluid records, not just oil records.

### Valve clearance inspection (Elantra N only; Hyundai publishes an interval for this engine and no other)

$120–$260 Shop job

The N's 2.0 T-GDI is the only engine in this generation with a scheduled valve-clearance line: "Inspect every 60,000 miles (90,000km) or 72 months", with the footnote "Inspect for excessive valve noise and/or engine vibration and adjust if necessary." It is an inspection, not an automatic adjustment, and the book sends it to a dealer. The 2.0 MPI, the 1.6 Hybrid and the 1.6 T-GDI have no valve-clearance row in any of their books, so a valve-adjustment quote on a non-N CN7 has no factory interval behind it.

### HSG (Hybrid Starter & Generator) belt, Hybrid only (a real replace mileage, unlike the gas car's belt)

$150–$350 Shop job

This is the Hybrid's accessory belt and it is the one item where the Hybrid is harder on the wallet than the gas car: the gas Elantra's drive belt is inspect-until-it-cracks, while the Hybrid's HSG belt is a scheduled replacement. The 2022 and 2023 books inspect every 7,500 miles "and replace every 67,500 miles (108,000 km) or 48 months." The 2024 and 2025 books move to the 8,000-mile grid and read "and replace every 64,000 miles (104,000 km) or 48 months." Note the 48 months: that is a calendar limit, so a low-mileage Hybrid still needs it. Under severe conditions B, C, D, E, I and K the 2025 book brings replacement forward to every 30,000 miles (48,000 km) or 24 months.

On this generation

- The HSG belt is not a comfort item on this car. It is the belt between the engine and the starter-generator that does the engine starting and stopping the Hybrid does hundreds of times a day, which is why Hyundai gives it a replace mileage and a 48-month calendar cap rather than the gas car's inspect-and-see. The same footnote tells you what to do about noise first: "If drive belt noise occurred, readjust drive belt tension before replace."

## 60,000–100,000 mi

### Shocks and struts (wear-based, no manufacturer interval)

$700–$1,500 Shop job

Hyundai publishes nothing here. The books inspect suspension mounting bolts and ball joints at every stop and stop there. Generic wear life on a compact sedan runs roughly 50,000 to 100,000 miles depending on road surface and how the car is driven, and nothing generation-specific turned up beyond that. The interaction that matters: worn struts let the tire's contact patch bounce, which cups and scallops tread unevenly on its own, independently of whether the alignment is in spec. If you are chasing odd tire wear and the alignment printout checks out, look here before blaming the tires or the alignment shop. Replacing struts also shifts ride height and geometry, so budget the alignment below as part of the job, not as an upsell.

### CV axle boots: inspect (replace the axle if a boot has torn)

$450–$650 Shop job

Not on Hyundai's schedule as a replacement, but the books do inspect "Driveshaft and boots" at every stop on the 2021 and 2023 grids and every 16,000 miles on the 2024 and 2025 grids, and the severe table repeats it under C, D, E, F, G, H, I and J. Boot rubber hardens and splits with age as much as mileage, so start actually looking at 60,000 miles or five years, whichever comes first. Typical boot life runs roughly 70,000 to 130,000 miles. This is not just an axle problem: a torn boot slings joint grease outward as the shaft spins, and on a front-drive transverse layout that grease lands on the inboard face of the front rotor and pad, so a boot ignored for a few thousand miles turns one repair into two. Clicking on sharp turns means you already waited too long.

## 70,000–120,000 mi

### Control arm bushings (wear-based, no manufacturer interval)

$300–$800 Shop job

Also absent from the factory schedule, which only inspects the lower and upper arm ball joints. Generic wear life runs roughly 70,000 to 120,000 miles in normal use and 50,000 to 80,000 on rough roads or in a salt-and-freeze climate, and rubber perishes on a calendar too, so an eight-to-ten-year-old CN7 can need them at low mileage. Here is the interaction worth paying for: worn bushings let the suspension geometry shift under load, so an alignment done on tired bushings does not hold. The car drifts back out of spec within weeks even though the machine said it was correct. If a car has needed two alignments in a season, check the bushings before buying a third. Most independents replace the whole lower arm with bushings pre-pressed rather than pressing new rubber into the old arm.

### Engine and transmission mounts (wear-based, no manufacturer interval)

$300–$420 Shop job

No factory interval and no documented generation-specific weak point on the CN7, which is worth saying plainly rather than inventing one. Rubber and hydraulic mounts degrade with age and torque load; typical replacement windows run 80,000 to 150,000 miles, sooner on the 201-hp N Line and the 276-hp N and sooner again on stop-and-go duty. The cascade is the reason not to defer one: a collapsed or torn mount lets the engine move, and that movement works on everything bolted to it, exhaust connections and flex pipes, hoses, wiring, and the remaining mounts, which now carry load they were not designed for. Skipping one worn mount is how an owner ends up paying for two mounts and an exhaust flex pipe. Symptoms an owner actually notices: a clunk shifting into drive or reverse, vibration at idle in gear, and an engine lurch under throttle.

## 96,000–102,500 mi

### Spark plugs, 2.0 MPI (Hyundai normal schedule: every 96,000 mi)

$280–$400 DIY-realistic

Every book from 2021 to 2025 prints 96,000 miles for the Smartstream G2.0 Atkinson row, and that figure has not moved once in the generation. This is a low-stress port-injected engine running iridium plugs specified for that life on purpose, so pulling the set at 60,000 because a shop's generic schedule says so throws away nearly 40 percent of a part engineered to go the distance. The severe table marks plugs R and then writes only "more frequently depending on the condition" under A, B, F, G, H, I and K, with no mileage attached to any engine. If your driving matches those, pull one plug and look at it rather than replacing the set on a date somebody made up.

### Spark plugs, 1.6 Hybrid (Hyundai normal schedule: 102,500 mi in 2022 and 2023, 96,000 mi from 2024)

$280–$420 Shop job

The Hybrid carries the longest plug interval on the page and it changed at the facelift, along with the whole grid. The 2022 and 2023 Hybrid books read "Replace every 102,500 miles (165,000 km)" on a 10,000-mile grid; the 2024 and 2025 books read "Replace every 96,000 miles (156,000 km)" on an 8,000-mile grid. Both editions add the same convenience note, that the plugs can be replaced before the interval when other work brings the top of the engine apart, which on a Hybrid is worth taking: labor access is the expensive part, not the plugs. Look up your own model year rather than assuming the 102,500.

## 120,000 mi

### Engine coolant, first service (then every 24,000–30,000 mi, and the repeat changed inside the generation)

$150–$450 Shop job

Every book in this generation puts the first coolant service at 120,000 miles, though the books differ on the parenthetical, some printing no kilometre figure, one printing 195,000 km and the Elantra N book printing 10 years rather than 120 months, which is a long first interval consistent with Hyundai's phosphate-based long-life coolant. The repeat afterwards moved: the 2021 and 2022 books read "Thereafter, replace every 30,000 miles or 24 months" and the 2024 and 2025 books read "After that, replace every 24,000 mi. (39,000 km) or 24 months", and the 2023 book says the same thing spelling out the word miles. The Hybrid did not follow the same path: it runs 30,000 in the 2022 book, drops to 20,000 in the 2023 book, and settles at 24,000 from 2024. Check your own year. No severe-usage table in any book in this generation carries a coolant row, so the normal number applies regardless of driving pattern. Capacity is 7.82 US quarts on the 2.0, 7.19 on the 1.6 T-GDI and 7.93 on the Elantra N.

On this generation

- A Hybrid has two coolant circuits and a quote that mentions one number is a quote for half the job. The 2025 Hybrid manual lists engine coolant at 6.23 US quarts and a separate inverter coolant at 2.22 quarts, both on the same 120,000-mile-then-24,000-mile schedule. The inverter loop cools the power electronics, not the engine, and it does not get touched by a normal engine-coolant service.
- Use deionized or soft water if anything is topped up. The Hybrid book's coolant footnote is explicit: "When adding coolant, use only deionized water or soft water for your vehicle and never mix hard water in the coolant filled at the factory." Hard tap water is the cheap shortcut that leaves deposits in an aluminum radiator, and this is one of the few places Hyundai bothers to spell out the failure.

## Ongoing: event-triggered, not a fixed mileage

### Wheel alignment

$90–$180 Shop job

Not a manufacturer mileage item and it appears in no CN7 schedule. It is triggered by events: any time new tires go on, and after any suspension work, struts, control arms or an axle. Skipping it after either wastes part of what you just spent, because new tires wear unevenly from day one on a car that is out of spec, and new suspension parts installed against stale geometry put the car back where it started. Beyond that, a check every 12,000 to 15,000 miles or annually catches curb strikes and potholes before they show up as tread wear. If a CN7 needed a second alignment shortly after the first, look at the control-arm bushings above before blaming the alignment shop.

### Tires: match them to how the car is actually used

$450–$900 Shop job

The CN7 is a front-drive commuter sedan. The 2025 manual's tire tables run from 195/65R15 on the base car up to 235/40R18, and there is no all-wheel-drive variant anywhere in this generation, so no tread-depth-matching rule across axles applies. A standard all-season touring tire is right for nearly every owner. There is no off-road case for this car to justify an all-terrain tread, and the downside is real: worse wet and wintry grip on pavement, faster and more uneven wear, more noise, no upside. The Elantra N sits outside this guidance, since a performance trim's factory fitment is chosen for grip rather than tread life; match what is actually on that car. This ties straight back to the two items above: uneven wear that looks like a bad tire choice is often worn struts or a stale alignment, so check those before condemning the tire.

On this generation

- The rotation grid is not the same across the range and a shop working off one schedule will get it wrong on the other. The gas cars rotate every 8,000 miles or 12 months, and so does the Hybrid from the 2024 book on, but the 2023 Hybrid book asks for 10,000 and the 2022 Hybrid book carries no rotation row at all, only an inspection; the Elantra N rotates every 6,000 miles, and its row is worded "Rotate Tires (includes tread wear inspection and tire pressure check)", so the rotation is also when the book expects someone to actually measure the tread.

### Wiper blades (wear and weather, no factory interval)

$25–$60 DIY-realistic

No CN7 schedule carries a wiper row, so this is entirely a condition call, typically once a year and sooner in a hot or salt-heavy climate. Sizes on this generation are 24 inches driver and 18 inches passenger on 2021–2023 cars, with one 2023 fitment chart listing a 17-inch passenger blade, so measure the blade on the car rather than trusting a chart. The sedan has no rear wiper. Facelift 2024-and-later cars have not been verified here, so check yours before ordering a pair.

## 5 years (any mileage)

### 12V battery (calendar-based, not mileage-based)

$180–$400 DIY-realistic

The gas and Elantra N schedules only ever inspect battery condition, at every stop, and attach no replacement mileage; the Hybrid schedule carries no battery row at all, only a blanket "All electrical systems" inspection. Treat it as a calendar item: average lifespan is 3 to 5 years regardless of the odometer, so start load-testing around year 3 and replace proactively by year 5 whether or not it has misbehaved. The gas cars take a BCI Group 47 (H5), roughly 650 to 680 cold-cranking amps, AGM or EFB. The Hybrid's 12V differs by trim, so verify that one by VIN rather than assuming the gas car's group. Get the group size and CCA right wherever you buy: a wrong group either does not sit in the tray or comes up short on cold-cranking amps in winter.

On this generation

- On this generation a weak 12V is not just a no-start risk, it is the first thing to rule out on the documented warning-light storm. Owners of 2021–2022 cars report multiple warnings lighting at once, sometimes with power-steering assist dropping out, and a marginal battery is the cheapest of the documented causes. That changes the decision: on a CN7 showing cluster gremlins, a load test comes before anyone opens a diagnostic ticket on the EPS column.
- On retailer choice, one thing is checkable and one thing is not. Some independent battery dealers claim the big-box chains get a lower-tier version of the same brand; that claim is contested and is not repeated here as fact. What is real and worth comparing before you hand over a card is the warranty: length and free-replacement-versus-prorated structure genuinely differ by retailer for the same battery brand, so read the warranty card, not just the price tag.
