# Jeep Grand Cherokee 2011–2021 Common problems, reliability & repair costs

The WK2 Grand Cherokee looks and drives like a near-luxury SUV at a used-truck price, and that's exactly the trap. The good ones are the later, simply-equipped 3.6L cars. The expensive ones are early-build electrical gremlins (the TIPM), cylinder-head wear on 2011–2013 Pentastars, the Quadra-Lift air suspension that fails out of warranty, and the EcoDiesel's cooler problems. Buy on options and build year, not just mileage.

Verdict

## Should I buy a 2011–2021 Jeep Grand Cherokee?

Buy a late one, lightly optioned, and you'll be fine; buy an early loaded one and you're rolling the dice on four separate expensive systems. The sweet spot is a 2017–2021 3.6L Laredo or Limited on coil springs (not air), without the EcoDiesel. Those are genuinely good used SUVs. The cars to be careful with are 2011–2013 (TIPM electrical, early Pentastar heads), anything with Quadra-Lift air suspension (it fails out of warranty and is thousands to fix), and the EcoDiesel unless its EGR-cooler recall is done and the oil cooler has been addressed. A clean later 3.6L on steel springs is a different ownership experience than an early air-sprung diesel.

Best years

2017, 2018, 2019, 2020, 2021

Years to avoid

2011 (worst year: TIPM electrical, early Pentastar heads), 2014 (8-speed shift complaints, EcoDiesel cooler issues, recall-heavy), 2012–2013 (early Pentastar head wear)

Inspection Companion

### Pre-Purchase Checklist for Jeep Grand Cherokee

[Open Field Checklist Page ->](https://carcasefile.com/vehicles/jeep-grand-cherokee-2011-2021/checklist/)

- ☐ On 2011–2013 3.6L cars: cold-start it and watch for a check-engine light / rough idle. Pull codes. P0300/P0302/P0304/P0306 (left-bank misfires) point at the known cylinder-head wear.
- ☐ On any 2011–2013 car: test EVERY electrical function: remote start, power locks, horn, wipers, fuel pump priming. Erratic behavior or no-start/hard-start is the classic TIPM symptom. Check the VIN for recalls 14V-530, 15V-115 and 19V-813 (fuel pump relay in the TIPM).
- ☐ Confirm whether the car has Quadra-Lift AIR suspension or steel coil springs. With the engine running, watch it raise/lower through its modes and listen for a constantly-running compressor or a 'Service Air Suspension' message.
- ☐ On the EcoDiesel: confirm the EGR-cooler recall (NHTSA 20V-699 / FCA W79) was completed by VIN, and ask about oil-cooler history. Look for coolant loss with no external leak.
- ☐ On 2014-2021 cars: test-drive at light throttle 40–60 mph and through stop-and-go. Harsh 1-2/2-1 shifts or a shudder at lockup is the 8-speed complaint. Ask if TCM software is up to date.
- ☐ Pull up the carpet edges (front and rear footwells) and smell for must/mildew. The WK2 has a well-documented sunroof-drain/cowl water-leak problem that ruins electronics.
- ☐ Check service records for cooling work; overheating from thermostat/EGR-cooler issues is common on heavily-complained years.

Known faults

## Common Jeep Grand Cherokee problems & repair costs

### TIPM (Totally Integrated Power Module) failure

$600–$1,400

electrical severe 2011–2013 (worst on 2011) ~40k–90k mi

**Symptoms:** Hard-start or no-start (often a stuck/failed fuel-pump relay), random electrical gremlins: doors locking themselves, horn or alarm going off, wipers running on their own, dead battery from a relay that won't shut off.

**Fix:** Replacement TIPM (programmed to the VIN) or a rebuilt unit; some owners do a fuel-pump-relay bypass as a cheaper interim fix for the most common no-start failure. The 2011 model has the most TIPM complaints on CarComplaints. Check the VIN for recalls 14V-530, 15V-115 and 19V-813 (fuel pump relay in the TIPM).

Sources: [JeepProblems: Faulty TIPM](http://www.jeepproblems.com/tipm/), [CarComplaints: Jeep Grand Cherokee](https://www.carcomplaints.com/Jeep/Grand_Cherokee/)

### 3.6L Pentastar left cylinder-head wear (misfires)

$1,500–$4,000

engine severe 2011–2013 ~60k–120k mi

**Symptoms:** Persistent misfire on the left bank (cylinders 2, 4, 6; codes P0302/P0304/P0306), rough idle, hesitation, loss of power, check-engine light. Caused by premature valve-guide and valve-seat wear.

**Fix:** Cylinder-head replacement (typically the left head). FCA issued TSB 09-002-14 and an extended warranty on affected 2011–2013 engines. Many were repaired free. Confirm by VIN. Out of coverage, it's a real head job.

Sources: [Autoevolution: Pentastar V6 left cylinder head failure](https://www.autoevolution.com/news/pentastar-v6-still-prone-to-cylinder-head-failure-82615.html), [Go-Parts: P0306 cylinder 6 misfire (2011–2018 GC)](https://www.go-parts.com/garage/obd-p0306-jeep-grand-cherokee-2011-2018)

### Quadra-Lift air suspension failure

$1,200–$5,000

suspension moderate 2011–2021 (air-equipped only) ~60k+ mi

**Symptoms:** 'Service Air Suspension' message, corner(s) sagging or won't raise, compressor running constantly or burned out, leaking air lines/struts. Failure rate climbs after about 60k miles.

**Fix:** Diagnose the actual leak first. It's often the front air-spring limit valves or harness, not the compressor everyone blames. Repairs range from a compressor (around $2,000+) to front air springs ($3,600–$5,000 at a dealer). A coil-spring conversion kit is a common out-of-warranty alternative.

### EcoDiesel EGR cooler and oil cooler failure

$1,000–$4,000

engine safety 2014–2019 (3.0L EcoDiesel, the 20V-699 EGR cooler recall scope) ~60k–120k mi

**Symptoms:** EGR cooler: thermal fatigue cracks it internally, letting coolant into the intake, a documented fire risk (subject of a federal recall). Oil cooler: coolant loss with no external leak; left unaddressed it can kill the engine.

**Fix:** The EGR cooler is covered by recall NHTSA 20V-699 (FCA W79, 2014-2019 Grand Cherokee 3.0L). Dealers replace the cooler (and inspect the intake) free. The oil cooler is NOT recalled despite widespread failures; budget for replacement, and don't ignore unexplained coolant loss on a diesel.

Sources: [NHTSA Recall 20V-699 / EGR cooler report (PDF)](https://static.nhtsa.gov/odi/rcl/2020/RCRIT-20V699-5780.pdf), [JeepGarage: EcoDiesel oil cooler failure killed the engine](https://www.jeepgarage.org/threads/eco-diesel-oil-cooler-failure-killed-the-engine.242754/)

### ZF 8-speed harsh shifting / torque-converter shudder

$200–$4,000

transmission moderate 2014–2021 ~any

**Symptoms:** Jerky 1-2/2-1 and low-gear shifts, delayed engagement into drive/reverse, and a light-throttle shudder around 40–60 mph from torque-converter lockup slip.

**Fix:** Start with a TCM software update and adaptive-learn reset (TSBs 18-034-20 and 21-013-21 address shift quality). That is cheap and often enough. Persistent cases trace to the valve body / mechatronic unit, which is the expensive end.

### Sunroof-drain / cowl water leaks

$150–$2,000

body moderate 2011–2020 ~any

**Symptoms:** Wet carpet or floor pan (front or rear), musty smell, mold, and shorted electronics. Sunroof control modules, airbag sensors in the headliner, and interior lighting harnesses can fail when water tracks in.

**Fix:** Clear or reroute the sunroof drains and reseal the cowl/leak point first (cheap if caught early). The big bills come from drying out the interior and replacing electronics the water already killed. No recall, but multiple TSBs and class-action suits exist.

Sources: [JeepGarage: multiple water-leak sources, passenger floor](https://www.jeepgarage.org/threads/multiple-sources-of-water-leaks-passenger-floor-and-behind-dash.245215/), [Edmunds: Jeep Grand Cherokee water leaks](https://forums.edmunds.com/discussion/11352/jeep/grand-cherokee/jeep-grand-cherokee-water-leaks)

This is a more expensive SUV to own than its used price suggests, and the spread is huge depending on how it's equipped. A late 3.6L on coil springs is reasonable: normal SUV wear (brakes, tires, fluids) plus the occasional ignition coil or thermostat. Air suspension, the EcoDiesel, or an early electrical-troubled car each add a category of multi-thousand-dollar risk. The V8s drink fuel and eat tires and brakes; the SRT/Trackhawk are specialist machines. Whatever you buy, the WK2 rewards buying the simplest, latest version you can find and punishes buying the loaded early one.

DIY repairs

## How to fix common Jeep Grand Cherokee problems (DIY)

### Replace ignition coil pack(s) on the 3.6L Pentastar

easy 30–60 min saves ~$80–$200

**Tools:** Socket set (8–10mm), Small extension, Flat screwdriver (connector clips)

- Pull the codes to identify the misfiring cylinder(s). Note: persistent left-bank misfires can be the head issue, not just a coil. Rule that out first.
- Remove the engine cover and locate the coil on top of the affected cylinder.
- Unclip the electrical connector and remove the single hold-down bolt.
- Pull the old coil straight up; transfer or replace the spark plug if it's due.
- Seat the new coil, reinstall the bolt and connector, and clear the codes.

### Clear the sunroof drain tubes

easy 30–45 min saves ~$100–$250

**Tools:** Compressed air or a weed-trimmer line, Shop towels, Plastic trim tool

- Open the sunroof and locate the drain holes in the front corners of the sunroof tray.
- Gently feed compressed air (low pressure) or a soft trimmer line into each drain to dislodge debris.
- Confirm flow by pouring a small amount of water into the tray and watching it exit below the vehicle (front by the wheels).
- Dry any standing water in the footwells and check that the carpet underneath isn't already soaked.

- [Sunroof drain cleaning tool kit](https://carcasefile.com/go?u=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dsunroof%2Bdrain%2Bcleaning%2Btool) · Amazon $8–$15

### Replace the front air-spring (Quadra-Lift) with a coil-spring conversion

hard 3–6 hrs saves ~$400–$1000

**Tools:** Floor jack + jack stands, Spring compressor (if reusing struts), Socket and wrench set, Torque wrench

- Diagnose first. Confirm the air spring/strut is the leak and not a valve or harness, so you don't convert unnecessarily.
- Safely lift and support the vehicle and remove the wheel.
- Disconnect the air line and electrical connector, then unbolt the top mount and lower strut bolts.
- Remove the air strut and install the coil-spring conversion strut per the kit instructions.
- Repeat per corner as needed, then deal with the suspension warning (most kits include a bypass module to silence the air-system fault).
- Torque everything to spec, reinstall wheels, and verify ride height and no warning lights.

## The short version

The 2011–2021 Jeep Grand Cherokee (the WK2) is one of the best-value used SUVs on paper and one of the easiest to overpay for in practice. It looks and rides like something far more expensive, and that’s the problem. Air suspension, the EcoDiesel, and a stack of early electronics are what make it feel premium, and they are exactly the parts that turn into four-figure repair bills once the warranty is gone.

Sort the WK2 into two piles. The good pile is the later, lightly-equipped 3.6L on steel coil springs. The risky pile is anything early (electrical TIPM trouble, 2011–2013 Pentastar head wear), anything with Quadra-Lift air suspension, and the EcoDiesel.

## What that means when you’re shopping

If you’re looking at a **2017–2021 3.6L Laredo or Limited on coil springs**, you’ve sidestepped most of the landmines. Buy it like any used SUV: condition, records, a clean transmission test-drive.

If you’re looking at a **2011–2013 car**, treat the electrical system and the engine as the two things to clear first. Test every electrical function for the TIPM, and pull codes for left-bank misfires (P0302/P0304/P0306) for the head issue. A dealer can check by VIN whether the head warranty extension was already used.

If the car has **air suspension or the EcoDiesel**, price in the risk. Air suspension fails out of warranty and costs thousands; the diesel’s EGR cooler is a recalled fire risk and its oil cooler isn’t recalled at all. Neither is a dealbreaker on a documented, sorted example. But on an unknown one, they’re how a cheap Jeep becomes an expensive one.

Everything else is ordinary big-SUV ownership: brakes, tires, fluids, the occasional coil pack, and keeping the sunroof drains clear so water never reaches the electronics.

Myths, checked

## Viral car myths, checked against this car

Misleading

### [Is the "$2 liquid that stops any leak" really banned in 11 states?](https://carcasefile.com/claims/2-dollar-stop-leak-banned-11-states/)

Automotive stop-leak products are not banned in any US state. The products are real (Bar's Leaks, BlueDevil), they work in specific narrow situations, and they can permanently damage your cooling or oiling system if applied to the wrong leak.

Dangerous

### [Is the "$2 liquid that destroys engine sludge forever" real? Our shop-floor verdict.](https://carcasefile.com/claims/2-dollar-engine-sludge-destroyer-liquid/)

An aggressive solvent flush on a high-mileage engine is a textbook way to spin a bearing. The viral 'kitchen-cabinet flush' is folklore that real shops spend money cleaning up after.

Outdated

### [Does a "$1 mineral" really double car battery life? The Epsom-salt reality.](https://carcasefile.com/claims/1-dollar-mineral-doubles-battery-life-myth/)

The mineral is Epsom salt (magnesium sulfate). It was a real desulfation hack for serviceable flooded-cell batteries 40+ years ago. It does not work on modern sealed AGM or EFB batteries, and trying it on yours will void the warranty without helping the battery.

## Frequently asked questions

### Which Jeep Grand Cherokee years should I avoid?

2011 is the worst. It has the most TIPM electrical complaints and is an early Pentastar with the head-wear risk. 2012–2013 share the head issue, and 2014 is recall-heavy with the new 8-speed's shift complaints and EcoDiesel cooler problems. The 2017–2021 3.6L cars are the safer used buy.

### Is the 3.6L Pentastar cylinder-head problem covered?

On affected 2011–2013 engines, FCA extended the warranty for the left-head misfire issue, and many were repaired free. If the extension no longer covers a car, the head job is on you, so it matters before you buy. Confirm by VIN whether the repair was already done.

### Should I buy a Grand Cherokee with air suspension?

Only with eyes open. Quadra-Lift rides nicely but fails out of warranty, and repairs run from about $1,200 to $5,000 depending on what's actually leaking. If you don't need the off-road height adjustment, a coil-spring car is cheaper to live with, or budget for a conversion kit down the road.

### Is the EcoDiesel worth it?

It has great torque and range, but only buy one where the EGR-cooler recall (NHTSA 20V-699) is documented as completed and you've checked the oil-cooler history. Those two cooler failures are the diesel's signature problems, and the oil cooler isn't covered by any recall.

### How reliable is the WK2 Grand Cherokee overall?

It's middling: better than its reputation if you pick a late, simply-equipped 3.6L, and worse than its reputation if you buy an early loaded car with air suspension or the diesel. The platform's value is real; the risk lives in the options and the build year.
