# Ford Explorer 2011–2019 Common problems, reliability & repair costs

The 5th-gen Explorer is where Ford turned the Explorer into a car-based, front-drive crossover. It's roomy, comfortable, and common, but it carries two expensive design traps: a timing-chain-driven internal water pump on the V6 that can dump coolant into the oil, and an AWD power transfer unit (PTU) that cooks its own fluid and self-destructs. Add a years-long carbon-monoxide-odor saga and you have an SUV you buy carefully, not blindly.

OEM part
Motorcraft

BCI Group 65, 650 CCA. Ford's 2016 and 2019 manuals list BXT-59 as the standard battery and BXT-65-650 for vehicles with Intelligent Access; the 2013 manual lists only BXT-65-650, so this may be a running change. Higher-electrical trims take higher-CCA Group 65 (up to ~850 CCA); some lower-content trims list Group 59. NOT the H6/Group 48 of the 2020+ 6th gen.

Verdict

## Should I buy a 2011–2019 Ford Explorer?

Buy it with your eyes open. A clean, well-documented 5th-gen Explorer is a comfortable, practical family hauler with cheap, everywhere-available parts. But this generation has two big-ticket design problems that decide whether you got a deal or a project: the V6's internal, timing-chain-driven water pump (a four-figure job that can ruin the engine if it leaks coolant into the oil), and the AWD PTU that overheats and fails when nobody changes its 'lifetime' fluid. FWD cars sidestep the PTU entirely and are the lower-risk buy. Whatever you pick, check open recalls by VIN. The rear suspension toe-link and the carbon-monoxide-odor service actions both apply to large swaths of these years.

Best years

2018, 2019

Years to avoid

2011 (first model year, most teething bugs), 2013 (highest complaint volume of the generation), 2016 (transmission and odor complaints peak)

Inspection Companion

### Pre-Purchase Checklist for Ford Explorer

[Open Field Checklist Page ->](https://carcasefile.com/vehicles/ford-explorer-2011-2019/checklist/)

- ☐ On any V6: pull the oil cap and dipstick and look for a milky, coffee-with-cream film. That's coolant in the oil from a failing internal water pump. Walk away if you see it.
- ☐ Check the coolant level and look for unexplained coolant loss; the water pump weeps internally, so there may be no puddle under the car.
- ☐ On AWD cars: sniff for a hot, burnt-gear-oil or 'propane' smell after a drive and look for dark fluid leaking on the passenger side near the back of the engine. That's a classic dying PTU.
- ☐ Run the A/C and heater and pay attention to any exhaust odor in the cabin, especially under hard acceleration with windows up. That's the long-running CO-odor complaint.
- ☐ Drive it from a rolling stop and through 1–2 gear changes; feel for a hesitation-then-harsh-bump shift, the known 6F50 valve-body symptom.
- ☐ Run the VIN through NHTSA and a Ford dealer for open recalls. Rear suspension toe-link and exhaust/odor service actions are common on these.
- ☐ Watch for the door-ajar warning staying lit with all doors shut (a known nuisance fault) and any 'steering assist fault' message.

Known faults

## Common Ford Explorer problems & repair costs

### Internal water pump failure (V6, timing-chain-driven)

$1,500–$3,500

engine cooling severe 2011–2019 (3.5L N/A and 3.5L EcoBoost V6) ~80k–150k mi

**Symptoms:** Slow, unexplained coolant loss with no external puddle (the pump weeps inside the engine). In the worst case, coolant gets past the seal into the oil, which can destroy the engine. The oil turns milky, like a blown head gasket. Sometimes overheating or a low-coolant warning is the only clue.

**Fix:** The pump sits behind the front timing cover and is driven by the timing chain, so reaching it means tearing into the front of the engine: roughly 10.8 book hours on the N/A V6 and 12.3 on the EcoBoost. Replace the pump (and inspect the timing components while you're in there). If coolant already contaminated the oil, you may be looking at engine replacement ($5,000–$7,000), which can total an older one.

### AWD Power Transfer Unit (PTU) failure

$1,200–$2,500

drivetrain severe 2011–2019 (AWD only) ~70k–130k mi

**Symptoms:** A hot, burnt or 'propane'-like smell in the cabin after driving (overheated fluid vented onto the hot exhaust), a speed-dependent whine or growl that rises with speed, grinding or clunking on acceleration and turns, and a dark, thick fluid leak on the passenger side at the back of the engine. Left alone it can seize and damage the transmission.

**Fix:** The PTU holds less than a quart of so-called 'lifetime' gear oil and sits jammed against the transmission and catalytic converter, so heat cooks the fluid and it never gets changed. Replace the unit (and its seals); the real fix going forward is servicing the PTU fluid roughly every 30k miles with full-synthetic 75W-140 to keep a healthy unit alive.

### Exhaust / carbon-monoxide odor in the cabin

$200–$1,000

exhaust / HVAC safety 2011–2018

**Symptoms:** Exhaust smell inside the cabin, most noticeable under hard acceleration with the windows up and the climate system recirculating. Owners reported headaches, nausea, and lightheadedness; the issue drew thousands of complaints and a multi-year federal investigation.

**Fix:** NHTSA reviewed ~6,500 complaints across 2011–2017 (with 2018 reports too) and closed the probe without a recall, finding measured CO levels below health standards in properly sealed vehicles. Ford's service response: inspect/seal rear liftgate gaskets and drain valves, fix any leaks, and reprogram the HVAC to bring in more fresh air. The worst odor cases traced to rear-crash sealing damage or aftermarket upfitting (police units).

### 6F50/6F55 6-speed harsh shifting (valve body)

$400–$2,500

transmission moderate 2011–2019 ~60k–120k mi

**Symptoms:** Hesitation or sluggishness from a rolling stop followed by a harsh bump or slip as it engages, plus hard or jerky shifts and occasional slipping. Transmission is the most-complained-about system on the generation.

**Fix:** Many cases are a known valve-body design issue (addressed by a separator-plate/check-ball modification or a revised valve body) plus a fluid service. Neglected fluid that overheats can escalate to internal damage and a rebuild, which is the high end of the range.

Sources: [Transmission Repair Cost Guide: Explorer](https://www.transmissionrepaircostguide.com/ford-explorer-transmission-problems/), [Lemon Law Group Partners: Explorer transmission](https://lemonlawgrouppartners.com/ford-explorer-transmission-problems/)

### Rear suspension toe-link fracture

$0–$600

suspension safety 2013–2019

**Symptoms:** A clunk from the rear, unusual handling, or a rear wheel that looks misaligned. A fractured toe link can cause loss of steering control. Corrosion of the rear cross-axis ball joints (worse in road-salt regions) stresses the welds until they crack.

**Fix:** Covered by multiple Ford recalls across these years. Check the VIN; recall repair is free at a dealer. Outside recall coverage, replacing the toe links and an alignment is the fix. Always confirm the recall status before buying.

### Persistent door-ajar warning

$150–$400

electrical minor 2011–2019

**Symptoms:** Door-ajar light stays on with all doors closed, which also keeps the dome light on and can drain the battery. Caused by a worn door latch/ajar switch, usually a single door, often a rear one.

**Fix:** Replace the failing door latch assembly (which contains the ajar switch). A common, well-documented fix; identify the offending door first by working each latch by hand.

Sources: [Ford Explorer Forums: door-ajar solved](https://www.explorerforum.com/forums/threads/door-ajar-solved.495523/), [StartMyCar: Explorer door problems](https://www.startmycar.com/us/ford/explorer/problems/door)

Routine ownership is cheap. Parts are everywhere, this was a best-seller, and most maintenance is ordinary. What blows the budget on a 5th-gen Explorer are the two design traps: the V6 internal water pump (four figures because of the labor to reach it) and the AWD PTU (which fails if nobody services the 'lifetime' fluid). A FWD car has no PTU and is the cheapest version to keep. If you buy AWD, budget for a PTU fluid service every ~30k miles and treat it as required maintenance, not optional. Keep an eye on transmission fluid condition too. Neglect there turns a valve-body annoyance into a rebuild.

DIY repairs

## How to fix common Ford Explorer problems (DIY)

### AWD PTU fluid: why there is no DIY procedure here

pro-only

- We do not publish a fill-and-drain procedure for this PTU. On many years of the 5th-gen Explorer it has no fill hole, and some years have no drain plug either (explorerplatinum.com and a Ford Explorer Forums owner thread, both linked in the maintenance schedule above). The usual gearbox method, remove the fill plug first and pump fluid to the fill hole, cannot be followed on those units.
- Have a shop that has serviced Explorer PTUs before do it. Ask how they will refill your unit before you book.

### Replace a door latch to clear the door-ajar warning

moderate 1–2 hrs saves ~$120–$250

**Tools:** Trim/panel removal tools, Torx + socket set, Painter's tape (to mark connectors)

- Identify the offending door by cycling each latch by hand and watching the dash warning.
- Remove the interior door panel and peel back the moisture barrier.
- Disconnect the latch wiring and linkage, then unbolt the latch from the door's rear edge.
- Install the new latch, reconnect linkage and wiring, and verify the door-ajar light goes out before reassembling.
- Reinstall the moisture barrier and door panel.

### Cabin & engine air filter change

easy 20 min saves ~$60–$120

**Tools:** Screwdriver (cabin filter cover)

- Open the glovebox, release the stops to drop it down, and remove the cabin filter cover.
- Slide out the old cabin filter and insert the new one with the airflow arrow pointing the correct way.
- For the engine filter, unclip the airbox lid, drop in the new panel filter, and re-clip the lid.

## The short version

The 2011–2019 Ford Explorer is the generation where the Explorer stopped being a truck and became a big, comfortable, front-drive crossover. It sold in huge numbers, so parts are cheap and everywhere, and it’s a genuinely pleasant family hauler. But two design decisions turn an ordinary used SUV into a potential money pit, and you need to know both before you hand over a check.

First: the V6 uses an **internal water pump driven by the timing chain**, tucked behind the front timing cover. When it wears out it leaks *inside* the engine, often with no puddle on the driveway, and in the worst case it pushes coolant into the oil, which can destroy the engine. Even the “easy” version is a 10–12 hour job.

Second: the AWD cars have a **Power Transfer Unit (PTU)** crammed against the transmission and exhaust. It holds less than a quart of so-called “lifetime” gear oil, the heat cooks that oil, nobody changes it, and the unit grinds itself apart.

## What that means when you’re shopping

If you don’t need all-wheel drive, a **front-wheel-drive** Explorer sidesteps the PTU entirely. That’s the lower-risk buy.

On any V6, the first thing to do is pull the oil cap and dipstick and look for a milky, coffee-with-cream film. That’s coolant in the oil, and it’s a walk-away. Then check for unexplained coolant loss, since the pump weeps internally.

On AWD cars, sniff for a hot, burnt gear-oil or “propane” smell after a drive and look for dark fluid on the passenger side near the back of the engine. That’s a dying PTU.

Two more checks are free and important: drive it from a rolling stop to feel for the known 6F50 hesitate-then-bump shift, and run the **VIN through NHTSA and a Ford dealer**. This generation has had multiple rear suspension toe-link recalls (a safety item that can cause loss of control) and the exhaust/carbon-monoxide-odor service action. A car with that paperwork already done is the one you want.

Everything else is ordinary used-SUV stuff: the door-ajar warning that won’t quit, an aging A/C, normal brakes and tires. The water pump and the PTU are the two things that decide whether you got a bargain or a project.

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.

Misleading

### [Is the "$1 Japanese oil trick" that stops engine wear forever real?](https://carcasefile.com/claims/1-dollar-japanese-oil-trick-mos2-engine-wear/)

The 'Japanese oil trick' is almost certainly MoS2 (molybdenum disulfide), a real industrial friction modifier. It is German, not Japanese (Liqui Moly popularized it), sold openly at every parts store for $15-20, has real but modest measured friction benefits, and was never buried by anyone.

## Frequently asked questions

### What are the worst years for the 2011–2019 Ford Explorer?

2011 is the first model year and has the most teething problems; 2013 logged the highest complaint volume of the generation; and 2016 is a peak year for transmission and exhaust-odor complaints. The later 2018–2019 cars are the more refined, lower-risk buys, but every year shares the water pump and (on AWD) PTU design issues, so condition and maintenance history matter more than the year alone.

### Is the Ford Explorer carbon monoxide problem real?

It was real enough to draw roughly 6,500 complaints and a years-long federal investigation covering 2011–2017 (and into 2018). NHTSA closed the probe without ordering a recall, finding CO levels below health standards in properly sealed vehicles, and Ford issued a service action to seal liftgate leaks and add fresh air via the HVAC. Test-drive with attention to any exhaust smell in the cabin, and check for the related service action by VIN.

### How much does the Explorer water pump cost to fix?

Because the V6's water pump is internal and driven by the timing chain, it's a 10–12 hour job, so expect roughly $1,500–$3,500 done at an independent shop. The bigger risk is if coolant has already mixed into the oil. That can mean an engine replacement at $5,000–$7,000, which can total an older Explorer. Check the oil for a milky film before you buy.

### Should I buy the AWD or front-wheel-drive Explorer?

FWD avoids the Power Transfer Unit entirely and is the lower-maintenance, lower-risk choice if you don't need AWD. If you want AWD, it can be reliable, but only if you treat the PTU fluid as a real ~30k-mile service item instead of the 'lifetime' fill Ford calls it. A neglected PTU is a common, expensive failure on this generation.
