Reliability report · 2018 Ford Explorer · Updated July 2026

A quieter late-gen-5 year that still carries the water-pump and PTU risk — check the 3.5L before you buy.

The 2018 is a later fifth-generation Explorer, and the complaint volume drops sharply from the 2016-2017 years. But it is the same hardware, so the two patterns to price in are unchanged: the 3.5L V6's internal water pump (driven by the timing chain, seeps coolant into the oil) and the Power Transfer Unit oil leak on all-wheel-drive cars. Neither has open recall coverage — they are inspection-and-maintenance items.

The recall list is shorter here — a fuel-pressure-sensor leak that was a fire risk (18V-807), the rear toe-link fracture, and the A-pillar trim. On the plus side, 2.3L cars still fall inside Ford's transmission Customer Support Program window (20N07/20B27). A well-maintained 2018 with the water pump and PTU checked is a reasonable gen-5 buy; an untouched high-mileage V6 is where the money hides.

Canary status

Chirping

What that means: 705 federal complaints — well below the 2016-2017 peak, but the fifth generation's mechanical fingerprints are the same: the 3.5L V6's timing-chain-driven water pump and the leaking Power Transfer Unit on all-wheel-drive cars. Fewer recalls than the earlier years, but the ones that matter (fuel-pressure sensor, toe link) are still worth verifying.

3.5L V6 internal water pump — the gen-5 coolant risk carries over

major
  • 3.5L Ti-VCT V6

The 2018 shares the fifth generation's defining mechanical problem: the 3.5L V6's water pump is driven by the timing chain and sits behind the timing cover, so a slow internal leak sends coolant into the oil rather than onto the ground. Owners describe coolant that 'keeps going low with no visible leak,' traced by mechanics to the water pump seeping internally. Caught early it is a big but survivable job; missed, it damages the engine. Because the pump is behind the chain, the repair is labor-heavy — do the chain and guides while you are in there. Check for milky oil and unexplained coolant loss on any 3.5L.

This is a 3.5L Ti-VCT V6 problem. The 3.5L EcoBoost V6, 2.3L EcoBoost I4, 2.7L EcoBoost V6, and 3.0L EcoBoost V6 don’t share it.

Power Transfer Unit (PTU) oil leak on AWD carsmoderate

  • 3.5L Ti-VCT V6
  • 2.3L EcoBoost I4

All-wheel-drive 2018s carry the same PTU leak as the rest of the generation: the pinion seal weeps oil at modest mileage, the sealed-for-life fluid overheats, and the unit can fail — a job a shop mechanic says he has done 'over 20' times. The fix that heads it off is a fluid change every 15,000-20,000 miles with a fresh drain plug. Look underneath for oil around the PTU and ask about service history.

Fuel-pressure sensor leak — recall 18V-807moderate

  • 2.3L EcoBoost I4
  • 3.5L EcoBoost V6

A 2018-specific recall: on 2.3L and 3.5L GTDI cars an assembly error can let the fuel-pressure sensor leak fuel — a fire risk in the presence of an ignition source (recall 18V-807). The remedy is a free fuel-line-assembly replacement. This is exactly the kind of item that hides on a used car, so verify by VIN that 18V-807 was completed before you buy.

Transmission — reports thin, but the 2.3L program still appliesmoderate

  • 2.3L EcoBoost I4

Transmission complaints are lighter on the 2018 than on the 2016-2017 cars, but the gen-5 automatic's slip-and-shudder character is the same. On 2.3L cars, Ford's Customer Support Program 20N07/20B27 still extends transmission coverage and adds a torque-converter reflash. On a test drive, feel for harsh shifts or slip; on a 2.3L car ask whether the program work was done.

Toe-link and pillar-trim recalls, and the seat reclinermoderate

The 2018 carries the rear toe-link fracture recall (26V-101, the 2017-2019 expansion), the A-pillar trim-detachment recall (24V-031), and a seat-back recliner recall (19V-633) covering a missing recliner pawl that reduces seat-back strength. All are free repairs. On a salt-belt car especially, confirm the toe-link work; on any car, verify the recliner and A-pillar recalls.
