Misfire on other Explorer years

Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2014, 2019, 2020, 2021, 2022, 2023, 2025, 2026.

What this problem usually is

These reports start with the check engine light. Many describe the engine running rough or shaking at idle, a P0300-series code, or a catalytic converter code. A worrying number say the light was flashing. Owners often list ignition coils or spark plugs already replaced, and the light coming back afterward.

What got replaced

Owners who name the part that was replaced mention the spark plugs (5 reports) and the ignition coils (4 reports).

Is this a known problem?

The manufacturer has sent NHTSA 12 service bulletins or notices for the 2018 Ford Explorer that deal with this problem. Newest first.

Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote

“Upon startup rough idle and check engine light came on. Mechanic confirmed cylinder head thinning causing fluid leak into first cylinder. A mechanical note verifies but Ford won't issue a recall. Apparently Ford has know this for years with Ecoboost engines. I don't want to become a victim of vehicle dying in the middle of traffic. Have seen several complaints from Ford owners with no fixes by Ford.”

Filed Feb 25, 2026

“Another timing chain failure on highway with engine stopping on road. This should be a recall!!!!! Only 101,300 miles on engine. No warnings no check engine lights until after failure.”

Filed Oct 22, 2025 · 101,300 miles

“My check engine light came on took the SUV to Ford Dealership for service. They informed me that my engine had coolant intrusion and that I would need a new engine. In reviewing this information online I noticed that there have been multiple recalls on the EcoBoost engine with the same problem.”

Filed Sep 27, 2024

“My 2.7L eco boost ford explorer had a crack in the intake manifold allowing water to leak into the piston heads. This resulted in engine misfire and ultimately led to a full engine replacement. The service technicians at the dealership noted that the 2.7 L eco boost are notorious for cracked engine components due to a mismatch in metal alloy. In reference to NHTSA# EA23002.”

Should you keep driving it?

This page can't tell you that. 1 of 29 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
