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 ignition coils (9 reports), the spark plugs (8 reports), the sensor (5 reports) and the catalytic converter (3 reports).
Recalls and investigations

The engine block heater may crack and develop a coolant leak, causing it to short circuit when the block heater is plugged in.
Improperly brazed turbocharger oil supply tubes may leak oil on engine components.

Is this a known problem?
The manufacturer has sent NHTSA 10 service bulletins or notices for the 2017 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
“Driving down the highway and checkengine light came on when I was headed to work. The vehicle lost power due to misfire with engine. I check the spark plugs and there is oil all over sparkplugs and the coil packs. This is a serious issue and needs to be addressed by ford immediately, they need to put a new engine in or pay me to get this fixed.”

Should you keep driving it?
This page can't tell you that. 0 of 59 reports involved a crash. 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.
