Misfire on other Wrangler 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: 2016, 2017, 2020, 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 sensor (8 reports), the injectors (4 reports) and the ignition coils (3 reports).
Recalls and investigations
No recall on the engine covers the 2014 model year as of Oct 2, 2026.

Is this a known problem?
The manufacturer has sent NHTSA 5 service bulletins or notices for the 2014 Jeep Wrangler 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
“3.6l Pentastar V6, vehicle had a failed oil cooler housing. This caused the vehicle to leak a considerable amount (more than a quart) of oil into the valley between the cylinder heads, but showed no outward signs of leaking oil. This has the potential to ignite a vehicle fire during operation. Could also potentially cause catastrophic engine failure secondary to oil starvation at highway speeds.”

Should you keep driving it?
This page can't tell you that. 0 of 26 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.
