Misfire on other Patriot years
Report counts are for each model year on its own, so a newer car has had less time to collect them.
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 (10 reports) and the catalytic converter (5 reports).
Recalls and investigations
No recall on the engine covers the 2015 model year as of Oct 2, 2026.

Is this a known problem?
The manufacturer has sent NHTSA 5 service bulletins or notices for the 2015 Jeep Patriot 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.

“Catalytic converter is bad. Check engine light is on. Other 2015 Patriots have a recall for catalytic converter recall but mine is not on that list. Should be.”

“Two issues- First one the vehicle engine tends to randomly sputter like there is a dead cylinder. Which I have found by adding electric jell to the spark plug connector will make the problem go away for a short time. Second one now in the rear transfer case is marking a grinding noise and is getting louder.”

Should you keep driving it?
This page can't tell you that. 0 of 29 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.
