Six problems related to check engine light on have been reported for the 2015 Jeep Patriot. The most recently reported issues are listed below.
The throttle body assembly was repaired in November of 2019. It is July of 2020, I have driven the vehicle less than 2500 miles since the initial repair and the vehicle is producing the exact same symptoms as it was before the repair. It hesitates, almost stalls, and lunges while driving. Traction control light, check engine light and the drive by wire warning light all flash when the vehicle is started and running.
Had issues with catalytic converters but was repaired prior to receiving the recall paperwork. My check engine light came on and this was the copy of the computer diagnostic. I paid out of pocket to get repaired.
Over the past month the throttle body control light, check engine light, and traction control light has come on when I go to accelerate. Just like others have reported, it comes on when I'm driving on the highway & just dies, you can't steer the car or anything. Or you go to accelerate and it dies & you almost get rear-ended. I cannot believe how many reports are on here similar to mine and there has been no recall although it looks like there was one for the 2016 Patriot. What will it take, someone dying? this is a huge safety issue when your car will just die while driving 65-70 mph & you can't steer or anything!.
As of 12/18/2018, my car has begun to die as I push on the accelerator after being at a complete stop at a stop light or stop sign, it even died out of no where, my husband was driving back home and thankfully there were no other cars behind him as he was passing the intersection when the car jerked and decided to turn of completely. He put it on park and started up like normal but no check engine light came on or anything. Ever since I got this car in February of 2016, take note that my Jeep only has 65000 miles and I have never had any problems with it until now. It is terrifying because each time it has happened, cars behind me were very close to rear ending my car. This is a big and scary issue for me because I have read on numerous websites that their Jeep Patriots have died on the highway. . . I have a 3 month old that I take back and forth to a baby sitter every weekday, and that is a huge safety issue for my daughter and for people driving around me as well. I have read on a numerous amounts of websites where other Jeep Patriot owners are having the exact same issue. I keep my oil changes up to date and I just changed my spark plugs. So I have no clue what the problem might be I have not taken it to have it checked because of what I have read I see that others have not had luck with taken it to a shop I would hate for this issue to cause somebody to rear end me on the streets or on the highway. Either being on the streets or the highway, it could cause serious damage and injury to me, my 3 month old daughter and to the people around me. Hopefully they have a recall soon!.
Vehicle hesitates while accelerating on flat or inclined ground. The electronic throttle control (etc) indicator light will come during the hesitation and go off when power resumes. See attached photo for reference. On more than one occasion the red light has come on and the car has gone into limp mode. When this happens the traction an check engine light will come on. The car can be turned off and back on and this occasionally clears it. At times an obd-ii computer must be used to clear the codes and then resume driving. This has happened sporadically since 2018.
Air bag cover rattles over 45 mph has been doing this since mileage of about 1000 check engine light comes on with code p0128 faulty thermostat 2 times in the last month pulls to left over 60 mph has been doing this since June has been back to dealership 2x.
