2017 Jeep Wrangler: misfire or rough idle

Filed Apr 25, 2025 · Engine · NC

Vehicle had a DTC P0302 and a misfire at idle. Upon diagnosis cylinder #2 was found to have 80psi compression which is significantly lower than compression in all other cylinders. Cylinder head was found to be bad. This vehicle only has 61,303 miles. There are many owners complaining about the same problem and FCA indicated they fixed the head issues in 2013. They have offered an extended warranty for 2011-2013 vehicle but the issue still exists. The warranty should be expanded to include more year models.

Vehicle started leaking a substantial amount of oil. I took it to a mechanic to have it diagnosed, they stated that the engine oil cooler filter housing is made of plastic and over time warps and leaks. Apparently this is a major issue and has been noted on MANY dodge/jeep vehicles. Prior to this happening, the check engine light came on, I had it diagnosed and it showed as a cylinder 6 misfire. This could have caused major issues in the future if it had not been caught when it was including damage to the bearings and the cylinders (probably what is causing the misfire now).

This jeep has 60,000 miles and is 5 years old and has had all 4 calipers seized and rotators brakes replaced and cylinders misfired in the engine that has been replaced. All this on a new vehicle is insane and a safety hazard for a vehicle this young AND with this low of mileage. I took ownership of this jeep in March of 2020 with 33k miles. Then in January 2021 with about 40k miles on the car being 3 1/2 years old the back calipers seized causing smoke and burning smell and was a fire hazard and unsafe to drive. Fast forward another year and a few months later on May 13th I was driving the vehicle and the BACK calipers siezed while in operation and now both rear sides had to be replaced, rotators, calipers, brakes and hoses. A year and 1/2 later only 15,000 more miles. So now all 4 calipers siezed and were replaced, motors, brakes, hoses. This most recent time it was to the cost of $1427.15. I googled this issue and it is a common issue and a known issue in jeeps especially in 2017s. A complaint from 2017 shows a gentleman was reimbursed for this exact issue by FCA after his complaint and I am looking for the same. I have also had the engine cylinders misfire and go up in this jeep as well that occurred 2 months ago!
