Report from diagnostic service 1-9-2023 cylinder head - has premature failure of valve guides and cylinder head replacement is required for repair. Yes, Jeep extended the warranty but if your vehicle did not show problems they would not fix it, but they did learn and knew at the point the seriousness of the problem and put an end date on the fix. Our vehicle outlasted their warranty by 30,000 but now is undrivable. Before anything serious happens as the driver drives on longer drives we have grounded the vehicle.

Engine Stalls Randomly while Driving. Will crank over several times and over approx 10-15 min. of cranking(Say every 3-5min) vehicle will and will restart. No check engine lights and no warning. The loss of power can be dangerous since brake and steering assist require engine to be running. Vehicle will be fine for several days local commute and problem will recur without warning, usually on longer commute. Vehicle is unsafe and unpredictable.

The vehicle would take a minute to click into gear when at a light and also when driving on the freeway, the vehicle will only go up to a certain speed (40mph) and would not switch gears (automatic) after that, the RPMs just kept going higher until I had to pull over.

The power steering line has rubbed a hole in the transmission line causing a loss of flammable transmission fluid onto the hot exhaust and underside of vehicle and the transmission isn't shifting properly. Transmission fluid could ignite on the hot exhaust setting the jeep on fire while driving. The dealer refused to work on my jeep because of some modifications that do not affect the Transmission lines or power steering lines in any way to cause this issue. No warning lights came on, I had noticed the lines rubbing about a month and a half prior which is when the dealer said there's nothing they can do they didn't even look at it.

My Jeep is now stalling mid drive when I turn my wheel. 3 times it's happened while turning from a stop light and oncoming traffic had to stop and go around me. I've had 2 mechanics look at it and neither of them can find an issue. Rpms go to zero and my steering wheel locks up. The only way to reset it is to put it in park, turn the car off then back on. Outside of those 3 times it's happened while the vehicle is running and turning onto a street or into a parking lot - there is no rhyme or reason to what will trigger it. I've read quite a few forums where this seems to be an issue. This is a huge safety issue and needs to be looked into immediately!! I went from feeling carefree in my Jeep to keeping both of my hands on the wheel while making any turn and being constantly tense. Please please announce a recall and fix this!

Engineering defect I had to replace the oil pan on the transmission I found that the condensate from the air condition was draining on top of the transmission and running down to the corner of the oil pan and rotting the pan out. Will send pictures I sent this complaint in before but did not hear from you.

My Jeep Wrangler is in the dealer today the car has 29,000 miles the transmission drain pan is leaking they claim it is from rust the pan may be white metal or aluminum I asked the parts person at the dealer earlier if they sold a lot of pans he said yes I checked the forum other people with the same year and low mileage have the same problem I feel the pans may be the wrong material for the oil being used. And may need a recall on the pans.

Oil housing cracked during routine oil change, due to an integral part being plastic. Any oil change could result in an instant $600-$1,000 expense for the consumer. It impossible for the consumer to prove the broken part was due to oil change negligence or over-tightening. The cost is entirely left on the consumer even if all preventative maintenance work is complete. This has to be a known issue at Fiat Chrysler/Jeep, and must be addressed by a recall. I replaced the part, for approximately $600, with the same part. This could easily happen again at my next oil change, and every oil change thereafter. I should not have to guess if there will be a $600 repair every time I change my oil.
