Cold start, engage reverse and the engine idles really low and sometimes stalls. If I move the shifter to neutral the engine revs back up and does not stall. Rolling down the driveway and then engage reverse the problem does not occur. The issue has been getting worse whether its in the dead of winter or summer.

Torque Convertor is going bad. On a cold start, when you put Jeep in reverse, it will stall. This started around 50k miles. At first, I thought I did something wrong. Then it started happening more often. I contacted Jeep, but they said they could not do anything because the Powertrain warranty was expired by a couple thousand miles. This is dangerous when I have to back out of my driveway in the morning as it will stall and can take a few times for it to restart. There has been no warning lights or codes that pull up on my OBD2 scanner that would lead me to knowing what the issue is.

Torque Converter was replaced due to internal failure. Vehicle had 62k miles when torque converter was replaced. Issue arouse around 40k when vehicle would die when placed in reverse after cold start. AutoNation dealership did not cover cost since vehicle had went over 2k of the power train warranty. When I researched online, I came to realize that this is a common problem within the JK models which is upsetting to pay out of pocket cost for defect parts from the manufacturer.

When transmission is cold and is put in reverse it will cause loss of control and stalling of the vehicle. When restarted the vehicle will run with a very rough low RPM idle, has happened many times over last few months. Will document from now on when it does it again.

Typically on first start of the day in cold weather (sub 40degrees) with foot on the brake while in putting the Jeep into reverse causes it to lurch backwards, drop idle and then stall while in gear.

- Logan Township, NJ, USA

On cold days after the Jeep has been sitting overnight, the engine will stall when the transmission is shifted into drive or reverse. This happens when the Jeep is started and it makes no difference if the car is running for 30 seconds before it is shifted or running for 3 minutes, the engine will stall when shifting into drive or reverse. This happened last winter and has started doing it again now that its cold.

I have gone through over 4 sets of mud terrain tires over the last two years that are unevenly worn and no one knew why. Most recently, the rear right tire had a sidewall gash and had a flat tire, we began smelling smoke and ended up taking the Jeep into brakemasters and was told the entire rear differential was failing and falling apart. We had the rear diff replaced, brakes, rotors and paid $5000 out of pocket and as I was driving from home to tucson the other day to my maternity appointment, the back right tire began screeching while not braking and began sizzling and burning with oil coming out from the tire. I immediately stopped at the nearest brakemasters and they said that an entirely new rear differential is needed. Not only could the Jeep have caught on fire with this safety issue but I kept losing control of the steering in the middle of the city with a 2 year old and one on the way. I am hoping to see some sort of resolution on this and to be communicated with other Jeep owners of this safety issue.

The oil filter housing assembly is made of plastic that cracks. This leads to oil leaking and several inches of oil sits in the V of the hot engine until it spills over. This is a definite fire hazard. Fca needs to recall with a redesigned part made of metal. I have already replaced mine twice in 1 yr. Replacing it with the same part is not fixing it. Failed at 29K miles and now at 42K miles. This is a $1000 repair each time. Mine was covered under power train warranty but this is unacceptable quality and practices. I noticed oil leaking underneath the engine again and this time I thought it was the rear main seal. I noticed burnt oil in the V of the engine block as well. To my suprise, same part has failed already. Parts failing at this low of mileage are a design flaw that is being ignored by fca. Something needs to be done. Oh... one last thing..while the mechanic had it apart, he noticed the head gasket was leaking too so he replaced that at 29K miles. No wonder Chrysler/Fiat is the worst car maker in the world.

Randomly driving on the road at various speeds this Jeep will suddenly unexpectedly begin to shake violently and causes the driver to be unable to safely control the vehicle. Jeep dealership does not guarantee it can fix the problem but is aware of the problem. Other mechanics are aware of the problem and are unable to fix it. This has happened multiple times at multiple speeds on the city streets and at high speeds on the highway. It happens when driving straight and it also happens when turning. This vehicle has not been repaired or involved in an accident yet but it is unsafe to drive

My wife has had her gas pedal stick on her on three separate occasions, and I have had it stick on me once (10-4-20). The first time it did it to her was about a month or so ago, and then it did it to her twice this morning on her way to work (10-9-20). It seems to only do it under a hard acceleration. The pedal will drop to the floor, RPM will shoot up, and it will not disengage for a good 10 seconds or so. I have verified that the floor matt is not obstructing the path of the pedal. This seem sto be a common problem among the jk Jeep, but nothing has been done about it.

A common number 4 cylinder misfire that seems to common on all Jeep forums. The code was found to be a no compression in the cylinder. Although so many people complain of this issue, Jeep doesn't do anything about this? my engine is 4 years old and I'm being told I need a new engine and it's no longer under warranty.
