ENGINE

When I attempted to turn left onto the highway from a complete stop on an incline, I pressed the accelerator and the car made a loud grinding noise. The vehicle would not move forward or reverse. The parking brake engaged on its own and would not disengage. After exiting the vehicle, I found a loose bearing behind the car. The vehicle had to be towed to a mechanic. I was informed by the mechanic that the failure was caused by the PTU (Power Transfer Unit), and the repair cost me $2,600. I was later told that the initial failure had also stripped another component, which required an additional $100 repair. I was not given the specific name or details of that additional part.

ENGINE

In November 2024, while driving, my jeep began to lose power. Accelerator was not working and pulled over. It turned on but would unexpectedly turn off whenever I would drive it. It was in the shop 4 months. Last week, Nov 2025, while at a stop light it completely stopped working. When I tried to accelerate it wasn’t working. Break pedal was hard and I could not turn it back on. Dash lights were on and tank had gas. Had to get it towed. Was told engine was in good shape. Still looking at starter issues.

ENGINE

My 2020 Jeep Cherokee was in for a multi-point inspection and oil change on 9/10/2025. On 10/15/2025, the Service 4wd, AWD System Service Required light turned on as I was driving. I called the same dealership immediately and was able to get it in for diagnosis on 10/21/2025 (the soonest appointment available). They called me on 10/27/2025 to inform me that they diagnosed a faulty PTU part #68333254AI. They sent me a quote of $3,129.81 for the part, labor, and fluid. My Jeep has remained at the dealership since it was diagnosed. I was told that there could be a loss of power to the wheels that could result in loss of control and a potential crash. I was also told that it may be an extended period of time before they can get the part. The dealership has stated that this would not be covered under my warranty because the warranty ended on 10/17/2025. The warning light actually came on before this date. I understand that there was safety recall/class action lawsuit for this issue on the 2017-2019 years but not the 2020. I feel that this is a known safety issue and believe that it should be covered by my warranty or the manufacturer. My vehicle's mileage is 43,230 miles.

The contact owns a 2020 Jeep Cherokee. The contact stated that the parking brake engaged independently while idling at a stoplight.

ENGINE

My Jeep keeps going into Limp Mode and not will completely shut off while I come to a complete stop at a stop light. And while I’m driving the engine light comes on. I can cycle it through to get the engine light off. Then it runs fine. This has been happening since after I bought it. I’ve taken back to the dealership I got it from and they couldn’t find anything wrong with it, so they took it to a Jeep dealership and got the same answer. Clearly there is something wrong with it. And could cause me to get into an accident. This is my only vehicle for transportation. The code that shows up is P0934

ENGINE

The message/warning light keeps coming on: Stop/start Unavailable - Service stop/start system. This feature is suppose to help reduce the amount of harmful emissions released into the air! Some times this causes the engine/transmission to clunk. Seems to maybe a common issue with the Jeeps. Save fuel from burning while the car is stationary. Such a great feature and is doesn't work!

ENGINE

The engine light comes on randomly. And causes the transmission to bog down and unable to accelerate. We have to pull over and shut the vehicle off and cycle it a few times to get the engine light to come off and then it drives fine. Has happened multiple times and has happened on the highway while driving. I’ve also had the vehicle completely shut off while driving. I’ve taken it to 2 dealerships and was told there is nothing wrong with it. I’m afraid it will cause a bad accident and I’m gonna get hurt if this issue isn’t resolved soon. The Dealership I bought it from Tim Witt Chevrolet in Crivitz Wi. And they took it to Riverside Jeep Dealership in Marinette Wi.

ENGINE

I was driving down the road when all of a sudden I felt a loss of power, and it started smoking. Turned out that the oil filter housing was made out of plastic, and had broken, the car was only ever taken to the Jeep dealership for service as it was purchased certified pre owned, and it was replaced with an aluminum part instead of this plastic piece. They replaced the oil filter housing and the valve cover gasket with less than 40,000 miles on the clock. Thankfully I was on my way home, but if I would've kept driving, it would've resulted in a fire or accident.

ENGINE

Vehicle popped an engine as the vehicle was in motion. After taking it to a mechanic, they ran diagnostics and said that the Active Grill Shudder (AGS) had stopped responding to the cars computer. The problematic part was ~$600 and happened 11 months after purchasing the car. The dealer refused a reimbursement stating that they couldn’t help as I brought it to a local mechanic. The fact the engine light popped up while the car was in motion could be a safety issue. No warning happened before the issue presented itself. The car started fine with no engine light.

INITIAL CHRYSLER CUSTOMER CARE CASE #[XXX] NEW (ESCALATED TO SUPERVIOR) CHRYSLER CUSTOMER CARE #new case #[XXX] high idle new engine at about 50k miles when car was 3 years old new battery $270 recently SVC 4WD - in July dealer told me it wasn't covered under warranty and made no mentioned of goodwill warranty, 2-year grace on warranty, nor any options. several mechanics told me $3K to fix. declined. called dealer who told me to call Chrysler customer care who told me they can't do anything until dealer diagnoses the vehicle. Chrysler customer care tried various times to reach service team at sterling heights dodge - they would not take call or call him back. he finally reached someone who told him that i need to come by and they can look at my car and then after I could see receptionist to then make appt. he said it doesn't make sense for me to go there twice. I did call and make appt and have gotten the run around since. Chrysler customer care told me I would qualify to have this fully covered since I was just over warranty (now at 65K miles since months has passed since this first occurred in July (60,250 miles) and because I was the original owner and mentioned something about a 2-year grace. However, the goodwill warranty came back only covering 70% and making me responsible for 30%. This is ridiculous - this is just a start or continuation of more costly major repairs, and I cannot afford to keep this car any longer but need to get this fixed so I can trade it in or sell it and get a new car with a different automaker. I cannot get Chrysler customer care to call me back nor is the dealership willing to help. While I don't know the ins/outs of lemon law and this probably doesn't qualify, it feels s like a lemon. see attached letter for details/history.

ENGINE

The vehicles emergency brake engaged while driving down the highway at 70 mph on its own. This caused the vehicle to come to an immediate stop almost causing a serious wreck. We have had the vehicle in the shop for it dying and this happening when stopped or at very sloe speeds but never like this. Each time we have been told there is nothing wrong with the vehicle since no codes were thrown. Clearly this is not the case.

ENGINE

Our Jeep has had multiple accounts of shifting hard, hesitation while shifting, and a on and off service 4wd light. We reported these issues to the Jeep dealership it was purchased from and they said nothing was wrong after 4 scheduled maintenance visits. We brought our Jeep to a neighboring dealership who immediately found the issue and said it was a major transmission component that went bad. Fast forward to a week later and the part has been fixed but the issue is still happening!

When coasting at low speeds the vehicle makes multiple click sounds and now there has been a clunking sound seems like when. Trying to downshift or upshift almost as it can't find a gear. When in a stoped position I put it in drive ease the gas and it will jump into gear. Has been multiple complaints about clicking and clinking with the vehicle and nothing fixing the problem unless ptu,transmission,u joint or driveshaft is replaced this is scary to spend so much on a vehicle for my family and worry about when it's going to break down.
