Driving a 2021 Jeep Cherokee Trailhawk on the interstate with cruise control engaged. All of a sudden the vehicle decelerates/downshifts and the display screen flashes "4WD System Unavailable Service Required" and "4WD Neutral Warning". Trying to cross traffic to get to the shoulder of road and almost hit due to deceleration. Press gas pedal and nothing. Traction control light flashes on. Coast cross traffic to shoulder side of the road. Shut off Jeep. Check for loss of fluids and/or parts. Check brakes. Nothing. No smoke. No burning smell. Turn vehicle on. Vehicle automatically engages parking brake. Shift off parking brake and shift vehicle into drive and it makes a grinding noise like its trying to shift into 4WD. Snow mode pops on as well as the FWD Collision light and traction control. Jeep ran just fine until this point and no prior incidents, no bad/hard shifting. NOTHING.

Car completely died while operating. No Power. Dead in middle of the road. Unable to signal other cars. Jeep dealership ran code and replaced battery. Did not check PTU as requested. Car is now acting up similar to PTU issues. Exact same experiences as outlined in the recall for 2017 to 2020. 2021 should be included for this recall and reviewed or repaired as this is a known issue in jeep cheerokes. This is a serious issue due to the fact that they shut down immediately leaving you in the middle of the road with zero ability to notify anyone you are stopped. No warning signs were present.

The vehicle gave us a service 4wd warning on my wife's way home from work. The car had numerous issues driving it home. It wouldn't move in drive, until it was put in park and then back into drive and it would automatically engage the parking brake. Once she brought it home I went to check the vehicle. I got into the vehicle, put it into reverse and backed up the driveway. Once I stopped and placed the vehicle in drive it automatically engaged the parking brake. I put the vehicle in drive disengaged the brake pulled the car forward toward my house. I stopped the car placed it in park. The vehicle kept rolling about 2 ft. Into my garage door and then engaged the parking brake.. I don't know what is wrong, I have never seen a vehicle do this. I have checked and this is a common problem. I don't know why this isn't recalled. It is a dangerous vehicle like this.

Bought used for my daughter in Jan 2023. Car had 30,290miles. The parking brake has been coming on while she-??s driving. She is also getting a forward collision service message, as well as Lane assist service message. It-??s gonna cost us $1K to repair. I hope this takes care of the problem. I don-??t like my daughter driving a fairly new car with so many issues. The parking brake issue is very discomforting. Also the stop/start function is not working. The mechanic says a new battery will resolve this issue.

The emergency brake activated when I step on the gas at a light. It would disengage until I turned the car off and back on. It was raining during the time. When I called the dealership(Darcars dodge and Jeep, Temple Hills, Ms) they claimed they-??d never heard of these incidents happening.

I put my car in tow mode, after hooking up my RV, followed all proper procedures, after I turned key off and closed the door, between then and when I started to roll, the emergency brake AUTOMATICALLY ENGAGED! I burned up my two rear Jeep tires and could have been worse had not a nice guy stop me and said your tires are on fire!!! I have a 38 ft Alpine, so didn't realize the pull! I luckily only had to replace my 2 rear tires and one sensor that melted! $450. Since then I watch for this DANGEROUS AUTO FEATURE and it has engaged on its own again a few times, not always, but occasionally. I can't have this going on it I plan to tow this vehicle!

While putting on new tire valve caps, I noticed a drip of something wet on the inside of one of the rims. It smelled like brake fluid. I took the car to the dealership for inspection. I was told that I couldn't drive the car, that the caliper was leaking brake fluid, and that it would take about 6 days to order and replace the caliper. If gone undetected, the defective leaking caliper could have resulted in brake failure. There was no warning lamp to indicate an issue.

We were in a front impact vehicle accident. Airbags didn't deploy, brakes failed after impact and the engine didn't shut down. I had to disconnect the ECU power relay for the engine to stop.
