2021 Jeep Cherokee Forward collision avoidance Problems

“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.”

“I am reporting a safety concern involving the Forward Collision Warning (FCW) system on my 2021 Jeep Cherokee Altitude FWD with a 2.4L engine. Every time I start the vehicle, the dashboard displays the warning message FCW Unavailable – Service Required.

“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 purchased this 2021 Jeep Cherokee, and it has developed a life-threatening defect where it performs an uncommanded braking while driving at speed. Without any warning the car slams on the brakes creating an immediate risk of a Rear end collision. Diagnostic scans show multiple critical failures: PO128 (the initial warning of a computer communication issues). …”
