2021 Jeep Grand Cherokee: lane keeping assist jerks the wheel

Filed Mar 30, 2026 · Driver assistance · NJ · crash

My son’s car drifted to the right past the white line and he ended up hitting a hydrant and continued at least 100 ft before stopping. Our dash cam showed a slow smooth drift to the right without any lane assist being activated to pull the car back. All safety features were activated and turned on the day we bought the car for him. It was the main reason we chose this model. He is very lucky to be alive. After the impact, the car just barely missed a business sign, a telephone pole and a tree. The car was declared totaled. Unfortunately, the total amount the insurance is offering is about 4k short of what we still owe. Words cannot express how lucky we are that our son is okay, but we are very angry that the features we bought the car for, failed him.

When I started the car and backed out I was alerted that the power steering had a failure and lane departure warnings also. Power steering was not working. Left car for an hour and when I restarted it, warning light was off and steering worked again. Random power steering failure is extremely scary.

Backstory: This vehicle has had electrical issues since the day after signing the lease. The second day of driving the vehicle would not start and flashed all the sorts of engine failures. The dealership could not find anything wrong with it after two weeks and deemed it "repaired." Then, 2 days later the vehicle would not start again and flashed all sorts of of engine and system failures. After 4 months of going through FCA's process for the Lemon Law buyback, FCA presented a buyout offer that was inadequate and contained numerous release clauses we were not comfortable agreeing to. We choose to seek Mass Lemon Law State Arbitration as our right to ensure we achieved a fair outcome. FCA pulled our replacement vehicle and in essence forced us to drive to take back and drive the vehicle after it was again "repaired" this time by replacing a battery. The dealership that repaired the vehicle drove it for a week before we were comfortable taking it back. Incident: A month later, while driving the vehicle on a busy main road (at approx. 15 MPH), the vehicle started to alert that various systems were disable and the transmission started to shift violently and the engine reved. The ABS, airbags, lane departure, powering steering, and other systems said they were disabled and that the transmission was disabled. Fortunately, there was a parking lot on the right, I was able to turn into the lot, and attempt to find a safe place to stop. The parking lot was busy and before I was able to pull into a parking space, the car shut off and would not turn on. The hazard lights would not function, and the vehicle was blocking traffic and multiple parked cars. The car would occasionally start and stay on for 10 to 30 seconds at a time, but either the parking brake was locked or the transmission shifted violently as I pressed the gas pedal. After 20 minutes, I managed to limp the car to a safe spot and await a tow. The vehicle is at the dealership. There is also video.
