2023 Jeep Grand Cherokee forward collision avoidance problems

“As I was driving the warning system alerting me to BRAKE! came on and jerked the vehicle to a stop even though no one was in front of me and there were no cars next to me either. Extremely dangerous to have the vehicle stop out of the blue while driving 20 mph. The component has not been inspected yet and the warning lights came on the dashboard.”

“Vehicle previously brought to dealership for recall and reported issue where vehicle abruptly stops/brakes without cause. Dealer did not resolve. On 3/16/26 vehicle came to a complete stop in roadway, shifted into park, and could not be moved into drive, neutral, or reverse. Driver was stranded in a dangerous situation with infant in vehicle. Dealer unable to inspect for weeks and refused loaner. This presents a serious safety hazard.”

“Since shortly after taking delivery of my 2023 Jeep Grand Cherokee 4xe, I have repeatedly experienced intermittent safety-related malfunctions involving sudden steering stiffness and braking intervention. From early in ownership, the vehicle would unexpectedly engage what I later learned is the Automatic Emergency Braking (AEB) system. During these events, the steering would feel locked or restricted and the brakes would apply without driver input. In order to restore normal operation, I was required to pull over, turn the vehicle off, and restart it. These concerns were reported multiple times to the dealership over the course of ownership. On January 13, 2026, while traveling at approximately 60 mph on the highway in normal traffic conditions, the vehicle suddenly lost propulsion without warning. At that time, the instrument cluster displayed a “HYBRID / ELECTRIC MODE UNAVAILABLE” message along with a wrench indicator light. The vehicle immediately began losing power and was unable to maintain highway speed. As the vehicle slowed unexpectedly in active traffic, two tractor-trailers were approaching from behind. The sudden loss of propulsion created an…”

“I was driving down the interstate with my two babies in the car seats and all of a sudden all of the dash lights came on, and the power steering locked up. I was driving 70 miles per hour and had to pry my wheel as hard as i could to be able to pull over on the side of the interstate. Once I pulled over i turned the car off hoping it would reset whatever happened and the car was completely dead. It would not crank at all. I ended up having to call someone to come get me and my kids off the side of the interstate and tow the car to the dealership. this car has less than 70,000 miles on it and still is not fixed. It has been at the dealership for over 3 weeks with what they are telling me is electrical issues. I do not feel comfortable driving this car anymore as it is a safety hazard and could have gotten me and my children killed.”

“Forward collision warning. While attempting to make a left hand turn with a green arrow onto a busy highway, the car suddenly slammed to a stop almost causing a collision. The problem has not been reproduced as it hasn’t been driven again. It is not yet at the dealership. The vehicle has not been inspected. No warning lights prior to the problem.”

“Vehicle Purchased 05/27/2025 6/6/2025 - 9 days after purchasing the vehicle i was left stranded in the parking lot due to the battery issues. The vehicle showed a warning stating to "Service Charging System" and the entire system locked out and the vehicle was towed to to the dealer for evaluation and was there for over a week. When I received the car back they stated it was just the battery and not the charging system/hybrid system. 12/03/25 - While driving on the freeway, warning lights started coming up and the seat belt bell started going off even though everyone was buckled. Then my power steering was disabled, the ABS system was disabled and the breaks stiffened, lane assist was disabled, the airbags were disabled, and the SOS calling, and the engine shut off. When trying to change lanes we had to use extreme force to turn the wheel and the emergency lights wouldn't engage when the button was pressed. Due to the brakes being stiff beyond reason it took us passing 3 freeway exits to slow down enough to force the car off of the road. I had my children in the car and was terrified i was going to be in a crash or worse, lose control and veer off of the road.…”
