2024 Jeep Grand Cherokee L driver assist problems

FORWARD COLLISION AVOIDANCE: WARNINGS

This car slams the breaks to a stop in the middle of an intersection while turning left with other cars across the intersection also turning left. It thinks we will hit but we are not going to. This has happened twice. Luckily, the driver behind us was paying attention both times and also slammed their brakes, avoiding a collision.

LANE DEPARTURE: ASSIST

Active Lane Management disengages itself upon start up. Sometimes says needs servicing - message disappears upon car restarting. Car states key fob is not in vehicle when it is. Car has turned on, not shifted into gear, and then not been able to be turned off. Steering input from the system is sudden and does not consistently match actual road conditions Radio screen flashes/goes black/freezes Emergency Assisted Braking system activates without a clear obstacle present Braking events are abrupt and unexpected during normal driving Both systems operate intermittently and without a consistent pattern, making the behavior unreliable Dealership has been unsuccessful in reproducing any of these problems despite picture proof provided. Has happened on multiple occasions - beginning in September 2025. Jeep/Stellantis unwilling to resolve. Safety Risk: The unexpected steering corrections and sudden braking create a risk of loss of vehicle control and increase the likelihood of a rear-end collision or other traffic incident. These safety systems are not functioning as intended and instead introduce unpredictable and potentially dangerous vehicle behavior.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

I had my brakes flushed by my local dealer in June 2025 at about 31,000 miles for routine maintenance. I was traveling to York, Pa from Gravette, AR in September of 2025. All systems on my Cherokee had worked flawlessly on the trip, as they had since its purchase new in the Fall of 2023. On a very curvy, hilly road in the Cactocin mountain area, I was braking often. The ABS system warning light came on, as well as messages that the automatic collision control, lane departure control and adaptive cruise control were disabled. I noticed immediately that my brake pedal felt mushy and went nearly to the floor. Basically it felt like an old car with no power brakes. I proceeded to Gettysburg. When I restarted the car the error messages had cleared. I continued but after a few stops all of the error messages returned. When I got to York, still Thursday, I went to Stetler Jeep dealership and asked to have my Jeep looked at. The service clerk said no because I had no appointment. I asked to at least do an Obd2 scan so I know what the problem is. He said no, it can’t be done without an appointment. was told not until next Wednesday. I only planned to be in York until that Sunday. Between York and Decatur, IN on way home to Arkansas the warnings reoccured 3 more times, a total of 5. When stopped with my foot on the brake, when no errors showing, I would sometimes hear a clicking noise behind the steering wheel and feel it on my foot. A dealer in Indiana and my local dealer in Fayetteville, Arkansas could not find anything wrong. Those error messages have not appeared again without any repair. In December, my brakes were dragging and the brake waning light came on several times, then remained on. I could release the brakes by pumping them. My local dealer flushed brake system as the repair and warning light was gone. Two days later, brake system warning light is on again. I am taking it back to the dealer again even though brakes seem to be working fine.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

My 2024 Jeep Grand Cherokee was having failures with the Active Lane Management and Park Sense features not turning on. A visit to the service department revealed failures with both the front and rear facing cameras. While waiting for parts, I was travelling on the highway with the Adaptive Cruise Control enabled. (Not thinking about a possible bad interaction with the ACC.) In slowed traffic, my Jeep decelerated approaching a car, then suddenly accelerated. I had to quickly press the brake before crashing into the car in front of me. The Adaptive Cruise Contol should have disabled with the other systems have trouble with the cameras. The failure mode should have been to brake or shutdown, not to accelerate.

I have had this 2024 Grand Cherokee for barely 4 months and this is the second time I have gotten the notification “Automatic Emergency braking needs servicing” and “Right Lighting needs servicing” the AEB nor forward collision warning works and last time I brought it in they said the right head light was continuously running which is why it needed servicing and here I am 2 weeks later with the exact same issue.
