Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“On 3 different occasions the acceleration got stuck and increased speed. I pressed the brake over and over and the Jeep would NOT reduce speed or slow down for what ranged between 30 - 45 seconds. Had there been a vehicle directly in front of me I would have slammed into the vehicle. If I had been trying to stop at an intersection I would not have been able to stop. I had my child in the car two out of the three times this has occurred. …”

“While towing a trailer the vehicle suddenly reduces power to less than half and multiple check engine lights appear. This seems to happen only when outside temperatures are above 80f. I went from going 65mph to 45mph within 1/4 mile which caused sudden traffic issues behind me. I have had the vehicle to the dealer multiple times and they do not find anything even though there are multiple engine lights. I have had it happen a over 8 times in 1 year. I also have a co-worker that has had the same issue.”

“Starting in August of 2022 I started getting error messages from the car about Electronic Stability Control, Antilock Brake Systems, and Collision Avoidance problems. These seemed to come and go. But if I was on the highway with Cruise Control on and these messages appeared the car immediately drops out of Cruise Control. In addition if it happened while braking the pedal would go almost to the floor and I would have to pump several times to get the brakes to work. I took this car to the dealership on 10/3/2022, 3/20/2023, and 5/20/2023. …”

“Vehicle will give you a warning to not shut off vehicle or you may not be able to put it back in drive, it automatically puts itself in park when coming to a stop at a stop light (without any door being opened). Automatically gives itself throttle when in Four Low. This vehicle has been in the shop more than I have had it since purchasing on 3/27/2021 for all of these electrical problems and whatever other problem it is that it has (I am unsure). It has never been fixed and is currently sitting at Freemont Motors in Cody WY waiting another attempt at repair.”

NHTSA complaint #11490661, filed 2022-10

“Vehicle derates power when ambient temps are 85* F and up while towing my camp (which is far below the max tow rating) During a couple of these derates I was in areas where the speed limit was 65 and 75 mph, my max obtainable speed was 35mph. I heavy truck traffic i feel that was in danger and a hazard in the road. This vehicle is rated to tow far more than the loads it is actually capable of towing in higher temperatures. I have seen my oil temps rise to 265* F on multiple occasions and it seems this is around the temperature that the vehicle starts to derate. …”
