2021 Jeep Gladiator: adaptive cruise control problems

Filed Jul 11, 2026 · Driver assistance, Fuel system · NC

The vehicle was bought in CA and hasn't had any issues till about after 3-4 yrs later. 1) Adaptive cruise control / emergency braking system / forward collision notification will occassionally state "not availble/unavailable" or "visibility" is not available and to clean windshield, but the windshield is not dirty or obstructing the camera. 2) The fuel emission system has had several diagnostic codes referring to the gas gap or fuel sensors. Vehicle is boggs down/loses power and starts ideling roughly and acts like it wants to shutdown and has shutdown. I've had to get vehicle towed twice for this issue. Replaced gas gap and still had issues. Then they went away for a few months, but now I am getting a diagnotic code stating that the fuel tank gas sensor is causing the check engine light.

On [XXX] at approximately [XXX] I was travelling West on [XXX] , between Hamlin and Kimballton, Iowa. I had been driving with my cruise control set at 60MPH, until I caught up to an 18 wheel livestock semi truck. The semi was travelling near 40MPH due to curves in the road in this area. With no traffic coming from the West and an acceptable stretch of passing zone, I decided to pass the semi. As I entered the Eastbound lane to begin my pass, I pressed the accelerator pedal all the way to the floor and accelerated past the semi. As I was completing the pass, the road began to curve to the left, which naturally caused the Jeep to re-enter the Westbound lane, which is what was expected and is what I wanted to do, as I was well clear of the semi. What startled me, actually scared me to death, is when I attempted to steer to the left in order to remain centered in the Westbound lane. When I attempted to steer, the steering wheel seemed to be locked in the straight forward position. I grabbed the steering wheel with both hands and it took pretty much all I had to force the steering wheel to turn left at all. I had to have come within inches of dropping off the shoulder on the right (North) side of the road, while still in the left curve. The steering remained very "tight" and very hard to move much outside of the centered position. I continued driving as there was very little traffic. Upon reaching the town of Harlan, IA I had planned to stop and access the situation. However, when the vehicle speed slowed to somewhere around 30MPH, the steering system corrected itself and began to function normally. I continued to my destination in Omaha, NE without further issue. To say that this event scared me is an understatement. It could not have happened at a worse time and I believe I was within inches of exiting the roadway due to the inability to control the vehicle. I am certain that if my wife or kids had been driving, a crash would have INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FO

This vehicle has a repeating electronic problem involving the warning lights and function of abs, traction control, four-wheel drive system, forward collision warning, and both adaptive and normal cruise control. When the steering wheel is turned slightly right, like when navigating a highway curve, those warnings illuminate and the vehicle disables cruise control. It also has a lack of power due to what seems to be the traction control system activating. Also, the brake system has a shutter in the pedal and has reduced effectiveness for a few moments until the ABS and traction control systems stop function. I have taken the vehicle into a dealer, Larry H Miller CDJR in West Bountiful, Utah when it started to show this problem as I was leaving Portland. They replaced the front left ABS wheel speed sensor. This did not rectify the problem. I then took it to Gene's Chrysler in Fairbanks, Alaska upon my return home. That shop failed to warranty the repair, and charged additional diagnosis fees on top of correcting the Z96 high pressure fuel pump recall. They advised replacing the clock spring in the steering wheel that provides electrical connection to the buttons and is integrated in all of those safety systems. Prior Jeep models have had a consistent problem with the clock spring failing and a recall was issued due to affecting airbag deployment from the steering wheel. I am concerned that this clock spring related issue may lead to reduced braking effectiveness, loss of power at speed to react to traffic, and failure to deploy the airbag in an accident. The dealerships will not warranty this repair.

It got 7 problem issues and almost lost control due to electronic throttle control failed while drove on freeway and tow teardrop (1400 lbs) . Malfunction indicator light, traction on (could not turn off), electronic stability control active popped up ( could not turn off), service forward collision warning light, cruise control fault warning light, service stop/start system warning light, service adaptive cruise control warniing light (all of them popped up that could not turn off).

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. In the first 2 instances I was told the part would be available within 6 weeks. For the last instance I was told the part would be in in 2 weeks. That was over 6 weeks ago and still Jeep has been unable to provide the part. Being unable to provide a part so key to many safety systems represents a significant safety concern.

While ACC deactivated but not turned off (in "cancelled state", where you can resume with a button), I was at a Drive-Thru ordering my food, when I finished ordering I slowly lift my foot of the brake then suddenly the car lunged forward as if it was going to catch up to set cruise control speed, fortunately I braked immediately otherwise I could have crashed into the car in front of me. Another incident happened on my driveway, I stopped on my driveway to open the garage door, when I lifted my foot of the brake, the car lunged forward. (Same as before, ACC deactivated but not turned off). It is very scary and worrisome, I am worried that it will happen again and I won't be so lucky then.
