FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

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.

Fayetteville, PA

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

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.

Holbrook, NY

LANE DEPARTURE: BLIND SPOT DETECTION

The wire harness for the doors, which are designed to be removed easily, doesn't function properly causing pins to become bent when being reinsert. This causes several systems to malfunction and alert improperly. The blind Spot assist and cross rear warning is affected. This a common and known problem amongst Jeep owners who removed their doors.

BACK OVER PREVENTION

The contact owns a 2021 Jeep Gladiator. The contact stated that while driving at an undisclosed speed at night, he noticed that the headlights were obstructing the view of other drivers on the road, and that the drivers were flashing their headlights at him while swerving approaching the vehicle. The contact also stated that he had been pulled over due to the headlights. Additionally, the contact stated that while the vehicle was in reverse(R), the rearview image failed to display due to the reverse lights reflecting off the license plates and causing a white light glare. No warning lights were illuminated. The vehicle was taken to a local dealer however, the mechanics were unable to duplicate the failure and referred the contact to the manufacturer for assistance. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 2,000. The VIN was not available.

Arlington, VA Crash

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

While slowing to a stop and fully depressing only the brake with my right foot my vehicle rapidly accelerated into the back of another truck. It felt like the front brakes engaged, but the rear wheels continued to accelerate as the vehicle transmission worked to downshift. Serious safety issue-I am 100% confident that I was standing on the brake and not the accelerator. The road was dry with no gravel and I was gradually slowing to a stop when this occurred.

Cannon Beach, OR

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

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.

I when to the Dealer with big concern about could be something releared with the computer because they worked on it already and they told me no way could be the cumputer issues .A weeks after I took the car to the Dealer and in a week they fixed the problems without gave me a report about what they did , almost the same that happen in my 80 days before . Verbally at the Dealer they say was somting with the computer but that all what I got from them so far . NHTSA the reason Im filling this is because you can check the safety of the car when are new or even when they are been on the road for a while but Dealer doing what they are not supost to do bring accident to Our Cummunity as wells , We should stop those bad practices before become tragery . Thank You
