2020 Jeep Gladiator

My Jeep Gladiator has recently been having multiple random error messages popping up. ABS warning, service 4WD, service shifter, traction control and others. Dealership charged $200 to diag a bad ABS module and charged $1400 to replace the module and controller. Less than 24 hrs later same issue occurred . Doing my own research this seems to be a common issue not just with Gladiators but other Jeeps as well. Many forums are saying it’s bad wire connectors or broken wires from improper initial installation. Causes issues with speed control, braking, and power steering.

The contact owns a 2020 Jeep Gladiator. The contact stated that while driving at approximately 40 MPH, the vehicle had suddenly started to vibrate and shake. The contact stated that the vehicle was maintaining its lane but was lurching from left to right. No warnings illuminated. The contact stated that she pulled off to the side of the road; however, when she turned the vehicle on, it would start shaking again. The contact stated that she would keep driving while the vehicle was shaking, and the shaking would eventually stop. The contact stated that the shaking was occurring at any speed and was also triggered when she would drive over any small bumps or dips in the road. The contact stated recently, while she was driving in traffic at approximately 10 MPH, the vehicle started to shake again, however, this time violently. The contact stated that at the time, it was raining. The contact stated that it felt like the vehicle had lifted up, and then she crashed into the guard rail on the driver's side front bumper. The contact stated that the bumper and an LED light bar attached to the front grill had made contact and were slightly damaged, and the driver's side headlight stopped functioning. The police were not called, and the contact was not injured. The contact reported that the driver's side front air bag had deployed but had not inflated and was draped on her lap. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed and was not repaired. The contact reported that after the crash, she observed the check oil and check brake warnings illuminated. The contact stated that she needed to depress the brake pedal with more force in order to stop. The manufacturer was not informed of the failure. The failure mileage was approximately 109,000.

During normal driving, dash would display multiple warning lights. There would be traction control, ABS inactive, and transmission errors displayed on the screen. Twice, there was a loss of power steering while driving. All signs pointed to a CAN buss issue, but dealer could not/ would not find it. Doing research, I found that the CAN buss connector located behind the glove compartment was known in the Jeep community to fail and cause these symptoms. The only replacement is offered by Mopar/Stellantis. Multiple models and makes under Stellantis company use this same connector that has bad solder connections inside. It causes increased resistance inside the connector, and causes CAN buss communication errors, and setting any one of hundreds of possible DTC. In every occasion, there was a loss of stability control, ABS, and multiple occasions of vehicle being locked in Park. In two occasions, the electric assist power steering was disabled.

While driving several warnings lights illuminate: traction control, ABS, air bad, service 4 wd, and brake. When this happens power steering is lost making it extremely hard to steer the car. The brakes are automatically engaged and occasionally the windshield wiper turns on. This causes a risk not only to myself and passengers but anyone driving near me as I can no longer steer with ease and the brakes lock up. My Gladiator has been at the Jeep dealer for 10 weeks while they try to solve the problem. They replaced the ABS module but that didn't solve the issue. I'm told that its electrical and whatever it is will harm several systems. My wife's 2018 Jeep Wrangler JL has the exact same issues. She has a very hard time controlling it due to no power steering.

I was driving at about 5 MPH and about to go onto the Freeway on ramp in Riverside, California, when the sensor in my car went off and locked the brakes, causing the person behind me to rear-end me. This is not the first time this has happened with this vehicle. Luckily, I was not injured, however, this could have been a serious injury if I was traveling at a higher speed or under many other circumstances.

My truck malfunctioned at an automatic car wash. It has approximately 54k miles. I had no warning lights or system alerts on vehicle or Uconnect app. I stopped in the parking lot & put the Gladiator in Park, I left the ignition on. I got off truck & got a towel to clean interior.There are several spaces to vacuum. I put the vehicle in DRIVE to move forward & out of the way of a patron that was going to reverse out. In DRIVE, I pushed the gas pedal in a slight & normal way. The truck REVERSED in DRIVE position. It accelerated to an unknown speed, it felt constant. I pushed break with foot I pushed D with. Right foot. The breaks didn’t work. I tried breaking several times during incident, it was approximately 10 seconds. I didn’t have time to use e- break. I don’t believe back up camera was displayed. I concentrated on physically looking at surroundings & steering. I avoided hitting 1 car, a SUV & a brick wall. The truck made contact with around 4 trees & a sign. The damage was mainly to L side. There’s damage to R side & R back tire had a bulge on it. I went over a concrete, grassy area & felt the impacts of front & back ends going over it & landing. I went over another concrete curve & hit a tree at an angle around the middle of front L cab. The impact caused the car to bounce forward. It didn’t move. I put the truck in Park from D position. I pushed off button. I couldn’t get out of truck of driver side door it’s damaged. 1 witness & lady from suv stopped to check on me. I called police to crash site. He noted witness & lack of break marks. Roadside service wait was long, officer called one. I made a report to Uconnect that evening. They gave me a case # told me they’d move vehicle to a dealer, inspect, analyze & call me. I’ve called, recorded calls & told case was elevated to higher level & no info can be given to me. They refused to tell me where car was, if inspected, warranty info, or what malfunctioned. My ribs, clavicles, r shoulder hurt for a month.
