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.

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.
