Jeep Gladiator abs comes on

Filed Jun 15, 2026 · Electrical, Steering · FL

The vehicle suffered a catastrophic, systemic high-speed CAN C data bus loop collapse (Diagnostic Trouble Code U0002-00 "Bus Off"), resulting in an immediate, total loss of communication across almost all primary factory control modules—including the Body Control Module (BCM), Powertrain Control Module (PCM), Transmission Control Module (TCM), and ABS gateway. The vehicle is completely immobilized. This specific network data loop shares an exact architectural footprint and physical circuit link with the high-current electrical defects targeted under active, open Federal Safety Recall Campaign 21D (the federal safety agency Campaign 21V‑363) for this VIN. The franchise dealership (Jacksonville CJDR) is actively using cosmetic visual framing of secondary aftermarket accessories to avoid executing baseline electrical isolation of this factory defect. Furthermore, the facility is demanding a predatory, upfront out-of-pocket retail diagnostic fee of $1,188.15 "to start" before they will address the network crash. This extortionate pricing barrier is being used to actively block a consumer from accessing a mandatory federal safety campaign remedy on a compromised, high-risk circuit. Official factory wiTECH 2 diagnostic screenshots confirming the complete vehicle network blackout are attached to this file.

This vehicle suffered a sudden; catastrophic hydraulic brake fluid leak and complete system failure shortly after a service visit with only 700 miles total on the new vehicle. Hours prior to the failure, Lindsay Chrysler Dodge Jeep Ram of Manassas, VA (where the vehicle was purchased new, earlier that month) performed and signed off on a multi-point inspection as fully functional while the vehicle was taken in for other warranty service (non safety or brake related). As a former mechanic, I inspected the vehicle immediately when I arrived home on the same day and discovered the brake fluid reservoir was almost half empty with fluid actively leaking and pooling on the frame and around the inner fender! Due to the catastrophic safety risk, the vehicle was immediately towed to Safford Jeep of Fredericksburg, VA to due it being geographically closer to my home, confirming the safety failure, and fixing the following defective components: Brake Hydraulic Control Unit and ABS Module. Lindsay Chrysler Dodge Jeep Ram of Manassas, VA (the originally servicing dealership) completely falsified the multi-point safety inspection that they signed off on, sending my vehicle on public roads in Northern Virginia, some of the most dangerous traffic in the world. Of note, I also drive the vehicle to/from work almost 100 miles per day during the week to/from Stafford, VA to Washington, DC. If I had not inspected the vehicle myself and waited until the first appointment for the first oil change, this would have without a doubt, caused a serious accident in [XXX] , which is the route i mostly travel, a large amount of property damage, likely injury or possible death, due to the absolute fact that I would have lost all brake fluid and have had no brakes at all. There were no warning lamps illuminated at all. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

There is an active parts recall for some Gladiators, Recall 26A, for the right rear axle shaft. This part on my vehicle has been failing for over 6 months. The ABS system, Traction Control, and 4WD system have active fault codes, preventing these systems from working as intended. In the last month, this problem has become unsafe due to 3 separate incidents where the traction control has triggered during normal driving conditions, causing the vehicle to become inoperable. In each of these incidents, I was travelling in a straight line, on dry roads, when the traction control system activated, preventing all acceleration to occur. In the first occurrence I was in a tunnel, and unable to pull over as there was no shoulder. This was driving in a straight line, accelerating up to about 15 mph before the traction control kicked in and disabled the drive train. Traffic was able to safely pass me while I coasted through the tunnel with my hazards on. Turning the vehicle off, then back on was the only way to cure this condition. The next 2 times were both at unprotected stop signs, meaning cross traffic did not have a stop sign. When I pulled out into the middle of the road, the traction control activated, causing the vehicle to lose forward momentum and power. One of these incidents, traffic did have to slow and alter course to account for my vehicles failure in the road. During the 6 months of the axle going out, the ABS system triggers at intermittent times during normal driving/braking conditions. I have tried working with the dealership where I purchased the vehicle, and with Chrysler directly. Both parties deflect responsibility to the other, stating there is no way to help escalate these problems because they are a recall item. I have been directed to wait for parts and to continue driving the vehicle, despite it seeming like a safety risk.

While driving multiple warnings appears on the dash including bus communication, airbag, transmission communication, and abs. The vehicles engine began to randomly change rpm. The transmission began to shift speratically and was unable to maintain speed. The vehicle would not allow me to turn on hazard lights to warn surrounding motorists. Similar warnings appeared on the dash once before and the vehicle would not start and left me stranded. When taken in for service for the no start issue, the dealer performed no repairs for this issue and stored P codes were cleared prior to the vehicle being returned to me. I am currently awaiting a service appointment for the issue that happened while driving.

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.
