2021 Ram 1500: ABS light or ABS activating

Filed Aug 2, 2026 · Brakes · TX

I received recall notification number 24V653000, Stellantis recall 75B. This recall is detailed as a software malfunction in the ABS control module to disable the electronic stability control system. This will cause the vehicle to fail. It was serviced at Don Davis Ram dealership in Arlington, Texas on November 11, 2025 and was advised they were going to do a software update. On July 27th , I contacted (formerly Don Davis) now Clay Cooley Ram dealership and spoke to a service representative, Jose Hernandez. I explained that the brakes feel very spongy and takes more time to slow the vehicle down (constantly have to brake several times when approaching other vehicles or at red lights). It is very noticeable and is dangerous for me and others on the roadway. He explained that I am now responsible for the diagnosis evaluation of $99.95 plus the fee to update the EBS software. Jose explained that everytime the brake system needs to be updated, then I am financially responsible for these fees because the 36,000 miles warranty has expired. I explained to him that I am guaranteed a "Lemon Law" protection in my purchase. In addition, this vehicle only has approximately 28,000 miles

The contact owns a 2021 Ram 1500. The contact stated that while driving at an undisclosed speed, the ABS warning light illuminated. Approximately six months later, while driving at an undisclosed speed, the check engine, ABS, stability control, and brake warning lights illuminated, and the "Auto Park Disabled," "Service Antilock Brake System," and "Service ABS System" warning messages were displayed on the instrument panel. The vehicle was taken to an independent mechanic shop, where it was diagnosed that the speed sensor and the wheel bearing needed to be replaced. Diagnostic trouble codes U0415, C0572, C053D, and C10F5 were retrieved. The speed sensor and the wheel bearing were replaced, but the failure persisted. The vehicle was then taken to a dealer, where it was diagnosed that the ABS module needed to be replaced; however, the vehicle was not repaired due to backordered parts. The manufacturer was notified of the failure. The failure mileage was unknown.

While driving, a deer entered the roadway. I applied the brakes to avoid hitting the deer and lost traction due to icy road conditions. The vehicle spun out and struck a utility pole. I later became aware of an open recall involving the ABS and/or electronic stability control (ESC) system for this vehicle. There were no warning lights, messages, or alerts before or after the incident. The vehicle did not maintain stability as expected during braking on ice. I am unsure whether the ABS/ESC system functioned properly at the time of the incident. The crash resulted in vehicle damage and property damage. To my knowledge, the vehicle has not yet been inspected by the manufacturer. The vehicle is available for inspection upon request. After crash, airbags did not deploy no fluids leaked no warning lights ever came on dash before or after crash

Electrical system shutdown including loss of all safety features (blind spot, emergency braking, abs, traction control, towing), climate control options (AC, Heat, window operations) and user interfaces (U-Connect screen, center gauge cluster). Initial warnings (2) on center cluster on listed- 1. Blind Spot Detection Disabled 2. 115 Volt Cargo Power Outlet On All electronics, controls were then disabled- black screens, inoperable controls. Passenger rear windows, sliding back glass, panoramic sunroof and drivers side mirror are the only working electronics other than speedometer. Upon inspection of all fuses, relays, battery, alternator, and checking all accessible wiring related to blind spot and auxiliary power and finding no defective issues, web searches were performed. Based on numerous other RAM owners on multiple forums on RAM trucks 2020 and newer with blind spot avoidance, we found a likely culprit in the driver's side brake light. Upon inspection of the left rear brake light assembly, a small hairline crack was located with signs of internal moisture/ condensation. After observing the internal moisture the drivers side rear brake housing was removed and disconnected for closer inspection and potential repair. While the driver side brake light assembly was removed, an instance occurred when my wife needed the vehicle. Upon and during the entirety of operation over the next 1.5 hrs driving approximately 63 miles, all electrical options worked as intended minus the blind spot avoidance and a new warning on brake lamps (obvious as tail light had been removed). During this time, the proximity sensor housing was removed from the assembly, water accumulation dried, and allowed to remain open next to a dehumidifier for 4 hours. Epoxy was applied over the hairline Crack, and any area that looked as if could be affected. Unit was reinstalled, however all electronic failure returned. Unit removed again to attempt humidity removal- all electronics res

While towing, my truck threw P00AF-00 Turbocharger Boost Control Module "A" Performance and ABS C121C-00 Torque Request Signal Denied codes and I lost power due to turbocharger not engaging. Alarms that were lit included CEL, Service Electronic Throttle Control, and the Stabilizer system. The safety aspect is the loss of power while towing on a highway. The original code was cleared by my hometown dealer and vehicle ran well. 130 miles later it happened again, cleared by dealer in Parkersburg WV On the way home it happened a 3rd time. After parking for half an hour the alarm lights went off and I had full power. A day later the CEL also went off leaving no evidence of a problem on my dash. The vehicle is scheduled at the local dealer tomorrow (9/29/25) The trailer and truck combination was well within the towing limits of the vehicle. There are various threads in RAM owner groups that allude to this problem in the Gen 3 Ecodiesel The truck is under an extended warranty from MOPAR...hope they resolve the problem

On May 16 2025 I started my truck and all the lights started flashing on my cluster( I took pictures) I drove down the street in my vehicle and it put itself into park. I drove back to my shop and called the dealership to make an appointment along with enterprise Rent-A-Car. I had the rental vehicle from May 16 through May 22. After the ABS module recall was performed on May 21, 2025, my 2021 Ram Rebel began experiencing electrical and mechanical failures affecting multiple vehicle systems. While driving at approximately 7 mph, the vehicle unexpectedly shifted itself into Park. Just like the separate occasion, the parking brake engaged while the vehicle was in motion. These events pose a major safety hazard. Since the recall, the following issues have occurred: •SERVICE BRAKES: Parking brake engaging while driving; ABS-related instability. •POWER TRAIN: Vehicle attempting to shift into Park and 4WD High without input. •ELECTRICAL SYSTEM: Dash lights flicker; HVAC system changes temperature settings on its own (e.g., jumping to 72°F); ongoing parasitic battery draw. •ELECTRONIC STABILITY CONTROL: Loss of system coordination and erratic vehicle behavior. •FUEL/PROPULSION SYSTEM: Sudden drop in fuel range readings (e.g., from 180 miles to 23 miles instantly). •VEHICLE SPEED CONTROL: Unexpected shifting and control changes during low-speed driving. •UNKNOWN OR OTHER: General system instability, rough driving behavior, and degraded performance. I was by the dealership when it went into park so I pulled in. The dealership has acknowledged the update was performed but refuses to inspect the truck until July 8, despite the escalating safety concerns. I believe the ABS module or its software update is causing communication failures across the vehicle’s CAN network, affecting critical systems. This vehicle is not safe to drive in its current condition. I was told because I did not purchase the vehicle at Wilder that I was not eligible for a loaner vehicle.

I just purchased a new truck on Friday and was told on car fax it had a open recall .On 1/20/25 around 0835 I arrived at service entrance and was not greeted or checked in after being told I would be charged a diagnosis fee for a very important safety recall related to ABS . I would like this incident investigated as it jeopardizes my and my family safety . Also told him the truck was under warranty and the wireless charging for phones was not working and got bring it back to where you bought it . I requested his supervisor and he walked away and acted like he was on the phone . This is my only local dodge dealer and now forced to goad hour south to get this fixed . I took a card because service manager never came out to address me as customer this dealership needs looked into .I think I was also discriminated at for being Caucasian as both service techs are Hispanic info email of service manager from card is Location of Dodge dealer . The person that wanted to charge me avoided me asking his name but had long curly hair and younger thug attitude guy . Also was told to leave after like anyone would be upset of a safety recall that are free and being told I would be charged. I’m requesting an investigation into this matter and or pursuing legal action . I know it’s a federal holiday and I have a 3 day weekend but hope this matter can be addressed soon as this is not right . Thank you .
