Ram 1500 abs comes on

Filed Nov 4, 2026 · Brakes, Electrical · FL

I am writing to file a formal safety complaint regarding a widespread defect in the Anti-Lock Brake System (ABS) Control Module and Hydraulic Control Unit (HCU) on my 2016 Ram 1500. The ABS system on my vehicle has suffered an internal failure, resulting in an active ABS dashboard warning light, total loss of traction control, and immediate electronic disabling of both the cruise control system and the four-wheel drive (4WD) system. Disabling ABS and the 4WD system leaves the vehicle unable to adapt to hazardous road or weather conditions, creating a significant safety risk. This exact failure pattern mimics identical ABS defects that parent company Stellantis/FCA has previously recalled on heavier-duty Ram platforms (such as the federal safety agency Recall 24V‑896), but the 2016 half-ton models have not yet been included in a mandatory remedy campaign. I request that this issue be documented and investigated as a potential safety defect requiring expanded remedy coverage.

The ABS module has failed, leaving our truck inoperable. We can not find a new part for replacement. Our local dealer that we purchased the vehicle from said they do not have access to a new part either. Mileage is 99581. ERROR CODES: Service electronic braking system, service shifter words come on. The brake light, seat belt light, and several other miscellaneous lights come on the dash. When hooked up to a code reader: Invalid data received from ABS control module A, lost communication with body control module, High Speed CAN communication Bus, lost communication with ABS control module A DTC Severity 3of3.

i was driving and the headlights dimmed and went out, almost causing accident. I brought it to my mechanic and at [XXX] it says the alternator on your vehicle may experience a rapid alternator failure due to diode thermal fatigue. Variability in the failure mode ranges from no output, reduced output, and/or a fully shorted to ground condition. Depending on the alternator failure mode and timing, the vehicle electrical system voltage may drop to critical level, disabling systems such as ABS, ESC, and ECM and/ or the Central Body COntroller. the driver will have limited or no detection of the alternator failing, which can result in vehicle shutdown while driving, increasin the risk of a crash and/or an underhood electrical fire. I can't reach anyone to help me with this problem with the FCA Recall Assistance Center. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Brakes, ABS , shift sensor, in drive and would not move had to turn off in heavy traffic and then put in Drive and would go for a while, leveling off, every light was in a rolling script on my dash! Finally got to place that I could park it.Finally was able to get someone to get it home. 1 hour away. My husband is [XXX] and has dementia, can hardly walk. I am [XXX] and am responsible caregiver to him. We were in getting off work traffic when this was going on…Yes my vehicle is available to be seen. I can not drive it for fear of happening again and causing more trouble. Yes we were surely in danger as so were others in traffic. Yes has been confirmed by dealership and other mechanics. Everyone says they do not have the modular to fix it and have no idea when it might come in! I owe 1500.00 on this vechicle and have been very pleased with it. Even with getting recalls fixed. But now we have this very nice truck that we can’t drive, or trade or sale! Our other vehicle is a 2007 FJ Cruiser and has 335,000 miles on it. Bought it new and have had no problems with it. Just a little Leary for us to start out to dr. Appointments or whatever else comes up, I had always felt safe in our truck, but now I am afraid to drive out of driveway. We were told if that had part to fix it , it would be 1600.00 dollars to fix. We live on fixed income and this has caused us much despair. I was not aware of trouble with this problem until now. But have been made aware that we are not the only ones. I would love to hear from you and with a solution to this mess!!! Thank you. [XXX].

The contact owns a 2020 Ram 1500. The contact stated that the vehicle experienced intermittent starting failures. In addition, the contact stated that while accelerating from a complete stop, the vehicle hesitated and the message "Please Put the Car in Park" was displayed. The vehicle was driven to a gas station, shut off, and refueled; however, the vehicle failed to start immediately and only restarted after approximately 30 minutes. The battery was replaced by AAA. The vehicle was taken to the dealer several times, where the contact was informed that no failure was found and the failure could not be duplicated. Several messages and warning lights, including "Key Fob Not Detected", "Parking Brake Error", the ABS warning light, and the traction control warning light were illuminated during the failure. The dealer notified the manufacturer of the failure, and the technicians advised the dealer to replace the key fob; however, the failure persisted.

I am filing this safety complaint regarding a defective ABS Hydraulic Control Unit (HCU) on my 2023 Ram 1500 Classic TRADESMAN CREW CAB 4x4 5.7L Hemi with approximately 87,000 miles. DEFECT DESCRIPTION: The ABS HCU periodically fails, resulting in complete loss of anti-lock braking, traction control, electronic stability control, 4WD and cruise control. This is an identical failure mode to the defect addressed under the federal safety agency Recall 24V‑896, which covered 2017-2018 Ram 2500-5500 trucks. My 2023 Ram 1500 Classic uses the same or substantially similar HCU component and is experiencing the identical failure. SAFETY RISK: The loss of ABS, ESC, 4WD and traction control significantly increases the risk of a crash, particularly in adverse weather conditions. This is not a minor inconvenience — it is a serious safety hazard that FCA/Stellantis has already acknowledged in heavier-duty Ram platforms. MANUFACTURER KNOWLEDGE: FCA was aware of this defect as early as 2016 based on warranty claims and customer complaints. Despite issuing Recall 24V‑896 for heavier Ram trucks with the same HCU failure, FCA has failed to extend recall coverage to the 2017-2024 Ram 1500 DS models, leaving thousands of owners without remedy. FINANCIAL IMPACT: Repair estimates range from $1,200 to $2,000. The part remains on backorder or engineering hold, making timely repair impossible through normal channels. REQUESTED ACTION: I respectfully request that the federal safety agency: 1. Open a formal investigation into the 2023 Ram 1500 Classic ABS HCU failures for thousands of trucks, 2. Compel FCA/Stellantis to expand Recall 24V‑896 or issue a new recall to include the 2017-2024 Ram 1500 DS models. 3. Require FCA to reimburse owners who have already paid for this repair out of pocket
