2023 Ram 1500: ABS light or ABS activating

Filed Oct 27, 2026 · Acceleration, Brakes · LA

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

The contact owns a 2023 Ram 1500. The contact stated that while driving on several occasions at various speeds, the seat belt, ABS, check engine, and other unknown warning lights illuminated. The contact stated that the messages “Service Transmission – Continue in D – Do Not Shift or Turn off Engine until You Reach a Desired Location”, "Service Power Steering", "Service Parking Brake", "Park Sense Temporary Unavailable", "Service Transmission – Continue in D”, and “Do Not Turn off Engine”, “No Buss” were displayed. Additionally, the windshield wipers activated inadvertently. The contact stated that on one occasion, while in the middle of traffic, the vehicle was pulled over to the side of the road and the contact attempted to turn off the vehicle by depressing the ON/OFF button, but the vehicle failed to turn off. After several attempts, the contact was able to turn off the vehicle. The contact turned off and restarted the vehicle several times to reboot the vehicle. When the vehicle was restarted, the vehicle failed to accelerate. The vehicle was towed to a dealer where it was diagnosed that there was an unknown issue with the wiring on the passenger’s side of the vehicle. The vehicle was repaired, but the failure reoccurred 1 year and 7 months later. The vehicle was taken to another dealer where it was diagnosed and determined that the CAN-C network was offline, the OCM was the module taking the bus down, circuit D13 was at 0.37 volts instead of 2.7 volts, and D14 had 0 volts, indicating a ground short. A connector was found in the wiring diagram closer to the OCM that should only have the OCM in it. D14 was rubbed through on the seat frame where it ran down from XY420A. While the technician was removing the wiring harness, the short to ground was no longer present. The rubbed section of the wire was cut out, and a new wire was installed, but the failure reoccurred within 24 hours. The vehicle was taken to the same dealer where it was diagnosed and determined that wiring needed to be resecured. The vehicle was

2023 Ram 1500 V6 eTorque, 40,000 miles. Two stalling incidents have occurred under different conditions. Incident 1: While towing approximately 4,000 lbs, the 12V battery began slowly draining while the vehicle was in motion. Battery voltage gradually dropped below 10 volts until the engine shut off completely while driving. No warning lights appeared prior to shutdown. Jump start restored normal operation. Stored fault codes retrieved afterward showed 16 simultaneous voltage fault codes across every major module including ECU, ABS, EPS, DDM, PDM, CSWM, IFC, PTS and SCCM — all logging system voltage below allowable range simultaneously, consistent with a complete charging system failure. PCM also logged a U0401 code indicating implausible data received, consistent with the PCM losing stable voltage. Incident 2: After approximately 45 minutes of low-speed driving (5-10 mph) in a Walmart parking lot, the vehicle stalled without warning on a busy road in [XXX] . My wife and two young children were in car seats in the vehicle at the time. The engine cut off completely in live moving traffic with no warning. I was forced to exit the vehicle and jump start it in the middle of traffic while my children remained strapped in their car seats, creating a serious and dangerous situation. Jump start restored normal operation. On the subsequent highway drive home, battery voltage was observed declining from 14V to 13.2V over the course of the drive, suggesting the charging system is unable to maintain adequate voltage output. This is a known recurring issue with the Ram eTorque mild hybrid system. the federal safety agency has an open preliminary investigation into eTorque stalling on 2022 Ram 1500 models. The MGU, BPCM and PCM are all covered under the 8-year/80,000-mile Federal Emissions Warranty verified via VIN. PCM software updates have never been performed on this vehicle. Vehicle is being brought to an authorized Ram dealership for diagnosis and warranty repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U

The vehicle was sold with oversized 35-inch tires but was never recalibrated for speedometer, odometer, or tire pressure monitoring systems. The vehicle’s speedometer reads approximately 7 mph slower than actual speed, making the odometer inaccurate as well. This affects braking, ABS, traction control, and engine timing. The door placard still lists the original 265/70R17 tires, meaning the vehicle no longer meets the safety certification indicated by the label. The dealership did not disclose these modifications. I have had two tire failures due to rubbing and unsafe fitment.

On 3 separate occasions the truck has completely broken down while traveling 60-84mph. Each time, while in motion, the check engine and battery lights come on on the gauge cluster. Voltage starts rapidly draining from the battery indicator before systems start being shut down. Fiirst is entertainment, then climate, the ABS, then steering, and then all power and engine loss. I almost lost control the first time while trying to make it safely over to the soft shoulder. Each of the three times this had happened, the truck was completely dead in the side of the road and was towed to a dealership three times. The truck was towed to 2 different dealerships. The first two times to Imperial Dodge where they charged the battery the first time and did a software update the second time. Most recently the truck had been at DCH Temecula, for two weeks, where nothing has been done due to them not being able to recreate this issue. They recommended that I take video, while driving, as the issue happens live. This is a major safety issue in general but unacceptable that the manufacturer and dealerships only solution is for me to put myself and my family in jeopardy, and break California law, to diagnosis this massive unsafe vehicle.

I took my vehicle in to the dealer for a safety recall related to the ABS control module. Apparently it was software related and they said they would update the software. After the update a "Marketing Notification" shows up on my screen upon engine start and engine shutdown. It says Discover AppMarket! In-vehicle marketplace for Learning, Gaming & Connected Services. Tap Apps-Other-AppMarket-Games & Digital Store. Call 800‑777‑3600 for questions or if you choose to opt out of these messages. This is unbelievably criminal.
