Filed Sep 28, 2026 · Acceleration, Electrical · CA

2019 ram 1500, upon decelaration when coming to a stop, or to very slow, vehicle will drop into neutral/ lose ability to accelerate. Gear selecter dial indicator light will flash, dashboard message "shift to p, then select desired gear" will be displayed. During this time vehicle is unable to accelerate until driver come to a complete stop, shifts into n, then back into drive. Vehicle has lost ability to accelerate in the middle of active intersections, with active oncoming traffic from both infront and behind. Vehicle has had TCM flashed, valve body replaced, transmission replaced, and software verified up to date with no repair solving issue. Vehicle issue ongoing.

​SUMMARY OF ISSUE: Water intrusion from a defective factory rear window seal flooded the Radio Frequency (RF) Hub module, causing severe, dangerous network communication (CAN bus) failures while driving. The removed RF Hub has been retained by the owner and is available for physical inspection upon request. SAFETY RISKS: Power steering repeatedly seizes/locks up while driving. ​Vehicle completely stalls and freezes in active intersections and at highway speeds on I-95. ​Instrument panel illuminates with all warning lights ("Christmas tree" dash) and prompts driver to "Put Vehicle in Park and Put Back in Drive" while actively moving in traffic. ​Vehicle experiences complete power loss, creating a severe rear-end collision hazard. ​TIMELINE & MILEAGE: 60,328 mi (Dec 2022): Initial electrical glitches reported to dealer prior to 100k warranty expiration. ​92,733 mi (Sept 2024): Reported ongoing key fob loss, electrical anomalies, and TPMS drops. ​168,492 km (~104,696 mi): Scanned multiple CAN bus "U-codes" (documentation available). ​104,716 mi (Sept 22, 2025): Leaking rear window seal repaired by dealer. ​~114,000 mi: Worsening symptoms and total vehicle stall. ​DEALER FAILURE & DENIAL: When repairing the window seal, the dealer failed to inspect for interior water damage or check underlying electronics. They refused to open/inspect the RF Hub, claimed they could not reproduce the intermittent issue, and are attempting to blame an unrelated "star connector." The owner opened the RF Hub casing and photographed clear galvanic solder corrosion and water damage directly under the leak point. Component has not been inspected by police, insurance, or manufacturer reps. PRIOR SYMPTOMS: Progressive TPMS loss, "Key Fob Not Detected" while driving, throttle surges at stops, parasitic battery drain, and full dash light warnings—worsening with humidity and rain.

The ABS control module and Hydraulic Control module are faulty and available for inspection. My safety is at risk because the vehicle will go into a skid upon hard braking (ABS not fuctioning), the vehicle will spin tires upon acceleration (traction control inoperative). The above listed components have been determined faulty by both the dealership and an independent service center. The component is on national backorder (according to the dealership) due to how common this issue is. The ABS, traction control, and brake light stay illuminated as well as the dashboard "message center". I'm in disbelief of there not being a recall for something so dangerous. I travel for work and tow my travel trailer and now am unable to do so safely. The fact that the modules are on backorder is a testament to how common this issue is.

My 2019 Ram 1500 has had a failed ABS control module for several months, which disables critical safety features including ABS, traction control, and cruise control. While entering the interstate on an on-ramp during light rain and under normal driving conditions, the loss of traction control contributed to a sudden loss of stability, causing the rear of the truck to break loose and the vehicle to spin. No other vehicles were involved, but the situation created a serious safety hazard and could have resulted in a crash. The vehicle continues to operate without these safety systems, significantly impairing safe handling and braking. I have been informed that the required replacement module is on extended backorder with no estimated availability, leaving the vehicle in an unsafe condition for an extended period of time.

RF Module lost connection to CAN Bus and caused the vehicle to shutoff while driving. Symptoms include messages about key fob not within range and TPMS not able to communicate with sensors. RF Module was replaced however the issue returned. Other symptoms include parasitic draw caused by RF Module that in turn causes the system to report low voltage while driving. Vehicle has left me stranded on more than one occasion due to RF Module failures. These situations where preceded by no starts and shifter errors. Most of these issues can temporarily be resolved by disconnecting the main battery for extended periods. Dealer or service center has not reproduced the issue. Dealership inspected the RF module during installion of a new RF module after a water leak. The issue first appeared after the dealership repaired the "backlite" window, which was leaking on to the RF module. I suspect this might be related to system updates installed during the window installation service call. All of this started in early 2024.

SEE FULL COMPLAINT NOTES IN ATTACHED PDF; SUMMARY HERE (you do not provide sufficient space to provide all info you request) I own a 2019 Ram 1500 4WD Limited (not eTorque). On multiple occasions, the vehicle has unexpectedly shifted out of Drive into Neutral while driving. When this occurs, a warning chime dings and a message on display directs me to “Shift to Park”. The vehicle immediately loses forward power (because it has shifted itself to Neutral), until I come to a complete stop, shift to Park, and then shift back to Drive to move forward. Usually the engine stays on, but on at least one occasion the engine turned off and I had to restart. This has happened at least five times total, including three times within the past month. The events have occurred while decelerating to a stop, braking but not stopping, and accelerating from a slow down. Each time, I experienced a sudden and unexpected loss of propulsion, requiring me to stop the vehicle in traffic, shift fully into Park, and then reselect Drive before the vehicle would move again. These incidents have occurred in active traffic situations and have placed me and others at risk of a collision due to the sudden loss of power (SEE DETAILS IN PDF). I previously brought the vehicle to a dealer for this issue after it had just occurred (~1 year ago, before the recent increase in frequency); however, the dealer stated that the vehicle did not throw a code, or no code was stored. They could not replicate the problem and no repair was made. There are at least 55 the federal safety agency complaints filed that appear the same as my issue; none appear to have been resolved by dealers or RAM. This appears to be a systemic safety defect involving the powertrain and electronic shifting system. The unexpected loss of propulsion in traffic presents a serious risk of injury or death. I am submitting this complaint due to the ongoing and unresolved safety concern. I am scared to drive my family in my vehicle until it is known to be fixed.

The contact owns a 2019 Ram 1500. The contact stated that while driving approximately 70 MPH, there was an abnormal sound coming from under the hood, and a burning fuel odor was entering the cabin of the vehicle through the air vents, before the vehicle lost automotive power. The electronic throttle warning light was illuminated. The vehicle was towed to a local dealer, where it remained for further investigation. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 50,000.

On August 20, 2025, my 2019 Ram 1500 Laramie was taken to the dealership for diagnosis after showing the warning “Electronic Stability Control system needs service,” along with a flashing check engine light. The dealer pulled diagnostic codes and documented U0403-00 (“Invalid Data Received from Anti-Lock Brake System (ABS) Control Module A”) as well as other communication errors. This is the same defect covered under Stellantis’ recall for ABS module failures that disable stability control in 2019 Ram trucks. However, my VIN is not included in the recall. A few years ago, the truck experienced the same warning, but the problem cleared on its own. Now it has returned and is documented with codes in the dealer system. The dealership acknowledged other recalls were already completed on my VIN, but refuses to perform this safety recall since my VIN is not listed. ABS and ESC failures are not the result of consumer behavior. This is a faulty system created at the time of vehicle manufacturing. There has been no accident or outside damage, and nothing the owner could have done to avoid this issue. The defect lies with the vehicle’s design and creates a serious safety risk for the driver and others on the road. I believe my VIN was excluded from the recall in error and request that the federal safety agency investigate and expand the coverage.
