When driving, I get a prompt on my dash to switch to park and then desired gear. I get no response from my accelerator until I do so. This particularly happens when I’m slowing down and accelerating after a stop signs or traffic lights. Happens while in the middle of intersections. This happened about 7 times in the past month. Dealership said they couldn’t find a problem when I took it in. They did a transmission re-learn which I paid for and the issue happened twice since that appointment.
Water was detected. the federal safety agency Case (#11742618)
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.
I was on the highway when the vehicle alerted me that shift was unavailable then the auto start/stop was unavailable then the airbags were unavailable then my FUEL and my MPH were not reading. My windshield wipers started all on their own and could not be turned off! And my EMERGENCY LIGHTS WERE INOP. I LOST POWER STEERING and was locked in gear! All while in morning rush hour traffic on the highway! The vehicle gave me a notification to get to my destination before turning it off or changing gears because it would not go back into gear. I got off the highway as safely as I could without EMERGENCY LIGHTS OR TURN SIGNALS and proceeded to a stop light. While slowing down I had no steering control. I pulled over and had to force the wheel to turn then I attempted to accelerate to move and had no power. So I was stuck. I had emergency services come and tow my vehicle to Chevrolet of Homewood at that point who is currently looking at it.
019 Ram 1500 5.7L eTorque MGU (Motor Generator Unit) failed on 08/29/2025 at 62,105 miles. Vehicle died on road and would not restart, creating a safety hazard. Dealer confirmed battery was severely discharged due to MGU failure — alternator was not putting out voltage necessary to charge battery, resulting in failed MGU. Vehicle was inoperable for 109 consecutive days (08/29/2025 through 12/16/2025) due to Stellantis parts backorder with no ETA provided. MGU is covered under Federal Emission Warranty (8 years/80,000 miles) per FCA US LLC 2019 Ram 1500 Warranty Booklet Section 5.1B. Stellantis denied all warranty obligations and failed to respond to a formal $40,125.00 certified mail demand for consequential damages. This defect is subject of active class action litigation: Fisher v. FCA US LLC, Case #2:23-cv-10426, E.D. Michigan
The truck went into park from drive on its own . The emergency brake was also activated after going into park. The shifter knob kept switching from drive into park every time I slowed down at a light or stop sign.
System/Component Malfunction: High-voltage hybrid powertrain system failure. Code P0DAF-00 (Hybrid EV Battery Cell Balancing Circuit) is present and locked in the Hybrid Control Processor (HCP). Vehicle is available for inspection. Safety Risk: Operating a vehicle with an unresolved high-voltage hybrid cell balancing defect poses an immediate safety risk. Cell imbalances can cause sudden loss of motive power at highway speeds, propulsion shutdown, or an increased risk of a thermal event in the high-voltage pack. The manufacturer (Stellantis/RAM Care) refuses to provide a written safety determination, yet the dealer instructed me to continue driving a compromised high-voltage system on public roads until the failure worsens. Dealer Confirmation & Inspection: Confirmed and reproduced by authorized dealer (Ron Tonkin RAM) across multiple visits: Feb 25, 2026 (RO 502329): Code P0DAF-00 present. Dealer performed a BPCM software flash, which failed to resolve the underlying fault. June 2026 (RO 504097): Held for 10 days. Technician documented: "Scanned codes and found code P0DAF-00- Hybrid EV Battery Cell Balancing Circuit present but code is stored (not active) and also not stored in PCM, only the HCP." Tech test-drove 97 miles but corporate engineering (STAR) rules prevent parts authorization until the code migrates from HCP to PCM as an active fault. Dealer explicitly instructed me to drive it until it triggers a hard failure. Warning Lamps & Symptoms: First appeared Feb 25, 2026, via a yellow Check Engine Light. The light intermittently cycles on/off as the computer stores the code, but the underlying high-voltage defect is completely un-repaired.
When driving the truck the power steering would go out and make the truck almost impossible to turn. This is dangerous when driving as you cannot turn, avoid a collision, etc. I've had vehicles without power steering, and this was like the truck is actively pulling against you when trying to turn. The dealership did a diagnostic and said the power steering rack (electronic) needs to be replaced completely as it's going out. I'm not sure if it's related, but I've had other issues before this where my lane assist and cruise control would flash while in use and all turn off while driving down the road as well. There was no obvious check engine light or codes for this, just the occasional shutting off of my systems and power steering while operating the vehicle.
The passenger airbag in my 2019 RAM 1500 (VIN: [XXX] LP: [XXX]) is completely missing. The dashboard was cosmetically repaired to hide the absence, and the warning light was tampered with so no airbag/SRS alert appears. This was only discovered during a recent inspection; I had no prior warning. Inspection by an independent service center is scheduled and I can provide the vehicle for examination upon request. This creates a severe safety hazard, for years I've driven with no passenger airbag protection and false reassurance from a working dashboard. The issue was not disclosed by the selling dealer. I have photographic evidence and can provide all records upon request. Problem has not been addressed by the manufacturer, dealer, or police/insurance representatives yet. Safety of all occupants was unknowingly put at serious risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Car accident. Repaired tires due to abs. Also backlite repair. Leaking water.
SEVERE SAFETY HAZARD: CASCADING ELECTRICAL FIRE RISK. My 2019 Ram 1500 suffered a catastrophic electrical failure while driving. The alternator's voltage regulator melted, overcharging the system and causing the battery to boil and vent toxic sulfuric acid fumes into the cabin, creating an immediate respiratory and fire hazard. This is the direct result of Manufacturer Defect XL1/XG1 (Rear Window Leak). I have physical dealer records proving Westgate Ram held this vehicle for 19 days in Aug 2022 to fix Water Leak Code 09H2OLEAK. They returned the vehicle claiming it was fixed, but I have geolocated photos showing the window leaking heavily just 17 days later. Because the leak was never resolved, water continuously entered the rear cabin, corroding the RF Hub and creating a parasitic drag that destroyed the electrical grid. CRITICAL NEGLIGENCE: On June 1, 2026, Stellantis Corporate (Case XXX) acknowledged the severity of the fire risk by immediately inquiring if Emergency Services had been contacted, yet subsequently refused to offer a safety tow. When I attempted to escalate, their agents [XXX] , [XXX] , [XXX] , [XXX] ) refused to provide IDs. Furthermore, my phone number is now being rejected by their system; calls to their support line immediately fail or disconnect, leaving a fire-risk vehicle stranded at my residence with no recourse.

Lost power while driving down the highway. All the dash lights and windshield wipers turned on and lost power steering. The steering gear assembly failed without warning.
I am currently continuing to make monthly payments of $735 on this vehicle while it remains inoperable due to a manufacturer parts backorder. Since 04/01/2026, I have not had use of the vehicle, yet I remain financially responsible for it without a clear timeline for repair completion or alternative support. My vehicle has been inoperable since 04/01/2026 due to failure of a hybrid battery system. The required replacement part is on indefinite backorder with no estimated availability date provided by the manufacturer or dealer. Despite multiple escalation attempts through Ram Customer Care and assigned case management, there is no confirmed timeline for repair completion. The vehicle remains unusable while payments continue. This raises concern regarding manufacturer parts availability for essential hybrid system components and prolonged vehicle downtime without resolution.

Manufacturing defect in the rear window frame (Backlite) causing severe water intrusion. Water is pooling directly onto the RF Hub (Radio Frequency Hub) electrical module and wiring harness. This creates a high risk of unintended vehicle shutdown while driving or a total electrical short-circuit/fire. This is a known issue documented in TSB 23-016-21 and Warranty Bulletin D-23-17, yet the manufacturer is refusing to honor the 8-year warranty extension for my specific VIN despite the safety risk.
Intermittent total electrical communication failure ('No Bus' error) triggered by warm weather. While driving at any speed, the instrument cluster gauges drop to zero and the vehicle loses all control of turn signals, hazards, cruise control, and windshield wipers. This has created several near-miss situations in traffic and rain. The failure also prevents the vehicle from starting. Despite multiple dealership visits and an open Star Case, the manufacturer has failed to provide a remedy for this safety-critical defect.
Instrument cluster does not work. This has been happening for months now, making vehicle speed and none of the guages or warning lights visible.
The backup camera sometimes doesnt show the lines. also the camera sometimes glitches while backing up. And the infotainment system sometimes wont let the music out of the speakers even turning off and on the stereo/truck.
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.
First off the service shifter keeps coming on and off every time I take it to the dealership it’s off so they can’t read the code. Then the parking sensors keep coming on saying unavailable. Today when the service shifter came on, it went right back off and then when I went to turn onto the highway it felt like the truck stalled for a second then it started driving normal again and down the road. The service shifter light came back on, then went off. All recalls have been fixed on this vehicle and when I took it in and was charged $300 for a diagnostic, they couldn’t figure out what was wrong because the light wasn’t on anymore.
Vehicle lost all power and shut off on two occasions during operation. Luckily steering and breaks were not impacted. Dealership was unaware what could have caused the incident. However, a local shop identified the alternator/power generator as being faulty. Ram 1500 owners forums show this is a widespread issue. So widespread there is a 8000 part backorder to order an OEM replacement part. Local dealership stated the part has been on backorder for more than one year.
Has happened 5 times, I also replaced the battery with a new one. Cargo light switch cuts on by itself and drains battery.Issues with rear camera after battery was charged. Also CarPlay doesn’t work sometimes.

My ABS module went out in my 2019 Ram 1500 Rebel.. My service “Electronic stability control” , “Service Trailer Brake System”, as well as “Service 4WD” lights are all on.. i had Auto Zone hook the computer up to my truck and it had 2 codes. C2206-00: Vehicle Configuration Mismatch and U0403-00 Implausible Data Received From T-Case. ABS module failure. I did some online research and come to find out there was a recall on my model truck for the ABS system needed updated.. I check my VIN online and says there are no recalls on my truck.. I’m having the exact problems stated in the recall and have the exact model stated in the recall. I was never notified about the recall. My truck only has 68,000 miles on it. the federal safety agency Recall # 24V‑653. I don’t understand why my VIN wasn’t included in the recall. Thank you for your time
Rear view camera first began blanking out in the morning, when the temperature was below 64 degrees F. About 6 months later, the camera began blanking out completely (regardless of temperature). The camera image is supposed to appear on the left side of the rear view mirror. Now, instead of the picture, there is an image of a camera icon with a slash through it (indicating lack of input from a camera).
