2019 RAM 1500

The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation to an EA in order to 1) determine engineering specifications of internal pump components that are correlated with pump failure leading to loss of motive power or other safety related hazards, 2) identify vehicle populations equipped with alleged defective pump variants, 3) assess if vehicles equipped with alleged defective pump variants result in an unreasonable risk to motor vehicle safety and 4) gather and review any other relevant information related to high pressure fuel pump failure associated with the subject populations of recalls 21V586, 21V880, 21E094, 22V406, 22E048, 22V767, and 22E087.Review of the above information will allow NHTSA to confirm root cause and recall remedy viability, and identify and evaluate vehicle populations equipped with pump components that may pose an unreasonable risk to motor vehicle safety.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 11257550, 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 11377871, 11378173, 11384377, 11386063, 11387018, 11399710, 11402550, 11415339, 11418868, 11418870, 11427075, 11434276, 11436807, 11437226, 11437249, 11437273, 11437292, 11437294, 11437394, 11437399, 11437403, 11437405, 11437423, 11437528, 11437565, 11437579, 11437580, 11437590, 11437679, 11437744, 11437781, 11437842, 11437993, 11438006, 11438008, 11438121, 11438138, 11438155, 11438392, 11438629, 11439359, 11439879, 11440397, 11443030, 11446542, 11448163, 11453556, 11458918, 11460558, 11469337

The contact owns a 2019 Ram 1500. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated shortly afterwards. Several unknown warning lights were illuminated. The contact stated that the transmission failed to shift out of first gear. The message “Slow Down - Service Shifter” was displayed. The contact associated the failure with TSB: (23-029-22 Rev. A); and referenced an extended warranty coverage. The vehicle was taken to a local dealer, where it was diagnosed and produced DTC: U0645 - Lost Communication with Active Air Dam Module. The vehicle was not repaired. The manufacturer was contacted and opened a case. The failure mileage was approximately 137,700.

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.

​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.
