2022 RAM 2500

The contact owns a 2022 Ram 2500. The contact stated that while driving at an undisclosed speed, the vehicle intermittently went into LIMP Mode and failed to accelerate as needed. The contact pulled over and turned off the vehicle. The failure failed to be self-corrected after the vehicle was restarted. The vehicle was taken to a transmission specialist, who was unable to duplicate the failure. The contact was informed that the failure was electrical, and an unknown sensor was replaced; however, the failure persisted. The vehicle was taken to the dealer, who discovered a leak in the transmission pump. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and directed the contact to the dealer to have the transmission replaced. The failure mileage was approximately 120,000.

Per mopar recall ZA3 transmission tube and dipstick recall. When completed at Orange Coast Ram [XXX] , dealership completed recall, removed original dipstick, and provided a 15" locking dipstick the does NOT provide needed transmission fluid level. Inquired in Orange Coast Ram service department, stated they will not provide needed 44"dipstick to monitor trans fluid. I cannot order, purchase the needed dipstick, creating a dangerous situation if fluid is low, and will result in transmission damage and possible dangerous condition if transmission fails while driving/.towing. I was told I will have to go to dealership and have the level checked, which is a routine needed owner maintenance job CORRECTIVE MEASURE: PROVIDE NEEDED 44" DIPSTICK TO MONITOR TRANSMISSION FLUID LEVEL INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2022 Ram 2500. The contact stated that while driving at an undisclosed speed, the RPM fluctuated. Additionally, the vehicle made an abnormal sound while slowing down to come to a stop. The vehicle was taken to the dealer, who discovered burnt transmission fluid and replaced the transmission, but the failure persisted. The vehicle was taken back to the dealer; however, the cause of the failure could not be determined. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 10,000.

I have a clunk to when coming to a stop, the transmission is down shifting, and just before it comes to a complete stop, the truck has a clunk that is felt through the vehicle and heard. at times while stopped the vehicle will lurch forward as though you have been hit from behind. The truck has been back to the dealership several times for this problem, two different dealerships because the first one gave up and was suggested to take it to another dealership per Ram. The truck has been shut down completely two time to put in relearn mode, three transmission replacements, four valve body replacements, and they wanted to put a fourth transmission in the truck, but the mechanic said he doubts thats the problem to Ram, and so now they want to say that its operating as design, Ram asked me to take it to a third dealership, so I did, the mechanic and I went for a drive in the truck, the mechanic said there is definitely a problem, but he would not take on this job because he would not want to deal with Ram and there politics. So that leaves me driving a 2022 Ram 2500 truck I purchased [XXX] that did not have this problem until after purchase six months later. Ram customer care has offered money for my inconvenience, I said I just want my truck fixed, they said they are not going to do anymore. I have a vehicle that has been in the shop for a total of eleven months since i have purchase it, has not been fixed, and every time I come to a stop I cringe because I know it is going to clunk and I didn't even take my new travel trailer out the last year because of fear of it breaking down. I paid good money for this truck, and it seems Ram does not care, they got my money and so they got what they wanted. If Ram cannot fix this, then let's talk about getting me in another truck. I am really frustrated, and do not know where to turn. Thank you [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting a recurring safety defect involving hydraulic lifter failure in Ram trucks equipped with the Cummins diesel engine (model years 2019–2024). This issue is widely acknowledged by Stellantis and multiple dealers. It typically begins with a knocking sound and has been documented in many cases to progress to complete engine failure. My vehicle has fewer than 20,000 miles. The lifters were already replaced once, which required the cab to be removed. Within less than 400 miles of that repair, the knocking sound has returned. I brought the truck to a second dealer, who confirmed the problem and informed me that Stellantis has an active STAR case acknowledging the defect. They stated there is currently no known permanent fix. This defect presents a serious safety concern. Sudden engine failure while driving, especially under load or at highway speeds, could lead to loss of power, loss of steering/braking assist, and potential accidents. In my situation, I frequently travel with family members who have medical conditions, and being stranded in hazardous or remote conditions poses significant risk. At this point, my vehicle is not reliable or safe to operate. I am requesting NHTSA investigate the hydraulic lifter defect in 2019–2024 Ram Cummins trucks due to the safety implications and the lack of an available permanent repair.

Dodge Ram started making typewriter sound coming from the engine. Took the Ram to the dealership and they found 3 damaged push push rods and 3 damaged rocker arms. Dealer refused to address the metal shaving from the internal damage floating around the engine. Engine had 32k miles on it and oil was changed at 7 to 8k miles intervals.

The Mass Air Flow (MAF) sensor on my 2022 Ram 2500 failed, causing multiple system malfunctions. It triggered inaccurate Diesel Particulate Filter (DPF) codes and showed abnormally high idle hours that do not reflect actual vehicle use. This defect is tied to a known issue identified by Stellantis in Technical Service Bulletin #18-002-24, which acknowledges improper MAF sensor calibration or compatibility on vehicles like mine. The bulletin was verbally confirmed by the dealership as applying to my truck. This faulty sensor caused emissions system errors, degraded engine performance, and may impact emissions compliance. There was a persistent check engine light, reduced fuel economy, and the risk of engine derating. The problem was reproduced and confirmed by Encore Chrysler (Mobile, AL), an authorized Ram dealership. Stellantis has agreed to cover the repair under Goodwill, but the issue appears systemic. Safety was potentially compromised by inaccurate sensor data that may cause sudden engine derate or failure during operation. Additionally, the incorrect idle hour readings could affect warranty determinations and long-term diagnostics if not corrected. The check engine light first appeared on May 21, 2024. The vehicle has been out of service since May 22, 2024, and repairs are still pending. The MAF sensor and affected systems are available for inspection upon request. This issue may affect a broader set of Ram 2500 trucks, and given the manufacturer’s internal bulletin, it may merit a recall review.

Transmission issues began at less then 10K miles when the vehicle was new. Initially experienced a noise and slam into reverse gear. The dealer initially claimed the noises were normal or could not replicate the issue. Over time, the vehicle developed a hard shift between 1st and 2nd gear and between 4th and 5th gear. Despite multiple repair attempts by the dealer, the problem persisted. After spending 94 days at the dealership, the transmission was replaced with a refurbished unit of unknown age at approximately 26,000 miles. According to the dealership representative, a manufacturing defect in the transmission case was ultimately identified as the cause of the failure.

1. Complete Brake Failure. No warning lights came on. There is no emergency warning system for Brake Failure. This could have been catastrophic. This could have turned deadly if we were driving on the highway with no warnings Dec 15, 2024 I drove the truck during the day on the highway and made various stops for Christmas Shopping. I went for dinner with my Family. After dinner climbed into the truck and depressed the break and started the truck. Once the truck started the break pedal could be pushed to the back floorboards. I know this was not right. Turned the truck off and started it again and up it in drive thinking it would correct. It did not turned onto a sidewalk put he truck in park and called a towtruck. 2. The 12" display goes black constantly. Even after several software upgrades. You cannot see heat/radio/ mapping/ phone system nothing it completely shuts down 3. Transmission, when you stop and then drive slowly, press the brakes lift off the brakes slightly the truck lunges forward so you really have to be careful or you will crash into the car in front of you.
