What 184 owners told NHTSA about the 2022 Ram 3500

While travelling in Southern California, I came to a stop to enter I8 on ramp. When I tried to start down the on ramp the truck didn’t want to move and a check engine light came on. The truck went into limp mode so would travel slowly along. I called Mango Auto who could diagnose it the following morning. I did not make it to the shop before the transmission failed completely and the truck wouldn’t move leaving me in traffic in a dangerous spot. Eventually I was towed to the shop in Yuma AZ. They diagnosed it as a complete transmission failure requiring a $10,000 replacement. FCA has issued an extended warranty, but my mileage is 16700 miles over. FCA has a technical bulletin on the issue with the Austin transmission, but has not but should have issued a recall. This failure To issue a recall left me stuck in a dangerous situation and could have resulted in a crash.

Vehicle lost drive via the transmission when it disengaged unexpectedly. Known issue that Stellantis classifies under "Customer Satisfaction Notice" instead of a recall. There are many examples of recalls issued by other manufacturers related to loss of drive via the transmission, so why is this being treated as a notice of inconvenience versus a safety issue? Issue is being addressed via a Technical Service Bulletin where units that fail are repaired after the fact versus proactively inspected and replaced.

The center infotainment stack screen refused to power up when starting the vehicle. The radio and hvac functions worked, but the screen would not turn on preventing the backup camera from functioning. Restarting the system twice and restarting the vehicle failed to get the system to function. Upon restart several hours later all systems appear to function normally. A video is available of the failure.

### **NHTSA Complaint Statement of Facts** **RE: Recall Y43 (NHTSA Campaign 22V-406) – Failure of Recall Remedy** **Summary:** The manufacturer (Stellantis/FCA) is refusing to provide a complete and effective remedy for **Recall Y43**. My 2022 Ram 3500 was manufactured without the **Particulate Matter (PM) Sensor**, a defect officially acknowledged in Recall Y43. This factory omission has caused terminal blockage of the **Diesel Particulate Filter (DPF)**—a specific consequential failure documented in the manufacturer's own recall filing. **Technical Argument:** 1. **Causal Link:** The official Y43 recall notice states: *"The PM sensor... may not have been installed... This could increase vehicle emissions and **block the diesel particulate filter**."* My vehicle currently suffers from the exact "blocked DPF" condition described. 2. **Ineffective Remedy:** Stellantis has offered to install the missing sensor (the Y43 part) but refuses to replace the ruined DPF. Installing a sensor on a filter already terminally blocked due to the sensor's absence is not an "effective remedy" under the **National Traffic and Motor Vehicle Safety Act**. 3. **Warranty Admission:** Per **TSB 09-014-22 (X97)**, the manufacturer has issued a 1-year unlimited mile warranty extension for the DPF specifically for vehicles affected by Y43. Refusing to replace a filter that failed *before* the recall was performed is an attempt to circumvent this warranty obligation. **Safety Risk:** The vehicle is currently in "Limp Mode" with a "Filter Full - Power Reduced" message. This creates an unreasonable safety risk of **stalling or loss of power** while operating on public highways, a condition explicitly mentioned in the Y43 safety report as increasing the risk of an accident. I am seeking an order for the manufacturer to replace the DPF as part of the Y43 recall remedy at no cost to the consumer. The manufacturer’s Case Manager has denied the claim and refused further communication

I own this truck and have had issues with the exhaust regeneration process for about 6 months. I have taken it to the dealer 3 times and they have done diagnostics and replaced the diesel particulate filter, but the issue continues to happen. They have now told me that the system is not reparable and they don't have support from RAM manufacturer to troubleshoot and repair this issue. They have multiple customers with the same issue with the diesel exhaust system not operating properly, hampering the engine performance, damaging the engine and exhaust system, polluting from the exhaust discharge. This is a widely known issue with the 2022 Ram 3500 from other owners, yet RAM refuses to properly address the issue. They advertise their trucks with certain horsepower and output specs, which aren't accurate due to their faulty exhaust systems. Consumers are now completely removing the factoring exhaust systems because they damage the engines and cost thousands of dollars to attempt to repair, which many times never work. This needs to be addressed with RAM and recalls put in place to address the failures with their exhaust systems. My truck has 28,000 miles on it, 3 years old, and is not operable. The dealer has had 3 attempts to repair this and is now turning me away. Please help! Thank you

Driver of the 2022 Ram 3500 pulled out of a driveway onto a street and ran over a pedestrian who was crossing in front of him. Driver states he did not see the pedestrian. I understand the 2022 Ram 3500 is equipped with front ParkSense Sensors, but these sensors failed to deploy. The pedestrian suffered very serious injuries requiring weeks of hospitalization and additional outpatient rehabilitation. The incident is caught on surveillance camera. The vehicle should be available for inspection upon request. The vehicle has not been inspected.

***1*** The emissions system on this truck (2022 Ram 3500 with 34,435 miles) has been problematic since I acquired it 5 months ago. It continually attempts to regenerate and rid itself of ash/soot buildup. If it does not successfully regenerate, it will go into a state of reduced power, also known as limp mode. The truck is available for inspection and will be at Lithia CDJR in Corpus Christi tomorrow, 07 Jan 2026. ***2*** Today specifically, the truck flashed a message EXHAUST FILTER NEARING FULL SAFELY DRIVE AT CONSISTENT SPEED TO CLEAR. I got on the highway to achieve this and avoid lights and stop/go traffic. It typically takes around 25 minutes of consistent driving for it to clear. But today, shortly after I reached highway speeds, the truck entered limp mode, displaying EXHAUST FILTER FULL REDUCED POWER SEE DEALER. This was a very alarming incident that created a bottleneck on the highway and presumably for me to nearly be rear ended as it happened at 5:35pm. I was able to safely make it off of the highway, however this incident has put the lives of all motorists on the road around me today in danger. ***3*** The truck has been inspected numerous times by the dealership. The Diesel Particulate Filter was replaced on 01 October 2025 (this was the first time the truck went into limp mode on me). The frequent regenerations continued after the DPF replacement and a sensor was replaced on 29 October 2025. Regens continue at approximately 1 per week. ***4*** This is a known issue amongst the community of RAM truck owners. It's unfortunate that many do not report it because the safety issue could easily set off a chain reaction, especially if this heavy duty truck were to be towing a heavy load as it capable of doing.

My pm sensors or particulate matter system malfunction and failed which lead to emissions issues and created my vehicle to drive in limp mode. Limp mode basically slowed downs the vehicle is slow as 5 mph as soon as this light displays at any time while driving on the highway. This put my safety in danger and the public as I transport what dot considers a type hazardous material. The sudden loss of power in the middle of the road has made vehicles around me extremely vulnerable to fatal collisions. I took my vehicle to the dealership where they confirmed this malfunction and problem with my vehicle but no recall has been issued as of yet no warning lamps appeared prior to the failure.

While driving on interstate leaving a construction zone started to accelerate to maybe 40mph and heard/felt a hard clang and lost all forward motion costed to side of interstate. Looked underneath truck, nothing visible broken or leaking. Restarted truck tried to move forward with no luck. Reverse worked, put back in drive loud noise again stomped on the accelerator and started moving forward very slow and difficult. Made it to an exit to look at things in a safer location than the busy interstate. Figured out that I had reverse and 5th gear so it was very hard/ slow to get moving. Check engine light on, gear ration incorrect, code P0731, Tran sensor failure, no 4x4 Transmission failure 1-4 gears not working

The transmission in my vehicle failed suddenly on May 31, 2025, entering “limp mode” and losing the ability to shift properly. The vehicle became immobile and was towed to the dealership. Initial diagnostics revealed difficulty shifting between 3rd and 4th gears. Service technicians attempted repair in June based on RAM TSB MC-10231775, which indicated snap ring failure in the Aisin transmission. Repairs prescribed in TSB were attempted but unsuccessful, as the vehicle still could not shift into 4th gear. Additional parts were ordered, and another repair was unsuccessfully attempted in late June. Ram has shipped a new transmission which we are waiting on the dealership to install.

My 2022 RAM 3500 has repeated failures of the diesel particulate filter (DPF) system. The truck enters limp mode unexpectedly, including while towing on the interstate, creating a serious safety hazard due to sudden loss of power. Since purchasing the vehicle, I have experienced ongoing issues with the emissions system, specifically related to the DPF. The check engine light comes on frequently, and diagnostic scans consistently show code P2459 (Diesel Particulate Filter Regeneration Frequency Too High). The DPF system has been replaced approximately five times by authorized RAM dealer. Despite these repairs, the same problem continues to occur. The truck will sometimes enter limp mode without warning, drastically reducing engine power. This has happened while towing a camper on the interstate, making it difficult or impossible to maintain safe highway speeds or accelerate when needed. This puts me, my passengers, and other motorists at risk of a crash, particularly when merging or changing lanes in fast-moving traffic. I have already pursued and settled a claim with Stellantis (RAM’s manufacturer) for $10k due to these issues. However, the problem persists, and the root cause has not been resolved. Accepting the settlement was recommended by legal counsel. The failure has occurred on multiple occasions (at least five separate incidents). The vehicle has undergone several service visits and emissions system replacements, but the safety issue continues. Current mileage 42,000. Dates of incidents from most recent: 6/25 (still in shop), 3/25, 9/24, 8/24,7/24,6/24,4/24,1/24,7/23,6/23,11/22. Documentation available upon request. Diesel particulate filter (DPF) system replaced approximately five times. I believe there is a defect in the design or operation of the emissions system that poses a safety risk. Loss of power while driving at highway speeds or towing creates a dangerous situation. I am reporting this in hopes that NHTSA will investigate this recurring issue.
