2022 Ram 3500: sudden loss of power

Filed Mar 23, 2026 · Engine · TX

### **the federal safety agency Complaint Statement of Facts** **RE: Recall Y43 (the federal safety agency 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

***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.

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 the federal safety agency will investigate this recurring issue.

On 9 September, while driving, I got an emergency dashboard notice that stated Throttle System Malfunction contact dealer. It went out and then another immediately flashed that stated Exhaust System Malfunction contact dealer. The vehicle lost power within seconds after the second notice. I coasted to a stop on the side of the road. Once stopped, smoke quickly started coming out of the engine compartment and then flames. I contacted 911, an engine arrived but the truck was fully engaged and completely burnt.

I was driving coming to a stop for a red light and it turns green. As I go to press on the gas my dashboard lights up with error codes stating a 4WD System error of some kind. As I go to press on the gas the truck loses power and acceleration and starts making a horrible clunking noise. I took it to the dealer because it seems like a transmission issue. This is a 2022 Ram 3500 with 9300 miles at time of failure. I would hate to see what happens if I was towing a large load to lose power all of a sudden risking my life and others around me. Based on what I have researched it seems like a K1 Snap Ring issue to the T. Waiting on the "official" diagnosis from the dealer.

When pulling onto the interstate on ramp (45 mph) the truck attempted to shift up when all transmission power failed. The engine ran fine, just no power. I was able to safely pull to the shoulder and park . s Shifting from drive to neutral to park and back to drive still did not resolve the issue. I put the truck in park and shut off the engine . The transmission fluid temp, color and level was ok. I restarted the truck and shifted to reverse with no problem then to neutral and drive. It felt that the transmission engaged and I slowly crept forward. I slowly accelerated and was able to resume speed. No subsequent loss of power has been encountered, BUT the truck now has slippage from 1st to 2nd gear and occasionally 3rd. Had I been on the interstate this has a potential for serious accident incident. This is the first time this has happened. I had bought the truck used and certified from the dealer in Pennsylvania. There is currently 28k miles on the truck. There were and still no warning or codes to indicate a problem This occurred [XXX] 2024. No dealer, tech or shop has looked at this issue.

-What component or system failed or malfunctioned, and is it available for inspection upon request? A: Transmission -How was your safety or the safety of others put at risk? A: I was never contacted by RAM regarding the possibility of a catastrophic power loss c/o transmission failure for my RAM truck. While driving E/B on Interstate 15 in the # 2 lane at highway speeds and going up a grade, the vehicle suffered complete forward momentum loss and only engine revving was occurring, while losing forward momentum & speed. I had to negotiate several, extremely busy/heavy traffic tractor-trailer filled traffic lanes to make it to the emergency shoulder of the roadway before losing all forward momentum and miraculously did not have a collision with high-speed heavy traffic. -Has the problem been reproduced or confirmed by a dealer or independent service center? A: I took my RAM to a nearby dealership. Based upon my description of the event and their subsequent vehicle inspection it was revealed and confirmed that somehow my RAM was erroneously, or purposely circumvented from the current transmission failure recall. The dealership discovered the issue with my transmission failure was identical to an in-progress the federal safety agency bulletin: 71A with TSB 21-00-2-23 (Attached PDF) and subsequently performed the repair free of charge. -Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? A: No, it was inspected and serviced by only by an authorized dealership and none of the above. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? A: Yes, the lights activated instantly/simultaneously as the failure was in-progress, in heavy traffic on the interstate.

I have had two catastrophic failures of the Clutch Snap Ring that the first time left me and my children stranded on a highway 800 miles from home and took 31 days to repair. The second failure was while driving and almost caused me to be hit because of the sudden loss of power. This is a known failure that is reported in Service Bulletin (21-002-23) filed with the federal safety agency. The original dealer reported he had seen 3 cases of these failures and the second dealer has told me he has 4 trucks waiting for this repair. It is a major safety issue that is known but not being resolved.
