I have been submitting reports to you for several months with no resolution. The truck yet again experienced the same problem, twice, within 1 week. It would start but then claim that it couldn't detect what gear it was in and said "can't shut off until transmission is in park". After cutting electrical power to get it to shut off, it would not start. After getting it started, it would not go into gear. Once I got the engine running and transmission to go into gear, it no longer had ABS.

The truck had about 7400 miles on it. It gave a warning that the DPF was near full and take it to dealer, about 20 minutes late it said DPF full power reduced. Two days later it cleared that code and began flashing the turn signal intermittently and giving warnings that the trailer brakes were not working, then that the tailgate was down. Shortly after that the instrument cluster went completely blank. I was driving it to the dealer when it ran out of fuel and forced me to stop on the highway. The vehicle has been at the dealer for almost 4 months now. When they replaced the dash cluster it would take too long to start. They replaced multiple modules and I believe three dash clusters before declaring it repaired. I picked it up for a test drive and the frontal collision warning came on intermittently along with a warning that automatic wipers would not work. I took it back. While at the dealership they reported to me that it developed additional issues and would not shift into gear. It is still at the dealership in Pine Bluff AR.

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.

### **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

Upon arriving to the residence, the vehicle was scanned, and it was determined that the turbo charger actuator had failed and needed to be replaced.

While entering the interstate highway and accelerating to merge into traffic the transmission would not shift properly and check engine light came with code p0871. I could not fully control the speed to keep up with traffic due to the erratic shifting of the transmission and was nearly rear ended by another vehicle also merging into traffic. This could have caused a multi vehicle accident at highway speed of 65 MPH. The p0871 code is transmission fluid pressure sensor / switch c circuit range/performance. There have been previous recalls with this transmission for the same problem but my vin was not listed. Transmission would not shift properly until code is reset with scan tool.

Trucks DEF Gauge malfunctioning goes from full, to half, to full, to empty, and then warns about going into limp mode. Filled with DEF and still doing it. Took in for repairs, company said they fixed it, but within 3 miles gauge was doing the same thing. This is a hazard as it will put the truck in limp mode. Known issue with many complaints, needs fixed

***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.
