The contact owns a 2022 Ram 3500. The contact stated that while driving at an undisclosed speed, the engine made abnormal knocking and ticking sounds. The knocking and ticking sounds became louder while accelerating. There was no warning light illuminated. The vehicle was taken to an independent mechanic, who determined that the piston had ingested the grid heater nut. The mechanic replaced the piston, cylinder head assembly, gaskets, rod, gasket intake, Hamilton flat tappet conversion kit, and XDP grid heater. The manufacturer was made aware of the failure. The failure mileage was 88,745.

### **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

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

The contact owns a 2022 Ram 3500. The contact stated that while driving approximately 10-15 MPH, there was an abnormal rattling sound coming from the vehicle. The engine warning light was illuminated. The local dealer was contacted, and it was determined that the grid heater bolt had melted and fallen into the engine. The vehicle was repaired after two months due to the piston being on backorder. The manufacturer was contacted, but no additional assistance was provided. The approximate failure mileage was 35,000. The VIN was not available.

***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.

The # 4 cam bearing seized to the camshaft. Upon further investigation the #4 main bearing was damaged from metal chips that were not removed during the manufacture of the engine. This damage from the manufacturing defect left the engine block damaged beyond repair. So a short block was ordered and installed.

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.
