### **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

On 01/21/2026 there was a warning light that came on stating accelerator control sensor, the next morning the truck started stalling, and continued stalling multiple times. I attempted to get the vehicle to the service center. It then stalled 2 more times, the service center told me they couldn’t look at the truck until the next day, the vehicle then stalled on me again that evening, they kept the truck until Friday evening, and told me they couldn’t duplicate the issue. They knew it had happened, but they couldn’t find the cause without replacing a bunch of parts until they found the correct issue. I took the vehicle home, started it the next morning and the maintenance required issue again returned, I took it back to the service center, they checked the codes, and told me it shows the 3rd taillight is staying on which indicates usually a fuel issue. They then sent me a quote stating a bunch of things that’s already been done to the vehicle outside of their service center, as well as the part they told me was where they had started to diagnose the issue and it didn’t work, all of which are not covered under the current warranties of the vehicle and basically the way I understood it that I would have to keep buying parts and replacing things out of pocket until the drivetrain issues were resolved.
