NHTSA Complaint #11639305 — 2021 RAM 1500

I am submitting this report to alert the NHTSA of potential safety violations and undisclosed structural damage, drivetrain modifications, and possible engine replacement regarding my 2021 RAM 1500, which was purchased from Courtesy Chevrolet after being previously owned by Enterprise Rent-A-Car. Unreported Frame Damage & Structural Repairs Multiple inconsistent and unseen frame welds were discovered, indicating prior accident damage and unreported frame repair. Frame welds do not match factory precision welding, suggesting post-factory reinforcement or structural fixes. Undisclosed Transmission Swap from 8-Speed to 6-Speed According to NHTSA records and the vehicle’s VIN, my RAM 1500 was manufactured with an 8-speed transmission. After purchase, I discovered that the 8-speed had been swapped for an older 6-speed transmission (6HP70), which was never disclosed. This creates potential drivability and safety concerns, as the truck’s ECU may not be calibrated for the correct transmission. Possible Undisclosed Engine Swap The engine in my truck has multiple ink and paint markings, which are commonly seen on replacement engines. RFID engine label does not provide a matching serial number, making it difficult to confirm if the engine is original. The casting number on the engine sticker is inconsistent with the vehicle’s model year and VIN (2021), raising concerns that it may be from an older model. Engine mount bolts and wiring appear disturbed, suggesting prior removal and reinstallation. If my truck has an older or higher-mileage engine, this impacts performance, emissions compliance, warranty status, and safety. Lack of Maintenance Records & Vehicle History Transparency
