I am writing to express my concern about vehicle warranty coverage being provided by RAM (Stellantis NA) on their vehicles. I have a 2021 Ram 1500 which has a motor generator unit (MGU) which has failed due to a defect with the bearings. This has been diagnosed by the dealership and identified as covered under the emissions warranty. This diagnosis was made by Kolosso Ram in Appleton, Wisconsin in June of 2026. At this time I was advised that it could be a 6 to 8 month wait…

In January I experienced a “backlite leak” that allowed water to enter the cab of my vehicle. As a direct result of this water intrusion, my RFH (Radio Frequency Hub) module failed due to electrical shorting caused by moisture exposure. This failure was sudden and completely outside of my control and was not the result of misuse, neglect, or normal wear and tear. Not to mention the risk it put my family in as I was driving with my wife and daughter when the module failed and…

[XXX] Fire occurred while driving [XXX] my Ram 2021 and it was like a mini blast with a lot of sparks as I saw in a rear-view mirror. Everything went out on the dashboard and the car stopped at the Top of Wolf Creek Pass [XXX] . I got out of the car and saw a small fire burning under the car. The fire under the car went out on its own. The very shape of the hole (perfectly round) in my muffler indicates an explosion that occurred simultaneously. Also, the fused edges of the…
