NHTSA Complaint #11713693 — 2021 RAM 1500

There have been several instances where the vehicle appears to lose traction in 4WD. An error message appears "4WD Overheated Performance Temporarily Reduced". When this message appears, the vehicle is unable to gain traction in snow. Even 1" - 2" of snow is enough to prevent forward movement. In this condition, the rear end of the truck tends to fishtail to the right and left. After checking online, there appears to be many other instances associated with this condition. The dealer replaced the fluid in the differential and transfer case hoping to fix the issue, but the problem persisted. They were unable to reproduce the issue on the second service call. Currently, my vehicle in in the driveway and is unable to move given the 1" of snow present. The truck is being towed to the dealer tomorrow, Jan. 28th, 2026, for them to assess it a third time. I believe the failure is related to the light duty Transfer Case & Transfer Case Motor, but that has not yet been determined by the dealer. I'm having the vehicle towed since losing traction on a slippery road can be dangerous and cause the vehicle to slow/stop and/or lose control along with 4WD.
