Plain-English summary
Chrysler (Stellantis) is recalling certain 2021 and 2022 RAM ProMaster vehicles. A poor connection in the wiring harness can cause the left taillight and left turn signal to become inoperative. These vehicles fail to comply with Federal Motor Vehicle Safety Standard number 108 (Lamps, Reflective Devices, and Associated Equipment).
An inoperative left turn signal may not notify other drivers of a turning vehicle, and an inoperative left taillight can reduce the vehicle's visibility to other drivers. Both conditions can increase the risk of a crash.
A total of 12,375 vehicles are potentially affected. Owner notification letters were mailed on February 20, 2025. Owners should contact their dealer or FCA US, LLC customer service at 1-800-853-1403 to schedule a free inspection and replacement of the harness. Additional information is available at www.nhtsa.gov or by calling the NHTSA Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153).
