Typical electrical symptoms owners report

  • The blind spot monitor spontaneously disables itself, sometimes for hours or days, with dealers unable to consistently replicate the fault.
  • A battery-related fire produced heavy white smoke inside a towed RV, prompting a fire department response.
  • Headlights were reported to provide inadequate illumination at night with no warning light displayed, and the issue went undiagnosed by the dealer.
  • An awning deployed unexpectedly upon engine startup despite a prior recall repair, creating an injury risk.
  • A loose ground wire tied to an unrepaired recall caused the ABS and ESC warning lights to illuminate and nearly caused a crash.
  • A solar panel mounted on the RV roof detached and hung by its electrical connector until another motorist flagged it down.

    Exterior lighting

    Chrysler (FCA US, LLC) (Stellantis) is recalling certain 2021-2022 Ram ProMaster vehicles. The wiring harness may have a poor connection, which can cause the left taillight and left turn signal to become inoperative. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."

    Risk: 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 scenarios can increase the risk of a crash.

    Remedy: Dealers will inspect and replace the harness, as necessary free of charge. Owner notification letters were mailed February 20, 2025. Owners may contact FCA US, LLC customer service at 1-800-853-1403. FCA US, LLC's number for this recall is 21B.
