Model years: 2021, 2022
Problem: Chrysler (FCA US, LLC) (Stellantis) is recalling certain 2021-2022 Ram ProMaster vehicles.

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.
Fix: 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.

Problem: Chrysler (FCA US LLC) is recalling certain model year 2015-2016 Ram ProMaster City vans manufactured September 26, 2014, to March 5, 2016. A low-voltage electrical harness connector by the front driver seat may be susceptible to water intrusion and corrosion.
