2022 Ram ProMaster Complaint Log

Van brakes unexpectedly causing loss of control of vehicle for up to 5 seconds. Cannot accelerate when this occurs. While entering a major highway and accelerating, the van braked on its own and would not accelerate causing a semi to almost run into the back end of the van. The braking happens frequently and without warning. There is no rhyme or reason as to when it will occur as in road conditions, speed, curves, weather, etc. Took to Lithia dealership in Billings, MT four times and the problem still has not been resolved. 10 Aug 2022: Lithia could not verify the forward collision error. 1 May 2023: Lithia pulled code C14A5 sensor blinded and ordered new camera. 7 July 2023: Lithia pulled code B1006-49 internal electronic failure, removed and replaced the FFCM and calibrated the camera. 25 Sep 2023: Lithia pulled code C14A5-92 sensor blinded and the FFCM was recalibrated Turned Forward Collision off but the unexpected braking still occurs. This issue has been ongoing ever since I purchased the van in July 2022. This is an extreme safety issue as I have absolutely NO CONTROL over the van when the forward collision takes over.

The contact owns a 2022 Ram Promaster 1500. The contact stated while driving 30 MPH, another vehicle overtook his vehicle and the vehicle experienced phantom braking. The Forward Collision Avoidance warning light was illuminated. Additionally, the contact stated that the odometer indicated that he was driving 15 MPH while he was driving 60 MPH. The vehicle was taken to an unknown dealer who could not duplicate the failure. The vehicle was then taken to a second dealer where it was diagnosed that the Forward Collision Avoidance camera needed to be recalibrated. The contact was informed that the cracked windshield needed to be replaced. The dealer was awaiting the part to replace the windshield. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was approximately 30,000.
