2022 Ram ProMaster Driver Assist & ADAS Problems

The fcw/acc stopped working all possible fixes exhausted left turn signal intermittent failure. The fcw/acc started as intermittent but now doesn't function at all seems to be common issue from research. There were warning lights indicating an issue. Van was at a dodge dealer for fuel and other electrical issues

The contact owns a 2022 Ram Promaster 3500. The contact stated while driving at approximately 45 MPH, the Forward Collision Avoidance warning illuminated. The contact stated that the vehicle was driven however, the Forward Collision Avoidance safety feature was disabled. The contact had taken the vehicle to a local dealer, where it was diagnosed that the Forward Collision Avoidance system was not functioning properly; however, the dealer was unable to repair the vehicle. The manufacturer was informed of the failure. The failure mileage was 7,363.

Forward Collision Warning ("FCW") shuts down during vehicle operation, FCW Off dash warning light comes on, dash message system indicates FCW system restarting a couple of times, and then messages FCW unable to start, take unit to the dealer for servicing. This happens about every other time vehicle is started. Vehicle taken into local dealer twice, the last being on May 22, 2023, where dealer confirmed it was able to reproduce problem. From repair invoice: " 2960 NEEDS FORWARD FACING CAMERA FOR HALF CAMERA FAULT Cl4A5-92. SENSOR BLINDED BUT CANNOT REPLACE DUE TO CHRYSLER CALIBRATION PROCEDURE CURRENTLY UNAVAILABLE AT THIS TIME." I purchased unit brand new, 59 miles on odometer. FCW turning off has happened intermittently since I purchased (February 2023). I reached out to the manufacturer, FCA LLC, last month via e-mail and they could not provide and expected date replacement/repair parts will be available. My assigned service advisor at the local dealer no longer returns my calls or e-mails on when part will be available. Please note other 2022-23 Promaster owners have the same forward collision warning problem too.

While using adaptive cruise control and traffic sign assist, the vehicle has a feature called intelligent speed assist. It is supposed to detect new speed limits signs and ask the user if they want to adjust their set speed. Instead, the feature automatically changes the set speed without user input. For example, you are going down the highway with adaptive cruise control set to 75 mph. The vehicle erroneously picks up a lower speed limit of 45 mph (could be for feeder road, highway exit speed, or old construction sign, etc...). Within a few seconds the vehicle begins to aggressively brake on the highway in order to reach the lower speed limit. This is very dangerous as it is a surprise to the driver and could result in a collision.

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.
