Driver assistance reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

12/2020 First the TPS sensor failed at 1,000 miles and almost caused an accident. Would not go over 25mph, was shifting hard, and the service engine light was on. Verified and replaced at dealership. Second, the rear view camera stopped working while backing up and almost caused an accident - no back windows - major safety issue. Replaced by me as they have no replacement for it even though its under recall. No warnings. Third, the transmission was shifting hard and fell out while I was driving on the freeway at 55,000. Damaged transmission and crankshaft and joints. Verified and replaced at dealership. No warnings, no lights Fourth, the transmission bolt was found loose, hard shifts, and has an internal breakdown at 71,000 miles. Verified first by independent shop - they tightened the bolt for me and is now sitting at the dealership waiting on another transmission that has been verified and approved under warranty. No warnings, no lights

My 2021 Ram ProMaster 2500 has two open safety recalls with no remedy available: NHTSA Recall 25V-552 (rearview camera FMVSS 111 compliance issue) issued August 26, 2025 NHTSA Recall 25V-720 (cooling fan fire risk) issued October 23, 2025 As of April 2026, no remedy has been provided for either recall. The vehicle is used commercially for rental income, and the lack of a repair has caused financial loss of approximately $500–$1,000 per month. One of the recalls involves a potential vehicle fire risk. The prolonged delay without a remedy is concerning for both safety and financial reasons.

I had to replace my backup camera as it was faulty and the newer models had a recall. My blind spot monitoring system cuts off randomly going down the road. We have paid out of pocket for a new camera and the dealership can't figure out why the blind spot indicator cuts off.

The blind spot monitoring function frequently disables while driving this vehicle. This occurs more often during warmer weather and in my case only seems to happen when the brakes are applied. For a few minutes after each "blind spot disabled" warning, you cannot reset the blind spot alert function through the touchscreen system. This is a safety issue because you often don't notice that the blind spot alert is disabled and expect to see or hear the blind spot warning when driving if an approaching vehicle is in your blind spot. This issue seems to primarily affect 2021 Ram Promaster vans. There are many posts in the ram promaster online forum about it @ [XXX] . My dealer connected my promaster to their computer just after the disable warning and there was no indication that it had happened--even though you could visually see that the blind spot monitor was off in the vehicle touchscreen monitor. They kept the vehicle for an afternoon and could not determine what was causing this malfunction. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
