Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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. …”

NHTSA complaint #11736324, filed 2026-05

“While driving on a straight highway, no wind, no weather, 65 mph, both hands on wheel, the van started revving and lost power. I pulled over with engine still running. There were no codes or warning light. I tried to drive again. It continued to rev and not get up to speed. I pulled over again and shut it down. I waited a few minutes and then started it. When pulling back on freeway it ran normal with no more issues for another 700 miles. I took it in to the Dodge dealer on 1-13-23 to have it checked. They couldn't find anything. …”
