“Bought new car August 16th 2024. Few days later, I was turning left at a light and the car lost power as I was turning and error messages came up on the dash screen saying service transmission. I also observed that the cars gear indicator went to Park by itself even though the car was still moving. Pushed the engine start button and car came back on and I switched the gear to Drive. Took car in on the 19th to get looked at. …”

NHTSA complaint #11722117, filed 2026-03“I was leaving work when my car had trouble accelerating from stop. The engine revved, but the gear would not engage. It happened several more times after I stopped at a light or slowed to get on the highway. It would take a minute or so to engage, and then I could drive the car, but it made it dangerous when trying to merge on to the highway or to make any turns in to traffic. It then happened two more times as I slowed to make turns until my engine light came on as I was turning on to my street. …”

Had this happened 2 min prior while at highway speeds in crowded conditions, I can only imagine how many injuries could have occurred. My vehicle had 3800 miles on it.
