About These NHTSA Complaints:
The NHTSA is the US gov't agency tasked with vehicle safety. Complaints can be spread across multiple & redundant categories, & are not organized by problem. See the Back button — blue bar at the very top of the page — to explore more.
The car started losing speed and stalled a couple of times. The camshaft sensor and crankshaft sensors were replaced. The problem happened 6 months later.

Backing into the garage, my foot on brake, the engine suddenly revved to high RPM, the car shot backwards, propelling a heavy rubber mat on which the car is normally parked out of the garage and into the driveway. The vehicle then impacted and crashed through the rear garage wall before coming to a stop. I managed to pry the gear lever out of reverse, hit drive instead and sent the car, wheels still spinning and laying down rubber, forward out of the garage. On its way out the car swiped along the right side the garage door post before finally coming to a stop in the driveway. Final result, serious damage to both the car and the garage. Fortunately this did not occur in traffic or with pedestrians in the area. On-line research has since shown me that there have been numerous other similar incidents where Hyundai Sonatas have suddenly accelerated on their own. See
