Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints 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.

reports

From owner reports, verbatim

Vehicle had a low tire, vehicle indicated it needed to be driven for recalibration of the sensor(s). Took vehicle for short drive up two lane road. Turned around and headed back to where was staying and upon acceleration the vehicle seemed to have pulled off the road but come to find out it didn't at all go off the right side of the roadway. The vehicle sort of jerked and went to the left, causing me to travel over the opposite lane and into the ditch on opposite side of the road, then when pulling out of the ditch the vehicle flipped and overturned skidding on it's top side along the roadway. There was a vehicle coming, they were able to slow but were still impacted by the car as it traveled on it's roof. The vehicle finally came to a stop. After exiting the vehicle, being able to ensure everyone was ok, it was clear the lower control arm on the driver's side was broken in half and that was what had caused the "jerking" and when it seemed like vehicle initially had gone off the right side of the road when it hadn't at all-it was a mechanical malfunction.
