Example complaints
Body and structure: “1999 Hyundai Sonata Gls failed pa state inspection due to a rusted k frame ( frame that supports front suspension & motor). This is a 9 year old car original owner with 205,000. This should not have happened on a 9 year old car from pa. We want to know if there were other complaints from sonata owners with the same problem. As I said, this should not be happening.”
NHTSA complaint #10235067, filed 2008-07, 205,000 milesSuspension: “Driving at a low speed the passenger side front wheel suspension broke leaving wheel hanging and inoperable. Could not move car out of traffic lane. Upon inspection by the repair facility it was determined that rust to the sub frame and related bolts caused the failure. I was lucky that I was not driving faster.”

At that time the o2 sensor had went bad so that was replaced and we were also advised that it was way past due on transmission fluid which was their fault so they replaced that as well. A few months went by and the same thing happened again. These were once replaced again on the opposite side of the car. …”

If my foot was not pushed down on the brake I would have hit the car in front, it will also occur while in park with the engine rpms going up to 3200 and down to 1500 like it was a hunt lasting several minutes. It will stop ,but I can't figure out how or why. It seems to be worse when driving at sustained higher speeds on interstate, then getting off the exit. …”
