“I was driving and rusted subframe collapsed control arm & right axel broke also power steering belt broke. I was able to get over nearly having an accident. I had my car repaired in 2010 as per recall yet I tried to push for sub frame replacement over repair at that time with no luck. I believe these sub frames that were repaired should be replaced. This is an extremely dangerous situation I could have been killed!”

NHTSA complaint #10306220, filed 2010-02, 91,000 miles“I own a 2004 Hyundai xg350l that is having accelerator issues. On several occasions, while stopped / idling, or slowing down, the vehicle will suddenly accelerate. This is while the brake is being applied. I can be setting at a stop light or stop sign with foot on the brake, not the accelerator, ( I do not drive with both feet like some people incorrectly do : ) and suddenly the car will rev up and try and accelerate forward. In other cases, I can be slowing down with brake applied, and again, the vehicle will accelerate forward. …”
NHTSA complaint #10554931, filed 2013-12, 89,000 miles“When slowing down and braking the car accelerated on its own. The first time I hit the car in front of me . I had to turn the key off to get it to stop. I had bumper damage. Have had the car in 5 times for this same problem. Each time the dealer said they can find nothing wrong. The last time the factory rep checked it and said he could do nothing because it would not do it then. As of 4/20/06 this car has done this 8 times. It is like driving a time bomb.”
NHTSA complaint #10155765, filed 2006-04, 3,629 miles“Hyundai XG350 year 2004 model had unintended acceleration problem. The car jumped the curb when pulling into a parking spot. My foot was on the brake as evidence by my daughter. I tried to break numerous times, and finally the car got caught up on a bush. It was as if the gas pedal was stuck. The car just would not stop, and it was slightly damaged. Hyundai replaced the car, but rewrote the loan with the 10 k original down payment getting lost in the paperwork. Reporting this because I did not know of this forum back then. …”
