Upper rear control arm is connected to the subframe of the car and it's rotted/ rusted out where the bushing goes to hold the control arm in place. Where am I supposed to mount the bushing now since it's no longer there.
Noticed an issue in January 2010: took car to a auto-repair shop for repair; new tires and alignment service. On 03/22/2010 while leaving a shopping mall the vehicle lost control and veared a hard left into a cement light pole in the middle of the parking lot. (I was able to apply the brakes in time and turn the vehicle) only damage was to the front driver side bumper and quarter-panel, body damage only. I then tried to drive the vehicle which at that point operated in drivable condition. On my way to the auto-repair (less then 1 mile away) my vehicle completely broke down in the middle of an intersection in another shopping plaza. The car was then towed to the auto-repair shop, which then later called and explained that the frame of the car was cracked and the whieel was detatched. …

My son was in an accident in which someone pulled out of a side road into his path of travel. The front of the Hyundai from just past the grill on driver's side to entire passenger side hit the front driver wheel forward on the other car. Neither the steering wheel nor the passenger side airbag deployed in my Hyundai. He hit with such force the steering wheel was bowed and steering column was broken along with the bottom of the dash where his knees hit.
Tl* the contact owned a 2001 Hyundai Sonata. While driving at 55 MPH, the contact lost control of the vehicle and crashed into a bridge. The contact stated that the front driver side air bag failed to deploy. A police report was filed. The contact suffered injuries to the head, thumb, knees, neck, and chest that required medical attention. The vehicle was towed to a service lot. The vehicle was destroyed. The failure mileage was 134,000.

My car has a rear rust problem that has left the car undriveable. The support for the wheel has rusted through and the rear wheels are tilting in. I did lose control of the car as it swayed for one side of the road to the other lane and back. My speed was about 45 MPH on a two lane road with a spead limit of 45 to 55. When I would hit a bump in the road the car swerved uncontrolably the rust is a serious safety problem that our government is ignoring. I have had the front of the car in for the original recall for the front subframe. Did you know that this recall allows the mechanic to drill holes in the subframe to help the moister escape. Sounds like a temporary fix to a serious problem because the design did not allow for moisture problems. Yet the problem is road salt according to the original law suit. But then why drill holes if the moisture is coming from the outside. …
