The car was pulling to the right and thought I needed a wheel alignment but after coming back from taking my children to school the car stopped in front of my house and started making a rattling sound when I put it in gear (reverse and drive ) I thought is was axle that may have slipped out of place. The car was taken to mechanic who said I had a lot of rust and a whole in my frame and the rust started to fall off the car frame. I called the consume affairs dept for Hyundai and they picked up the car and took it to a Hyundai dealership to hopefully get fixed. They wanted to charge me $2,100. 00 for the repairs.

Driving 2001 Sonata car was swaying on road when going on turns was not working with steering in timely manner. Had mechanic look at to see what was wrong. He found on passengers side of car the lower frame rusted from inside out where the lower control arm attaches and is now only semi attached so the assembly moves around. There is a huge hole in frame. Car is no longer safe to drive as whole assembly will fall off. As you can see car is only 7 years old. This is unacceptable car only has 111000. Miles on it. The car is in my driveway has not been taken apart all parts are original not sure what to do. Can't be driven as is. I noticed other complaints of same nature I don't consider this condition acceptable in a 7 year old car frames should last many more years.

My 2001 Hyundai Sonata's subframe rusted to the point of where there were 7 in" holes completely through- this caused the lower swing arm to detach from the frame and subsequently the vehicle suspension failed. This occurred while my two children were in the car. Both front tires were damaged. Dealer did not replace tires, did not pay for towing or alternate transportation- gary rome Hyundai, holyoke MA.

9 Frame Rust problem

Failure Date: 08/05/2008

Tuesday, August 5, 2008, I brought in my 2001 GLS v6 Hyundai Sonata to balise Hyundai of cape cod in hyannis, MA. My car had approximately 166,500 miles on it at this time. I was looking to get a throttle position sensor replaced. During their diagnostics, with the car on a lift, they noticed two things. One, a power steering leak was occurring most likely because of a corroded power steering line near the passenger side of the subframe. Two, in the immediate area of the suspected hose failure, the subframe had rusted through on two sides of the piece. The main hole in the subframe is fist-size or larger and the second is not good. I was informed that the subframe issue was a major safety hazard and warned me of what could happened should it fail. They also told me about the difficulties that replacing it could bring. They told that they were highly uncomfortable with me driving off the lot with the car with the subframe in that condition because it could go at any time. When they gave me an estimate for repairs to my car, they informed me that they might do the service on the subframe for free. They had to get approval from a regional rep or such person. However, as of today, Sunday, August 10, I have not heard back from the dealer. Today, I decided to do some research into replacing the subframe and finding the part. When I did a yahoo! search for "sonata subframe", I came across the NHTSA investigation into this problem. I, thankfully, have not had a failure or accident because of this condition, yet.

10 Frame Rust problem

Failure Date: 08/01/2008

Took automobile for routine maintenance. Mechanic discovered major rusting on subframe and engine cradle. Rusted through and has been described as extremely dangerous.

11 Frame Rust problem

Failure Date: 05/19/2008

Passenger side subframe rusted through and created a severe safety problem. My mechanics noticed it doing some work on my car. This must be addressed and something done before people are killed when these frames break. I was lucky it was discovered, because there is no warning lights for this. . . And can not be seen except if car is on a lift.

12 Frame Rust problem

Failure Date: 05/01/2008

While rounding a gradual curve at approximately 50mph suddenly lost steering control and went off road. Examination of vehicle subsequent to the accident revealed loss of control caused by severely rusted right (passenger side) front subframe and approximately 8 inch hole and bending/cracking of such due to the rust, this on a vehicle which is otherwise pristine (there is absolutely no rust elsewhere on the vehicle). I urge NHTSA to require Hyundai to address what I have now learned is a very common problem with the model in question, especially before any other lives are put in jeopardy or lost due to what is clearly and obviously a gross manufacturing and/or design defect. Note that I consider the situation to constitute no less than an emergency and that until certain model years of the Hyundai Sonata are updated with a revised/new subframe they should not be driven and indeed are not safe to be driven. At present my vehicle is no longer road worthy due to the rusted subframe and as it is 4 months out of warranty (warranty pertaining to rust through) I foresee that I will have to bear the expense of the repair (subframe replacement) myself.

13 Frame Rust problem

Failure Date: 01/23/2008

Front right portion of front subframe is rusted and broken. Alignment and steering is way off . Was advised not to drive since frame damage is extremely dangerous.

14 Frame Rust problem

Failure Date: 09/28/2007

2000 Hyundai Sonata with a defective sub frame. Consumer would like to be reimbursed for expenses on the repair of the sub-frame. He also believes that Hyundai needs to put out a recall on them and get them fixed due to concerns with the sub-frame. The consumer stated as he was driving, the lower control arm of the front passenger wheel disconnected from the vehicle which caused him to slide to an immediate halt. The cause of the failure was due to a poorly designed frame which rusted and rotted so badly that the control arm had fallen off the frame, the axle ripped from the transmission and the wheel had slammed into the wheel housing and quarter panel. The insurance company declared the vehicle a total loss due to the extent of the damage prior to the frame damage, the consumer experienced a flat tire which was due to excessive wear on the inside of tire.
