The immediate symptoms of the problem have been reported to include: "suspension failure, partial or complete wheel detachment, steering anomaly, and/or sudden vehicle disablement," according to the NHTSA summary of the complaints. Several of the failures have occurred in traffic, although the majority were discovered during mechanics' inspections.
Buyers of Sonatas with model years 1999 through 2002 have reported 'fist'-sized holes in the frame according to the NHTSA website. The problem either is more prevalent among the earlier cars, or takes several years to manifest. Of the 40 complaints received by the NHTSA, 19 are for 1999 models, 16 for 2000 models, 3 for 2001 models and 2 for 2002 models.
The focus seems to be on the right side of the frame, especially the right rear corner where the suspension mounts attach. Some reports note the engine cradle, cross-member or front sub-frame, however, so it does not appear to be exclusively localized to the suspension mounts.
A contributing factor is likely the addition of road salt, since 35 of the 40 complaints originate from the so-called 'salt belt' of northern states that have severe winters.

If you own a 1999-2001 Hyundai Sonata I suggest inspecting your subframe for rust. If you are not sure where to look, you should turn your steering wheel all the way to the right. Look where the A-Arm bolts to the frame. You will probably find severe rust. If you do, I would like to hear from you at tntnknbjuno.com Even if it has not failed yet, I suggest taking it to a Hyundai dealer and filing a claim with Hyundai Consumer affairs.
My hope is that Hyundai, who has admitted to a problem by paying for repairs will soon address this obvious safety issue.

"I have a 2000 Hyundai sonata, the right side sub frame is broken in half! I am so upset because I love my car. I found out to replace the sub frame is $900!! I don’t know what to do. Should I go to a hyundai dealer and ask if they will replace it? I was not aware till now that it happens alot."
Well of course you should take it to your Hyundai dealer Jessica. Did you not read the previous comments on this same page? Hyundai has apparently served their customers quite well on this matter.

Hyundai simply said to buy a new subframe, which comes to nearly $2,000. I am merely a college student at Xavier University and could not afford such a repair, which of course, was not covered under warranty. I found a mechanic who was able to locate only one sub frame in the entire state of Ohio at a junkyard that he replaced mine with...the job cost me about $1,600.
Is there actually a way to receive reimbursement for this mess? I heard about the Toyota Tecumseh mess, and their buy back deal...what can I do?? Please e-mail me if there is an answer, that bill was devestating.

I have given this car all required oil changes etc and other required maintenance services on time for the 8 years I’ve owned it. I am the original owner.
Any routine examination of the car would have shown this corrosion, but I was not informed of this problem until I had a serious incident.
According to Hyundai, the part was on back order, and they found an excuse not to give me a loaner car and are seemingly balking about paying for a rental car. Hyundai Consumer Affairs has stated that I would be contacted by a Regional Representative within 3-5 business days. I contacted Hyundai Consumer Affairs and the Hyundai Dealer almost every day looking for status. They have told me everything from they are trying to locate the part at their plant in Alabama to they have spoken to several Parts Managers who are trying to expedite delivery.
It took 3 weeks, but Hyundai fixed the car and also paid for the car rental. They know the problem exists. Dealing with the Eastern Regional Rep in Atlanta was the best thing I could have done.
I was very lucky that I was not on a main highway when it happened as I could have been seriously hurt or killed.

they should pay for it - but will they - I am not looking forward to those phone calls - any advice will be greatly appreciated

I took my car into the dealer this evening.
I did not mention anything about what I know. I simply told him while replacing the rotors i noticed the arm to the right front tire- he interupted and said " the frame is rusted out right. He said they will replace the complete sub-frame at no cost. He also said they will inspect all components connected to the sub frame.
I'll be interested to see what they come up with.
They refused to pay for a rental car. I did not push this issue as the car is not needed, and I was pleased that they came right out and acknowledged the problem and promised the fix.
I will say I am displeased they did not mention this problem a year ago when they repaired my driver side wheel bearing. They also told me I needed rear control arms, so I'll be interested to see if they find rust in the rear end also.
I will file a report with the NHTSA, once all the facts are in.
I live in Central ohio.

My wife drives a 2002 Hyundai Sonata GLS with a little over 60,000 miles on it. She noticed the tires squeeled easily when turning a corner, so I took it for a test drive. The car was shifting all over the road. I needed tires,so I had Firestone take a look while I discussed tires with them and found that the right side of the front frame was almost rusted away. The entire steering assembly on the right side was shifting and flexing with the frame that was nearly rusted away. I called the dealer immediately and took it in the next day. They knew of the problem and said it was covered under warrantee. They also found a tierod had rubbed against the frame due to the rust and replacing it. It will only take a couple days and should be ready tomorrow, but they declined a free rental car during this time. I am very amazed that there was no recall on this, especially with the high possibility of death or injury from an accident should it fail while driving. We were lucky that didn't happen! I am happy they are fixing it, but very upset we were not notified of the problem. I think Hyundai is negligent of not disclosing the problem. I sure hope nobody gets seriously injured. I live in Columbs Ohio.

I'm in Columbus also, Mine is currently at the Hatfield dealership, I'm going to call them tomorrow and find out what the full extent of the damage is. They estimated it would be a week and a half.
The class action on mine was settled years ago, I think I got a year or two of free road side service.
Kyle Posted: 8/28/2008 9:53pm PDT
I took mine to Denise Hyundai on morse road because it is closer to me here in Westerville, but I originally bought the Hyundai at Hatfield. Denise fixed it in two days along with a tierod and power antenna that was broke. All under warrantee and no charge. At least that is what they said, but stilll waiting for the paperwork in the mail. We picked up the car yesterday and seems ok, but I need to take a closer look. I worked with a service guy by the name of Jim, so maybe he can help you. They had a couple frames in stock when I was there. I didn't hear anything about a settlement or any free road side service, but maybe that is because we purchase the extended warantee that gives up 10 years 100000 miles bumper to bumper. Hope yours works out.
Bob Schilling Posted: 8/30/2008 8:23am PDT
I talked to my dealer yesturday and they have not totally accessed the damage, they will do that once they start working on the front sub frame, which is all they think is rusted at this point. They assured me they will inspect the rear sub frame and all components.
Did they replace the rear sub frame on yours? I'm concerned if they don't do the rear, it will rust out in the near future.
kyle Posted: 9/8/2008 11:43am PDT
I replaced only the front sub frame and a tie rod due to the rust damage. They indicated to me that they inspected the car and found no other damage.
All research I have done so far has shown rust damage to the front right sub frame. I am not aware of any other rust problems found.

we find out the car may not be worth fixing ,about $1500-$1700.we would be in heaven if hyudai would fix the car like they should.
Bob Schilling Posted: 9/10/2008 8:14pm PDT
The only substancial rust the dealership could find was on the passanger side (right) front.
They replaced the front subframe (also called the engine cradle and "K" frame). I was assured that there was no damage to any component and that the rear subframe was in excellent shape, other than some surface rust.
I don't know if this will be the end of my story, but I've delt with my dealership and have a bit of confidence in them.
I was satisfied that they delt with it, without any hassle what so ever.
All was done with no charge to me.
Bob Schilling Posted: 9/11/2008 8:46pm PDT
Wouldn't you know it but I have a 2003 also, so needless to say I will be bringing it in for inspection
Brad Andrews Posted: 9/16/2008 11:59pm PDT
the same difficulties with a rusted broken sub frame.
I was driving and thought I ran over something in the road and had difficulties driving the car. I felt it was unsafe, when I brought it in to have it repaired, It was
scarier than realized. I am interested if any one has any information regarding any knowledge's from any recourse that is available ? Thanks for your responses.

By the way, considering what the dealer told me (it got rusted because I drove it in Illinois) and what Hyundai America told me on the phone (they are not aware of this problem, warranty has already expired, and I need to pay what dealer asks me to pay for the initial inspection), I was very skeptical about getting it fixed by Hyundai. I ended up with getting $1,000 as is for trade-in at local Honda dealer for a purchase of a new Honda. Most of you seem to have fairly good experience with Hyundai, but definitely not me.
call Hyundai Consumer affairs, they will ok you to take it to a dealer and they should fix it at no charge as long as there has been no outside influence, it took us one business day dropped the car off Monday will have it back Thursday or Friday no charge no hassle
I followed all of their instructions. When I last talked to the service guy he said that they were going to take care of it at no cost to me. Hopefully I will have my baby back by next weekend.
Kudos to Hyundai for taking care of their customers!

they really have been good no hassels at all, I still think they need to put out a recall though before somebody gets seriously hurt, alot of people dont find out of the problem untill its too late.

Before driving back to Mi, I had oil change. I was very fortunate that this shop put my car up on the hoist. Showed me a hole rusted out larger than my fist. Told me VERY UNSAFE. Lucky me for finding this out before my 1,500 mile trip back home that week.
Punched in "auto-body-repair" on garmin and found a shop and put a new frame on. Haven't checked with dealership yet, but maybe they will reimburse me? At least I'm alive !
When I purchased my car, I had it rustproof/underbody etc. Whats that worth?

My daughter was driving to school & the whole front end started to shake.We took car to the garage to get it checked & they said the whole sub frame was cracked. The garage I take it said I might want to check he thought there was a recall on the sub frame. I contacted the Hyandai garage
They put a new sub frame I also had allot of problems that resulted from this they put a whole in the exhaust system, it leaked fluids the tires need replaced & they where only a year old, the right side of the door is totally rusting out. I would never by another Hyandai. In the past 6 mon I had it the garage 6 times.
