2004 Hyundai Sonata GLS front sub frame (K Frame) has rusted out but I guess for certain VIN numbers there was a recall. Mine has the same issue and has caused suspension issues with the control arms and axles, subframe has snapped due to rusting in Michigan.

I got this car a Hyundai sonata 2004 about 2 to 3 years ago. At first I didn't notice the problem until a couple months into me having the car I was on the freeway and it suddenly felt like I was out of control of my car and the back end was like swerving like I was pulling a trailer. And ever since then it's gotten worse now my front right tire goes flat randomly. A friend mechanic of mine looked at it and said that it is a suspension He just doesn't know what part of the suspension. This is dangerous because I could lose control of my car I have at any time. That could be detrimental and there is a recall in it seems like almost every other state but Utah. For the exact issue that I'm having and I don't think that's right. I've had issues with this car ever since I got it. If you guys could look into this that would be great Also this form asks the approximate date that something happened it happens all of the time. To the point where I'm afraid to drive it at all. I also it's gotten so bad that sometimes when I'm going only 35 mph and I hit like a pothole it will severely swerve and I will lose control of my car or if I turn my car I turn my car my steering wheel the right way and I lost control of my car it started swerving and I was on a mountain..

My 2004 sonata which was manufactured 05/07/04. has front frame corrosion exactly like the 089 safety recall that hyundia issued already for 1998-2003. My car was manufactured a few months later and they are denying the repair because it doesn’t fall in their production dates.

The front subframe has a hole in it it rusted for some reason and upon research there was a recall on this particular issue but now there isn’t one. I went to two dealerships and they informed me that Hyundai had recalls on this issue that’s why I’m confused on why when I search by my VIN there isn’t any open recalls. Just because they isn’t any open recalls on this doesn’t mean that people aren’t still experiencing this issue.

THERE IS A RECALL ON 2004 HYUNDAI SONATA FOR BAD SUBFRAMES THAT HAS BEEN AN ONGOING ISSUE SINCE AT LEAST 2001. THE SUBFRAMES RUST AND ROT OUT! MY 2004 SONATA HAS ONLY 84K ORIGINAL MILES AND I RECENTLY TOOK THE CAR TO A MECHANIC TO REPLACE A CONTROL ARM AND I WAS TOLD THAT THE REPAIR COULD NOT BE PERFORMED DUE TO A ROTTED SUBFRAME! I CALLED HYUNDAI MOTORS OF AMERICA AND SPOKE WITH CONSUMER AFFAIRS. I WAS TOLD THAT ACCORDING TO THE VIN NUMBER ON MY CAR THAT THE RECALL WAS NOT ON MY CAR! THERE IS A KNOWN ISSUE AND RECALL FOR THE VERY SAME ISSUE THAT I AM HAVING. HOW CAN THEY TELL ME THAT THE RECALL IS NOT APPLICABLE ? THERE PROBABLY HAS BEEN THOUSANDS OF 2001-2004 SONATA'S THAT HAVE HAD THE SUBFRAM REPLACED UNDER THIS RECALL .. I DONT UNDERSTAND WHY HYUNDAI WOULD NOT ACKNOWLEDGE THE ISSUE AND COVER IT UNDER THE RECALL .. THIS CAR HAS 84660 MILES AND THE CAR IS OTHERWISE MINT ! NOT A SPECK OF RUST ON THE ORIGINAL BODY!

WE OWN A 2004 HYUNDAI SONATA (109,000 MILES) WE HAD A FRONT END COLLISION WITH SIGNIFICANT DAMAGE. ME AND MY WIFE SUFFERED MINOR INJURIES AND THE AIRBAGS DID NOT DEPLOY. WE FOUND OUT ON THE INTERNET THAT THERE ARE FREQUENT COMPLAINTS IF THIS FAILURE AROUND THE NATION AND ALSO IN MANY HYUNDAI MODELS ACROSS MULTIPLE YEARS. WE ARE FILING THE COMPLAINT SINCE THE ERROR IS CRITICAL AND SEEMS TO BE SYSTEMIC IN HYUNDAI VEHICLES. WE DO NOT KNOW IF NHTSA HANDLES CARS THAT ARE OVER 100,000 MILES BUT WE FELT A COMPLAINT WAS WARRANTED SINCE THE CONSEQUENCE OF THE ERROR IS SO EXTREME. WE FEAR FOR OUR SAFETY WITH THIS VEHICLE NOW! BEING A DISABLED VETERAN, ON A FIXED INCOME, WE FIND IT DIFFICULT TO ACCEPT THAT HYUNDAI TAKES NO RESPONSIBILITY FOR THIS PROBLEM. ITS NOT EASY FOR US TO REPLACE THE CAR.

THIS IS A COMPLAINT, THERE WAS NOT AN ACCIDENT. THERE IS A CLUNKING NOISE FROM THE REAR SUSPENSION AREA. I HAVE HAD THE REAR STRUTS REPLACED AND ONE BUSHING ON THE RIGHT SIDE. I HAVE HAD THE VEHICLE CHECKED BY THE DEALER AND FOUR INDEPENDENT SHOPS. THE DEALER SAYS THEY CANNOT FIND ANYTHING WRONG. THE INDEPENDENT SHOPS HEAR THE NOISE BUT CAN'T LOCATE WHERE IT IS COMING FROM. ON THE INTERNET THERE ARE MANY REFERENCES REFERRING TO THE ISSUE. I AM RELUCTANT TO TRAVEL A DISTANCE NOT KNOWING THE CAUSE OF THE NOISE. I HAVE WRITTEN TO HYUNDAI. THEY SAY THEY DO NOT HAVE ANY RECORD OF COMPLAINTS RELATING TO THIS ISSUE. I AM IN THE MARKET FOR A NEW CAR BUT WOULD NOT SELL OR TRADE IN NOT KNOWING THE CAUSE OF THIS PROBLEM.
