Owner reports
Selected complaints filed with NHTSA by 2005 Hyundai Sonata owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2005 Hyundai Sonata. The contact stated that while her daughter was driving at 45 MPH, the vehicle rode over a pothole which caused a fracture in the subframe. The contact had taken the vehicle to several independent mechanics and was informed that the failure was caused by severe salt corrosion. The dealer and the manufacturer were notified of the failure and informed her that there were no recalls associated with the VIN. The vehicle was not repaired. The failure mileage was approximately 134,000. Consumer stated part# FC112 is used for 2003, 2004 AND 2005. 2003 AND 2004 of the same make and model are already recalled for the same issue with the subframe having rust due to excessive salt exposure, but SOMEHOW the 2005 which is EXACTLY the same part and problem has not been recalled.
The contact owns a 2005 Hyundai Sonata. The contact stated while having a state inspection performed, the inspector informed the contact that the sub-frame was completely rusted.

Upon inspecting the undercarriage of my vehicle found the right side of Front Subframe Cradle Suspension rotted almost completely through. When researching for issues pertaining to this model found a TSA was issued , after a lawsuit in California, for the years prior and after my vehicle. The damage is concurrent with the TSA bulletin but excluded. How does a manufacturer whom obviously is aware of an ongoing issue allow so many people, families and children, drive and risk their lives on our public roadways. Is their a subclass recall that will aid those like myself take corrective action.
Severely rusted out and corroded front subframe, only noticed it on accident very recently, and my car is the last year of a generation that was recalled for this very issue within the Salt Belt- I live right at the bottom outskirts of the Salt Belt in NKY, and my car is the only year not recalled for subframe corrosion. It's bad and I'm freaked out and can't afford it unless I figure out how to do it myself without prematurely dying due to a dropped engine or something similar (premature because if I don't get it fixed soon I reckon that fate isn't too far off)
My car's engine cradle, cross member or subframe is rusted out and the OEM replacement for my VIN number won't fit it correctly I'm getting really upset because this could be dangerous for me and my two young kids. I've already paid the mechanic $600 for the replacement part when it really only costs $450 at the most and the two he has ordered before have both been either too big and it says that it is the correct replacement part. What is going on?!!! If something isn't fixed soon and something happens to me or my kids there is going to be a lawsuit.
My mechanic just took a picture of the subframe of the car which is almost completely rusted through. He said that this is extremely dangerous and that if it was to break while driving the car, I would loose control. I have seen numerous complaints about this on the 2005 Hyundai Sonata on the internet which makes me think this is a common issue.
I had taken my 2005 Hundai Sonata to my local mechanic for a tire alignment, and it is then when I was told that the front subframe was rusted from the inside. There was no indicator of this beforehand, and had it been let be, I could have lost control of the car while driving and been in an accident.
I own a 2005 Hyundai Sonata gls. While driving down the freeway at 70 MPH the car suddenly became hard to control, as in it started pulling extremely hard to the right. I had to drive home with the steering wheel cocked to the left in order to go straight. I brought it into the shop thinking it needed an alignment - both front tires were tilted in at the top - what I found out was that the subframe was rusted in half. It seems very shady to me that there is a recall for this exact problem for pretty much every year except 2005. This is the same model as the 2004 and it was manufactured that year as well. *also, the trim on the car, which is what makes it more expensive, is constantly coming off while I'm driving. The silver trim around the passenger window flew off on the tollway. …
The engine cradle and both rear upper strut mounts are corroded to the point that the car is unsafe to drive and presents a safety hazard to its driver, occupants, and others on the road. It will not pass the annual pennsylvania safety inspection. The mechanic showed me (the owner) at least one large hole in the cradle (silver-dollar sized) as well as long three-finger wide holes in the upper rear strut mounts. (this is similar to a problem that I encountered in 2010 in my Hyundai elantra (rear suspension only in that car), reported to the nthsb and subsequently rectified by Hyundai USA.) moreover, this is similar to problems cited in robert d'elia v. Hyundai motor company and Hyundai motor America and rectified in a subsequent settlement and recall. This concerns a car with 100xxx miles on the odometer. Car was undercoated by dealership at pos. Driven exclusively in a salt-belt state. …
Failed inspection in part due to front subframe rust through. Called Hyundai and spoke to a claims rep. By the name of mike ext.631677. Mike told me there were recalls on sonatas up to 2004 for this problem, but not 2005. The 2005 model is the same model as 2004. The model year didn't change till 2006 so why was 2005 excluded from the recall? My car has 115K miles on it and the underbody is always washed during winter seasons. Mike told me it wasn't under warranty, and that Hyundai would not be able to do anything for me, to contact my dealership, maybe they would do something. I have a 1969 camaro and the subframe is fine. How is it the a car 10 years old has a bad frame? Hope you will be able to help us.
