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.

I took my car to the mechanic for a “once over” before driving from New Jersey to North Carolina. This car has only 41,000 original miles on it as we bought it new in 2005. Upon inspection, the mechanic came back with certain repairs that are needed due to age; but he was extremely concerned about a severe safety issue that the subframe had rotted out and needed to be replaced. This is a known corrosion issue with other years of manufacture for this model. There was a class action suit for this specific issue for 1999 to 2004 Sonatas. The subframe threatens to collapse from rust at any time and is an extreme hazard to the driver, passengers, and others on the road. There was absolutely no warning of this issue prior to this inspection, making it even more dangerous as it affects many drivers who are unaware of the issue.

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)

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.

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.

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.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.

This bulletin contains information about the proper removal of the windshield wiper blade protective cover on all models. If the protective cover is not removed correctly, there is a possibility of the rubber insert and rail spring becoming partially separated on the inner side of the wiper blade, which could lead to poor wiping performance and/or possible scratching of the windshield glass. Follow the procedure in this bulletin to properly remove the windshield wiper blade protective cover on all new wiper blades.

This bulletin provides important checkpoint guidelines when performing engine oil and filter change services.

Hyundai applies a Paint Protection Film (PPF) on new vehicles before delivery to dealerships. It provides a barrier between the paint and contaminants, such as rail dust, acid rain, and industrial fallout. In rare cases, the paint can become clouded under the PPF. These spots are the result of moisture trapped between the PPF and the paint.
