NHTSA Complaint #11619495 — 2009 HYUNDAI ELANTRA

I previously brought my car in for a recall in 2014 for underbody corrosion and it was repaired; however, now there has been severe corrosion of the underbody, not just the components listed in the recall but nearly the whole underbody is severly rusted and corroded (see pictures below). My mother was driving my car in July 2024 when the rear subframe completely snapped near the control arm while she was driving. Luckily she did not get injured or hurt, but it could have been potentially fatal especially with this happening. I reported this to Hyundai Motor America and towed my car to the dealership. The dealership has submitted a goodwill request to cover the repairs of the recall not the other ones; however, I raised a potential oversight for the previous recall whereby the corrosion of other components not explicitly named in the campaign such as the sway bars and backing plates which could also directly impact the vehicle’s structural integrity and safety if corroded. The omission of ALL of the components that would be subject to corrosion in the recall campaign could have been an oversight and the recall should have covered all critical underbody components prone to corrosion, not just the ones explicitly listed in the recall. Other parts corrosion are a direct consequence of the same environmental factors that led to the corrosion of the subframe and control arms. Since these components are interconnected, and since Hyundai has acknowledged the issue with the crossmember corrosion through the recall, it stands to reason that the other components’ damage should also be addressed as part of the overall remedy. These additional parts would have been exposed to the same environmental factors (e.g., road salt, moisture) that caused the other components to corrode. Since Hyundai acknowledges that these environmental factors led to corrosion in the subframe and control arms, it stands that the other components would also be affected too.
