What owners say about the structure

Verbatim from NHTSA complaints, newest first
“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.”

“The contact owns a 2004 Hyundai Sonata. The contact stated that while driving the vehicle, she noticed that her brakes were failing. The contact stated that she drove her vehicle to an independent mechanic who attempted to replace the brakes however, the mechanic informed her that her vehicle had a lot of corrosion on the brakes, and underneath the vehicle, which caused the brakes to fail. The contact stated that the mechanic did fabrication and installation of the brake line. The contact stated that she then took her vehicle to be inspected and was informed that the corrosion on the vehicle was too severe and the vehicle would not pass State Inspection. The vehicle was taken to the dealer and the contact was informed that the VIN was not included in NHTSA Campaign Number: 09V124000 (Suspension). The vehicle was not repaired.
