Sonata

  • 175,000 miles
When having my car aligned, a technician showed me that the right front subframe is rusted through. Supposedly Hyundai fixed this 5 years ago, with one of two fixes: Either replacement or drilling drainage holes and apply a rust protector. One can see a hole drilled on the left subframe but not the right side. Besides my car, one has to ask: Did Hyundai really do anything to fix this situation or did they act like they did? a car rusting through the frame in five years is unheard of, and I fear others might have this same problem. Hyundai does not want to talk to me.

Sonata 6-cyl

  • 42,000 miles
I took my 2004 Sonata for inspection and was told that it would not pass due to a large hole from corrosion in front passenger subframe near control arm bolt costing $1200 to fix. After finding out that this was recalled and I was never notified, I contacted Hyundai and was told that my car was covered (I am in so-called "salt belt"). when I called the dealer back, I was told that my VIN is not included in the recall. The dealer then called Hyundai and dealer called me back stating that Hyundai would not cover. This hole can get larger and potentially cause the wheel to fall off while driving. My approx mileage is only 42K. Why is it not covered"!?!?!" I'm getting the run around.
