problem #2

Sonata 4-cyl

  • 43,274 miles
Fracture of both front coil springs in suspension. Resulting in dangerous situation in which coils could have ruptured tires resulting in dangerous situation. I recognized issue early and had both front coils replaced and sway bar links replaced as well. I see that earlier Sonata models from my same year have been recalled for this concern. I brought this to attention to local Hyundai dealer - they stated my VIN showed no recall. Obviously, recall should be expanded to include my model (made in Nov 2010 in Alabama).
