Underbody Shield problems of the 2001 Hyundai Sonata

I bought this used 2001 sonota from a local guy who rebuilds cars for resale. I understood that it came with a salvaged title. However, I was assured that the vehicle was safe to operate. Six weeks, 4,000 mi. Later I hit a pot whole on my street and damaged the steering. I took it to a local repair shop and discovered the r-side sub-frame was broken due to corrosion. Who is responsible for allowing a vehicle that has a possible r-side sub-frame recalled, to never get fixed and placed back on the road? fortunately, it broke at a low speed in front of my house.

The contact owns a 2001 Hyundai Sonata. While changing the oil in the vehicle, the contact noticed that the sub frame near the engine was corroded. He touched the sub frame and his hand went straight through. The vehicle was taken to a dealer and they stated that he lived in a rust belt and discovered that the control arm was held in place by only one bolt. The vehicle was repaired by taking a sub frame from a salvaged vehicle. The current mileage was 83,959 and failure mileage was 83,949. Updated 12/12/2007 updated 12/12/07.
