Underbody Shield problems of the 1999 Hyundai Sonata

The sub frame/k frame on my 99 Hyundai Sonata rusted out causing my driver side rear tire and passenger side rear tire to face outwards almost coming off and damaging my left control arm. I heard a loud pop and couldn't figure out what it was then realized the steering wheel was cocked at 180. I had to drive it home which was luckily only 2 minutes down the road, I had to drive 10mph smelling burning rubber.

I was pulling in a shopping center turning the steering wheel to the right, I heard a loud bang and got out of car, the drivers side wheel was caved in, had car towed to mechanic, he said the subframe was completely rusted and broke away from the car, and I was lucky that I wasn't going at a higher speed.

On 1/7/08 while driving '99 Hyundai Sonata GLS to work, pulled right proceeding down road. Possible leak from brake cylinders/ brake lines, nothing. Return trip, vehicle extremely erratic steering. Took to dealer of purchase (bb Hyundai, south brunswick, NJ). Delivered on 1/07/08 by driving vehicle. Vehicle extremely difficult to steer/ control, driving speed 25-30 mph. Vehicle delivered to bb w/96062 miles. Service mgr (lc) took information regarding problem - diagnostic cost of $95 +tax. Agreement made to determine failure. Informed by service mgr of problem - sub-frame rusted away - cost in excess $3400. Why not covered by warranty (10 yr or 100,000 miles) -"rust' was covered. Told auto not allowed on road. Question absence of warranty since sub-frame required part of front driven auto. Response given - buy a new car. Refused authorization to replace sub-frame. I contacted Hyundai USA corporate cs (j) problem conveyed /why no warranty coverage. Reply-"you must live by water,you are in NJ, why it rusted out". Told arrangements made for further investigation. Rec'd call (lc) contact from Hyundai, rep to review next day, with call from lc. On 1/11/08, no results from lc, to call back. Lc call at 1pm, Hyundai, as a good will gesture, to cover cost of sub-frame, not labor; costs unknown. Recall Hyundai(d) "I never heard of such a problem!', transfer to j -advised to 'jump on offer". Recall lc, cost unknown. Costs required by dir/parts/ Hyundai. Recall Hyundai (t)"Hyundai is aware of problem - rusting sub-frames, working on same". Request supervisor, company policy directive, parts director with authority. Contact bbb, 1/12/08, call lc, no cost value from maintanence supervisor cost. Lc call@ 4 pm - cost $850, need okay to continue. Recall lc 5 pm - ok. Informed new sub-frame would not arrive until 1/16-1/17/18. Requested old sub-frame upon payment of labor - unable to comply was the answer.

: the contact stated while driving 60 mph on normal road conditions, the right wheel passed over a small dip in the road, and the vehicle began pulling to the right. The vehicle was lifted up, and it was noticed that the frame where the control arm was attached had rusted. The dealership was contacted, who suggested to bring the vehicle to a dealer for repairs. The manufacturer was also contacted, who informed the frame was not covered by the warranty. The vehicle remained inoperable after the incident. The contact expressed concern because the frame should be included in the vehicle's 100000 mile warranty.
