We bought the car when it had about 60,000 miles on it. My wife drove it basically around town. At about 90,000 miles I thought it needed the wheels aligned but our mechanic said the cradle bolt (sub frame) was rotting out and it was unsafe to drive. The part from the dealers cost $1500. We checked availability from junk yards and the common response was laughter. Since we were not the original owners, Hyundai did not offer any recourse. We sold it to a mechanic who said he would take a chance on it.
this issue was covered under a recall. the mechanic liikely had a Hyundai dealer fix itt for free. Hyundai or the dealer or tthe mechanic owes you $1500 bucks, in my opinion.
