As I was driving up a hill in a residential neighborhood, the engine started making extremely loud noises and it would no longer respond to the accelerator. This was on a narrow two way street. I had it towed to the local Hyundai dealer who said it needs a used motor put in it for $4600 as it has "an internal engine problem" without going in to specifics. Engine had 97,000 miles and car was well-maintained.
