2001 hyundai accent

I have a 2001 hyundai accent with the engine light one did the gas cap
thing, didnt work. driving one day took it to a local mechanic to see
if he knew, He diagnosed it as a bad manifold, said it was warrantyed
to take it to the dealer turned off the light.


took it to the dealer for a look at this issue. Dealer said he couldnt
diagnose it since the light was off.

My question is this, Is there some type of histroy you can get this
information off the car???

Beczuse its on again and my intentions are to take it back to dealer,
however I get a little tired of them trying to blow me off. so any
information is good informatiion


thanks
