Hi to all! I have a 2004 Sedona and about 3 months ago my check engine light came on. The dealership said all the Kias are having problems with the CCV and he diagnosed that to be my problem. They didn't have a replacement and they just reset my light and said to come back. Well...now the guy I talked to doesn't work there anymore and never wrote a ticket on what happened...so they won't replace the CCV b/c it's not in the memory. Will pretending this never happened hurt my car in any way? Or even give it less fuel efficiency or something??
THANKS!

The CCV's work intermittently, that's the problem. When it's not working, the fuel tank can't vent. This builds vacuum and the fuel tank pressure sensor detects that and the check engine light turns on.

When it's on and you loosen the gas cap, you will hear air rushing into the tank.

It won't hurt your engine; the whole system is just for emissions.

It will eventually fail, but you still have some time left on the warranty.
