I wanted to repost this 2-day old inquiry to find out if I'm being fed a line of crap by GM.
I'm the guy who'* been getting "Check Gas Cap" message since my first refill on my "new" used 30,000 miler.
Today I called the dealer where I bought the car. They said, "sure, bring her in. You have 30 days left on your warranty so everything should be covered." They said, though, that I could take it to a local dealer for service cause that would be 30 miles shorter distance (1-way). NOW BEAR WITH ME PLEASE.....................
I called the local dealer service tech. He told me to make an appt. and they should cover repairs, IF THERE WERE SOMETHING WRONG
. I said, "ok, suppose the gas cap was loose (which it was not). How do I know if I corrected the problem?" He said, "well, you can't right away". "You see, the system pressurizes and checks the tank for pressure leaks on a random basis, not with each start. He said it may take between 100 to 200 starts-and-runs before the system might recheck itself. I think, "Sure, right!
Let'* see.... 4 starts per day...........that'* about 25-50 days worth of starts before I find out if I really do have a pressure leak at the cap????" Gee, the warranty'* over then!!!!!!!!! This gives me only one option. Off to the dang dealer I go.
Questions: 1. Does anyone really know if this crap is true? If it is I would like 5 minutes, alone, with the engineer who designed this system. Surely somone on this site knows exactly how the system operates. How about it guys/gals??
2. Can I reset this slimey little message by disconnecting the battery for awhile?
3. If I can, will the system immediately re-check itself or does the programming demand that it go through that silly random sampling thing.
4. I spoke with Autozone personnel (usually VERY helpful). They said they might be able to read a code, but they were not permitted to clear it. COME ONNNNNNNNNNNNN.
