I just left my car at the dealership and the odds are good that I'll need to replace the gas tank for the 3rd time. Unfortunately I didn't ask many questions when the tank was replaced previously as the repairs were covered under warranty and I figured the last tank would end the problem and it was just my bad luck. So, have any of you faced this same problem? My car has less than 40k miles and I see a trend developing here. Also, any advice as to how to proceed if they try to stick me with the bill on this obvious defect? Thanks in advance for any help.
