Here is a new one. Especially on me. I was on a trip from Kentucky to New York. Car performing perfectly. Stopped in Ashland, Ohio for a fill-up. The Fuel door was locked and would not release even after following the owners manual instructions. Its not the first time I filled the tank so I should know by now how to do it. After a call to my hometown dealer with no help I asked if there was a local Chevy dealer. There was and off I went. The people were very helpful and after a few minutes the tech had removed 1 screw and unplugged the locking solenoid and opened the flap. Now it won't lock but is accessible. Anyone else have this problem? I will see if my local dealer will cover the replacement of the bad solenoid under my extended warranty.
