Ourisman Chevrolet of Bowie

I purchased a 2011 Chevy Corvette and purchased an extended warranty along with it. I was told at the time that it was "bumper to bumper" coverage, just like a new car warranty. It was pretty expensive. Nine months later my air bag light comes on. I take it to my local Chevy dealership and am told it needed a new air back and harness for a price of $1350. I had them call my extended warranty company and was told this was not covered. I call Ourisman and talked to finance manager who said he would investigate and call me back. He never called back after leaving several messages. I did talk to two other finance people who told me that air bags are not covered under a new car warranty. I find this hard to believe. I never did receive a call back from anybody at Ourisman, therefore I am writing the negative review and am done dealing with Ourisman.
