Hello. I'm new here but the alleged recal will affect mostly Trailblazer and Envoy extended versions. You usually get the gas smell even if the gas cap is closed tightly. I've had my tank and stuff changed out about 2 months ago. The only way they will change it out is if you have a service engine light on and have a fuel/emission code stored. The way I got mine done was when the light came on, I called Onstar and told them about the gas smell. I had them run a test and they recorded the code in their records. I later called GMC to which they claim "no recall" in the works. When I stated my safety concerns with my 03 Envoy xl, they made an appointment with a dealership. The dealership noticed 2 leaking areas: 1 by the the filler neck and 1 by the fuel pump area. It took 1 week for the tank to get in but I'm happy and running! GM will never make a real "recall" because then they would have to pay for rental cars and such while the "un-safe" vehicles are in their shop.:rofl:
