re: 04 Envoy - my service 4wd light came on in the middle of a 10" blizzard. I researched it and took it to Jiffy Lube and had the front & read differential fluids changed. Light went off and has stayed off. Now my "service engine" light keeps coming on - I'm concerned that I may have a crack in the gas tank as I have read many many other Envoy owners have experienced.
