NHTSA complaint #11324084, filed 2020-05, 200,000 miles“Smelling of gas and leaking on ground, as I'm reading this is a common problem which is very serious. I really think GM needs to include this 2003 Gmc Envoy as part of their recall as well. This has been going on for years it looks like and nothing has been recalled. Guess human life is not important.GM needs to recall this problem asap before someone gets hurt.”
NHTSA complaint #10572565, filed 2014-03, 76,000 miles“My car is reaping with the smell of gas on the inside and outside of the car. I called GM customer care center about this problem being hazardous and all they offered was a $150 voucher available at the Gmc dealership. I am confused as to why 2006/2007 models were recalled for this matter and the 2003 model was not recalled. I am afraid to drive this car because I believe it will explode!”
