Sierra 1500

  • 600 miles
Discovered undercarriage frame major rusting, entire undercoating peeled and cracked away in over 70% of iron/steel structure, major rust is visual on all bolts connected to suspension and frame. GMC chat ran my V.I.N. and indicated it was manufactured in Mexico. GMC corporate chat claims that my issue needs to be taken up with the dealership and to check into the state's of nh lemon law. Nh dealership claims a recent bulletin allows them to buff the frame down and reapply undercoating which their dealership is now equipped with. Dealership claims the warranty thereafter would be 3 years/36,000 miles. All warranty information in GMC warranty booklet only indicates body sheet metal at 3 years/36,000 miles for rusting, pitting and peeling of undercoat.
