After we announced that the Stage 1 kit for the Cobalt SS was out and the mad dash began, we started getting comments, emails and phone calls from people upset about how the Stage 1 kit voids their factory warranty. GM HPVO would never put you out like that and we here at GMTS would never lead you to water only to shoot you when you started to drink. Rest assured the Stage 1 kit for the LNF is in full compliance with your factory warranty and we’ve worked with GM HPVO to make sure your dealers know what’s up as well. A special bulletin has been issued that you can reference to your dealer to help satisfy any warranty concerns which you can find after the break.
