Sunroof exploded while I was driving. Had I not had the shade closed I could have been injured by shattered glass. Glass has been replaced at the dealer of purchase, via insurance claim with my agent. There was no indication that this would occur.

GM already has extended the warrant for faulty AC Condensers model years 2015-2017. This model 2018 experiences the same exact condenser leak as the 2015-2017 models. In fact special coverage adjustment 17336 which omits the 2018 model has the same failure. This warranty should be extended into 2018 as well.
