Sierra 1500 3.0L

There appear to be on Facebook and other GMC sites numerous complains about the rear window leaking from anywhere after a few hundred miles to thousands of miles. Mine started leaking just under 7 thousand miles.

It's been in and out of the shop with attempts to stop the leak.

Though work has been covered by warranty this is an annoying issue that I hope others will come here and report as well. The repairs are time consuming and if the dealer will not give you a loner vehicle becomes very costly in rentals as it takes a few days each repair attempt.
