GMC, better get your act together or Honda/Toyota will own your truck market too!
Fan Clutch - Replaced under Warranty.
Rear Axle seals - @ 60K miles, Out of Warranty cost $400.
Rear Brake Light Driver Side - Corroded connection, have two notice letters, had first repair done under warranty, now that I did one post warranty (but withing mileage limit/age listed in letter), hope that GMC will refund the parts repairs That I had to Purchase from 2 dealerships to effect repair. Cost $140.
Air Conditioning Have had the control module replaced while in warranty. It has gone out again. It seems that the repairs are focused on the effect, not the cause. Another blog reported the cause of the problem-- a faulty vacuum module attached to the transmission that supplies vacuum to the A/C module is allowing trans fluid/mist to travel via the vacuum hose that supplies vacuum to the module, causing intermittent problems/ shorting out. In my case, so far, the dealer hasn't diagnosed the cause, the vacuum canister. I hope GMC takes responsibility for the faulty vacuum part and fixes the problem.
This vehicle eats batteries. Have had one replaced under warranty. Another one post warranty. NOTE TO OWNERS WITH ELECTRICAL ISSUES -- Have the battery load checked. I have experienced similar weird electrical issues as reported in other owners comments. Have the battery thoroughly load checked. In my case, the problems start when the battery is beginning to fail -- shorting of a cell prior to battery failure. Next time I will consider replacing battery with one rated larger than spec. With everything being electrical/computer controlled, batteries are being worked very hard.
Would you buy another car from this manufacturer? Don't Know
