Either I got a lemon, which is definitely a possibility, or there are significant issues w/ GMC as a manufacturer which is evident. The american car industry just won't do business differently but then again, they don't have to- they get bailed out by the government repeatedly. I leased this vehicle in October, 2012. The issues cited above, were related to 3 bad fuel ignition valves, they were replaced finally after I took the car back to 2 different dealers and nearly 6 months of complaining. The issue was when accelerating, the rpms would stick at around 5-6 when I was traveling around speeds of 45 mph to 60 mph. The transmission wouldn't shift into the next gear. This was highway driving, but will happen on 4 lane roads as well. During the same time frame, the stability of the car in ice/snow only worked if the tow package feature was turned on. Otherwise, I spun out leaving our neighborhood going down a slope at speeds of less than 30 mph. Dealer said it didn't make sense and did nothing. I just keep the tow feature on during snow/ice/rain. Electrical issues, heating/cooling system wasn't working correctly, it wasn't heating unless the temp was put at 80 degrees. Only thing dealer would concede was there was a kink in the hose. It's happening again- we have to set the A/C at 60 in order for it to cool the car down. Very disappointed in this car. Once again, the issue with the rpms and heating/cooling system is happening again. I'm paying off this lease early and hopefully will not get a penalty. This is a poorly made car.
