Three problems related to power train have been reported for the 2013 GMC Sierra. The most recently reported issues are listed below.
The contact owns a 2013 GMC Sierra 1500. While driving 40 mph, the contact stated that the vehicle would jerk and shift in between gears. The vehicle was taken to the dealer but was not repaired nor was the failure diagnosed. The manufacturer was notified of the failure. The approximate failure mileage was 200.
At this occurrence the hood latch does not keep the hood tight when closed. The hood rattles at speeds over 35mph and appears as though it is going to open. As a result of attempting to sufficiently securing the hood, I subsequently dented the hood. I have had the body department at the local dealership look at it and they found that the hood latch needed to be adjusted. After another 2500 miles, this rattle has returned. The complaint is that this is the second 2013 Sierra denali that I have owned since October 2012, since the dealership bought back the first one after numerous problems including the transmission being replaced at 6250 miles and numerous efforts to fix the hood. Same problem two trucks is a cause for concern!.
The transmission on this vehicle slips sometimes between 2nd and 3rd gear and also when parked on a hill and put into drive the transmission shifts late into 1st gear.
