i bought this new and i was pulling a camper and the drive shaft fell out at 3000 miles. i have 32000 miles now and it shakes and i have bad chattering in the rear. I was told it is the drive shaft again.but it was not.i was told it was part of the operating of the truck and this came from gm.they also said i will need to live with it. be careful if you buy a gm truck.
I am overall very pleased, had to find a dealer in Southern NH as the dealer I purchased from was less than... I also had tire sensor issues but was taken care of under warranty/recall...Have had several recalls that all went well. Initially I had hard downshifting issues into 2nd...dealer resolved that thought a recall, not that the recall was for that but after the recall was done the shifting issue was no longer there. I have 24K on mine, I use it to plow my farm and am pleased overall. My last Chevy 1500 lasted 18 years I expect this should do as well.
The truck has been in the shop 5 times already each time taking over five hours even for something as simple as an oil change. Cruise control on button works only half the time. Climate control makes noise. Shifts hard. But can tow 17k and still get 10mpg. impressed me. Exhaust brake works good but doesn't work at lower speeds.
