2008 GMC Sierra 1500 Reviews

its a great truck but only one problem! the wires for the headlights on the sierra always get shorts in them and everytime u get going down the road one is out!!!

I had the truck less than a yr and the transmission went out. A yr later the vent valve assembly and solenoid had to be replaced and moved and it was under warranty and still cost me over $300 to get it fixed. Now 2 yrs later the check engine light comes on and guess what its the vent valve assembly and solenoid again. Wow Chevy/GMC really use to mean quality but really not thinking so now. Previous 4 trucks were all Dodges and never had any issues!!! Looks like I'll be going back to the RAM soon!!!!

Transmission had to be rebuilt at 10K and again at 20K miles. No known "fix" for the problem. This truck is pampered and gets only 7K miles a year of driving. Professional Grade... Not hardly.

love this truck no problems!!!
