Service Department sucks… 4 hours wasted and don’t trust diagnosis that took 4 hours and no one had even touched underside of vehicle…I checked…furthermore service has been lackluster nearly every time I’ve diagnosis that took 4 hours and no one had even touched underside of vehicle…I checked…furthermore service has been lackluster nearly every time I’ve opted for using the service dept. GMC warranty sucks …known problem with transmission serviced 1st with fluid change several years ago, then torque converter changed some time thereafter and was out of warranty because they probably should have changed torque converter instead of just the fluid the first time. Same problem is 3rd time now. Now torque converter and valve body they tell me needs replacement…and once again out of warranty with 68000 miles on vehicle total. Just was diagnosed from computer apparently because underside of vehicle was never touched…I looked… So GM warranty replacement torque converter only for one year?…I guess the new torque converter on new vehicle only warranty is one year too?… When replaced last time I had to wait three weeks for a gm part even after I offered to pay and deliver an upgraded/ superior aftermarket unit. Last issue on last oil change visit was check engine light I wanted addressed. Code showed due to MAF sensor code and was told to change air filter…air filter was relatively new but replaced anyway resulting in same code. Service department never even offered to change sensor…I Changed MAF sensor myself-problem solved. Service department nearly worthless except when stealing change and contents of vehicle it seems. I will never deal with this dealership or service department again…told my salesman that I’d love to buy another vehicle from him but unless he finds new brand and dealership there is no chance. xxxx on GMC, this establishment and service department. It won’t be a GMC to replace this truck…ever… You should add xxxx poor rating to your choices below for this dealership… More
