Great Truck

I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Currently in Litigation with GMC

This truck has been a nightmare! Its a beautiful truck but everything that could go wrong with the truck has. It has been in and out of the dealership 6 times now. First for the recall issues - excess glue problem on battery and seat belt positioner. Next, came the check engine lights at 7k miles which had to do with braking system. Then, at 30K more CELs which they attributed to needing system updates for emission systems. Truck also had oil pan leak, transmission cooler line leaks, and rear pinon seal leaks fixed at the same time. The CELs came back on shortly after repair. Finally, they found damage on 4 locations to the main engine wiring harness due to rubbing. They fixed that but damaged the steering column so it made a grinding noise on the wheel and was loose. Had them fix that which only worked temporarily. CELs came back on the vehicle. Truck finally died and left me stranded this past weekend due to a failing Diesel Pump and Transmission Cooling Regulator Valve. Finally, The rear window leaks from the factory but due to the amount of miles I have GMC refuses to fix it and wants 4.5K to fix the window and electronics it damaged. I have left multiple messages to my GMC case specialist only to be ignored but when I call GMC customer care they just transfer me back to them. Horrible customer service and an even worst truck.

Best truck we have owned!

Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!
