best in classMy GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

Better than my old truckThe truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck
No GMC Service on March 26, 2021
Transmission failure is very commonTransmission failure is very common. After 30+ emails and calls to Gmc they have responded with the same amount of emails and phone calls however there’s no resolution to my problem I keep getting pushed to someone that cannot make a decision in regards to the transmission failure that I am experiencing. I am reporting this transmission problem to the national transportation highway safety administration in Washington DC if you were having the same issue you should do the same

This is an attractive and enjoyable vehicle.I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.
