Poor transmission on 2018 sierra

Very poor transmission going up hills it doesn’t no if it wants to shift up or down truck shakes it’s embarrassing when people in it they ask what’s wrong with it I tell them good question ask GM the service centre where I bought it just smile when you tell them about it


GMC makes garbage!

My GMC SIERRA 1500 w/ 5.3l V8 has been at the dealer for 5 months waiting on an engine due to lifter failure. Worst customer service ever. Don't by from GMC.



Issue after issue. This truck is serviced religiously by GMC dealership we purchased from. AC went out in February, CV joints had to be replaced in July, computer system went out in August, transmission went out in October.


new owner of the gmc denali, 2018 6.2

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me


best in class

My 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 truck

The 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


Transmission failure is very common

Transmission 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.


Most reliable car I have ever owned

This car has met all of my traveling needs. It is a great looking car and im sure i will get a lot of work out of it as well. My family will love taking trips in the car.
