Everything I wanted in a new truck!

Love it! It's beautiful, it drives great, it's comfortable. Great dealership to work with. No glitches, no surprises during the buying process. Would buy from this dealership again no questions asked.

Would not buy again!

Im 58 and have owned nothing but chevy or gmc 1/2 tons since i was 30. Leather drivers seat is incredibly uncomfortable, gas mileage is 2+ worse than my '18 w same set up, WHY?? My right foot grabs the gas pedal often when applying the brakes. I swear the truck surges forward when i take the foot off the gas pedal and apply the brake. The tranny is a lot better than the 8 speed in the '18. Would say i am very unhappy with my $60,000 purchase and will not be guying another GM truck

Great truck

This truck is great! The only problem I have is that there is a rattle noise in what sounds like the steering column. Overall, this is a great truck with plenty of room to move around.

Great Truck

The new 2021 Seirra Crew Cab is a great truck. Super comfortable, and great ride. Has plenty of power with the 5.3 V8. This is my 3rd Sierra in a row, and the best one yet.

Expect engine issues without any resolution

Engine issues at 4000 miles? No thanks! When you spend the kind of money for these vehicles these days, you should be able to know that they would be dependable! Garbage!

Sierra Denali, and easy choice

After driving both Ford F150 and Dodge, the Denali was an easy choice. I have one on order. Overall the truck drove, handled, and stopped better. The others had a bit softer interior, but controls are more intuitive with the GM. Lastly, could not get a truck the way I wanted with either Ford or Dodge. Either packaged options and they would not, or could not order. Local GMC dealer ordering exactly the way I want - selling at invoice, delivery in 4-5 weeks.
