What Owners are Saying About the 2018 GMC Sierra 1500 Double Cab

"Awesome Teuck"

"I absolutely love my truck. Comfort is better than our Cadillac and it looks awsome. Luxury interior and amazing in the snow."

"Transmission"

"Terrible vehicle. They sold them know transmission was bad. I’ve put new transmission in 2021. And now it’s going out. Will be third transmission jn 142,000 miles"

"couple of hiccups and the infamous tick-tick-tick"

"Trailer brake control likes to come on when not towing for no reason. I put 1 or 2 gain on it and it seem to correct the false signal. Vent actuators get stuck I believe it may have corrected once by accident when the battery was disconnected. Had to replace torque converter. Assuming previous owner abuse. Bought the truck at 87000 mi. and it has tick tick tick since day one. Today at 192000 still tick tick ticking. It’s been a good truck."
