I have the 5.3 4x4 with 3:42:1 rear axle, the truck seems rather sluggish to me. What I hate is how it is always trying to shift up to a higher gear which makes it slow. Not a day goes by that I wish I had purchased the 6.2 but in order to get that engine you have to upgrade from SLE to SLT, lost more money. I think it's stupid that GMC won't let you select whatever engine you want it the truck.

All in all its a great truck. The flaws that I seen so far are these, but not enough to sway you from not buying. Love the heated seats and auto start. 1.) Head lights Suck. 2.) Head rest feels like a brick. Probably so you don't fall asleep. lol. 3.) Needs more storage space like on top of the dash or center console style changed. The 3 sections behind the cup holders on the split seat styles are completely useless and waste of space. The dividers need to be either removable or gotten rid of. Would be a nice place for pens. Also the bottom center could pull out with a nice configuration there. Instead you have to lift the bench to get it opened. 4.) Ride is a little stiff, but that could be because its still new.

Transmission issues and electrical issues

The transmission went out at 134K, GM sucks. I’ve had weird electrical issues like the sound completely shutting off every other time I start it when its winter time. Sometimes a security light will pop up and then go away. Randomly the front brake caliper locked up on me for a couple days then stopped. A/C condenser went out at 115K and caused me to replace the radiator too. Pinion seal on the rear U joint / differential started leaking around 100K. Will never buy GM vehicles again.

Bought mine new. It's never let me down. Just replaced the original battery after getting almost 7 years of use. No mechanical, electrical or any other issues at all.
