This Year's Model Updates:

For 2015, the GMC Sierra 1500 sees a number of changes. Newly available is the latest OnStar system (with 4G LTE WiFi capability) and new power-folding trailer-towing mirrors. The Denali trim level gets the magnetic ride control suspension as well as a spray-in bedliner. Later in the model year a new powertrain option, consisting of a 6.2-liter V8 paired to an eight-speed automatic transmission, debuts.

Pros:
  • Quiet highway ride.
  • Well-built, comfortable interior
  • Powerful and fuel-efficient engines
  • Many available configurations
Cons:
  • Six-speed's transmission ratios too widely spaced for optimal towing performance
  • Touchscreen interface slow to respond at times.

    as i read the reviews on this truck as I've been buying gmc sierras religiously for 30 years, i pretty much ignored most of the reviews on the 14s...but since I've had this 2015 i have put on 9000 kms and already i,m in for differential work..appparantley i,m not alone on the gm forums the main complaint on the differentials is a strange humming noise and we will wait and see where this goes..i,m sitting waiting for the news on this as i type,,,lets hope its a problem that can be solved as i really like this new truck..smooth, classy, looks great and total comfort...

    This is my third Denali pick up. Huge buyers remorse buying black but that's my fault. It does look amazing few hrs after its washed. Was really wanting the 6.0 and eight speed tranny but they're so hard to come by I had to settle for the 5.3 and the six speed. My 07 had alot more power it seems. Plus it was all wheel drive. But I am getting around 16 miles per gallon instead of 13.5 with my old Denali. Still working through the countless menus on the electronics. I'm over my trial for the Wi-Fi and was not impressed.The drivetrain has a vibration at around 41 miles an hour that I need to take back to the dealer and have checked out. It was an insane amount of money but I'm not unhappy.
