Sierra 1500 SLT 6.2L

  • Automatic transmission
  • 16,156 miles

The car rumble when passing from V4 to V8. Again the dealer have no solution... I never hate a car as much as this dump, transmission knocking problem, rumble problem, what next?

Don't buy GM, if you have any problem, the dealer solution gonna be "It's normal". It's a real joke this company!

Sierra 1500 Denali 6.2L V8

  • Automatic transmission
  • 5,500 miles

Truck has been in shop 4 times to fix. No fix available. Service department says GMC HAS GUIDELINES THAT MUST BE FOLLOWED BUT NO SUCCESSFUL FIX IS AVAILABLE. Now I am being told the next step is for me to purchase new tires and that the tire on the vehicle are not recommended by GMC, yet they were on the vehicle when I purchased it brand new.
