Sierra 2500 Denali 6.6L Diesel

  • Automatic transmission
  • 65,000 miles

I always read about how the Dodge was junk and all of them have dashes that cracked... Well, welcome to the new quality of the GMC Duramax Denali. My dash has cracked in 2 places above the steering wheel and 1 more crack by the air bag. I just took epoxy and glued the cracks, looks like crap, but these dashes are cheep and why replace it so it can crack again?

problem #2

Sierra 2500 LS 6.6L Diesel

  • Automatic transmission
  • 130,000 miles

I paid 50,000 dollars for this truck and for no reason the dash has cracked in two places. It is sad that GMC will not recall this because a lot of them are doing the same thing. I am in business and if I put this kind of sh*t out there, I would fix it and if not I would be made to fix it. They know the problem and the truck is not cheap.
