2011 Denali HD Duramax 6.6 Turbo DEF Tank Issues!
2011 Denali HD DRW 4x4 with the 6.6 turbo Duramax. The DEF Tank is full, yet the DIC
says that I need to refill the tank and that I am limited to 55mph. After
a while it will go down to 5mph. I went to the GMC Dealership and they
have not heard of "any issues with the DEF Tank" Ive tried letting the
truck run for 1 hour...and that still did not fix the issue. I also drove
it 30 miles down the freeway. The truck has 4,000 miles on it. Needless
to say, I am NOT a happy owner and maybe I should get a King Ranch or Dodge
DRW. I am not the only duramax owner having the issue. Brand new truck
and I dont know even know how many miles I have left until it puts me at a
crawl. Thanks GM! Quality Product indeed
