the diesel exaust fluid system is junk. 3 seperate problems
Just got my truck back from the local Chevy dealer in Marshalltown Iowa who replaced the DEF tank. They had it for a week. This is the 3rd trip the truck has taken to a GM dealers shop to fix a problem with the Diesel Exhaust Fluid sensors. I have no confidence that the problem is fixed and that it won't be a continuous problem. The dealer replaced the whole tank because they said that the sensors could not be replace individually; however, two years ago a dealer in Wichita Kansas fixed the DEF system by what they described by replacing two bad sensors. That was the 2nd time in the shop for the DEF system. The 1st time was at a Chevrolet dealer in Hugoton Kansas who simply reset the computer then charged me over $300 claiming that it was not a warranty covered repair. After I contacted GM customer service I got a refund from this less then reputable dealer.
When I purchased this truck in Kennesaw Georgia almost 4 years ago it cost me over $56,000. I wonder what rights I have in the state of Georgia under their lemon law or if General Motors has some sort of a solution to make things right for all the inconvenience this has caused me....
