  By texasbuyer777 - September 16 - 7:39 am

  update to previous report, exhaust fluid tube was not connected from the factory, dealer repaired, software was doing its function reporting a malfunction, 1000 miles today, towed a 20 gooseneck weighing approx 10,000 lbs., towed like a feather, entire truck engineering is 100% better than my 2009 chevy 3500. very quiet interior, avg 12mpg towing, 17-18mpg empty.

  Worst truck I have owned so far. - 2011 GMC Sierra 3500HD
  By zolo1978 - April 20 - 11:11 am

  At 23,000 miles the exhaust fluid warning came on, took it to the dealer and they took 2 days to fixed it. At 43,000 miles something outside the engine malfunction It cost me $18000.00 obviously they told me that that is not cover by the 100,000 mile power train, now at 53,000 miles something with the transmission went bad and the dealership is telling me that it will cost around $800.00 to fix and of course is has nothing to do with the power train so no luck. I will never buy another GMC vehicle in my life. I can put up with the small space inside, because I liked the oversized bed, but not paying $2700.00 with in a 6 month period give me a brake.

  Dont need a Diesel ! - 2011 GMC Sierra 3500HD
  By usapatrick - March 16 - 7:51 pm

  We shopped Ford and GMC. Bought the GMC because of build quality. Smokes the Ford in body gaps, paint, noise, warranty. Did the math on a diesel, no way for $8000. You dont see daylight for 500,000 miles. Pull a 24 enclosed with a car with the cruise control on in trailer tow mode. Absolutely love this truck. My local dealer found it for me. The paint is incredible, the interior is extremely quiet and comfortable with the leather bucket seats. The 40,000 mile warranty over the Ford has an untold value that could mean thousands. Installed headers & exhaust, K&N, Bosch Iridium plugs & Tayler 10.4 wires etc. No effect on warranty! Didnt even look at the Chevy as we own a10 GMC. Both Z71s.
