  GM Quality - 2015 GMC Sierra 2500HD
  By Brad - July 5 - 7:50 pm

  only 1700 miles on the truck and had it in the dealer twice for an oil leak. The oil pan has surface cracking, apparently acceptable to GM as it is on every truck. The wax coating on the frame can be easily removed by a fingernail and already has rust coming through mainly on the joints as if it was not applied properly or the coating method is simply insufficient. I actually bought 2 of these trucks and both have had paint issues. the 1st truck had the 3.73 axle, which has a poor tow rating of only 9200 pounds or so. this information cannot be found on the website and the website shows you cant even get the 3.73 with the gas engine. sunglasses holder is oddly shaped and wont fit regular sunglasses. the manual shift mode doesnt allow you to shift up when coasting downhill or something. the truck always seams to be down one gear lower than it should be when coasting and tow mode is off. the passenger tow mirror is very poor for visibility and doesnt show the side of my trailer as my f150 did. the led lighting is cool but there are wires that can get snagged under the bed rails. ride is more firm than previous models which I like. Ipod playback is horrible. very slow to respond and often doesnt work at all. dealer said it works fine. air conditioner lowers for phone calls which is cool. towing uphill isnt very good. the truck bounces between 2 gears, one which is excessively high and the other is to low to maintain speed.
