EXTERIOR LIGHTING, VISIBILITY/WIPER
While driving on the highway at night during mixed precipitation/icy conditions I noticed I was loosing visibility. I had to pull over on the highway to see if my headlights were on. I discovered they were completely covered in 1.5-2in of ice. The entire front grill of the truck was covered in ice. I had to chip off the ice on the headlights so I could see. I had to pull over three times during my 2hr drive to scrape the lights just so I could see! The headlights on the 22 model have shape, not straight or a smooth curve like prior models, which is part of the problem. Although, it was strange how the entire grill was covered in ice. I have always owned GMC or Chevy trucks and have never had anything like this happen. I wish I took a picture to send in but I didn't think of that in the moment. This is absolutely a safety hazard. I hope in the near future there will be a recall to have this issue addressed.

ENGINE, SERVICE BRAKES, POWER TRAIN
The throttle body gets stuck wide open after the eninge gets up to operating temperature, it will give some warning with the throttle like on off throttle use and no codes show up at all. The risk of everyones is in extrem DANGER. The break are to soft and well not stop unless you put both feet on the break pedal down to the floor. Tranismission can NOT figure out what gear it needs to be in way too many gears and horrible fuel mpg for the 6.6L Duramax L5P. None of the GM dealership will look at the truck unless there is a code or it is happening right there when they look up the trucks VIN.

ELECTRICAL SYSTEM
We recently noticed a persistent Trailer Braking Alert. When the Alert occurs it changes the center display and it plays an audible tone repeatedly. Both of these are a distraction to the driver. We do not normally pull a trailer, and when we do it is not one controlled by the trailer braking system. However this limits the vehicles usefulness since this would disable trailer braking of one were connected. This has been demonstrated to the dealer and we are awaiting resolution.

ELECTRICAL SYSTEM
The front driver side window won’t roll down or engage; the a/c blows warm/hot on the drivers side vents; the stereo system continues to, “Glitch” changing stations, displaying other information without the screen being touched. These often cause discomfort by not operating properly. The dealer did not suggest any concerns upon my purchasing the vehicle. Vehicle was never taken to a certified GMC dealer for these issues.
