I had my 2017 GMC Terrain denali for two years and have already experienced two serious issues. Issue #1-I noticed a burning smell, grinding noise, and hesitation when driving. I brought it to the dealership where I bought it and was told that there was a factory defect which caused something inside my transfer to bore a hole through it. Dealer could not get the part for 2 weeks. It was covered under my warranty. A month later while getting an oil change at a different auto shop, I was asked if I recently had work done only transmission because the entire thing was loose and moving, and the car did not drive right. I was told it was not safe to drive. I brought it back to the dealership and was told that they couldn't find anything. They tightened the bolts on the transfer case and charged me a $60 diagnostic fee (for their error). Issue #2-at 63,000 miles my wipers stopped working while I was driving at about 30mph on a busy street in the pouring rain (very scary). I brought it to the dealership and was told I needed a new wiper transmission and would cost $318 because my car was not part of the recall. I expressed concern that my 2yo. Car has now had two serious safety issues and was told 'cars have so many moving parts and pieces that it's a wonder more things weren't wrong with it'. I do not feel safe driving this car and the service manager was condescending and couldn't care less. GMC needs to do something before somebody gets seriously hurt or worse.

The vehicle's climate control system does not function properly. The air is not properly distributed out of the available vents. At times, air is only distributed through the floorboard vents. Other times it will only be distributed via the defroster vents. Recently, the car windows became completely fogged up while driving on the interstate at night. I attempted to use the defroster, but all air was distributed to the floorboard, which had no impact on the windshield. I had zero visibility and had to pull off on the side of the road. Up until this incident, the problem had been restricted to a lack of comfort, but it has now become a safety risk. GMC has been previously made aware of the problem and I was informed GMC engineers were aware of the problem but did not have a way to fix it.
