I purchased a 2016 Yukon denali brand new from the dealer in October 2016. Since this time the vehicle has been in the shop 5 times. The first time was due to front driver side door not being fully aligned with the front fender. This issue was not resolved as they said it would "most likely mess the vehicle up further". In February of 2017 my Yukon went back to the dealer for service involving the power running boards not deploying and control panel not illuminating. The control panel was blamed on a software update. While at the dealer the service manager stated that "gm put out this software too early". In may 2017 the rear dvd player went blank and stopped working. These two issues were both covered under warranty. In November 2017 the radio started to "freeze" and wouldn't change channels. I was told this was a software update issue and I needed a new hmi ($500) and will not be under warranty as I now have 40,000 miles. In December 2017 my Yukon went back to the service department due to air conditioner failure. After reviewing on the internet this seems to be a common problem for this vehicle. Apparently, there was a special bulletin the consumer isn't aware of until it breaks, so it was also covered; however the blower motor ($377) that broke due to this issue wasn't covered. I contacted gm customer service and filed a complaint with a supervisor. I was told there is nothing they can do due to my Yukon being out of warranty, and when they build these vehicles "they do not know how long parts will last". In my opinion this is unacceptable especially for a $75,000 + vehicle that is only 2 years removed from the manufacturer. I have owned 3 gm products (tahoe, Yukon, and now this vehicle) and I will never buy another gm product.
