One problem related to air conditioner has been reported for the 2017 GMC Sierra. The most recently reported issues are listed below.
My air conditioning stopped working at only 51,800mi and just over 3 years old on my 2017 GMC Sierra 1500 denali. My mechanic said my ac condenser is leaking and needs to be replaced. He said it is a widely known issue but not a recall.
