The climate controls use GM’s standard pushbutton layout, which is generally no bad thing. Separate zones for the driver, front, and rear passengers means that nobody complains. It also does a very good job of cooling the Tahoe’s big cabin, and considering our test vehicle’s dark exterior and black interior, that’s quite a feat. The buttons are also too small, meaning you have to commit to muscle memory just about everything if you don’t want to stuff your Tahoe while trying to cool it off. Another GM quirk is the recirculation mode, which defaults back to fresh air every time you shut the vehicle off. It’s really annoying if you prefer to keep outside smells outside.
