Got my 2010 equinox in Nov 2010, new.
I didn't have the engine problems early. However in the last year, I have been back to the dealer a number of times. We live far from work, so it already has 110,000 miles, that means no more warranty and more out of pocket costs.
The latest item to go is my stereo.
The stereo includes the navigation, clock, radio, iPod hookup, Bluetooth, backup camera. Cost from the dealer to replace $1300! Dealer suggested I get an after market radio...but couldn't tell me if all the other stuff would work.
Probably trade it in very soon. My last car, 1997 Audi a4, just kept on going...engine finally gave up at 225,000 and after 13 years. Now that's reliability.
