I've had 15 vehicles or more in my life. What I've experienced with the Equinox is non-stop since 9900 miles. I could have purchased this SUV twice over the lifetime of the vehicle for what it's cost me. (feels like anyways) I'm actually lucky I've only done the head gaskets once so far on this motor, and that happened around 40,000 miles even though I babied the crap out of it and did all maintenance. That list above is not a complete list. You can defend the GM all you want but I am knowledgeable and baby my cars with all maintenance that is needed, so your comment isn't just here.
To the person with the 2.2L Sunfire, they are known to never die. Just like the 3.0L V6's Ford uses in the Escapes and Fusions. They are rocks.
But the Equinox (2005-2007 years) is a lemon across the board. In 2008, they switched to the newer 3.6L V6 Powertrain on many, and in 2010 they went to the 2.4L 4 bangers.
