Intake valve and valve cover gaskets blown due to corrosion by dex-cool over time. Also had blown head gasket repaired 10/16/2014 due to same problem.
I bought my Equinox in October of 2015. After having it just 6 months and driving it approx. 3,000 miles the head gasket blew. I bought the car with only 70,000 miles on it. I took it to a local auto body shop, and they told me I would need a whole new engine (they suspected stop leak was put in to mask the problem before I purchased the vehicle). They are quoting $3,400 for a refurbished engine (that could run into the same issue) or $5,900 for a new engine. Gm has been no help at providing any type of assistance. As I've done more research, I see countless other cases of this happening with low miles. We have always purchased gm vehicles, as my husband's stepdad and uncle were both gm employees. My faith has now been shaken in the company, and I will not be purchasing another gm vehicle anytime soon.
