Blown head gasket at 65,000 miles. Was driving on the freeway when it happened, car lost power. No indication of any issues before, no check engine light, no other warning whatsoever. Seems to be a common problem among 2005 & 2006 Equinox's since I was informed of how common it is from the lady at the bmv. . . . I kept asking my chevy dealer how does a vehicle with only 65,000 miles blow a head gasket and somehow I doubt this was the first time they have heard of it.
While driving at aprox 45mph the engine just stalled. No warning no sputtering just dead. Both engine lights came on the check engine light and one with the x thru the engine. After aprox 30 seconds it started back up and was fine. This has happened intermittantly at different stages of driving and various speeds. On 12/28/11 it happened to us 3 times while out. I am leary of taking it to the dealer close to us as they recently did a brake job that I have had to take back 4 times and am again having symptoms of needing brakes. I have no faith in the dealer.
