“I have a 2005 Equinox and had to put the car in the shop 3 times now in 3 weeks! The thermostat went out, then the radiator had to be replaced, and now they say the head gasket needs to be replaced. Bubbling sound can be heard when you take off from a stop. I'm also having problems with the brakes making acting strangely.. The front shakes when brakes are applied.”
NHTSA complaint #10397450, filed 2011-04, 74,000 miles“I have a 2005 Equinox. It started overheating and losing coolant, though there was no leak underneath. Brought it to my mechanic who told me I had a blown head gasket. I emailed chevy but because its not at a dealership refuse to help any with the problem. I don't understand how something so major can break on a 3 year old vehicle.”
