Two problems related to engine stall have been reported for the 2012 Chevrolet Equinox. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2012 Chevrolet Equinox based on all problems reported for the 2012 Equinox.
Equinox very suddenly started running roughly and making a "knocking" noise from the engine and acted as if engine wanted to stall while idling. Low engine oil light came on, we stopped for oil and added oil. Started Equinox up, low engine oil light was no longer on. Drove the Equinox for approximately ten (10) minutes when it made a horrendous shuddering noise, engine warning light came on stating "stop engine now". We pulled off to side of highway. End result: the engine was blown and needed to be replaced at cost of $8,000. 00, five months after the 5 year warranty expired. Equinox only had 64,000 miles on it and oil had been changed regularly including in late August 2017. Subsequently came to learn that gm has many engine and engine oil related issues with Equinoxes dating back to 2011 at least. Our Equinox had not been subject to any recalls.
At times it seems like the transmission doesn't shift properly when starting to accelerate. It's as if it's not sure what gear to go into. Currently I have an engine light on and it stalls frequently. If I slow down or start to accelerate it will stall. I'm afraid I'm going to get rear ended by someone! it also blows out white smoke from the exhaust. I seem to be adding oil more often than I should.
