The engine light comes on after a warning that the gas cap is loose. I have tightened and replaced the gas cap but still get the light. My mechanic confirms that it is the gas cap.

So here we go again. 2012 and ANOTHER powertrain repair! So yeah yeah, it's covered under the powertrain warranty but what is it doing to the resale value of my car? I have a 2008 with 140k miles on it and I feel safer in THAT! I will be on the phone to Chevy next week to give them a piece of my mind. Will definitely update! BTW, they had the car a WHOLE WEEK before they freaking figured out exactly what was wrong with it!

Equinox 4 Cly

I am truly disappointed with this vehicle it is a decent year with low mileage and the Chevy dealerships I have called have offered little to no help at all. I wish I could return this vehicle and I will NEVER buy another Chevy as long as I live.

Equinox LTZ 2.4L

  • Automatic transmission
  • 12,000 miles

Engine light comes on and on and on, which when on other things don't work, ie cruse control, remote starter. Mechanics say this is not a random experience and no known fix as of yet. The mechanic say it's the throttle body and bad gas. My truck doesn't have this problem. Seems on 4 cylinder motors there is a lot of gunk that builds up on the valves and also causes less gas mileage, went from 32 mpg to approx.. 27mpg highway. The only good thing is that it happened before the warranty ran out. It's in the shop right now, again. The dealership has been fantastic so far, but this is the last time for them to try to fix it. We also had the dash board control lights go off when we were driving.

I have taken this car back to the dealer every other week because of the check engine light keeps coming on and its starting to annoy me because they can't come up with why it keeps coming on they keep telling me its nothing but its cold now and my automatic starter won't work as long as the light is on. I tried all brands of gas and noting seems to help and its back to the dealer again the light has come on again.
