When the vehicle starts in the morning for the first 15-20 seconds you could hear a load rattling noise then the noise goes away. I had change the oil from synthetic to regular 5w30 because when I drained the crank case the only thing I had left was 1. 5 qt, im trying with the regular oil to see what it does . I hear that many Equinox owners have had the same problem with oil consumssion. I would like to reported ,maybe its a problem among these vehicles owners.

Bought vehicle used with about 30k miles on it, at first oil change was told oil was low, this continued over the next several changes, a few times it was found to be completely out of oil, no oil leak was found, at 39k miles balance shaft chain had to be replaced, at 55k miles my check engine light came on and my car almost cut off on me while I had my infant son with me, the cam shaft had to be replaced, 56k they replaced pistons, rings, fuel pump, and timing chain due to using excess oil, a few months later my air compressor had to be replaced and now my transmission is leaking. The car has a little over 70k miles on it. Also have been complaining of a rattling noise coming from the engine since I bought the car, I was told several times by the dealership that this was normal however I was told by someone at the Chevrolet home office that this was not normal, I also drove another Equinox while mine was in the shop being repaired and it did not make this noise. Dealership has be notified of all issues with the vehicle as well as the home office for gm.

It started with the check engine light would come on and the stabilitrak light coming on sometimes. And you hear a rough idle. And a horrible rattling noise was coming from the engine while parked and. When I drove the car when accelerating it sounded worse as if I was driving a diesel truck. And the car would stay on for about 2 to 3 seconds after I turned the car off. So I dropped the car off at the dealer they checked it with a scanner and they got the p0172 - too rich error code. And they saw for themselves the car stayed on after turning off the car and the rattling noise it was making. After 2 days I picked up the car coalitionâ??t hear the rattling noise as much. You could still hear the rattling but very slightly the check engine light was off. After a week driving my car you can hear the rattling noise very, very little. They fixed the rattling noise somewhat it was covered ( by power train warranty) however both the check engine light and the stabilitrak light came back on. And the car still would stay on for about 2 to 3 seconds after I turned the car off. And sometimes when I start my car it would rev up has if I step on the gas pedal and then it will drop to normal. All issues were not resolved still having problems with check engine light stabilitrak light on and the car staying on. For a few seconds. After turn off the car. Took it back to the dealership now they are saying they found that it is a problem with the high pressure fuel pump and the body throttle. Not functioning correctly. This may cause gas to leak into the oil. I did some research this is a common problem with the 4 cyl Equinox. The dealership said the repair would not be under the 100,000 mile powertrain warranty.

When starting the vehicle at any time the engine idles very rough and rpms fluctuate significantly enough that it shakes the vehicle. Engine noise is very loud, even for a small direct-injected engine. When driving the throttle is slow or jerky to respond and the engine noise increases. At different rpms a rattling sound comes from the engine compartment, as though something is loose and will fall off. I have had this vehicle at our chevy dealer several times for this issue and most recently for the vehicle not shutting-down when powered off. The high-pressure fuel pump was replaced based on gm bulletin but nothing was done about the loud and obscene engine noise. Dealer stated this was normal operation although bulletins exist in gm system for timing and valve-train issues and repairs. I am concerned that the engine will simply quite one day under normal operation. Planned obsolescence at 100,001 miles? I will be taking the vehicle to another dealer very soon to try an remedy the situation and understand my concern and work with me to correct issues.

When stopped at a stop sign or red light sometimes the engine tries to cut out, and the car jerks like it is trying to stay cranked. I have a friend that has a gm terrain and hers does the same thing. When turning there is a knocking in the steering. The speakers have a rattling sound like they are busted, but it doesn't do it all of the time. I took my car to the dealer, but of course they couldn't find anything wrong with it, the car now has 23,000 and it still hasn't been fixed. (this has been going on since September of 2011 when I bought the car).

I bought my 2011 Equinox in Dec. 2011. About 4 months later when I started the car there was a rattle noise which sounded like the starter is not engaging right. I told my dealership about this but they could not duplicate it. I have read other complaints, so I hope gm will investigate this problem. I hope this does not mess up the engine. I have been driving 46 yrs & never have had this problem before. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
