I have had my car for 2 years and in two years I have had to get the catalytic converter replaced also the tensioner belt the O2 sensors and a few other things replaced. My chevy Equinox is a lemon and a few other people I know has said the same thing I wish I never purchased this car and I'm stuck with the $14,000 lemon that I can't get rid of.

My 2011 Equinox suddenly lost power while driving and could not control the vehicle in traffic. The vehicle would not start, but would turn over. Fortunately I was able to push it off the highway and tow it home. I then had it towed to dealership in brockport NY (spurr gm dealership). It took 3 weeks to diagnose and repair. The root cause according to the mechanic was that the original factory tensioner to the timing chain failed and the engine went immediately out of time - causing immediate failure of the vehicle and hence control on the road. The engine needed costly repairs of $2600 which is fine (my families life is worth way more) the factory original tensioners evidently fail regularly because they are hydraulic and the intake holes to the tensioner plug easily - chevy evidently repairs with an improved part that has a wider intake port to prevent clogging. This is a safety issue as control of the car can be lost immediately, without warning and it is difficult to control a car with such a failure causing injury or death of the driver occupants or anyone in other nearby locations to such an event. Chevy does not consider the common failure a "safety" problem rather a "mere" mechanical problem. It is worthy to note the vehicle was otherwise in good shape, well maintained and used synthetic mobil-1 oil - changed 2 weeks prior to such event. The dealer repairs noted no other mechanical issues to the vehicle related to poor or unperformed maintenance.

While driving on the highway the check engine light came on. Immediately in the message area two message were displayed - "reduce engine power" and service stabitrack soon". Immediately the vehicle would not go over 3000 rpm and 50 mph. Within a mile the engine lost all power (luckily this was as I was hitting the exit ramp off the highway). After waiting for a few minutes I was able to fire it up but the errors returned. I limped the vehicle home and had it towed to my local garage. My mechanic indicated there were 9 error codes when he looked with his scanner related to fuel pressure, cam sensors, and motor timing. Furthermore, since I was due for an oil change, he drained the oil pan and saw I was nearly 3 quarts low on oil. This is puzzling as (1) I just checked the oil two weeks ago and, while a bit low, was in operating range and (2) the low oil pressure light never came on. After reading other complaints on this and other sites this seems to be a common occurrence. So now I have a vehicle with 63,000 miles that my mechanic says has significant engine damage (timing chain tensioners, cam sensors, fuel pump). This is very difficult for me to believe since there was no warning lights that came on for low oil and at this relatively low mileage. My only alternatives are to pony up for the parts (and hope the pistons/seals are undamaged) or replace the motor. I also think its quite dangerous for the motor to just cut out like this without more advance warning (I was lucky I was already getting off the highway). Needless to say my confidence with gm is pretty much gone.

The vehicle was in motion, accelerating on a freeway entrance ramp. As I was merging, the engine lost power and started a loud knocking noise. I could not accelerate, started slowing, but was able to get to the shoulder. I had the vehicle towed to the nearest chevy dealer, where a quick diagnosis was that the engine had failed, and would have to be replaced. This engine has had 2 warranty repairs related to oil issues (8/2011 and 8/2014). In both cases the timing chains, tensioner, gaskets and seals, etc. Were replaced. Also, in 2014 there was a recall to reprogram the oil life monitor. There was a recall letter in September, 2014 regarding excessive engine oil use due to piston ring wear caused by the previous issues. This condition was to have an extended warranty of 10 years or 120,000 miles. I blame the engine failure as an extension of these oil related issues, while chevy says 'no".

Failure Date: 01/09/2016

Was driving the car at approximately 40mph when the engine shook and slowed down to about 30mph and the rpms shot up to 5,000. I just got the vehicle back from the dealership and they had just replaced the balance shaft chain and tensioner & high pressure fuel pump to hopefully remedy the same problem. The vehicle was purchased certified pre-owned with apprx 52k miles. 11/27/15. I first brought the vehicle in on 12/11/15 and it was retured after 4 days and not being able to "recreate" the problem. I returned the car to the dealership on 1/4/2016 for the same problem which occured on new years day. I just got the car back after repairs on 1/7/16 and now two days later the problem has again occured. The last time in the shop they also could not "duplicate" the issue after driving apprx 50 miles, but I pointed out that the oil was very dirty and smelled like gasoline which they checked and confirmed and did the repairs of the fuel pump and balance chain. The engine issue is still not resolved and I will be returning the car to the dealership again on Monday. I just got plates today because my 30 day tag just expired.

Purchased car from Toyota of rockwall in Jan 2015. In July 2015 started having issues with shift not coming out of park, sometimes the problem would not duplicate, so I had to take it back to the shop multiple times. Initially took car to stonebriar chevy (frisco, TX), who replaced the battery. The issue occurred again - I took it to ntb (rockwall, TX) & had various parts related to shifter assembly replaced. I had it there a few times with the same issue. I then took it to britain chevy (greenville, TX) 3 times between Nov & Dec 2015 - the car showed error codes p0326, p0324 & p0014. The following repairs were made, some covered under special coverage warranties: replaced transmission shifter assembly, engine balance chain, tensioner, gasket, pump, pipe, seal gasket kit, 3 bolts (various part #s), filter, gm dexosi 5w30, timing chain kit, camshaft actuator & loose connection at ecm. Again in may 2016 had issues. Took car to lakeside chevy (rockwall, TX) & received the following error codes: p0324, p0016 & p0017. It was determined that there were oil consumption issues (covered under spec cvg warranty), but that a bolt unaffiliated with a spec cvg warranty or any bolts replaced in the past had come lose, causing timing chain to hit engine over and over, resulting in engine being ruined and needing full replacement (quoted $6k for this). I have been arguing that this should be covered under spec cvg warranty #14159 or 12313 since it is related to timing chain, etc. , but was told the bolt that came lose is not one that is listed under any spec cvg warranties. I believe this is most definitely a safety issue. The check engine light did not come on until the week I took it back in the shop in may, yet the mechanics have told me the bolt has been loose and chain hitting my engine for quite a bit longer than that.

I had been having oil consumption problems, like many other owners of 2010 Equinoxes and was undergoing an oil consumption test. Was driving on I-81s on a 500 mile trip. When I started the car after stopping for gas, it idled very roughly. Foolishly, I got back on the interstate, thinking that maybe a higher speed would help. The car would not get up to a safe speed and completely stalled out about a quarter mile from the exit, leaving me stranded (by myself) 150 miles from my destination. Was towed 70 miles to a dealership who replaced the timing chain, tensioner and fuel pump. This dealer stated the problem was due to low oil level as well as dirty oil. I incurred an unexpected $1200 bill and was without my car for a week. My home dealership replaced my engine 2 weeks ago and I received reimbursement for the repair bill. I am pleased, presently, with the response from gm, but it required persistence. Although I have had my present problem rectified, I'm reporting this problem as many, many others have been experiencing this same problem with varying responses from gm. I've also experienced some shifting problems as well, but the engine problem took precedence, so I'm waiting to see if the transmission problem continues!.

2010 chevy Equinox keeps knocking, dealer replaced timing chain twice and the timing chain tensioner twice and still has the problem. It now shuts off while driving and shakes and mis-fires when cold in the morning. Dealer cant seem to find anything wrong they said the 4-cyl engines are problematic and nothing can be done. I have called gm and they haven't offered me anything. I have videos of the car having problems, they said that's not good enough.

Failure Date: 06/17/2011

Brought vehicle into first dealer for loud engine noise at low speed (1 to 10 mph)06/17/2011. Dealer said it was the fuel injectors and said they will install an insulator to quiet the noise. Installed insulator problem not resolved 7/1/2011. Brought it to another dealer for the same noise. Dealer found noise from timing chain7/26/2012. They replaced timing chain and tensioner8/31/2011. Problem seemed to be resolved. 8 months later the noise is back. Gas mileage and power has decreased. Dealer suggested running a solution through the engine to clear out carbon from low octane gas. Dealer applied solution and told me to run two tanks of super unleded to resolve the problem 4/6/2012. Noise is still there after 2 tanks of super unleaded 4/13/2012. Going back to the dealer in a week 4/20/2012. Contacted gm in detroit to express my anger. 4/13/2012. .

I started hearing a knocking noise at 28000 miles. Had serviced but after several miles noise started again. Noise continues so service is needed(10-2-13). I had several gaskets, seal, bolts,fuel pump(which was leaking raw fuel into inside of engine), balance chain, timing chain, guide for timing chain(which guide and debris fell in oil pan), and two tensioner replaced as well as oil life monitor recall update. Here I am nearly 3 months later and my 2010 Equinox is in shop(12-31-13) and can't be driven do to loud noises, lose of power fuel and oil, as well as stalling and check engine light being on continually. I did extensive research and found thousands of people with same year and model Equinox as mine to be having same problems as mine at same mileage. I found that the engine needs to be replaced because of damage done by leaking fuel pump. So no matter what work is done or what is replaced problems still keep happening because damage is all ready done to inside of engine and the entire engine should be replaced. Please help, this is a major problem that effects thousands and nothing is being done for us owners. Those who are lucky to get their engine replaced don't get an accurate warranty and after several miles the new engine starts having the same issues. Please help!!.
