2011 Chevrolet Equinox Owner Comments

problem #15

Mar 032011


  • 50,000 miles


Traveling 70 mph down freeway when suddenly my cel illuminated along with the traction control and anti skid lights. After carefully dodging a few vehicles, I pulled to side of freeway in heavy traffic and turned off my engine for a couple minutes. Restarted and engine appeared to run fine however the cel remained illuminated. I took the vehicle to a local GM dealer and they indicated a new throttle body was needed to remedy my situation to the tune of $340. The money part doesn't bother near as much as having to get to the shoulder in heavy 70 mph traffic. This imposed a very severe safety hazard to not only myself, but all occupants in my vehicle at the time.

The contact owns a 2011 Chevrolet Equinox. The contact stated that shortly after refueling the vehicle, the service engine warning light illuminated. The vehicle was taken to the dealer who indicated that the fuel pump assembly fractured prematurely causing a failure. The dealer diagnosed that the fuel pump assembly needed to be replaced. The manufacturer was notified of the failure. The approximate failure mileage was 106,000. Updated 1/20/16

Initially the issue started with rough idling of the car, engine ticking, and engine stalling. After indicating this to the dealership, they informed me that the ECM needed to be reprogrammed because the oil life indicator was not properly calibrated causing the system to think that there was more life on the oil than there actually was. The engine balance chain eventually broke while on the interstate (55 mph), due to improper oil lubrication. The fuel pump, water pump, and a few other items had to be replaced due to the damage caused when the chain broke. I notified the dealership once again after engine ticking/ rough idling re-occured and they indicated to me that the engine ticking during startup was normal. The engine ticking progressed to becoming a constant noise. I noticed that when I took the oil in for an oil change, approximately 2000 miles in, that the oil dipstick would come up completely dry. This indicated the vehicle was experiencing an excessive amount of oil consumption. I took the vehicle to the dealership who indicated that pistons had to be replaced and the exhaust manifold was cracked. This indicated that the engine was observing some excessive amount of heat most likely due to the oil consumption issue. During these issues, no service engine light ever came on. The car had to be taken back to the dealership after the service engine light came on which indicated that the cam shaft actuator solenoids and catalytic converter needed to be replaced. The catalytic converter most likely failed due oil seeping into the exhaust which coated the ceramic substrate & the excessive heat experienced by the engine (as indicated by the cracked manifold) damaged the ceramic substrate. Oil consumption leads to excessive heat from the engine which can be a fire hazard. Engine stalling due to oil consumption leads to crash safety issues.

In February 2015 the throttle body was replaced/repaired due to reduced engine power and stalling while driving. Although no longer under warranty, Chevrolet picked up the repair cost. Since the repair, there has been hesitation in acceleration. More recently there has been loud engine noise (sounds lile a diesel engine), rough idling at a stop & hesitation when turning off the vehicle. It sounds and feels like the engine is going to fall out. The check engine light has come on 2X. I will be scheduling service.

Upon leaving the home driveway, as the car began to accelerate, the "check engine" light came on, and the information station flashed the warning "stabilitrac / power reduced". the car was still drive-able, but would not accelerate past the first transmission gear. After getting the vehicle back home, I restarted it, and the same warning was displayed in the information station. The vehicle also began to idle very roughly and emit thick black smoke. All indications from internet sources point to a bad throttle body, which was later confirmed by the car dealership. According to the massive amount of complaints about this part, it has a very high failure rate in this vehicle. However, Chevy refuses to cover this part as part of their power-train warranty. The "power reduced" condition caused by this part failure is a very dangerous thing to have happen to you if you are turning in a busy intersection or on an interstate highway, and if something is not done, there will be injuries or fatalities because of it.

Equinox 6-cyl

  • 18,000 miles
My wife purchased a 2011 Chevy Equinox with a window sticker stating a four cylinder engine. It had 1800 miles on the vehicle when purchased. We took the vehicle in to have the oil changed and found it has a six cylinder engine. How is this possible and who should I speak with at GM. I'm very concerned because of the terrible gas mileage and a six cyl engine was not shown on the paper work?

This vehicle has never gotten anywhere near the advertised epa estimated gas mileage. I have over 20000 miles on it now and have only averaged around 23 mpg on the highway in eco mode. This really should be considered false advertising. I bought the vehicle mainly because of the estimated 30 mpg. Really disappointed in GM at this point.

Sensors for the throttle control went out causing reduced engine power in sub zero weather at a stop. This made for hazardous driving in rush hour traffic as it was difficult to get the car above 15 mi per hr especially up any slight incline when the normal speed limit was 45 and every one is annoyed they are being slowed down.

Equinox 4-cyl

  • 20,529 miles
I have had many problems with my 2011 Chevy Equinox that started occurring about a year after I purchased it. The main concerns are the engine noise and how rough it runs, feeling as though I am being rear-ended in traffic (when moving forward from a complete stop it lurches forward, giving the feeling of being hit), rough start up (sounds like an old car at times) and the car stutters when accelerating (almost feels like it wants to stall out). I do not feel safe in this car now and have read that many others are experiencing the same issues. I have taken it four times giving them the same description each time at which they state that they cannot replicate these issues. They keep my car for hours and do nothing to it. I am a single mom so I can't leave my car without it causing major issues for me as I have to take my son to and from school. I received a letter from GM stating that there is an issue with the fuel pump and engine balance chain and describes what my vehicle is doing now-I believe I have engine damage and I am worried that I will end up breaking down on the side of the road at some point or worse stall out and end up in an accident! in addition to the engine problems there is a problem with the defroster, it just doesn't clear the windows fast enough, on going problems with the stereo (makes a static, distorted sound with the usb port) and the drivers side squeaks because it rubs up against the middle console. It is very frustrating because the problems are intermittent. I am hoping that enough people complain about this safety issues with regard to the engine and cause GM to deal with it appropriately! we should not feel afraid that our new car will break down on us, especially with our children in the vehicles!

Equinox 4-cyl

  • 18,719 miles
When vehicle was pulled into our garage, a strong smell of gas was noticed. Still under warranty the fuel line was replaced by our dealer. The vehicle mileage was 18700 miles. We bought the vehicle in February of 2011. The vehicle gets parked in our garage every night. We are concerned that a vehicle with so little mileage and at so young an age could have such a serious corrosion problem.
