To whom it may concern: I am writing to notify you that I own a 2011 Chevy Equinox and take very good care of my vehicles. But I wanted to let you know that I have had three incidents in which the gas pedal sticks, and the vehicle goes up to 95 miles an hour. I have contacted the dealership and GM to let them know of this. They cannot explain why this is happening. GM just said trade it in. Well, that's a possibility and who says if the next person purchases it that this could happen to them. So far, we have been able to avoid an accident. I am wondering if anyone else has had this complaint because GM says no., I feel it has something to do with the cruise control that it has a computer glitz. Can you investigate this if anyone else has had this problem.

Catalytic converter issue, high pressure fuel pump, car shakes, balking while on idle or stop on red light, heavy chain rolling noise. Spent more than $3k so far but still comes with different problems every now and then. Engine light is always on and bunch of different codes show up while checking. Cruise control doesn't work. Wiper blades don't clear properly. Problem list can go on and on. Car shuts off by itself and it happened so many times. Engine power was reduced by itself and couldn't go more than 20 miles/hour on a highway with family inside the car.

I was turning left on a green light at the corner of argyle and oakleaf suntrust bank when the car slipped into neutral and I was stuck in oneway opposite traffic until I turned off the engine and restarted it and then was a ble to go into drive, I was almost in a serious accident with several cars. Then I was traveling north on hwy 295 and I had it in cruise control and I could not get it to quit until I turned off the engine. The power train was slipping after I had taken it to the chevy dealer and they said it was fixed but less than a year later it started doing the same thing as before, slipping, making loud scratching noises.rubbing noises and it smelled funny like it was burning but there was no fire.

Tl* the contact owns a 2011 chevrolet equinox. The contact stated that the cruise control was activated at 60 MPH when the vehicle exhibited an unexpected increase in acceleration. In addition, the engine rpms increased abnormally. The vehicle was towed to an authorized dealer for diagnosis where the technician was unable to duplicate the acceleration failure. The manufacturer was not notified of the defect. The approximate failure mileage was 27,300 updated 06/27/14

I put the car in drive and the engine sounded like an airplane taking off. I pulled out on the street, accelerated and noticed the needle go up to 4 RPM's at approximately 10 miles an hour. I took my foot off the accelerator and the car jolted and felt like I had been hit from behind. I accelerated again and the same thing happened, again feeling like I was hit from behind. The car is presently at my dealership but they cannot duplicate the problem. Today they are going to drive it for a good distance on the expressway. I had read one complaint on the equinox forum where someone was driving on the interstate with cruise control on and something very similar happened to them with the RPM sticking at 4 RPM's. I told my dealership about this and ask if maybe they are related problems.

Purchased 2011 equinox with 4-cyl engine specifically for the listed 32/23 mpg. I drive 30 miles per day back and forth to work, figured I would get around 24-25 mpg for in city highway driving. Instead, I have gotten no better than 21 mpg and usually less. I then drove from kansas city to oklahoma city for work, used cruise control most of time. However, it was windy so I figured it wouldn't quite be at 32. However, I was very surprised to only get 22-23 mpg for highway mileage. Very disappointing. The first time I contacted dealer (around 1,800 miles on odometer) service rep explained that the poor gas mileage was due to the change from winter blend gasoline to warm weather gas. As the poor mpg continued, around 3,000 miles I took car to dealer to have oil changed and at that time mentioned poor mpg. The service rep (different rep than previously) told me that the equinox had a 5,000 mile break-in period when it computes how the car is driven and adjusts for the driver's habits (how would that work if multiple people were driving the vehicle?). Any ways, I complained but was told it would get better. Now at 5,500 miles and still getting no better than 19-21 mpg. It should be noted that I generally run in "eco" mode. I have always been a chevy driver and will continue to be, but I will certainly research the cars better next time because I have noticed a lot of complaints about this same problem on several social type websites.
