Print this page Notes: The 2006 Equinox is plagued by a heating problem, as in the heater only blows cold air.

The reported cause of this problem is a small door, known as the air temperature blend door, which allows air to flow past the heater core. This door has a plastic connecting shaft to an electric motor and the shaft is prone to breaking after a few years. The problem has a typical repair cost of over $800.

The 2006 Equinox also has a number of reported problems ranging from the key getting stuck in the ignition, to failing speed sensors, and trouble starting the engine. All in all, this car sounds like one worth avoiding.

I was traveling at a speed of about 10-15 miles per hour, conducting an investigation pertaining to my job, when I began to hear a loud clicking sound coming from my engine area.I immediately pulled over and turn the vehicle off.after letting the engine rest/cool for about 20 minutes, I restart the vehicle, at which point the amber oil alert lamp activates, and then turns, mind you, I had just had an oil change approx 700 miles prior to this occurring.the clicking began to subside, and, since the amber oil alert lamp was no longer on, I figured it would be a good idea just to get it back home so the oil could be checked the next morning.suddenly, when I arrive home, and get ready to turn the vehicle off in the driveway, the amber oil alert lamp re-activates, the engine, again, clicking.I turned the vehicle off.the following morning, I contacted a G.M. dealership and described to them what had occurred.they told me I should bring the vehicle to them to be inspected; however, the soonest I could get in was about three weeks.instead, I contacted a local oil-change store and had the oil changed and the system checked out.a little ways down the road, about 1,000 miles into my oil change, the amber oil lamp comes on again, still clicking, but not nearly as much as before.I pull into my driveway a few miles later and start hearing a "clunking" knocking sound coming from the engine area, at which point the red oil lamp came on.I called the GM corporate customer support, whom after I described what was going on, stated to me it sounded like a major engine problem relating to oil issues.I asked what General Motors could do for me, and she stated "I am sorry, [xxx], but the Equinox, prior to the 2008, was not manufactured with any type of power train warranty whatsoever.I am sorry but there is nothing we can do to help you."now I have to replace my engine due to major damage!

We have a 2006 Chevrolet Equinox that has continuously had an electrical short in the wiring harness that deactivates the gas pedal accelerator. When it happens you can only move the vehicle with the pedal floored at 1 mile per hour which is very dangerous when you are on a high speed highway with no other cars around as you can not move out of the way of high speed vehicles that may be approaching. We have had it into the dealer three times and it continues to happen again intermittently as to the point we feel it is unsafe to drive. We have filed a complaint with Chevy and they refuse to take any responsibility. We are afraid to take it on vacation as we could be stranded.

Truck lost speed without warning while driving in traffic. Engine cuts off while driving. Truck can be working one minute and you park and come back and nothing it would start and have to be tow and this has happen to me three times in the last 5 months. The elec system always have something wrong with it. Running at 55 mph and a semi-tractor trailer behind you with your three small grand children in the back and the truck just lost it speed with no warning is a frightening thing to happening. I have replaced the battery, the started, and now the lower cooler fan is out the elec. System just keep breaking down back to back and I hardly even drive it only to doctor appointments and to do my shopping.

I have a 2006 Chevy Equinox 23,000 miles. During very heavy rain I lost all acceleration and the car slowed down. I was on the highway so I was very lucky to not die because traffic was light and there was room for me to get right (slowly...) the rain got lighter and acceleration resumed.

problem #1

Oct 012006

Equinox 4WD 6-cyl

  • Automatic transmission
  • 5,000 miles
Vehicle make loud roaring noise during hard rain, and lost power. The vehicle acted like it was hydroplaning, however, they roads were puddled enough to cause such an effect especially at 5,000 miles, brand new tires. The vehicle sounded like the transmission was grinding, and after punching the gas, had no response. I pulled over and restarted the car, it did not fix the problem. The problem went away as the rain subsided. I don't have the exact date of the incident.
