CarComplaints.com 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.

problem #5

Dec 202012

Equinox LS 3.4L V6

  • Automatic transmission
  • 72,000 miles


Has not stopped. First replaced thermostat which seemed to help but the problem came back with revenge now. Starting again in September and has worsened now to point of putting in coolant every day. Today Friday, Dec. 13, 2013 the car actually stopped, shut down with my daughter driving in heavy traffic at an intersection. She waited about 10 -15 minutes, then went another 4 miles and the heat gauge was up again so she turned the motor off,. I arrived to put about 1 quart of Dex-Cool in overflow bottle. She then made it to a parking space.

Then about an hour later her dad drove and I followed close, till he got home, 9 miles. The gauge would go up, no heat in the car, and out the exhaust coolant was coming out. I read where it could be a gasket that Chev made that were not compatible with the type of coolant that we are now using. Stupid. Who is going to stop this before the car stops in heavy traffic and my daughter gets hit by another car, or she break down late at night and gets attacked. Who's fault is it going to be?

We put over 3,000 dollars in the car last year, tires, struts, thermostats (2) and extra checkups trying to find out what is wrong. Help before it is to late. The car has other wise been a very good car till last year.

My husband is a mechanic and he thought that there was a connection problem with the battery. We replaced the battery, still overheated. We replaced the sensors, the fuses, still overheated. In one afternoons time, we went through about 5 gallons of coolant, still overheated. Now he is in the shop working on it and replaced the intake valves and head gaskets.....hopefully that is the problem. I have been without a car for almost a month and I am so ticked at Chevrolet. Ever since I got this car 3 years ago, it has given me nothing but heartache. The depreciation in value is ridiculous! If I didn't still owe on my car loan, I would've pushed it off a cliff a long time ago. One thing is for sure, I will never buy another Chevy!

Frustrating not knowing whether it's really overheating or there is a short in the wiring. There is coolant in the car and everything has been checked several times.

I am frustrated with this vehicle that began overheating. I can't use the AC in 100 degree weather. It has engine coolant but will run hot if I turn on the AC.
