What Owners Say
"Technician told me that the compressor came apart internally and required evaporator and other components to be replaced"
Anonymous, GA (2011 GMC Terrain SLT 3.0-L V6)"replaced not cooling."
Marvin S., CA (2011 GMC Terrain SLE 3.0-L V6)"Replaced compressor twice. Last one broke after 13 mnths, so no warranty."

Per S., HI (2011 GMC Terrain SLE 3.0-L V6)"Replaced compressor and condenser at the same time in Aug 2017. Had to replace the new compressor and the original dryer in May 2018"
Sandie L., CA (2011 GMC Terrain SLT 2.4-L 4 Cyl)"The compressor developed an internal failure which caused metal to be distributed through the entire system"
Anonymous, GA (2011 GMC Terrain SLT 3.0-L V6)"A module that controlled damper operation failed"
Anonymous, NY (2011 GMC Terrain SLE 2.4-L 4 Cyl)"On a trip to visit family 250 miles away in August, during a heat spell, the air-conditioning and automatic climate control went out. The fan would not blow, no cold air would come out, and it created a drag on the motor - severely impacting performance and mileage. I called GM, however, the representative from my local dealership could not be bothered to help us - he told us they were too busy with other problems. This happened just after taking the vehicle in for an oil change and air-conditioning system check-up."
Anonymous, OH (2011 GMC Terrain SLT 3.0-L V6)"Extreme heat followed by extreme cold coming through the vents. Had entire climate control module replaced"
Anonymous, PA (2011 GMC Terrain SLE 2.4-L 4 Cyl)"Car would not cool"
Anonymous, FL (2011 GMC Terrain SLT 2.4-L 4 Cyl)"Lost defog-defrost capabillity in 25^F damp weather having to stop on the freeway many miles from home on a Sunday. Dealer blamed this loss on a criter caught in the duct and jambed the mode actuator, plus a software update"
Floyd D., MI (2011 GMC Terrain SLT 2.4-L 4 Cyl)"When in automatic climate control, sometimes cooling system does not work properly. Warm air circulates and system must be turned off completely for a few minutes and then turned back on to allow cooling system to engage"
Brandon C., AR (2011 GMC Terrain SLT 2.4-L 4 Cyl)"Accuator in the temperature control failed, was about $200 to fix, works fine now"
Lynn L., PA (2011 GMC Terrain SLT 3.0-L V6)"The blower started losing power and slowly reached a point where cool air wouldn't blow out on a hot day"
Anonymous, GA (2011 GMC Terrain SLT 2.4-L 4 Cyl)"The HVAC controls are problematic and, I believe, are fragile or have poor workmanship"
Anonymous, MD (2011 GMC Terrain SLT 2.4-L 4 Cyl)"replaced not cooling."

Per S., HI (2011 GMC Terrain SLE 3.0-L V6)"Must replace evaporator beacause its leaking."
Anonymous, HI (2011 GMC Terrain SLE 3.0-L V6)"Seems like it takes forever to start throwing warm air then never warms the car sufficiently in very cold temps"
