2015 GMC Terrain Owner Comments

If we use any climate control setting before using the defroster, then try to use the defroster, it will only blow cool air. If we change the setting to vent, heat or A/C, warm air will blow, but switch it back to defrost and only cool air blows from it. We could not clear the windshield of fog in a warm rain without turning the defroster all the way to hot (95 degrees). As this was in the middle of summer, it was unbearably hot in the car trying to drive. Took the car to 2 service departments multiple times, no code shows, so no fix for this. We are sent back home with car as it is. The problem was noticed just after buying the car in July 2015, and continues today.

Sept. 30, 2015 we bought a 2015 GMC Terrain from Buick GMC of Mahwah (NJ). There was 88 miles on the odometer. At night (in darkness) visibility is only accessible thru the bottom section of the windshield. There is a dark horizontal line across the windshield at approximately the half way point. It is black above the line-no visibility to the outside above the line. You can not see a safe distance down the road as visibility is restricted. Telephone poles, trees, objects, side roads, deer, obstacles, signs etc are not visible thru the windshield's top half. We drove it the first time at night Oct. 8. I was the driver, my husband passenger. Our seats were at different positions. Neither my husband nor I could see out of the top half of the windshield. The route traveled consisted of unlighted parkway and side road driving. On dark, non illuminated roads with no lights from other vehicles and street lights, we were not able to see anything above the horizontal line across the windshield. With low beams visibility was approximately 25-30 feet forward. There was no visible orientation above the horizontal line. It was black. High beams allowed a longer visual field but still no visibility above the line of the windshield creating a ¿tunnel vision¿ effect. Traveling up or down hill was particularly scary. Visibility was restricted to directly in front of the car. The 25 mile drive was frightening. There was no visibility problem during daytime driving or on highly illuminated roads at night. Oct. 9, 2015 (9 days of having the car) with 220 miles on the odometer, we returned it to the dealer without resolution. GM responded all Terrains are manufactured as ours and could find no problem as described. The car is unsafe and a hazard to us as well as others. We do not want to become a GM statistic.
