2015 GMC Terrain: headlights failing or too dim

Filed Dec 31, 2023 · Electrical, Lights · WI

The blower fan for heat In my vehicle was replaced in October 2022, recently the Defroster will not engage and it is vital to winter driving. The mechanism that switches between which vent to blow out air was replaced and the Defroster will still not engage, rather it comes out of the heat and face vents. Shortly after the Defroster stopped engaging, the rpms will start fluctuating from 2 suddenly up to 6-8 without warning or acceleration then go back down and back up as if it's chugging along. Even when applying the brakes, this will continue to happen and there's concern for Rear-ending or crashing when this happens. When driving home 2 nights ago the county police pulled my vehicle over due to burnt out headlight, which was replaced less than 6 months ago. Took the car in to get bulb replaced today and multiple bulbs later, the light is not fixed and it was said to be electrical and need to go to another shop. Beginning to wonder if this is all a bigger problem about to happen with engine/ powertrain.. with commute to work in the dark and electrical problem in the headlight randomly and the acceleration issues there is definitely a concern for safety.

My vehicle had 2 recalls and I took it to the local Chevy dealer where I had purchased the car in 2018. The windshield wiper problem was repaired but I was told they did not have the correct parts to repair the headlights. After 3 days I was told the car was ready and I was assured by the service manager that the car was done. However, the headlights were not repaired..

Head lights on low beam are set to the right and can not be modified or corrected by the dealer. During rainy/overcast nights it is impossible to see clearly to the front and to the left of the vehicle. At dusk, even though headlight indicator is on, it appears the headlights are off. On moonless nights, it is extremely difficult to see the road clearly. If a fix isn't provided someone will be killed.

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.
