“The headlight system on this vehicle leaves a lot to be desired. The headlights are veiled somehow so that there is no illumination above the headlights with low beam. When driving in hilly areas, the forward projection of the headlights is very limited when traveling down hill. The hi beams illuminate well, but when driving in the country with oncoming traffic and low beams in hilly areas, the view of the side of the road ahead is very restricted. If I had driven this vehicle at night before I bought it, I doubt that I would have bought it, it's that bad.”
NHTSA complaint #10482948, filed 2012-11, 100 miles“The low beam h11 bulb is causing the (male/female plug in) for this component to overheat causing the plastic to become charred, partially melted and brittle in which the low beam light stops working due to this problem. The wiring is becoming soft at the plug in connection from this heat and allowing the protective wire insulation to be melted permitting the bare wire to be visible which could produce a fire hazard at this location. This has occurred on the right side twice and on the left side once. …”
NHTSA complaint #11043757, filed 2017-11, 28,755 miles“I have a problem with the Headlights they are yellow and there is no way I have found to clean them. It makes it hard to get a bright view at night especially when travelling on secondary streets with low or limited lightning. I have also noticed that a lot GMC Terrains have the same issue. Is there are will there be a recall on my 2012 GMC Terrain it does create a very dangerous situation especially at night. I no longer like to drive at night because of this problem, the coatings on the lights makes the night vision awful. Thank you for reading. You can send me a reply.”
