One problem related to headlights has been reported for the 2012 GMC Terrain. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2012 GMC Terrain based on all problems reported for the 2012 Terrain.
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.
