My 4 cyl. AWD GMC Terrain has had excessive oil use which caused premature failure of the timing chain, loss of power/compression, blown engine, damage to exhaust manifold, cellinoids, and melted the catalytic converter. Its was a road safety, poor emissions due to failed catalytic converter. Headlights are too bright for oncoming traffic at night. Another road & safety hazard. Auto warranty is refusing to cover parts listed above caused by the timing chain and excessive oil consumption problems.

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.

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. In all three cases, the bulbs with the female plug in and the male electrical connection has been replace. This vehicle has only 28755 miles on it. Just noticed the low beam light on right side not working again today. Replaced this side within the last 9 months.

My 2012 Terrain is getting water in the rear left tail light. I was told that it was a vented tail light and the vent was blocked by dirt and debris and they would have to replace the taillight and replace both seals. When I lift the hatchback up water drains out from the interior side of the hatch back into the vehicle. GMC of watertown Connecticut says that this is not covered under my extended warranty. I called GMC corporation and they said that this was a defect but is normal with these vehicles. GMC case number 8'3054294483. I have the better business bureau auto line investigating the problem and that case number is pgm1719802. GMC told me the water in the tail light can short out my electrical systems and this defect has been by known GMC from 2011. Since I purchased this car new in 2013 I have had multiple problems such as having the back camera replaced twice, front navigation screen going black, stabilizer malfunction which was also a problem with this vehicle when it came off the assembly line, having the computer updated every year because they say of all the computer chip modules that are installed in this vehicle, just to name a few which are all documented with GMC. I am submitting this to make the federal government aware that this defect is potentially a hazard to the electrical system and has been known to GMC for a long time and they have not corrected the situation. Their solution is replacing the tail light at a cost of $254 without tax. I believe this is a serious defect and if you require more information I will comply to any requests that you have. Also all conversations with GMC corporation and BBB auto line were recorded if needed. Thank you for your time.

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.
