    I just spent 1,600 dollars to replace the timing chain. I know their were recalls on this, I was wondering why my vin and model were not included in these recalls?

    Once again, timing chain incident, this time while driving, wasn't expecting it, suddenly my Terrain steering when became stiff to turn, and happened to realize the car motor had shut off and rolling to the right, nearly hitting parked car. I tried to start vehicle, but made a whining sound, but did not start, yet check engine light was on. I had my OBD reader handy, and got p0011, p0017 codes, which tell me it was the timing chain again in this car. This very dangerous because we could of collided with a parked vehicle, if not for me struggling so hard to steer vehicle while steering wheel was stiff.

    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.

    All of these models have been prone to oil consumption issues, during the pandemic GMC of Southern pines North Carolina decided to charge us $500 for the repair because we were not able to make it on time. This is something that GMC has been avoiding and throwing its customers in a loop in order to fix. Oil consumption due to the fault of GMC can be found in our records of repair.

    Just recently I took my GMC Terrain on a recall . They told me that the timing chain had to be replaced. The car only has 111,441 miles, I don't think at 111 thousand miles a timing chain should be replaced. It must be a manufacture defect . We dealing with a chain, not a timing belt.
