In owners' own words
I purchased a 2011 terrain not knowing there was an issue with the excessive oil consumption. I have called GMC for a fix and have been told that nhsa is the one who decides what VIN # get a letter to get the motor fixed.
I was traveling down the road with my family in the vehicle when all of a sudden the vehicle decelerated and starting vibrating and operating roughly.
Odb code P0014/P0017 is a GMC recall and I would very much like to bring it and let you guys fix it because it is becoming a problem!

Recalls for the 2011 GMC Terrain: 4
A reflection caused by the headlight housings may illuminate areas above the vehicle and outside of the driver's view with excessively bright light. The bright reflection may cause a glare for other drivers, reducing their visibility and increasing the risk of a crash.
Also, certain 2013 Buick Encore, 2011 Buick Regal, 2013-2014 Buick Verano, 2011-2016 Chevrolet Cruze, 2010-2013 Chevrolet Equinox 2013-2015 Chevrolet Malibu, and 2011-2013 GMC Terrain vehicles may have been serviced with similar defective replacement electronic park lock levers. If the key is removed without the transmission in PARK, the vehicle may rollaway as occupants are exiting, increasing the risk of injury.
In the affected vehicles, the bolt that secures the driver's and passenger's power front seat height adjuster may fall out causing the seat to drop suddenly to the lowest vertical position. If the driver's seat unexpectedly drops, the distraction and altered seat position may affect the drivers' control of the vehicle, increasing the risk of a crash.
The driver and /or front passenger safety belt buckle anchor may fracture and separate near the seat attachment in a vehicle crash. The safety belt system may not restrain the occupant(S) as designed and could increase the risk of injury.
A recall may cover only some cars of a model year; the campaign size counts every model and year it lists. Enter your VIN at nhtsa.gov/recalls: dealers fix open recalls free.
