My 2015 GMS Terrain SLE-2 engine failed last week with 109,000 miles, just past the warranty of course. I was told the engine ran out of oil yet there were no signs of leaks that the service department could find, nor any signs in my driveway. This caused the timing chain to fail and lifters broke. I have oil changed regularly at my local dealership and have all receipts. Come to find out there is no low oil pressure light installed in this model. I was told by the service department to replace the engine for $9900. The alternative was to scrap the car.

Current Blue Book value is $11,873 so replacing the engine was not worth the money. The dealership had NO explanation as to how it ran out of oil. So I purchased another car and scrapped the Terrain today. Now, after some investigating I have learned that I could have spoken further with the dealer and they would have helped IF I still had the car. Seems as though GM knows about this issue yet I was never informed. Thankfully it died in my driveway and not during commuting hours on the highway going 70 mph! I did file a safety complaint with the NHTSA.

I got my Fiancee a 2015 GMC Terrain back in February 2017, and in January of 2018 the engine failed and we had it towed back to the dealership to see what the problem was to see if the extended warranty will cover it. The dealership took a look at it and the inspector from the warranty company came. The engine was consuming the oil which caused the engine failure. They weren't going to cover the damage so we had it towed to an auto body shop and had to get an Engine from another GMC Terrain for $2700.

Now today on November 11th, 2019, not even a year since we got a Replacement Engine for our GMC terrain, my fiancee called me stating her GMC Terrain made a knocking sound then died, so we had the vehicle towed back to the same auto body shop who we bought the engine from. As of 6:00pm on 11/12/19, the auto Body shop told us that engine also consumed all the oil and once again the engine failed, and she still had 1500 miles left for another oil change.

This is the 2nd Engine from a GMC Terrain that consumed all the oil, and then the engine failed within less than a year. I know there is a class action lawsuit regard 2010, 2011, 2012, 2013, 2016 GMC Terrains, and honestly I think it should be all GMC Terrains from what the Body Shop told us. He has been seeing these on all GMCs about oil consumption and engine failures - and now we have to spend another 2700 in less then a year. There should be a recall or lawsuit on all GMC Terrains.
