Engine started consuming oil at around 90,000 miles. First noticed after a Oil change with the dealer we bought it from. Questioned them about it once we checked the oil, and noticed it being low after experiencing a engine noise. Dealer had us bring it back, refilled it, and test drove it for 20 miles. They sent it back with us, stating it may not have been topped off correctly. Noticed the issue several more times, and told the dealer, they then had us to a oil consumption test. After test was concluded recommended that the piston rings be replaced at a cost of $2202.02. GM first refused coverage even though this is a known issue with Terrains with the 2.4 cyl. engine. Dealer resubmitted to GM rep., Rep. admitted this is a known issue, and that GM is waiting to see if they experience enough complaints to meet the 10% of production number before it is covered 100%. Contacted GM customer complaint line with no luck in getting additional coverage, even though GM extended coverage for earlier models with this issue.
The contact owns a 2017 GMC Terrain. The contact stated while driving approximately 25 mph, the vehicle lost electrical and motive power. The contact was able to restart the vehicle. The contact stated that there was no warning light illuminated. The vehicle was diagnosed but not repaired. The manufacturer was informed of the failure. The contact was still awaiting a response. The failure mileage was approximately 48,850.
My check engine light came on along with a a message that states 'reduced engine power' and a message reading 'service stabilitrek when I was driving on the highway at 70 mph. This created suddenly jerking and slow acceleration so that I had to pull off the road. I found a forum at [xxx] that reveals that this has been an issue with GMC modes at least as long as 2011. The duration for which this has been a problem with GMC models, and the fact that stabilitrek is an integral safety feature of the vehicle in avoiding accidents seems to merit a recall.
