NHTSA Complaint #11615753 — 2016 CHEVROLET EQUINOX

Maintained vehicle with regular oil changes, tire rotations and inspections. Last oil change was June of 2024. Minimal driving throughout summer as both drivers are teachers and home most of the summer. Vehicle engine light illuminated on 9/12/24 with no prior issues or lights illuminating. Vehicle then went into what felt like "limp mode." Vehicle was taken to certified Chevy dealership service center. Initial diagnosis indicated there was little to no oil left in the engine. No visible leaks were seen on driveway where it has been parked, no smell of burning oil occurred prior to engine light illuminating. Oil life monitor stated 65.89% remaining. Visible leak diagnosis passed inspection. Diagnosis of misfire/engine related concerns. While on phone with mechanic it was stated that pistons and rings were malfunctioning. Upon researching issues, I discovered that there is a well known issues within GM of this exact problem existing in which around roughly 90,000 miles (my vehicle is currently at 91,000+) this specific engine starts consuming oil at a massive rate without indicating any leaks or smells of burning oil. Service center quoted between $6500-$10000 to repair. After I provided feedback about what I had discovered, I was told by mechanic that this is a well known problem with this vehicle. Extended warranties for this issue has been issued however, I am being asked to cover the cost to repair a known problem within the 2011-2017 GM engines in the Equinox and Terrain models.
