NHTSA Complaint #11510817 — 2017 CHEVROLET EQUINOX

My 2017 equinox which I purchased at this dealership starting burning excessive oil and has bad piston rings, they quoted me a $9500 for engine... I had those issues at 97500 miles and the dealership failed to properly inspect and fix the rings even though this motor was known for these issues. The failed piston rings should have been fixed when my vehicle was covered under warranty at approx 97,500 miles! My equinox has approx 100,600 miles on it currently and has sat for 1.5 months. So 600 miles past the warranty and now it needs a new engine? It needs a new engine because the service department knowingly failed to thoroughly fix my car when I had it in at 97,500 miles.
