November 2022, I made a warranty claim regarding the engine. The extended warranty provider Portfolio paid $18,000 to the GMC dealer in Santa Monica to replace the engine. The dealer replaced it with a new GMC factory rebuilt engine. Since that engine was replaced, I have put approximately 32,000 miles on the vehicle, so even though the odometer reads 144,600, the actual mileage is the aforesaid approximately 32,000 miles. I have maintenance records at Firestone for past 26 months In past 4 months replaced belts, alternator, battery, one tire (other tires in good condition) Filled up freon and replaced AC condenser last spring Changed oil (synthetic) this week No carpet stains
