2015 Volvo XC70 Engine Problems

My engine oil light came on recently so I took my car to the auto service center to check. The auto repair staff performed and inspection and found excessive oil consumption stemming from a defect in the pistons, piston rings and piston heads. They gave me a copy of Quality Bulletin from Volvo regarding the extended warranty P10207: VEP4 Oil Consumption Test; Model Year 2015-2016. Volvo provided an extended warranty for this defect but never informed me of the defect. Initially, Volvo said they would provide coverage for 10 years which would have covered my vehicle but Volvo decreased the period of coverage to October 2024. Now Volvo won't pay for the repairs which are estimated at $10,000. It should have been a recall, according to the auto service center. Apparently, auto companies don't like recalls due to the negative publicity. Instead the auto manufacturers provide so-called warranties for defects of automobiles for a limited time period. Had I I would have taken my car to the dealer for repair if I received such a letter from Volvo. My car is only worth $12,000 at this point since it is 10 years old but I have only 66,000 miles on my car which is low (particularly for a Volvo). I have written Beyer Volvo in Falls Church, VA, asking them to pay for the repairs, as well as Volvo North America. Both declined to provide any payment for repair of my vehicle. There are class action lawsuits against Volvo for not informing their customers of this defect. NHTSA should have issued a recall. Can NHTSA help me with this problem now? My car is not safe to drive since the oil will leak from the pistons into the rest of the engine. I can't afford to buy a car right now. It is wrong that Volvo is getting away with this defect without paying for the repairs of my cars.
