2021 CHEVROLET SPARK Power Train Problems

I lease a car through Carvana, and they informed me that the car was safe and properly inspected. In the first 2 weeks, I took the Chevrolet to a certified dealership for a routine inspection. I was informed that the vehicle has severe mechanical and electrical issues. The engine needs to be replaced entirely because they found shredded metal pieces in the engine oil. The car also requires an entirely new steering and alignment system. It also needs a new heating system. The total cost is 7700, which is close to the current value of the car. I have informed the caravan and Silver Rock third-party insurance. They failed to inspect the vehicle and follow DOT safety requirements. This car should not be available for purchase. This car requires several weeks of repair, which puts me at risk of driving. I could have easily ended up in a deadly accident...
