Engine Oil Leaking problems of the 2014 Chevrolet Malibu

On 7/5/20 the vehicle was in motion going down the highway and the high pressure fuel pump mounted on the engine broke lose, dropped into the engine and tore apart the engine. Was towed and fixed by closest gm dealership (deery brothers, west burlington, IA). There is a recall for a bad weld on the high pressure fuel pump for 2016-2018 Malibu's resulting in the exact issue I had on my 2014. The dealership said gm, Chevrolet and the dealership (which is a gm certified dealership where I bought the car certified pre-owned in 2018) said they all bared no responsibility for the issue. I paid $3,128 for the repair on 7/17/20. Two days after bringing my car home, there is an oil leak that was never there before. The dealership says this is a hole in the oil pan, and again is my responsibility to pay for in full to be fixed. I received a letter from Chevrolet on 7/16/20 saying there is a recall for my VIN # for an oil pressure valve. Incorrect oil pressure could have caused the high pressure fuel pump to explode causing the issue on 7/9/20. I do not believe that between the two recalls issued by Chevrolet for my car model I should be responsible for the full weight of the repairs on a car that was purchased certified pre-owned with a warranty two years prior, not to mention I've had all regular services done in a timely matter at the same dealership, that has under 90,000 miles and is only six years old. There is no reason for such extensive engine damage to such a new car with no previous issues.

We purchased this vehicle as for safety and convenience, we are student and full time workers. We share one care and because of that we took care of the car like recommended. Since October, we have been isolated, depended on uber and lyft because of gm not having the part for the vehicle. We searched everywhere, we called gm and filed a complaint, nothing was done. We paid to get the diagnosis done and said we need the oil control valve and part number 12633613. No one has it and everyone is looking for the same part. There is an issue there and gm should be held responsible. We're still paying for the vehicle. The incident had while the vehicle was in motion, as I was driving to work, I heard a loud pop and lucky I was to my job 21880 state road 7, boca raton FL 33064. I parked the vehicle and went out to check, oil leaked everywhere leaving a trail behind. Called my insurance for road side assistance. We were able to purchase the off market brand which didn't last even a month! now we stuck. Thank you chevy,.
