general problems of the 2015 Buick Encore

My check engine light came on so I took it to a repair shop. They put it on their diagnostic system check computer and the code #po299 came up. After further inspection and investigation, the failed part is the turbocharger- a1140104n. This vehicle's, VIN number, model year and mileage qualifies it for warranty replacement and labor for the faulty part. However, because it is a Buick and not a chevy the dealership is not authorizing the repair, even though it is the exact same system and part that is being replaced in the chevy models. Without this part functioning properly, it affects performance and the car's ability to accelerate when needed which makes it a hazard to drive if you should need to accelerate quickly.

It’s it’s firing and shaking, and I have kept up on the oil changes. It’s a lot of money.

After driving the Encore for 30 minutes then making stops at different places a few minutes apart, when the car is started there is a smell of gas inside the car. Does not happen when starting the Encore for the first time of the day. I was inside the store from 5 minutes to 30 minutes, has happened several days now.

Code po300 ignition coil arcing to the valve cover random cylinder misfire.

I purchased this vehicle in 2017 with only 45,000 miles, 1 year warranty was purchased. I have had constant issues with tires, but more seriously I have had over $2000 in repairs for intake manifold, air conditioning, various issues with tires, repaired thermostat. I had an ignition problem repaired in 2019 and now the check engine light keeps flashing, the motor doesn't want to engage and I am in fear for my life that I will be on the highway and it will just shut down, causing a collision!.
