Assist problems of the 2020 Subaru Ascent

I was driving and I got check engine light and all safety features disabled while I was in the freeway, luckily I was able to drive to nearby Subaru dealer for inspection and I found out that there was a recall on the engine for this vehicle and when I contacted the manufacturer they asked me to take it for diagnostics and I did that at a Subaru retailer, but the case manager told me that this recall is being completed for the previous owner of the vehicle and cannot help me with anything, which was never disclosed when I was buying the vehicle.

My vehicle is fairly new 7 months to be exact. When it was 4 months old I've started to notice rust and corrosion on the window panels that are metal. When I went in for oil change service they deny that there is rust and just offered to polish it. At 7 months the windshield has chips and cracks which is odd without a reason.

I have had my lane assist come on by its self a few times, which is very dangerous because it seems to take over and will pull on the steering wheel. I’ve also brought my car back to the dealership a handful of times to have it hooked up to a computer and also someone ride with me because the car will either hesitate to accelerate or stutters and doesn’t seem to want to go when I am between 20-30 miles an hour. Other times when I’m at a light or stop sign it hesitates also. I was told there was nothing wrong with it and they reprogrammed to transmission but it didn’t help at all.
