Automatic Transmission Cooler problems of the 2018 Ford Fusion

I purchased the car January 17, 2024, few weeks later the check engine light came on then disappeared, I was also experiencing problems with the seat cooling function, as the touch screen controls was showing that they were both on and it was still winter/rainy season outside. I took the car innto Ford dealer at sanbernardino CA, they told me that most likely it was just a dashboard light malfunction because the diagnostics results came out fine and after researching in other manuals even though the seat cooling function was switched to "on", the car did not come equipped with seat cooling only heated seats. 3 weeks later after taking my car home, the check engine light came on again on y dashboard, I bought an obdii diagnostic tool, the result came back with 2 different powertrain codes that were strictly manufacturer codes. 1st code was p1450 which is defined as unable to bleed gas tank - excessive vaccum. 2nd code was p2196 which is defined by O2 sensor stuck trying to correct 1st code. The p2196 eventually cleared on its own but the p1450 became permanent. I had a diagnostic mechanic take a look at it and he told me the same thing, except that the main culprit is the purge flow valve, which is a recall issue on other Ford Fusions. When I purchased the car, I was showed that the car had no recalls but the "myford" app and ownership didnt transfer to me right away until 30 days after the purchase, which is when it finally let me viewed the cars prior service / maintanance history and even though the car sales lady showed me VIN records where it says there is no recalls and it had no accidents, records that she showed me 30 days prior to me gaining actual ownership thru "my Ford" when purchasing the vehicle. The "my Ford" app states that it seems as if the car was in an accident in the past because almost $8000 went into repairs towards transmission and other main components. California smog check records show that the car has only had 1 test in CA last sept 2023.
