Blind Spot Detection problems of the 2019 Ford Fusion

Sometimes when I get in the car and put my seat belt on I can be driving and it unclip tey to put it back in and it want go have to play around with it before im able to clip it into the other part for safety. My safety is put at risk cause when im driving the seatbelt un hooks. No cant afford to take it because it cost almost 200. 00 to diagnose any problem with the car. No warning light or anything also sometimes my car say my blind spot camera are not working and it will pop up on my dash. My back up camera instead of it showing whats in back of me it sometimes show whats in front of me.

I have took it in to get it repaired about a year ago the sensor went off and got them fix but when I explain what else was happening they found nothing months down I has other people and couldn’t find the problem with my vehicle which is now a risk to drive the steering wheels gets stiff and hard to turn I have to wait for the system to kick back originally I was told it was a O2 sensor.
