NHTSA Complaint #11608030 — 2017 VOLVO S60

Yesterday I took my one year old granddaughter to North Carolina, which is an hour and a half drive away. We had breakfast with family members and I loaded her into the back seat. When I closed the door it looked as if the door closed, but as I began to drive, the door swung open. I attempted to close the door again, and the latch would not connect to the hook inside of the driver side rear door. I ended up needing to have my son sit in the back seat and hold the door closed the entire ride home (an hour and a half) to make sure that the door would not open again. I am currently driving my "new" car with a ratchet strap going from door to door to hold the door closed so that I can go to work. I found information stating that there was a recall on the Volvo S60 (2017) but when I enter my VIN nothing displays. I just bought the vehicle in February and the dealership is telling me that this will cost me $450 to repair on my MAX CARE warranty. Why? When the vehicle had a recall on it in 2020 that obviously was never addressed, prior to me purchasing it.
