So my Volvo started giving me an alert that the car needed to be put in Park after the vehicle was shut off. Of course, the car is in park. After several minutes of turning on and off, shifting in and out of gear, the alert would go off. Now it started saying my driver-side door is open, all the time. So I now constantly have both alerts beeping at me. Any insight would be great! Thank you in advance.

 

A good first step would be to scan the car with a compatible scanner that can talk to all the control units. Multiple weird messages can be caused by water getting into the CEM - Do you park the car in the rain?

 

The car is usually in a garage. Not very often in moisture.
