'Check Passenger Seat Setting' Alert
 

This just started last night. After driving back, passenger gets out and I turned the car off-just fine.

I get back in and start the car, new alert - Check Passenger Seat Setting.

Now, I changed nothing. Very odd that this happens. I start the car then I sit in the seat - error goes away.

Is it possible some of the pressure-contacts in the seat are messed up? Very odd that this happens all of a sudden.

Found out what it was...

A large water-bottle was squished under the seat. Removed it - no more warnings.
