While going very slowly up a driveway or over a speedbump - w/ the back wheel's not going over at the same time - I'm hearing a very loud creaking sound in back (sound seems to come from inside behind the drivers seat). It's not the rattle from the back stabilizer plastics. Sounds like suspension for certain.

This plus the steering wheel vibration and the tire pressure sensors being way off (w/ no dealer fix) has me feeling down about the car. :-(

 

If one or more of the wheels have been off the car for any reason, the dealer need to reset the sensors.
I had my wheels chromed and that situation showed up, but
the dealer took care of it esasily.
