often when getting into or out of parking spaces, you have to turn the wheel all the way to the right or left to make a tight turn. in those instances, the steering wheel reaches the end of its turning and starts clicking as if to say, "i don't like this!" "you've turned me too far!" as you are rolling with the wheel in that position, it continues to click like it's broken or something. in our other cars this hasn't happened. you just reach the end of how far it will turn and keep backing out and it's quiet. our 2014 S60 did this very loudly, and you could even hear the clicking from the outside of the car. i had an appointment to get it looked at but then we ended up getting another Model S. our new 2016 P90D has a quieter clicking, but it's still a little unnerving to hear it and passengers always wonder why does it do that? does anyone else experience this?
