I have a 2018 Model S 100D. For about 1-2 weeks I am getting this strange periodic vibration/shaking of the car above 65-70 mph. At constant speed, 75 mph for example, every 100 seconds I get this vibration/shaking of the whole car (NOT the steering wheel). It feels like in a massage chair. That vibration is about 6-10 Hz.
It comes and goes regularly. I feel it get strong and then lessens with a period of 100 seconds. For 50 seconds I feel nothing, then it comes on, gets stronger, and then weaker. I feel it for 50 seconds then. Every 100 seconds, like clockwork at constant speed.
At 75-80 mph the vibration is stronger and faster, about same 100 second period...hard to tell
I balanced all 4 wheels, but no effect.
As anyone ever had this issue? If yes, what was the problem and fix?
