They fixed the noise but I've had this vibration between 35 and 50 MPH during full force acceleration that is only getting worse. Tesla said they can't feel it when test driving it. The vibration is lateral from side to side with a little bit in the forward direction. But because it's mostly lateral, something is disturbing the acceleration force on just one side. Frequency is 28 HZ. Total lateral g-force acceleration is 0.8 gs. It's a pretty strong vibration. Here are some charts. The blue bulge in each is the vibration. I used the app called Accelerometer Meter in the Google Play store. Anyone care to download it and take a run from 0 to 50 MPH. If you send me the file, I'll produce the graph for comparison.
