Steering Rack Replacement for Loud Noise from the front and Steering Wheel Vibration Only Under Autosteer Following up on the posts below from the Firmware 7.0 thread, when I took my late-Dec-2014 P85D for the LTE upgrade last week, I mentioned this to my service advisor at Tesla Burlingame and then took a technician for a ride-along this week to reproduce the issue. The service center folks hadn't heard of this issue before and opened a case with Engineering who've now recommended that the Steering Rack be replaced as that noise and steering wheel shudder shouldn't happen under Autosteer+TACC. It was so unpleasant that I was choosing not to use Autosteer if the real speeds were in that nasty band of about 25 mph to under the set TACC speed (of, 65-70 mph on the freeway). Burlingame is getting the Steering Rack from Fremont and my poor car's going in from some extensive work after the minor LTE upgrade work last week. Heads up to the posters below and others who may have experienced this.
