I was driving from San Jose to Santa Cruz on highway 17. If you've done this drive you know how 'interesting' it can be..fun in a Tesla.
Coming downhill at high speed in the traffic flow I was under full regen ..the usual concrete barrier off to my left and car to the right....the left front tire 'shuddered' ...no skidding but was fighting me. The traction control icon came on for a brief moment.
I held course and didn't hit the wall or the car to my right. In few minutes it happened again, in the same conditions.
Pavement dry as bone, no oil, no sand. Autopilot (AP1) NOT in use. (I'm not that crazy)
What was this? Did the side ultrasound sensors do this? (Perhaps a car too close to the right?)
I remembered the time for later and also did a 'bug report...traction control'. Should I just ignore this or should i make an appointment to have it checked out?
