Consumer Description

ON MAY 15TH, 2019 WITH 103,249 MILES ON MY ODOMETER, I UPGRADED MY TESLA MODEL S 70D FIRMWARE FROM VERSION 2019.12.11 TO 2019.16.1.1. ON MY NEXT CHARGE TO 80%, MY MILEAGE CAPACITY WAS DRASTICALLY REDUCED FROM 199 MILES TO 167 MILES FOR A LOSS OF OVER 30+ MILES FOR NO KNOWN REASON. I DISCUSSED THIS WITH A COWORKER WHO HAS A SIMILAR EARLY 2016 MODEL S 70D WHO EXPERIENCED THE SAME SAME LOSS OF RANGE. MY RESEARCH HAS LEAD ME TO UNDERSTAND TESLA TOOK ACTION TO DOWNGRADE HORSEPOWER AND RANGE ALONG WITH ALL OTHER ASPECTS OF PERFORMANCE THROUGH A TOTAL VOLTAGE CAP AFTER CLAIMING TO BE RELEASING A FIRE-SAFETY UPDATE, BUT OFFICIALLY NO SAFETY UPDATE WAS RELEASED. THIS CHANGE HAPPENED WHILE THE CAR WAS PARKED IN MY GARAGE AND STATIONARY.
