Consumer Description

IN MID MAY, 2019, TESLA SENT ME A MANDATORY SOFTWARE UPDATE FOR MY 2015 TESLA MODEL S P85D LUDICROUS WITH THE 85 KILOWATT-HOUR BATTERY. IMMEDIATELY FOLLOWING THIS SOFTWARE UPDATE MY TESLA EXPERIENCED A 30% DROP IN SUPERCHARGING RATES AT ALL STATES OF BATTERY CHARGE LEVEL AND BATTERY INITIAL TEMPERATURE. I ALSO EXPERIENCED A 25 MILE DROP IN MAXIMUM RANGE WHEN BATTERY IS AT 100% CAPACITY. I HAVE BROUGHT MY VEHICLE STILL UNDER FULL WARRANTY TO TESLA SERVICE CENTERS IN DUBLIN, CA AND BERKELEY, CA. THEY HAVE BEEN UNWILLING TO BRING CHARGING RATES AND BATTERY RANGE CAPACITY TO ORIGINAL LEVELS BEFORE THE MAY, 2019 SOFTWARE UPDATE, OR TO EVEN ACKNOWLEDGE THAT THERE IS AN ISSUE. THEY HAVE REMOVED CAR PERFORMANCE FOR WHICH I PAID A CONSIDERABLE AMOUNT OF MONEY WITH NO COMPENSATION OR ANY KIND OF EXPLANATION.
