NHTSA Complaint #11271662 — 2013 TESLA MODEL S

RE: NHTSA ACTION NUMBER: DP19005 - INVESTIGATION SUBJECT : BATTERY MANAGEMENT SOFTWARE UPDATES AFTER MOST RECENT FIRMWARE UPDATE (EXACT DATE UNKNOWN -- SOMETIME LATE THIS SUMMER)-- SUPERCHARGING SPEED APPEARS TO HAVE BEEN LIMITED. IT NOW TAKES 2-3X THE AMOUNT OF TIME TO CHARGE WHEN TRAVELING. I TESTED MULTIPLE SUPERCHARGERS FOR MY TRIP WHICH OCCURRED ON DURING THE WEEKEND OF 9/2. I AM FULLY AWARE OF CONDITIONS THAT CAN SLOW THE SPEED (STALL SHARING, HIGH SOC, LOW/HIGH BATTERY TEMP, ETC). NONE OF THESE CONDITIONS WERE PRESENT -- YET MY CHARGE SPEED WAS LIMITED DURING ALL CHARGING SESSIONS AND ACROSS MULTIPLE LOCATIONS/DATES/TIMES DURING THIS TRIP. I'VE BROUGHT THIS CONCERN UP ON 2 SEPARATE OCCASIONS: 1. 9/5/19 - WAS TOLD "TESTED ON SUPERCHARGER AND VERIFIED VEHICLE CHARGING AT EXPECTED RATE, NO FURTHER ACTION REQUIRED" 2. 10/3/19 - VERBALLY - SPOKE TO MOBILE SERVICE TECHNICIAN WHILE PERFORMING SERVICE AT MY HOUSE. HE DID NOT CONFIRM OR DENY MY CHARGE RATE WAS LIMITED. I AM CONCERNED THAT MY BATTERY CHARGE RATE IS LIMITED DUE TO A FIRE RISK, AS THE SOFTWARE UPDATE WAS RELEASED AFTER CARS CAUGHT ON FIRE THIS YEAR.
