NHTSA Complaint #11306594 — 2013 TESLA MODEL S

IN THE PAST YEAR, MY CAR HAS LOST A SIGNIFICANT AMOUNT OF RANGE, AND HAS EXPERIENCED SLOWER CHARGING SPEEDS. AFTER CALLING THIS TO THE ATTENTION OF A TESLA SERVICE CENTER, I WAS TOLD THAT THERE WAS NOTHING WRONG WITH MY BATTERY AND THAT THE REPORTS OF A SOFTWARE UPDATE THAT LOWERED RANGE WERE RUMORS. I EXPERIENCED A 6% DECREASE IN RANGE IN A FEW MONTHS. MY CAR WAS 6 YEARS OLD AND ONLY AND 9% BATTERY DEGREDATION OVER THAT PERIOD. IN THE PAST 6 MONTHS IT HAS LOST AN ADDITIONAL 6% RANGE NOW TOTALING 15%, AND THAT ADDITIONAL RANGE REDUCTION SEEMS TO BE LINKED TO A SOFTWARE UPDATE FROM TESLA. IF THERE IS A PROBLEM WITH THE BATTERY THAT MAY CAUSE A FIRE, AND THAT IS THE REASON THAT TESLA DID INDEED ROLL OUT A SOFTWARE UPDATE TO INCREASE SAFETY, TESLA SHOULD REPLACE THE BATTERIES INSTEAD OF REDUCING THE RAGE . THE MOST SAFE THING TO DO IS REPLACE THE BATTERIES. I LOVE MY CAR, AND I AM A BIG FAN OF TESLA. TESLA IS VERY PROUD OF SAFETY IN THEIR CARS, SO THEY SHOULD DO THE RIGHT THING AND REPLACE THESE BATTERIES.
