Consumer Description

RE: NHTSA ACTION NUMBER: DP19005 - INVESTIGATION SUBJECT : BATTERY MANAGEMENT SOFTWARE UPDATESSTARTING WITH A SOFTWARE UPDATE IN MAY 2019, TESLA REDUCED BATTERY CAPACITY FROM 73KWH TO 62KWH. THEY CLAIM THEY DID THIS "OUT OF AN ABUNDANCE OF CAUTION" AFTER SEVERAL NON-CRASH FIRES HAPPENED TO THESE MODELS. 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. THERE IS A FIRE SAFETY ISSUE HERE THAT IS NOT MADE PUBLIC BY TESLA.
