What 459 owners told NHTSA about the 2013 Tesla Model S Bev

TESLA RELEASED AN UPDATE THAT THROTTLED HOW FAST MY CAR DC CHARGES AND REDUCED MY RANGE. I USED TO BE ABLE TO START DC CHARGING AT 99KW AND NOW IT STARTS AT 72KW AND TAPER FROM THERE. ALSO I CAN'T CHARGE TO 100% NOW. IT STOPS AROUND 97% AND SAY "CALCULATING REMAINING TIME" AND AFTER 30-40 MINUTES STOPS AND SAYS CHARGING COMPLETE. MY MAXIMUM RATED RANGE IS NOW 167 MILES DOWN FROM 208 MILES. THAT'S A 20%, 40 MILE LOSS OF RANGE. I HAD TESLA LOOK AT IT TWICE AND THEY SAY NOTHING IS WRONG. LAST APPT THEY SENT ME A TEXT ON FEB 10TH AND CANCELLED MY APPT SAYING THERE'S NO ISSUE. NOW IN THE WINTER I CAN'T MAKE IT HOME TO TOLEDO OH FROM COLUMBUS OH A 132 MILE TRIP. REAL WORLD IN THE COLD YOU LOSE 25% RANGE TO KEEPING THE BATTERY WARM. WITH TESLA CAPPING MY RANGE WITH THE UPDATE PLUS THE RANGE LOSS IN WINTER I'M SHORT 10 MILES.

RE: NHTSA ACTION NUMBER: DP19005 - INVESTIGATION SUBJECT : BATTERY MANAGEMENT SOFTWARE UPDATES 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 EVER. AFTER INSTALLING A SOFTWARE UPDATE 2019.16.X I LOST RANGE AND THE ABILITY TO CHARGE THE BATTERY AT HIGHER RATES. BEFORE THE UPDATE, I WAS CHARGING AT 100% TO 255 MILES ON MY 85KW BATTERY PACK. THE ORIGINAL MILES WERE 265 MILES WHEN THE CAR WAS NEW. OF COURSE NORMAL DEGRADATION IS EXPECTED. I CURRENTLY ONLY GET 239 MILES ON A FULL CHARGE AS APPOSE TO 255 MILES.

TL* THE CONTACT OWNS A 2013 TESLA MODEL S. THE CONTACT STATED THAT WHILE ATTEMPTING TO PARK AT APPROXIMATELY 2 MPH, THE VEHICLE SPONTANEOUSLY ACCELERATED WITH THE FOOT ON THE BRAKE PEDAL. THE CONTACT STRUCK THE VEHICLE IN FRONT. THE FRONT PASSENGER SIDE OF THE VEHICLE WAS DAMAGED. THE POLICE WAS NOT PRESENT. NO INJURIES WERE REPORTED. THE VEHICLE WAS TOWED TO THE (TESLA, 6692 AUTO CENTER DR, BUENA PARK, CA 90621), WHERE IT WAS DETERMINED THAT IT WAS VEHICLE OPERATOR ERROR. THE CONTACT WAS INFORMED THAT IT MAY TAKE APPROXIMATELY A WEEK TO GET THE RESULTS FROM THE EVENT DATA RECORDER. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 30,000.

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.

I PURCHASED A CERTIFIED PRE-OWNED TESLA MODEL S P85+ WITH 100,000 MILES OR 2 YEARS CPO (WHICHEVER COMES FIRST) AND MANUFACTURING WARRANTY UNLIMITED MILES OR 8 YEARS MOTOR AND BATTERY WARRANTY. (THIS WAS THE NOTE WHEN I PLACED ORDER -- USED CARS WHICH RECEIVE THE REMAINING BATTERY AND DRIVE WARRANTY AND A TWO YEAR, 100,000 MILES MAXIMUM ODOMETER PRE-OWNED LIMITED WARRANTY) UNTIL TODAY I WAS NEVER GIVEN MY WARRANTY DOCUMENTS BY TESLA, STILL WAITING... THE CAR CONTINUES TO SLOW CHARGE AND LOST 50 MILES WITHIN A YEAR OF THE PURCHASE HOWEVER DEGRADATION ON BOTH ISSUES WAS DONE WITHIN 4 MONTHS OF THE PURCHASE BY MANIPULATING THE SOFTWARE WITHOUT MY KNOWLEDGE/CONSENT. MY CAR CHARGED SUPER FAST BEFORE AT THE SUPERCHARGER (BEFORE - FROM 10 MILES TO 250 WITHIN 50 MINUTES OR FROM 11 MILES TO 180 WITHIN 25 MINUTES )UNTIL TESLA MADE CHANGES TO THE CAR SOFTWARE, - BUT NOW IT TAKES ME 4+ HOURS TO GET FROM 11 MILES TO 205. THE CAR WON'T EVEN CHARGE HIGHER THAN 205 ANYMORE AND WHEN I PURCHASED THE CAR TESLA ADVERTISED 265 MILES EPA. I AM TOLD TESLA SERVICE CENTER WILL NOT GIVE ME THE DIAGNOSTICS REPORT ON MY CAR, I WILL HAVE TO REQUEST IT FROM "NCDS" OR GET A LAWYER... LAST I CHECKED I PAID FOR THE CAR AND I HOLD THE RIGHT TO KNOW WHAT DIAGNOSTICS ARE THEY RUNNING ON MY CAR. THIS IS FROM 1/27/2020 12:30 - 16:43, CHANGING AT THE I-45 NW FREEWAY SC SUPERCHARGER. -STARTED CHARGING AT 11 MILES -FINISHED AT 205 MILES (NOT 100%, STOPPED BEFORE) EPA 265 - CURRENTLY 54,299 MILES. -UNDER WARRANTY (CPO & MANUFACTURING) CAN'T STAY AT THE SUPERCHARGING WITH A YEAR OLD AND A 3 YEARS OLD TODDLER (CRYING, SCREAMING, TANTRUMS, THE LIST GOES ON.. ON A CITY TO CITY TRIP AND NOT INCLUDING NATIONWIDE ROAD TRIPS ) TO GET AT LEAST 200 MILES 4 HOURS. WE CAN'T EVEN TAKE ROAD TRIPS IN TESLA ANYMORE, HAVE TO BORROW A VEHICLE FROM PARENTS OR A FAMILY MEMBER TO KEEP THE COST DOWN (HUMILIATING)

ON NOVEMBER 1, 2019, I WAS SLOWLY BRAKING AND START TURNING RIGHT INTO MY DRIVEWAY ON THE 2013 TESLA MODEL S. I FELT A SURGE OF THE VEHICLE AND 1 SECOND LATER, THE VEHICLE LANDED ON TOP OF THE STAIRCASE OF MY HOUSE ENTRANCE AND DRIVEWAY. I DID NOT PRESS ON THE ACCELERATOR AT ALL WHEN I SLOWLY TURNING INTO THE DRIVEWAY.THE VEHICLE SPED ON ITS OWN FOR ONLY A SPLIT SECOND. I CALLED TESLA ROADSIDE ASSISTANCE. THE REPRESENTATIVE CONTACTED ME AND DIRECT ME TO A REPAIR SHOP AND HE TOLD ME THAT HE WOULD HAVE THE VEHICLE'S INFORMATION TO BE SENT TO THE ENGINEERS TO FIND OUT WHAT HAPPENED. I HAD MY VEHICLE TOWED BUT TO REPAIR SHOP BUT TESLA SUPPORT TEAM HAS BEEN IGNORING ALL MY CALLS AND EMAIL. MY VEHICLE WAS CONSIDERED TO BE TOTAL LOSS BY MY INSURANCE COMPANY.

DURING NORMAL HIGHWAY DRIVING THE MOTOR MOUNT TABS ATTACHING THE ELECTRIC MOTOR OF MY 2013 TESLA MODEL S SHEERED OFF CAUSING THE MOTOR TO SLAM AGAINST THE SUBFRAME. THE VEHICLE HAS UNDER 75,000MI ON IT NOW. TESLA IS CALLING THIS A WEAR AND TEAR ISSUE. A SUBFRAME SHOULD NOT BE FAILING FROM NORMAL WEAR AND TEAR AT UNDER 75,000MI.

NHTSA ACTION NUMBER: DP19005 - INVESTIGATION SUBJECT : BATTERY MANAGEMENT SOFTWARE UPDATES. VIA SOFTWARE UPDATES, TESLA, SUDDENLY, INEXPLICABLY, REDUCED MAXIMUM VOLTAGE OF THE MAIN BATTERY. THE ACTION RESULTED IN INSTANT LOSS OF DISTANCE MILEAGE OF THE CAR OF 12 PERCENT, FROM 237 MILES TO 208 MILES. HORSEPOWER AND GENERAL PERFORMANCE OF THE CAR WAS ALSO REDUCED. TESLA HAS IMPLIED THAT THIS ACTION WAS TAKEN, FOR SELECTED TESLA CARS, OUT OF AN ABUNDANCE OF CAUTION AS A FIRE-SAFETY UPDATE, BUT OFFICIALLY NO SAFETY RECALLS RELATED TO THIS UNEXPLAINED ACTION HAVE BEEN ANNOUNCED. NO ONE ASSOCIATED WITH TESLA HAS OFFERED ANY FURTHER DETAILED EXPLANATION FOR THIS SUDDEN ACTION, WHICH, IN ADDITION TO REDUCING PERFORMANCE AND DISTANCE MILEAGE OF THE CAR, HAS ALSO REDUCED, OVERNIGHT, ITS INTRINSIC ASSET VALUE. THE RESULTS DESCRIBED HERE HAPPENED OVERNIGHT, WHILE THE CAR WAS AT REST---PARKED INSIDE A GARAGE.

TESLA MODEL S DOOR POPS OPEN WHEN YOU SELECT THE DOORS TO UNLOCK. MANY TIMES, IT DOESNT EVEN SHOW ON THE DASH BOARD, SO YOU DONT KNOW ITS OPEN UNLESS YOU NOTICE IT OR HEAR NOISE COMING FROM OUTSIDE. YOU GO CHECK AND THATS WHEN YOU REALIZE IT IS OPEN. VERY UNSAFE. SOMEONE CAN JUST ROLL OUT OF THE CAR.

TIRE PRESSURE MONITORING SYSTEM FAULT LIGHT AND LOW TIRE PRESSURE LIGHT ON. TESLA SAYS THE BAOLONG SYSTEM INSTALLED IS FAULTY AND FAILING, AND A CONTINENTAL RETROFIT MODULE IS NEEDED. MANY PEOPLE HAVE REPORTED THIS ISSUE. TESLA CHARGES OVER $700 FOR THIS FIX. IF SO MANY PEOPLE ARE HAVING ISSUES WITH THIS, WHY NOT RECALL IT?! TESLA SAYS THERES NO WAY TO RESET THE SENSOR. ONLY OPTION IS TO REPLACE IT.

ON TUESDAY, DECEMBER 10, MY WIFE WAS SLOWLY APPROACHING OUR GARAGE DOOR WAITING FOR THE GARAGE DOOR TO OPEN WHEN THE CAR SUDDENLY LURCHED FORWARD SPEED SUCH THAT THE CAR WENT THROUGH THE GARAGE DOOR DESTROYING TWO GARAGE DOORS, THE LOAD BEARING COLUMN BETWEEN THE TWO DOORS. A LOLLY COLUMN INSIDE THE GARAGE WAS BROKEN IN TWO PIECES AND OUR OTHER CAR IN THE GARAGE WAS DAMAGED AS WERE OTHER ITEMS IN THE GARAGE. THE CAR EVENTUALLY STOPPED WHEN IT HIT THE CONCRETE WALL OF THE GARAGE BUT TWO MARKS ON THE GARAGE FLOOR INDICATE THE REAR DRIVE WHEELS CONTINUED TO SPIN EVEN AFTER HITTING THE CONCRETE WALL. WE ARE THE ORIGINAL OWNERS OF THIS CAR AND HAVE DRIVEN IT FOR 6 1/2 YEARS SO WE ARE VERY FAMILIAR WITH THE CAR. THANKFULLY, SHE WAS NOT INJURED.

DUE TO A FIRMWARE UPGRADE THAT WAS PERFORMED BY THE DEALER WHEN REPLACING MY MCU, MY TOTAL BATTERY RANGE WAS REDUCED FROM 249 MILES TO 213 MILES INITIALLY. THROUGH FURTHER UPDATES THE RANGE INCREASED TO 220 MILES AND THIS IS AN ACKNOWLEDGED ISSUE BY TESLA THAT SHOULD BE ADDRESSED BY BATTERY REPLACEMENT WITH A BATTERY THAT HAS AT LEAST THE ACTUAL RANGE I HAD BEFORE THE UPDATE (~250 MILES) OR BETTER. IF THE MODEL S 85 BATTERY IS A FIRE RISK AT THE RANGE CUSTOMERS WERE QUOTED, THIS SHOULD BE A RECALL BECAUSE THROUGH PURCHASE OF A VEHICLE, THE RANGE AND SAFETY OF THE VEHICLE SHOULD BE GUARANTEED SIMULTANEOUSLY AND NOT THROUGH A FIRMWARE UPGRADE I DIDN'T EVEN REQUEST.

THE BATTERY FOR THE 2013 MODEL S 60KWH 2013 IS NOT CHARGING ANYWHERE NEAR THE CAPACITY. CHARGING THE BATTERY TAKES HOURS TO GET TO NEAR 65% OF WHAT USE TO BE FULL CHARGE AND IS NOW CONSIDERED A 100% CHARGE. THIS IS UNDER WARRANTY AND NEEDS TO BE REPLACED ASAP. THIS HAS SEVERE IMPACT TO DAILY COMMUTE AND ABILITY TO UTILIZE THE CAR. MY UNDERSTANDING IS STARTING WITH A SOFTWARE UPDATE IN MAY 2019, TESLA CAPPED THE MAX VOLTAGE THE HIGH VOLTAGE BATTERY WOULD CHARGE TO. 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.

SUMMARY: VEHICLE TPMS HAS BEEN DISABLED DUE TO A SOFTWARE REVISION. TESLA RELEASED V10 SOFTWARE FOR MODEL S VEHICLES. 2012-2014 CARS HAVE A LEGACY TPMS SYSTEM WHICH THE PREVIOUS SOFTWARE ALLOWED THE USER TO RESET THE TPMS, IF AN ERROR OCCURRED OR A DIFFERENT WHEEL/TIRE COMBINATION WAS SWAPPED FOR THE SEASON. ONCE THE RESET BUTTON WAS PRESSED THE SYSTEM WOULD LEARN THE NEW SENSORS AND THE ERROR WOULD RESET. THE FUNCTIONALITY OF THE RESET BUTTON HAS BEEN REMOVED TO ACCOMODATE NEWER CARS WITH A NEWER, SMARTER TPMS SYSTEM FROM CONTINENTAL. THIS NEW SYSTEM SIMPLY REQUIRES YOU TO START DRIVING, AND IT AUTO LEARNS THE NEW SENSORS. VERSION 10 FAILS TO ADDRESS THE NEEDS OF THE OLDER CARS WITH THE OLDER TPMS SYSTEM. AS IT STANDS NOW, THERE IS NO WAY FOR THE USER TO RESET THE TPMS, THUS OWNERS ARE DRIVING AROUND WITH A DISABLED, FEDERALLY MANDATED SAFETY SYSTEM. TESLA HAS ENCOURAGED OWNERS TO UPGRADE OLDER CARS TO THE NEWER SYSTEM AT SIGNIFICANT EXPENSE, WHEN ALL WE NEED IS THE ORIGINAL FUNCTIONALITY OF THE RESET BUTTON THAT WAS PART OF THE VEHICLES ORIGINAL CONFIGURATION.

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.

RE: NHTSA ACTION NUMBER: DP19005 - INVESTIGATION SUBJECT : BATTERY MANAGEMENT SOFTWARE UPDATES I AM AN EARLY MODEL TESLA OWNER. I STOPPED ACCEPTING OTA UPDATES TO MY CAR BECAUSE I DID NOT LIKE THE NEW FEATURES BEING ROLLED OUT. I HAVE FOUND A NEW STORY ONLINE ON TESLA THAT THEY RELEASED AN OTA UPDATE OUT OF AN ABUNDANCE OF CAUTION AFTER FIRES IN EARLY TESLA MODELS BUT THEY DO NOT GO INTO ANY SPECIFICS. AFTER READING FORUMS FOR OTHER OWNERS I SEE THAT THERE IS SOMETHING GOING ON WITH OUR CARS THAT TESLA REFUSES TO COMMUNICATE WITH US. ARE WE SAFE OR NOT WITHOUT THE UPDATE? ALSO OTA UPDATES ARE NOT MANDATORY SO IF THEY DID DO A SOFTWARE UPDATE FOR SAFETY THERE ARE PROBABLY MANY OTHERS LIKE MYSELF THAT DO NOT HAVE THE LATEST SOFTWARE UPDATE AND ARE NO LONGER SAFE. I AM AFRAID THAT MY VEHICLE MIGHT CATCH FIRE BUT TESLA WON'T ANSWER THESE QUESTIONS AND NEED YOUR HELP. THANKS

I EXPERIENCED A SUDDEN LOSS OF RANGE WITH 2019.16 SOFTWARE UPDATE THAT TESLA RELEASE. I NO LONGER HAVE THE RANGE OR CHARGING SPEED BEFORE THE UPDATE. THIS WAS A PURPOSEFUL ACTION FROM TESLA DUE TO THE POTENTIAL FOR THE BATTERIES CATCHING FIRE. TESLA TOOK ACTION TO DOWNGRADE HORSEPOWER AND RANGE ALONG WITH ALL OTHER ASPECTS OF PERFORMANCE THROUGH A TOTAL VOLTAGE CAP. THIS IN EFFECT HAS DEVALUED THE RESELL VALUE OF MY CAR BY REMOVING FUNCTIONS, RANGE AND CHARGING SPEED. THIS CHANGE HAPPENED WHILE THE CAR WAS PARKED IN MY GARAGE AND STATIONARY.

THIS IS IN REGARDS TO NHTSA ACTION NUMBER: DP19005 - INVESTIGATION SUBJECT : BATTERY MANAGEMENT SOFTWARE UPDATES TESLA PUSHED A SOFTWARE UPDATE TO OUR CARS IN APRIL/MAY OF THIS YEAR THAT SUBSTANTIALLY REDUCES RANGE AND POWER USING A VOLTAGE CAP THAT ALSO REMOVED ABOUT $30,000 WORTH OF PAID UPGRADES TO RANGE AND HORSEPOWER (ELECTRIC CARS NEED VOLTS FOR BOTH RANGE AND POWER, SO TESLA'S REDUCTION TOOK SUBSTANTIAL VALUE OUT OF THE CARS AFFECTED). TESLA CLAIMS THEY DOWNGRADED OUR CARS "OUT OF AN ABUNDANCE OF CAUTION" AFTER A SERIES OF CARS CAUGHT FIRE WHILE PARKED (NON-COLLISION, NON-PHYSICALLY DAMAGED VEHICLES, THAT CAUGHT FIRE FOR APPARENTLY FOR NO REASON - SOME AFTER BEING UNUSED FOR SEVERAL DAYS). TESLA INITIALLY CLAIMED THE UPDATE WAS REMOVING FEATURES WE PAID FOR "OUT OF AN ABUNDANCE OF CAUTION" BUT NOW TESLA WILL NOT TELL US WHETHER OR NOT THE ISSUE IS SAFETY RELATED. THIS IS A CRITICAL OMISSION, BECAUSE THERE WAS NEVER ANY NHTSA RECALL NOTICE POSTED, OR SERVICE BULLETIN, OR OTHERWISE SAFETY RELATED OFFICIAL INFORMATION. THOUSANDS OF TESLA OWNERS ARE CHOOSING TO SKIP THE UPDATE, BECAUSE IT CAN INSTANTLY REDUCE THE VALUE OF OUR CARS BY HALF AND MAKE THEM UNUSABLE IF PEOPLE BOUGHT THE RANGE UPGRADES OUT OF NECESSITY. DISTANCES THAT WERE ABLE TO BE DRIVEN BEFORE THE UPDATE ARE IMPOSSIBLE AFTERWARD. PURCHASES WERE CALCULATED ON THIS AND THE RANGE UPGRADES WERE MADE FOR THE ADDITIONAL RANGE THE SOFTWARE UPDATE REMOVES. PLEASE GO FORWARD WITH THIS INVESTIGATION. I WOULD LIKE TO KNOW: 1) IS THERE A SAFETY ISSUE? 2) DOES THE UPDATE ADDRESS A WARRANTY PROBLEM? 3) IS MY HARDWARE FAULTY? WILL IT BE REPAIRED? WHY WAS IT REDUCED? 4) ARE PEOPLE THAT DON'T CONNECT THEIR CAR TO WIRELESS INTERNET AT RISK FROM NOT BEING UPDATED?

ON OR ABOUT JUNE 24, 2019, MY PARKED CAR'S SOFTWARE WAS FORCIBLY UPDATED WITHOUT MY PRIOR KNOWLEDGE, WITHOUT ANY PRIOR NOTIFICATION AND WITHOUT MY AUTHORIZATION. THIS FORCED SOFTWARE UPDATE REDUCED THE NOMINAL CAPACITY OF MY BATTERY BY 16.02%. ON JUNE 23, 2019, MY 100% STATE OF CHARGE (SOC) WOULD CHARGE EACH CELL IN MY BATTERY PACK TO 4.2 VOLTS, RESULTING IN A RATED RANGE OF 256 MILES. UPON ENTERING MY PARKED CAR ON JUNE 24, I DISCOVERED THAT TESLA "CAPPED" THE BATTERY SUCH THAT EACH CELL WOULD ONLY CHARGE TO APPROXIMATELY 4.09 VOLTS, RESULTING IN A RATED RANGE OF 215 MILES AT A 100% SOC, OR A RATED RANGE LOSS OF 41 MILES. THEY ALSO SLOWED THE CHARGING RATE BY OVER 50%. FOUR TESLA CARS THAT WERE PARKED RECENTLY CAUGHT FIRE. AFTER THE FOURTH FIRE, TESLA ISSUED AN OVER THE AIR (OTA) SOFTWARE UPDATE PREVENTING THE FULL CHARGING (E.G., TO 4.2 VOLTS FOR EACH CELL) OF THE BATTERY PACK, LIMITED THE AMOUNT OF CURRENT THAT CAN BE "PULLED" FROM THE BATTERY PACK AT ANY ONE TIME, RESULTING IN A LOSS OF ACCELERATION. TESLA STATED THE UPDATE WAS "OUT OF AN ABUNDANCE OF CAUTION" AFTER THE OCCURRENCE OF SEVERAL NON-CRASH FIRES. TESLA UNILATERALLY TOOK THIS ACTION OF ISSUING A "FIRE-SAFETY UPDATE" WITHOUT INFORMING THE CAR OWNERS OF THE REASON FOR THE UPDATE, WHY SAID UPDATE SHOULD BE INSTALLED AND THE EFFECT ON THE CAR ONCE THE UPDATE WAS INSTALLED. IN MY CASE, THE UPDATE WAS FORCED ON MY PARKED CAR VIA AN OTA UPDATE ON JUNE 23 (OR 24) WITHOUT PRIOR NOTIFICATION TO ME NOR REQUESTING MY APPROVAL NOR INFORMING ME OF THE CONSEQUENCES OF INSTALLING THE UPDATE (REDUCED RANGE, POWER, ETC.), TESLA SAID THAT THEY WERE RELEASING A FIRE-SAFETY UPDATE, BUT OFFICIALLY NO SAFETY UPDATE WAS RELEASED.
