2015 Tesla Model S Fuel System Problems

The Model S, which was bought in 2015, had a sudden acceleration while I was trying to park near the entrance gate of the parking lot. The accident happened on May 25, 2023. Fortunately, nobody got hurt and the car was totaled. I feel strongly that this should be investigated, as this can be a very serious public safety issue. It was inspected by the insurance company. There were no warning messages prior to the failure.

The car will issue a BMS_w035 warning which is connected to the battery heater failing/failed. In this case, the car may not restart, per Tesla's on-screen warning. If this occurs while driving, or in stop-and-go traffic, this could lead to a dangerous situation of not being able to remove the car from the road safely without a tow truck. From recent incidents online, this is occurring in many 2014-2016 Model S vehicles with the colder weather change.

ISSUE 1). EVER SINCE I BOUGHT THE CAR I NOTICED THE DRIVERS SEAT FELT COOKED CAUSING LOW BACK PAIN. EVENTUALLY THE SEATS POWER ADJUSTMENT WOULD ONLY RETRACT ONE SIDE SO IT COULD NOT BE ADJUSTED EVENLY AND I HAD TO PAY TO HAVE A WHOLE NEW SEAT REPLACED ISSUE 2). I HAVE THE 85 KW BATTERY AND AFTER AN UPDATE MY BATTERY CAPACITY WAS REDUCED 10%. I WAS TOLD IT WAS DUE TO RISK OF OVERHEATING THE BATTERY FIRE RISK TESLA NEVER RESOLVED THE ISSUE AND NEVER REINSTATED THE MISSING 10% CHARGE CAPACITY 3). THE SUSPENSION HAD FAILED AS I WAS DRIVING OVER A SPEED BUMP LESS THAN 10 MPH AND THE BOTTOM OF THE CAR SCRAPPED THE PAVEMENT. I HAD TO PAY OUT OF POCKET TO REPLACE THE SUSPENSION

SOFTWARE UPDATE CRIPPLED CHARGING SPEED AT SUPERCHARGERS

NHTSA ACTION NUMBER: DP19005 - INVESTIGATION SUBJECT : BATTERY MANAGEMENT SOFTWARE UPDATES 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. *TR

A SOFTWARE UPDATE FROM THE MANUFACTURER HAS RESULTED IN A LOSS OF RANGE AND APPARENT RATE REDUCTION WHILE USING HIGH VOLTAGE CHARGING (I.E., "SUPERCHARGING"). THIS HAS RESULTED IN LONGER CHARGE TIMES AND RANGE LOSS. THE CHANGE OCCURRED WITHOUT NOTICE OR EXPLANATION OF NEED, AND HAS RESULTED IN SIGNIFICANT LOSS OF USE OF AN IMPORTANT FUNCTION IN LONG DISTANCE TRAVEL. *TR

SHORTLY AFTER A SOFTWARE UPDATE IN JUNE, 2019 I NOTICED THAT MY CHARGE CAPACITY HAD DIMINISHED SIGNIFICANTLY (APPROXIMATELY 30 MILES OR 15%). I RAISED CONCERNS ABOUT MY BATTERY KNOWING THAT TESLA REPRESENTS AN UNLIMITED MILE 8 YEAR WARRANTY ON THE BATTERY. MY BATTERY WAS TESTED REMOTELY AND I WAS ASSURED IT WAS NOT A BATTERY ISSUE. SHORTLY THEREAFTER I BECAME AWARE THAT THIS IS A KNOWN ISSUE AND ACTUALLY THE SUBJECT OF CLASS ACTION LITIGATION. I HAVE TEXT MESSAGES WITH TESLA GOING BACK TO JUNE, 2019 AND AGAIN IN OCTOBER, 2019 - THE DATE OF MY MOST RECENT SERVICE. TESLA HAS FAILED TO ACKNOWLEDGE A PLAN OF ACTION RELATED TO THE ISSUE AND WILL NOT "ROLLBACK" THE UPDATE. I WANT TESLA TO STAND BEHIND THEIR BATTERY WARRANTY AND MAKE THE NECESSARY REPAIRS TO ENSURE SAFETY AND PROVIDE ME WITH WHAT I PAID FOR. I HAVE ALSO EXPERIENCED SIGNIFICANT SLOWDOWNS OF CHARGING RATES AT VARIOUS SUPERCHARGERS.

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 DRIVEWAY AND STATIONARY.

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.

AFTER SOFTWARE UPDATE 2019.16.X LAST MAY, MY 2015 TESLA MODEL S 70D LOST AROUND 30 MILES OF RANGE. CHARGING TIMES WERE AFFECTED WITH THE CAR NOT BEEN ABLE TO CHARGE TO 100%. THE CHARGING AFTER 90% BECOMES EXTREMELY SLOW AND STOPS @97%. WHEN THE UPDATE WAS DONE THE VEHICLE WAS STATIONARY. I CONTACTED TESLA, BUT THEY REFUSED TO EVEN LOOK AT THE CAR, CANCELING MY APPOINTMENTS AND STATING THAT THIS IS NORMAL. AFTER LAST ATTEMPT TO QUESTION THE ISSUE I WAS TEXTED A MESSAGE THAT THEY ARE AWARE OF SOFTWARE ISSUE AND THEY ARE WORKING ON IT. THAT WAS ON JULY 24 2019.

HERE IS A TESLA IN THE JUNKYARD: HTTPS://WWW.COPART.COM/LOT/46203307/PHOTOS IT HAS BEEN INVOLVED IN A FIRE. THE ALUMINIUM BODYWORK HAS BEEN MELTED AND BURNED AWAY. THE BATTERY PACK APPEARS TO HAVE BEEN THE SOURCE OF THE FIRE. THE AIR-BAGS HAVE NOT BEEN DEPLOYED AND THERE IS NO SIGN OF COLLISION DAMAGE. THE INVESTIGATION INTO TESLA FIRES WAS CANCELLED AFTER TESLA FITTED A LIGHTWEIGHT TITANIUM BATTERY SHIELD AND RELEASED SOME VERY POOR QUALITY VIDEOS DEMONSTRATING THE INVINCIBILITY OF THE BATTERY SHIELD. THE RIDE HEIGHT WAS ALSO RAISED (FOR A FEW WEEKS) BUT SOON WENT BACK TO ULTRA-LOW. A GOOGLE IMAGE SEARCH FOR "TESLA FIRE" SHOWS THAT MANY OF THESE CARS ARE STILL BURSTING INTO FLAMES. PLEASE INVESTIGATE THIS PROBLEM BEFORE MORE TESLA OCCUPANTS ARE INCINERATED. THANK YOU. CONCERNED CITIZEN.

HERE IS A TESLA MODEL S IN THE JUNKYARD: HTTPS://WWW.COPART.COM/LOT/43880137/PHOTOS IT HAS BEEN TOTALLY DESTROYED BY FIRE. ELON MUSK HAS CLAIMED THAT TESLAS ARE MUCH LESS LIKELY TO CATCH FIRE THAN A GASOLINE POWERED CAR AND THAT THEY ARE NOW EVEN SAFER THAN BEFORE DUE TO THE TITANIUM BATTERY SHIELDS AND THE (TEMPORARILY) RAISED SUSPENSION HEIGHT. A GOOGLE IMAGE SEARCH FOR BURNED TESLA OR TESLA FIRE REVEALS THAT THERE HAVE NOW BEEN AT LEAST 20 TESLAS DESTROYED BY FIRE WHICH IS A VERY LARGE NUMBER IN PROPORTION TO THE NUMBER OF CARS ON THE ROADS. I BELIEVE THAT THE 7 GALLONS OF HOT ETHYLENE GLYCOL IN EVERY TESLA IS A HIGH RISK FACTOR. IF THE LITHIUM BATTERY ALSO BECOMES INVOLVED IN A FIRE IT BURNS INTENSELY AND IS EXTREMELY HARD TO EXTINGUISH. NO OTHER ELECTRIC CAR HAS SUCH A HIGH RISK FACTOR OF HAVING ETHYLENE GLYCOL CARRIED IN RADIATORS AT THE VERY FRONT OF THE CAR PLUS SUCH A LARGE VOLUME OF FLAMMABLE LIQUID COOLANT. PLEASE INVESTIGATE. THANK YOU CONCERNED CITIZEN.
