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.
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.

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. see service record attached.
On june 27, 2019 i brought my car to a tesla service center for maintainance unrelated to the battery or drive unit. during the visit tesla downloaded a new software revision to my car that immediately limited range, power, charge rate and battery capacity. i noticed this and brought the car back to have the battery checked for damage, not knowing that tesla had purposefully throttled my battery. tesla told me that my car was limited via software because of age and offered no further explanation. i felt this was unacceptable and began to search for the reason tesla would limit my battery. this is when i found out that several tesla's in the age range of mine had spontaneously caught fire and many others had been limited via the same software update as mine. tesla needs to replace these faulty batteries, not limit the use. that is not the appropriate solution.
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. see, for example: https://www.theverge.com/2019/5/16/18627746/tesla-fire-battery-software-update-model-s-x https://jalopnik.com/tesla-is-updating-battery-software-after-a-model-s-catc-1834794877
It was a 2hr45min drive into work on an icy blizzardy morning, driving my 2013 model s rwd p85 with 90,000mi. have owned this car for 4 yrs. made it to work safely and the last 6 feet in the parking garage, going about 3 mph pulling at a right angle into a parking stall. had brake pedal depressed, shifted my foot to tap on the accelerator to inch forward and next thing you know, car is accelerating full throttle into a cement wall. crashed head on and airbag didn't even deploy. sat for a moment to catch my breath and try to process what happened. sent "bug report" on to tesla central from the car. the dashboard had prnd lit up in red and the vehicle would not go into drive or reverse. accelerator pedal was completely limp. zero resistance. thankfully, no other car was around me. called tesla service and they told us to reboot the car. we did, but accelerator pedal remained completely unresponsive. had to push out of the 5 story garage and tow it to an autobody shop. filed police report. reported to local tesla service center immediately. a few days later, we heard back from the tesla rep that said that report showed no malfunction. according to tesla accelerator went from 0% to 88% suddenly, implying "driver error." yet they also said the brake was tapped and then released prior to impact. this does not jive, why we a person accelerate, tap the brake then release? skid marks from rear tires left on garage floor. tesla won't release data. we do not want to accept this report and this is not what happened during the crash. today the auto body shop informed us that they were curious why the car is not driveable. after being reset, they discovered the accelerator pedal is broken. experience during the crash, combined with very unusual car behavior, and a broken accelerator refute tesla's claim of operator error.
Here is a tesla in the junkyard: https://www.iaai.com/vehicle?itemid=25626248&rownumber=65&loadrecent=true&isnext=true it has been completely burned out. the airbags have not been deployed. the front lh wheel is pushed back in the wheel well and that could have caused the fire by making the coolant leak out. if the battery pack is hot from recent charging or from hard driving it is highly likely to catch fire if coolant is lost. teslas seem to catch fire more often than any other electric vehicle. please investigate.
Needed to replace drive motor, 85kw battery in the last 6 months and currently have faulty onboard charger and not able to charge. these frequent charging problems have really annoyed me. tesla service has been really nice and responsive, however, i decided to report these because the issues are beyond what's expected from a new car, let alone a tesla. this is less than reliable for a 1+ yr old car. if it wasn't for the extension of tesla drive train and battery warranty (unlimited miles) these would have been really expensive repairs. *tr
A stolen tesla crashed in west hollywood, killing the driver. photos seem to suggest that the driver side air bag may not have deployed. allegedly light poles split the car in half. the light poles seem to be the breakaway type. suggesting there may be a structural weakness that allowed the tesla to break in half, fracturing the battery, catching pieces of battery on fire, and exploding battery cells, sending flaming shrapnel through the neighborhood. *tr
Tesla model s. has problems that with little or no notice the car can quit, leaving the car and occupants stranded dangerously in heavy traffic, sometimes with no lights. allegedly the traction battery, drive unit, contactor, inverter, converter and/or 12 v accessory battery can suddenly fail causing the tesla to quit with little or no warning, then coasting to a stop. allegedly in some cases after the vehicle comes to a stop the 12 v battery and systems will quickly fail, preventing parking lights and hazard lights from being used and preventing the parking brake from being released and preventing the engagement of tow mode thus preventing the vehicle from being pushed or coasted out of dangerous traffic to a safer location. not being able to engage tow mode, it makes towing the vehicle more difficult, time-consuming and risky. *tr
It is my opinion that, tesla is fraudulently misrepresenting statistics and the safety of its vehicles. it is my opinion, it is false advertising again. after the first tesla battery fire on october 1, 2013: on october 4, 2013 elon musk & tesla motors claimed "you are 5 times more likely to experience a fire in a conventional gasoline car than a tesla!" after the third tesla battery fire on november 19, 2013: on december 23, 2013 tesla motors claimed "tesla vehicle is over five times less likely to experience a fire than the average gasoline car" i think tesla motors is yet again using funky statistics to misrepresent and overstate the safety worthiness of its vehicles. after the third tesla battery fire, tesla was and is still using statistics that seemingly only figured on one tesla battery fire, rather than all three. *tr
