Tesla has reduced the charging capacity and charge rate per: NHTSA action number: dp19005 - investigation subject : battery management software updates prior to this software update, the charge rate was double the shown rate.

After software update supercharging slowed by more than 50% and range on full charge dropped.

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.

The contact owns a 2013 Tesla Model S. The contact stated that the media control unit failed to function as designed. Additionally, the vehicle failed to achieve the estimated 210 miles per charge instead only achieving 120 miles. The vehicle was taken to Tesla (4361 granite drive, rocklin, CA 95677, 916-652-7740), where the media control unit was replaced however, the failure persisted. The vehicle was not repaired. The manufacturer was contacted and informed of the failure however, offered no assistance in replacing the battery. The failure mileage was 95,000. Invalid VIN.

While attempting to park the car in a parking space the car accelerated on it's own and crashed over a small concrete retaining wall and crashed into another vehicle. My car and the car that was struck were totaled.

Tesla pushed over-the-air software updates to my vehicle, which reduced the range the car could travel on a single charge, owners. The software updates, which started in may 2019, were made to fix for batteries that could ignite in non-crash scenarios.

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. Is this car at risk of non-crash fire? is it safe to park in my garage? since Tesla has refused to answer any of the above questions and only made vague statements implying a safety risk - to the press, not to me - I seek definitive answers from an NHTSA investigation.

Software updates by Tesla have limited range usage by lowering the available voltage max capacity for charging. 'parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6). '.

Nhtsa action number: dp19005 - investigation subject : battery management software updates - vehicle had sudden loss of battery capacity and charging velocity after software update in may 2019. This has continued with a roughly 15% reduction in the kwh rating of the battery (published rating 85. 0, actual 71. 65). I am disappointed with the reduction in the performance and usability of the car, but more concerned with the potential of an undisclosed defect or risk that I am am not aware of.

2017 Tesla Model S started to accelerate on its own over 100 mph, when traveling on highway around 70 mph, without autopilot engaged. As soon as it started to accelerate, the car took control over the steering wheel and drove into the guardrail on the left of the lane, then quickly steered to the right lanes and steered to the left again. Slammed on the brake but did not work at all, and steering wheel did not respond. The car completely took control over traveling over 100 mph going zig-zag on three lane highway, finally came to a stop after hitting number of trees in the woods on the right side of the highway. The car is completely totaled.

2013 Model S 40. Mcu failed due to memory card failure in December 2018. Car would not drive. Had to be towed. Car lowered windows by itself and could not be closed. Drained battery. Car could not be opened. Charged $2100 to replace mcu out of warranty. Mcu also failed on my 2015 Model S 70d [xxx] in 2019. Replaced emmc chip.

I was driving my Tesla Model S early in the morning in a quiet neighborhood when was slowly approaching to four-way stop sign intersection by gradually step on the brake. At the very beginning, I can feel the car decelerated, suddenly there was unintended acceleration that I felt. There was a jerking forward of the car, so I was not able to make a full stop at the stop sign. Then the speed drops down significantly, almost to zero. I pressed the flashing light because there was a line of cars behind me and I was in the middle of the road. The car was in almost zero speed, so I tried to move the car to the side of the road and pressed the acceleration pedal a little. The car didn't accelerate, instead, it turned into a stop situation. I realized I lost driving power of this car. I pressed the "p" button, then all four mode letters "p", "n", "r", "d" turned red, blicking. The car stopped close to the curb but partially in the middle of the road. I was able to get out of the car and called Tesla roadside assistance. They checked some log and responded with towing service to send the car to the service center. The overall situation could have turned very severe safety issue if ever this happened on the highway, or there was human being walking across the street while I was not able to fully stop the car, neither control it. I am waiting for official service report but the car is confirmed not in drivable condition. And I feel extremely unsafe to drive it now and even not comfortable to drive it after what just happened this morning. The entire drive unit was maintained and changed to a new one in 2015, so its life only about 3 years in this car. Plus, I just had the car service at the Tesla service center month ago. It is worrisome they can't even prevent such issue and detect it in an early stage, perhaps a design issue to address?.

The contact owned a 2014 Tesla Model S. While the vehicle was parked in the garage charging, it caught fire and burned at the contact's residence. The fire department extinguished the fire and police and fire reports were filed. There were no injuries. The vehicle was towed to a research center, but was not diagnosed because it was destroyed. The vehicle was not taken to a local dealer. The manufacturer was made aware of the failure and sent an investigator to inspect the vehicle. The VIN was not available. The failure mileage was 17,000.
