On january 2, 2019 between 1:45 and 2 pm i drove from my house into a clinic parking lot. as i drove my 2015 tesla model s forward and steered to the right into a parking spot, i consciously eased my right foot off from the accelerator pedal, thus lowering my speed from 10-9 mph to about 5-6 mph. the brake pedal was not pressed, allowing regenerative breaking to slow down the vehicle. about a second into the parking turn, the vehicle suddenly jolted forward, accelerating unexpectedly. i felt as if the brakes failed to work when i reflexively removed my right foot from the accelerator, and stomped the brake pedal as hard as i could. my vehicle came to a stop only after colliding with a chevrolet sports utility vehicle parked in the spot across. as i regained my bearings, i caught myself still flooring the brake pedal with my right foot, and continued to floor it until i after i had shifted it into parking gear, and made sure there was nobody walking in the vicinity. the impact from the tesla model s bumped the chevrolet suv parked in front about 5 feet back. the model s itself stopped between 2-3 feet into the next parking space, slightly into the opposing parking space on the right side, as seen in the included photos. this would indicate the brakes **eventually** worked. had they not, the tesla would have been expected to roll forward and into the suv's bumper after the collision. this is called tesla creep mode, which i have enabled (slowly roll forward while no pedal is pressed). i asked the police officer to position his patrol car behind my vehicle before i moved it and advised the police officer i did not trust the car. i used an app to call for a tow through my insurance, but the tow's number was disconnected. i was able to drive off with the patrol car in escort.
Software update crippled charging speed at superchargers
My car's charging speed was significantly reduced following a software update. i used to charge at 116kw until about 25% state of charge but now i barely get 90kw at that state of charge.
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.
April, 2019- my model s was stationary at a supercharging station, battery not charging normally, interrupting with error message: battery "recalculating". a 90% charge normally resulted in 242 miles of rated range. suddenly, a 90% charge now results in only 210 miles rated range. since new, the battery gradually lost a total of 3% of range, or 8 miles, over 3.5 years. suddenly, the loss of range is an added 15% or another 32 miles. the car now charges at a much slower rate. normal supercharger rate of charge starts at 116 kw. now, starts at only 60-80 kw. charging now taking much longer. i contacted tesla multiple times, with the above information. i have received no repair of issue after numerous attempts at receiving service. i've received many nebulous, conflicting, and untrue statements from tesla, refusing to confirm clearly what has caused this battery performance and charging problem. at one point, they indicated "the charging rate and your battery's capacity was limited to prevent over degradation of cells and damage caused by overuse of supercharging." another tesla rep stated it was caused by a firmware update, but no one has put that statement in writing. but, they still insist the battery has no problem, and needs no repair. if there is no problem with my battery then why did tesla cap it's voltage and charging rate with a firmware update? why will tesla not restore my car's performance? indications are such that either the battery should be repaired or replaced. considering that this firmware update coincided with some tesla battery fires, i am concerned that a faulty battery could present a dangerous condition. tesla has not been forthcoming with information, only refusing to repair the issue.
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.
