Re: nhtsa action number: dp19005 - investigation subject : battery management software updates the battery range on my vehicle has been capped via a software update by tesla without my consent. i was not notified that tesla would cap my battery's maximum charge, which in turn reduced the range and power of my vehicle via an over the air software update. the car was advertised as a 85 kwh battery, but now, with the battery cap, the battery is much less than 85 kwh. if there was a safety issue with the battery, tesla should have notified me. also, the battery should be replaced instead of having the safety issue still there and decreasing the performance.
I have a p85d and since recent software updates my range has dropped significantly.. my supercharger sessions have also become extremely slow resulting in almost an an extra hour to charge the car compared to before updates. these updates seem to be a makeshift cover for defective batteries due to high fire and explosion risk, which have occurred on other tesla cars. so instead of fixing batteries tesla reduced their capabilities across the board.
Shortly after updating the vehicle with tesla's software updates 2019.16.1 and 2019.16.2, it was discovered for the first time that the vehicle had suffered from a sudden and immediate loss of approximately 26 miles of range as a result of the pair of software updates. the updates in question also severely decreased the supercharging speeds for the vehicle. in addition, the software updates issued by tesla did not disclose anything with regards to the range loss or decreased charging speeds. tesla has released updates since initial range-reducing and charge-speed limiting updates which were supposed to and purportedly were issued to correct the problems, however, there is no significant change or increase in range or charging for the vehicle to date. note - this complaint has been submitted by legal counsel who currently represents the affected owner for this specific vehicle. legal counsel here also serves as counsel to the putative class members and named class plaintiff in the litigation currently pending in the u.s. district court, northern district of ca, case no. 5:19-cv-01422-vkd.
In may 2019 our tesla model s p85d battery charging capacity reduced from about a maximum charge of 248 miles to about 218 miles. tesla did not notify us that this would happen and after several phone calls and letters there has not explanation or information as to why it occurred.
This a complaint about the fatal tesla crash in fort lauderdale. even though the ntsb is investigating this crash the inquiry is likely to take more than a year. i am certain that this crash was caused by yet another suspension failure. http://miami.cbslocal.com/2018/05/10/ntsb-to-investigate-fiery-crash-of-tesla-in-ft-lauderdale/ crash scene photographs show that the rh back wheel and suspension have fallen off the car. the road is relatively straight at the crash site. there is just a single skid mark where the car suddenly went sideways. there is no indication of the car spinning out of control due to taking a curve too fast. the skid mark shows a very sudden swerve to the wrong side of the road and into the wall. the video shows what appears to be a detached wheel and tire lying in the roadway. it is also very concerning that teslas burst into flames so easily and that the electric door handles become inoperative preventing occupants or rescuers from opening them. once again the early stage of these fires seems to be fuelled by the 7 gallons of ethylene glycol. the stored energy in the batteries can easily boil off the water content of the coolant causing it to become highly flammable. the fire does not yet appear to have ignited the actual batteries since these burn with a white heat and the individual cells explode like firecrackers. this situation is extremely dangerous. please act immediately before more lives are lost.
Tesla s and x batteries are a design flaw. tesla's panasonic cells are made with thin metal casings so that the heat from one burning cell causes the neighboring cells to burst especially when exposed to air in an accident. these fires emit toxins such as florine gas. these cars should be recalled and the batteries replaced with a safer design. the recent accident in florida shows the need for this recall.
Here is a tesla in the junkyard: https://www.copart.com/lot/39926687/photos it has been totally destroyed by fire. there was an investigation into tesla fires back in 2014 and it was claimed that fires were caused by road debris puncturing the battery pack and this problem was solved by fitting a battery shield. teslas are still catching fire at an alarming rate. i believe that the cause of many of these fires is not that the lithium battery catches fire first but that the ethylene glycol leaks out and catches fire. the attache photograph of a 2013 fire clearly shows the coolant blazing beneath the car. a google image search for "tesla fire" shows many of these glycol fires. the lithium batteries may well ignite as well but in most cases it seems that the primary cause of fire is the glycol. advice to first responders should be modified because using water is not the best way to extinguish a flammable liquid fire. please investigate. concerned citizen.
The car gave a failure message and then lost all power. it shut down completely as i navigated through traffic in neutral onto the shoulder. i called tesla and was told this is a known software release bug. they said to turn off range mode and the issue will not recur. meanwhile they are working on a software fix. i believe that this is a life and death issue. it is being reported by many other model s p85 d owners on the tesla forum. i believe that tesla should immediately contact all owners as this issue is extremely dangerous and may cause serious accidents. please understand this - the error causes the car to shut down while driving and has affected many teslas already. it almost caused an accident in my case and will certainly cause a more serious event if not addressed. *tr
