This complaint may refer to the reference number provided below: nhtsa action number: dp19005 - investigation subject: battery management software updates to whom it might concern, back to may 2019, tesla pushed a software update, firmware number 2019.16.2, to my car via over-the-air(ota) method. right after installing it in my car, i noticed there is a significant drop in the car's range. software version 2019.16.2 was released after several non-crush fires happened worldwide on the battery pack with the same size and spec as mine (85 kwh). new software capped the max voltage for both charging and discharging the battery, to minimize the chance for the battery getting overheated but in the meantime reduced the car's performance and range that i originally paid for. in the meantime, the hazardous for the battery catching fire has not been fully resolved. tesla service team declined my service request and keeps telling me that my battery is "operating normally" and refuse to provide any more information regarding this issue while i have to suffer the inconvenience caused by the reduced range and charging speed. plus i have to keep the car with the battery may catching fire anytime idling on my driveway outside my house where i and my family lives in. the battery losing almost 20% of capacity is not acceptable as "operating normally" and should be categorized as "failure parts" which need immediate replace under warranty (8 years, unlimited mileage, mine is expiring 12/2020). if the range loss is a precaution method for the fire situation, tesla should notify the affected owners and come up with a permanent solution for this issue. with tesla's attitude of refusing to communicate with the affected owners or providing any information on this matter, i urge nhtsa to start an investigation and provide us a definite answer. sincerely *tr
The right rear door handle became non-functional when attempting to open the car from outside the car. after service by the manufacturer (tesla), the door handle became exteriorly functional, although to a decreased amount compared to optimal performance, but was left in a state of inoperability from the interior of the car. pulling on the door handle from the inside would not open the door. in the event of a crash from the left side, the passenger in the right rear seat would be trapped without recourse.
