The dealer has refused to cancel the lease.
I talked to a California Lemon Law attorney today [...] The problem has to be subject to repair two or more times by the manufacturer or its agents, and the buyer or lessee has at least once directly notified the manufacturer of the need for the repair of the problem as provided in the warranty or owner's manual.
Thank you for your update Senqua.
MB B EV and Toyota Rav4 EV share the same Tesla drivetrain (motor, firmware and battery technology)
Mercedes started selling the MB B EV in the U.S. July 2014.
Toyota sold the Rav4 EV from 2012 to 2014, there are approximately 2,500 of them on the road today.
Toyota is doing a recall because of Tesla's drivetrain issues that can cause the car to suddenly shift to neutral. But note, phase 1 of this recall was announced, but they don't yet have a fix for the problem!
May I suggest you do the following:
* You probably already have done so, read these threads thoroughly:
a) LIST: http://www.mybclasselectricdrive.com/forum/viewtopic.php?f=8&t=380
b) Lost of drive: http://www.mybclasselectricdrive.com/forum/viewtopic.php?f=8&t=359
c) Drivetrain: http://www.mybclasselectricdrive.com/forum/viewtopic.php?f=8&t=374
* MBUSA is the decision maker, so write to them. Do as your attorney suggested, create a paper trail, write to MBUSA and Cc appropriately (including your dealership, and I would suggest also include the CEO & CTO of Tesla Motors). aloizi98 wrote to MBUSA and he received the desired results.
* File your case with NHTSA:
http://www.mybclasselectricdrive.com/forum/viewtopic.php?f=7&t=370&p=2928#p2928
* Let your dealership's service department try to: 1) identify the problem, and 2) fix it.
We can't say for sure, but based on your description of the incident, it's possible they will say you need a new Tesla drivetrain, or they will say they can't identify or reproduce the problem. Please let us know what fault codes they were able to retrieve.
* Show MBUSA and your dealership this forum and show them the relevant threads and posts.
* Educate them on the drivetrain defect and the status of the Toyota recall, especially the Toyota PDF file TonyWilliams posted on this forum. Tony is an expert in this issue and he is a very active member on the RAV4 EV owners forum ( http://www.myrav4ev.com/forum/viewtopic.php?f=7&t=1558 ).
a) Toyota's defect information report:
http://www-odi.nhtsa.dot.gov/acms/cs/jaxrs/download/doc/UCM474877/RCORRD-15V143-3968.pdf
In it, they described the sudden shift-to-neutral problem: "The Electric Vehicle Traction Motor Assembly in the subject vehicles is part of the propulsion system, which contains a drive inverter (DI), DI electronic control unit (ECU), electric motor, motor speed sensor, shift control actuator, and transaxle assembly. The motor speed sensor detects the electric motor speed and rotational position, and sends this information as a signal to the DI ECU. Due to a software issue, the DI ECU may not be able to determine the rotational position of the motor, which causes a speed sensor error code. This will trigger a “Check EV System” warning message on the instrument panel, turn on a malfunction indicator lamp (MIL), and cause the electric motor to shift to “neutral”, resulting in a complete loss of drive power. A complete loss of drive power may increase the risk of a crash."
And on page 3 they said: "November 2014 - February 2015. Additional reports were received, and the supplier continued to investigate the cause of the loss of drive power. During further investigation, the supplier determined that hardware variance is larger than firmware (software) tolerance. This can cause the drive inverter to be unable to determine the rotational position of the motor. If this occurs, a “Check EV System” warning message on the instrument panel will be triggered, a malfunction indicator lamp (MIL) will come on, and the electric motor will shift to “neutral”, resulting in a complete loss of drive power."
