About 5 days ago on a short drive in my 2014 Model S (<80k miles) I started getting the error bms_w008 "Vehicle may not restart - service required."
I submitted a service appointment request and the service team actually asked me to come in earlier than my scheduled appointment.
They've now diagnosed the issue and said that the high voltage junction box is failing. "Normal operation of the vehicle is causing the current to jump up which is setting off the alert while driving. In the high voltage system it has to maintain 20 amps right now yours is spiking each time you drive because of road bumps and turns anything moving in the rear seat causes a tapping on this internal switch which is causing the current to spike."
I also recently had to have my 12V battery replaced and they said that they may have been related because the failure of the HV junction box would have left the 12V unsupported."
They've also shared that this is not covered under the warranty because "it is not a component of the HV pack it's just part of the high voltage system". She shared that "the tech did mention that he does see this often in the older Model S so he was pretty familiar with the part failure and was able to duplicate the concern easily."
Now, this is costing $1,607 to repair after paying $~250 for the 12V battery a couple of months ago.
Here are my questions:
1) The fact that is isn't covered under the 8-year battery warranty because it's not a component of the HV pack just a part of the system seems unreasonable to me. It seems like it's critical to the battery and to the drive unit. Am I being taken advantage of here?
2) If this is a relatively common occurrence is this likely to happen again?
3) Is there any other recourse from the failure if this is happening to many other older Model S vehicles? Should it be reported to the State of CA?
Thank you for any help!
