"The bms have detected isolation failures conditions on multiple drive cycles"


I have a Model S 85 2014. Nothing changed on the car, all original.
While on a long road trip (UK to Spain) the car gave me different error messages (picture below). A bit of drama, but I was able to take it to the nearest Tesla Service Centre in Barcelona, Spain.
Tesla UK told me the main error that caused the issues was "The bms have detected isolation failures conditions on multiple drive cycles"

The Barcelona SC recommended:
- 12v battery dead need replacement
- Rear motor needs replacement (1022562-00-B, 1025276-00Q)

Total 5,107 euros. (£4,402 $5094)
I had to fly to the UK with my family and agree on the repair.

Did this happen to any of you? Can you share your experience?

Many thanks!
