We had one RAV4 EV driver here in San Diego already had his motor replaced with JdeMO, in addition to a cabin heater replaced up in Berkeley. It doesn't appear to be even a minor inconvenience for the dealers however for the cabin either they did ultimately charge 1.5 hours of labor to remove JdeMO (required to get to the cabin heater).
We offer a JdeMO Supplemental Instructions for Toyota dealers to replace the cabin heater.
