When it comes to the insulation, we often noticed in Model X Performance vehicles of all years of construction that the HV cable in the lower trunk burns the factory insulation due to overheating. For one customer, this had even progressed to the protective coating.
We therefore recommend that all drivers of a Model X Performance check this point or have it checked. We offer a free check at our locations, which we also carry out automatically for all commissioned work.
Should there be any damage, this will usually be Fixed by Tesla under warranty.
