I have enquired regarding the above in UK, but at present there is no detail.
Its an aspect to be considered with the new mainly Steel construction, and the previous Model S issues with component corrosion.
I believe the issues were dealt with swiftly by Tesla, and no-doubt lessons learnt, so I have confidence, but a Warrantee comparable with other quality Cars will be great. I'm sure it'll be in the details nearer THE date.
P.S. That new Tesla Grill will look GREAT on the Model 3
