I would hope that EVs will prove more reliable than ICE cars .... when you consider how many of the ICE related issues are around the add-ons designed to make them cleaner....EVs have a head start, what with them avoiding all the egr and variable this and that by their nature .....of course scarcity of critical materials may cause them to be built to a compromise when they need to be produced by the millions..... my cynical nature says that current cars are built to a break point of reputation vs production cost..... and once the gloss is off EVs will be manufactured to the same ethos and will be much the same in terms of reliability .... tho legislation regarding longevity and repairability to counteract the damage of the 'throw away society's might help, and is long overdue.
