I know the modern concept of EV is relatively new...
The big 4 might stand more of a chance with EV due to an established dealership/service network...Tesla won't establish dealerships in smaller/rural areas and the vehicle you are driving is non-existent here...If anything were to happen with a Rivian here, there is nowhere to take it for any sort of service...that is a huge selling feature...it could be the best vehicle on the road but if a person can't buy one locally or get it looked at if it ever has an issue, it won't sell.
Our local Ford dealership is sitting on rows of EV and hybrids that aren't selling....the owner of the dealership is getting a little worried about that as he has a lot invested in them and Ford won't take them back....
There are many Teslas around here and the nearest dealer is over an hour and half away....when something happens to them, they have to be flat-bedded to the dealership....this has happened to a person I know and they were told to rent a car and Tesla would cover it.....the problem is at the time there were no cars to rent....so they were told if they need to go somewhere to take ride-share or taxi and Tesla would cover that....
Not a very convenient prospect and the car was gone 2 weeks before they got the part to fix it....this person relied on family and co-workers to get them around in the mean time.....not good when they paid a premium for their car.
My son bought a Hyundai Sante Fe hybrid and got rear ended, it wasn't a huge hit but did $12k in damage and what he has found is his hybrid system is now intermittent....after the dealership took a look, they found some sort of coupler is broken but it is on the battery side so the battery needs to be replaced....the estimate to repair the car has doubled....they are letting him drive it and have disabled the hybrid system as it might take a few months to get the parts to fix it.
On top of that, when he bought it, his auto insurance premium went up about $1000 a year over his previous vehicle....
