I find this laughable. We're on our 3rd Tesla and we've never had anything even hinting of a reliability issue/getting stranded. There is absolutely no maintenance outside of consumables, which is really just tires, as the brake pads last the life of the car if you drive it as it's meant to be driven (regen); maybe windshield washer fluid? There've been a small number of minor things, like a seat belt tensioner on one of the three started rattling. They came and fixed it in my garage. 12V battery was on its way out on our oldest Tesla, car gave a message ahead of it dying (so, proactively avoided leaving us stranded by using software to interpret collected measurements), Tesla came and replaced it in my garage in 10 min for free. New cars are supposed to get Li-Ion 12V batteries soon standard, so the company is purposefully improving reliability. (Note: yes, Teslas have a 12V battery for auxiliary/emergency power, i.e. in case you run the EV battery all the way down you can still operate door locks etc).
Just doesn't add up calling cars that are known to intrinsically be super low maintenance and have much lower part count/complexity unreliable. Everyone I know who drives a Tesla has the same experience: zero maintenance, replace tires every 30-40k miles or when you get a flat and that's pretty much it. One of the main reasons I highly prefer EVs is because of reliability and lack of maintenance. Something seems fishy here.
