Surge/ARC protection?

Hi folks,

So I’m researching my state’s Lemon Law, and trying to figure out how my longest EV system repair incident (of 5) fits into the picture.

The dealer said my charging port was burned by a worn-out charger, and they also said mine was the 5th or 6th car to come into the service center with this issue after using a specific set of public chargers. As a result, the $5K repair was not covered under the warranty. (My insurance did cover it, though.)

Since that repair was completed, my “service EV system” warning lights have come on at least three times, and the car has stopped charging. (I posted about this below.)

I could argue: “Hey, there have been five separate incidents where I’ve lost use of my vehicle because it won’t charge. The law only requires 3 incidents of a dealer failing to repair the same issue, so please buy this car back.”

But I could see them saying, “No, a burned-out port is different and it wasn’t our fault.”

To me, it seems that an EV should be designed to protect itself from a faulty charger, no? What systems are in place to protect a car from surges, arcs and worn-out diodes or whatever on a charger? If it’s a design flaw, it seems safe to argue the burned-out port is another “EV system failure” incident.

Thanks everyone!
