How so? The Chevy Volt has gotten the highest customer satisfaction rating of any car that GM has ever made and the Tesla Model S has gotten similarly high marks on customer surveys. The Nissan Leaf had some problems in Arizona until Nissan modified the battery to better handle high temperatures. Other than that, they have performed well.
There have been zero fires caused by Volts in the real world. There have been a few Model S fires but at a five times lower rate than the average gasoline car.
Oh, they're fine....unless you want to go somewhere, or run the headlights, and the heater, and the wipers...in a cold climate.
I've seen one (1) in my life.
It's probably not too far fetched to believe: that since the Volt is the pride and joy of Gubmint Motors, and since it's very likely that the bulk of purchases are from federal, state and local governments, that therfore, those nameless, faceless, overpaid/do-nothing bureaucRATS would of course give the Volt golf-cart high "customer satisfaction ratings".
