Working on the Car at home...

You have hella lots of batteries in parallel in an electric car, so you lose some top end performance with a dead cell, but as a rule, no, you won't be stranded unless the battery catches fire or something. Now, just plain running out of charge is another question...

you also lose a lot of charge time, i work with electric forklifts, when a cell goes in the battery pack, you lose operational time, which in an electric car means loss of range.
