Tesla Motors' lineup of all-electric vehicles apparently has a problem that can pretty much guarantee people will be less than thrilled about it. If the battery is ever totally discharged, the owner is left with what Tesla describes as a "brick": a completely immobile vehicle that cannot be started or even pushed down the street. The only known remedy is for the owner to pay Tesla approximately $40,000 to replace the entire battery. Unlike practically every other modern car problem, neither Tesla's warranty nor a typical car insurance policy provides any protection from this major financial loss.
