2017 Veloster with 28,000 miles-With no warning or any sign of trouble the car wouldn't start, battery was dead. Called AA for jump, they said battery needs to be replaced. Stranded late at night left little choice but to say ok, and was charged $180. Why would the battery die after just over 2 years from brand new? It should be under warranty, right? Will the dealer reimburse the cost of having it replaced by AA? Is this an indication of an electrical issue? Is this common? Thanks for any input.
