That’s Unusual For Any Car, But Any Car Can Have Any Part Fail At Any Time.
Was the functioning of the car’s electrical system checked to be sure there weren’t contributing circumstances ? A charging system with a problem can shorten a battery’s life.
Was it covered by a warranty ?
Do this. Look for the “date of manufacture” sticker on your car. It’s often on the driver’s door or door opening. Compare that to when the car first went into service (original selling date). If quite a bit of time lapsed (months) then that could contribute to a battery’s early demise. It could have lost its charge completely and had to be recharged and that isn’t very good.
Post the results of your search for dates of manufacture and original in-service.
