Four time hard drive crash

I don't know where else to turn, I purchased Mac Book Pro in 2013 (late 2012 model). About 4 months ago it started shutting down on it's own and then not starting up at all. Took it to an Authorized Services Provider and they advised to replace the hard drive as it crashed. This then continued to happen three additional times! The Authorized Service Providers are dumbfounded themselves and suggested that I contact Apple. No, I have not abused my machine in any way. Has anyone experienced the same, any advice as to what I should do next? The amount of money I have spent replacing the hard drive on three separate occasions could have bought me a new Mac. Help. Thank you!
