Even slight drain on the battery is enough to cause hard and no start issues on this car. Further, these are not maintenance-free batteries and while your car is a 2016, its possible that you have an electrolyte imbalance due to a port/dealer prep error. If you don't have a multimeter, or don't feel comfortable checking the battery, get a known good battery from a friend's car and plop it in to see what happens.

Our batteries suck ass, the BR-Zs specifically have more instances of there batteries becoming useless at the 4 year mark due to there accessories while the car sit vs the FR-S. It's worth the upgrade to an optima red top, the CCAs will be almost double the stock battery.


Also if subaru sits on there ass, I suggest going to an independent tuning shop or someone with an OFT to actually read your cal id and see what's up
