MacBook Pro Mid 2015 bulging battery twice!

Is anyone else experiencing issues with bulging batteries on newer models? This is the second time in a year I've had to have my notebook fixed. The first time I took it in was because I couldn't physically press my trackpad down. The trackpad worked except for this situation; it felt stuck. They had to take my notebook for repairs and said it was a battery issue. I'm now having the same exact issue with my MBP and I won't be surprised if they tell me it's the battery again. What gives?
