Of course, you can get a new battery, and I recently had a new battery 80% covered by the dealer, since this is a very well known and documented problem. (My battery was going on 6 years old, so I felt like the discount made it a good time to replace it anyways. The discount was specifically because it is a known issue, and supposedly the new battery is more powerful and “solves” the problem, per the dealer.)
Pros: more powerful, solves problem
Our household got its first EV earlier this year, mainly for the daily 20-25 km commute form my SO, and it’s been the best car purchase we’ve ever made (only bested by my 3, which made it to 10y w/o problems this year). That “small battery” that once worried us (or more like we intentionally went with the smaller offering)? Barely a drawback - in the summer, a single charge lasts a whole week. This EV has become our go-to for short trips, and while cutting running costs by 2/3 was a big motivator, it’s now just a nice side benefit. I love the torque and started to love the silent driving. especially in a traffic jam.
Pros: love the torque, silent driving
Vehicle:
Mazda 3
I have a 2019 got a discounted replacement battery at the dealer and the new one is much larger (more powerful?).
Pros: larger, more powerful
OEM Subaru batteries and not the best. When it's time for replacement go with a 3rd party battery.
Pros: 3rd party battery better
Cons: OEM not the best
My car was sitting in parking lot with engine OFF and ignition ON - Android Auto was working and headlights/interior lights -> after about 15min music stops playing and I thought okay it's energy saver mode let me start engine.
But NOPE, there were some error messages, and engine couldn't start - battery was DEAD, I read battery are shit on new Mazdas and didn't want to deal with it myself and get it towed because of warranty.
Cons: battery dead quickly, no warning

Mazda OEM batteries known for underpowered and short shelf life. If you are in any kind of extreme climate for more than one season, there's a likely chance of failure.
