NHTSA Complaint #11417627 — 2018 SUBARU OUTBACK

My 3 year old outback is on its third battery. The first died when the car was 11 months old. Then in summer 2020 (car was 2 years old) I had to put in the 3rd battery. I installed an aftermarket battery since Subaru was closed at the time of the issue. Now this third battery is being inconsistent in starting or seeming as if there’s a dead battery. The battery, alternator, and starter, test as 100% functional. My dealership told me in a May 6th phone call that there was nothing wrong with my car, that I just needed a stronger battery. That would make the 4th battery in a 3 year old car. I was advised to purchase a charging jump pack and carry it with me every day. This is not a viable solution for a car that has to be jump started 1-2 times each day! Sometimes the issue is after long periods of driving, other times the car has been on short drives only. A local repair shop believes the issue is computer or fuse box related. My dealership disagrees. Yet I know that there are class action lawsuits against this model that read as if they are describing the issue with my own vehicle.
