NHTSA Complaint #11419684 — 2016 SUBARU OUTBACK

For the past four years the car has insufficiently charged the battery. On two occasions the car would not start and had to be jumped. At first I attributed it to something I may have done like leaving an interior light on, but after the second incident I found out that other owners of the same car were having similar problems. I called the dealer and they said it might help to install a higher CCA rated battery.I replaced the original battery in 2018 with a higher rated Interstate CCA battery. That battery was also over time not being charged sufficiently and I took it back to the Firestone dealer who installed another Interstate Brand battery replacing it in 2020 under warranty. I called the dealership again and they said there was no reported issues with Subaru Outbacks insufficiently charging and that I just had to drive the car more frequently. So far the car has failed to start on 5 occasions, stranding either myself or my wife, twice in unsafe situations. I now routinely have to charge the battery in my garage about once a month to keep it operational, even after driving the car frequently. On 5/3/2021 I took the car back to the dealer for some service work. I asked again if there was any fix for the charging issue. They tested the battery and recorded that it "came up as deeply discharged". They said there was "No abnormal draw found ---vehicle charging normally."
