Four problems related to battery dead have been reported for the 2021 Subaru Outback. The most recently reported issues are listed below.
After 5000 miles my battery has been drained and is currently dead. I was told I must lock it every time I am not driving to ensure battery life is extended. Even with doing this battery is still dead after barely 5000 miles.
Vehicle was purchased less than 5 months ago, has less than 1000 miles and the battery has died. Car is used regularly, as a family car, to run errands in our neighborghood. Battery does not hold a charge. It will charge with a battery tender, but will then drain quickly.
Purchased the car 7 days ago. Drove approximately 50 miles so far. Went out to start the car this morning and the battery was dead. No lights had been left on. Car needed to be jumped.
I bought a new car in December 2020. One day in Jan 2021, I noticed that the battery had died. I jump started it and then in February 2021, I had to jumpstart it 3 times. At least the last instance, I was careful to check no interior lights were on, and it still happened. I went to the dealer and they replaced the battery. I hope that fixes it.
