I bought a 2020 Outback Limited, used, 7 months ago (9/2022), 15K miles. Warranty expired February 2023. In April 2023 battery died after car was parked at the airport. Totally, completely dead, no clicks when pressing ignition. Jumped it. The next two weeks it died 3 more times. It would start after being off for 10 hours overnight, then an hour later it would not start. I would drive to work, then at lunchtime it was dead. Jumping it with portable battery jumper wouldn’t work, it would just drain the jumper battery. Jumping from a running vehicle would take over 20 minutes to get the engine to turn over. Dealer said it was a parasitic drain from a faulty DCM, though I am skeptical that was the issue with the randomness of when it would start or not start. With an expired warranty, it cost $1100. After TWICE arriving at dealership to pick up my “fixed” car and finding it was dead in the dealer’s lot, I managed to get them to replace the 700 battery with a 900 battery. Found out that this is the third battery in this car with 20K miles. So far, so good with the new battery, though if there’s still a battery drain, it will be dead again in about 7 months, I’m sure!
I’d like to know if you have a 2020 Outback where Subaru has replaced a faulty DCM under warranty. I’ve searched the forum, but I’m looking for this specific Year and issue. Thanks.
