1 Car Will Not Start problem

Failure Date: 09/08/2021

Battery was completed dead after sitting for 2 weeks in my garage. The Subaru 24 hour road side assistance came and jumped the car, and told me to drive it for 15 minutes. Once I turned off the car, did my errands, and returned, the car would not start again. Had to have it towed to my dealership and Subaru replaced the entire battery. This car is only 15 months old with 3200 miles on it. I was told that I wasn't "driving it enough" -- but with the pandemic, where would I be driving? should a car that is so new experience these kinds of problems already?.

Parked the car at lakeside park and went for a hike. Returned 2 hours later and the car would not start. No lights or doors were left open. Finally called roadside assistance and they were able to jump start the car. There was no reason the battery should have been dead.

6 Car Will Not Start problem

Failure Date: 06/20/2020

With only 170 miles on the odometer, I went to start my Outback and it would not start. Had roadside assistance come and jump the car, which resulted in the car starting. I then parked it in my garage overnight. When I went to start it in the morning, the battery was completely dead and I could not even unlock the doors with the remote. I drink 10 miles round trip on an average day to/from work and had the car for a total of 4 days before this happened.

7 Car Will Not Start problem

Failure Date: 06/16/2020

I have had the car for only three months, and the engine has failed to start >5 times, while stationary. I have had to get several jump starts, and the battery will run again for a few days or weeks before seeming to die again. I took the car to an autoshop and they said the battery seemed fine to them, but the car continues to have failures with starting the engine. I have had safety features dysfunction while I was driving, and one of them led to an accident while driving on the highway. I have been stranded a few times, and lost hours from my job.

8 Car Will Not Start problem

Failure Date: 05/10/2020

My 2020 Subaru Outback was parked in my home garage from about noon on Tuesday until I tried to go at about 4 pm the next Sunday. The car would not start and there was no clear reason why. I called for road side service and made arrangements for them to come Monday morning to try a jump start and tow it into the dealer if needed. At that point, I had the car for 3 weeks and it had 2 mines on it. Monday morning I called the dealer to let them know of the problem. They suggested that I was not driving it enough and maybe I should get a battery tender to keep this from happening. I was not at all pleased with their suggestion and do not plan on following their advice. I did some additional research on the internet and found that this is a well known problem that Subaru and their dealers are unwilling to resolve. And, it seems that its not just the battery but several car components keep running after the car is shut off and that would run down any battery that is in the car. I need reliable transportation and this new car is not able to provide that.

9 Car Will Not Start problem

Failure Date: 04/04/2020

Battery is inadequate for the electronics in this car and will be dead if not driven often. After being a unable to start my car twice within a month, the service manager admitted this was a design flaw, there is no other upgrade or replacement for the battery and that the factory recommendation is to drive the car every other day. This means that when I travel and leave my car in an airport parking lot for a week or more, I will not be able to start the car when I return. The service manager told me to disconnect the negative post at the airport, then reconnect the post when I return. I am a 65-year old woman and not a mechanic. This car is unreliable and is a safety risk for me when I return to a parking lot late at night and my vehicle will not start. It has less than 5,000 miles.
