Car Will Not Start problems of the 2020 Subaru Ascent

After being parked in the garage for several days the car failed to start. Upon inspection found the battery completely dead. Nothing had been left on that would have drained the battery, and have had no previous issues. Made several attempts to charge the battery, and the battery continues to fail to hold charge. Contacted dealer service department and Subaru of America. We are in the process of replacing the battery so we will be able to get the car to the dealership for diagnosis of the issues. Travel time to the dealerships are between 1 1/2-2 hours.

Battery drain. Parked car will not start even though the battery is less than one year old. It appears the oem battery is undersized or there are electrical battery drains when parked. Second time in two weeks that car will not start.

1600 miles and car will not start, battery keeps draining/dieing and radio stopped working.

The contact owns a 2020 Subaru Ascent. The contact stated that twice upon leaving the liftgate open for approximately 20 minutes, the vehicle failed to start-up after multiple attempts. The interior lights also failed to operate as needed. The first time the contact jump started the vehicle however, the vehicle failed to jump start after the second failure. The contact had taken the vehicle to suburban Subaru (14 hartford turnpike, vernon, CT 06066) where the mechanic was unable to determine the cause of the failure. A second appointment scheduled with the dealer. The manufacturer was not notified of the failure. The vehicle was not diagnosed nor repaired. The failure mileage was approximately 6,000.

Car would not start, was dead, it was in the garage, and there was no way to put it into neutral to roll it out. Had to call roadside assistance. They jumped the car after getting it out of the garage and was able to take it to the dealership.
