Subaru Outback electrical problems

After leaving this car in an airport parking lot for 4 weeks, it would not start. I also noticed that all of the doors except the hatchback were unlocked. I coincidentally had a jumper battery unit in the car and was able to start it with the external battery jumper. When I drove the car the 30 minutes to my home, I found that the battery had not charged at all. This meant that until Subaru fixed this on warranty, I could drive the car but would have to raise the hood, hook up the external jumper unit, start the car, disconnect the jumpers, close the hood and finally drive where I was going. This procedure grows old after doing it repeatedly to shop for supplies after being away for 4 weeks. The Subaru dealer fit me in the following day and confirmed the battery had been destroyed by the car sitting unused for 4 weeks. He recommended that I always leave a small charger on it whenever it will not be used for 2 weeks or more! That would have been impossible at the airport parking lot. I have taken this car on very many severe backcountry drives where failure to start when it's time to leave could be problematic or even fatal. Whatever is the problem should be fixed. If the new battery will fail the same way, it should be replaced with a battery that won't, on warranty. If it's the charging system that's at fault, then the faulty design should be corrected.

Purchased my 2017 Outback in 2016. I have had FOUR batteries in less than four years. We were stranded in the middle of the night on the freeway hours from home, for a problem that has been ongoing. Each time the dealer has given us a new battery instantaneously. Ironic, that they claim there are no problems, when this issue is well documented online. No warning, but each time different symptoms. Hatch beeping unexpectedly, car won't start after short trips, etc... First time was only 9 months after first purchase of vehicle, 2nd time was a year and a half later, 3rd time dealer downloaded software patch, and battery still didn't last past 22 months. Thankfully battery is warrantied 36 months. How many complaints does the NHTSA need for further action? Isn't two lawsuits enough?

Battery failed prematurely. Vehicle purchased in December 2018. Battery totally failed in February 2021 with only 22,576 miles on car. Battery charged at repair shop. Battery failed again and was replaced on March 15, 2021. Battery failed again on April 29, 2021. Subaru of Oregon in Medford service representative replaced the battery again. He said the battery put in on March 15 was faulty. Had that battery tested at independent repair shop. The tests showed nothing was wrong with the previous battery. On June 15 had to recharge the battery again. Concerned about being stranded due to battery failure. The Outback must have an electrical issue that is draining the battery (per class action law suit Amy Burd, et al, v. Subaru of America Case No 1:20-cv-03095, US District Court, District of New Jersey) Subaru of Medford denies problem

The battery completely dies after at-least 3 days of not driving the vehicle. Within a few weeks of driving the car off the lot in 2017 (new from the dealership), the car would not start after not being driven over the weekend. I had the car jump started. It happened again the next week after a long weekend of not driving the vehicle. I had it jump started the drove it to the dealership. I was told there was nothing wrong with the vehicle or the batter. It happened again the next weekend and I had to get it jump started again. Since then I have not left the car un-driven for more than a couple of days. On June 18, I took the car for an oil change and was told i needed a new battery. I replaced the car battery that same day. Hooked everything up and the car started just fine. I check all interior lights and headlights to make sure they were all off. The next day, I go to start the car and my battery is completely drained. There is an issue with the car where it is draining the battery. I don't know if replacing the battery caused some kind of software reset, but now i'm having issues with a full brand new battery being drained overnight.

While driving near my home on June 5, 2021, the vehicle simply shut off and simultaneously all the warning lights flashed. I was unable to restart the vehicle after two or three tries. I called a tow service. About an hour later, before the tow truck arrived, I turned the key again, and the car restarted. This occurred in the middle of the roadway and I was lucky no vehicle was being behind me, as a collision could have happened. A local auto repair shop looked at the computer code and found one for a cracked gas cap. The mechanic replaced the gas cap, but stated that it could not have caused the car to cease running. I took the car to a Subaru dealer on June 14, 2021, but the service consultant stated that looking for the problem would be like "going down a rabbit hole" and told me to continue to drive the car until another incident happened.

Car was purchased 2/25/19. At 6,824 miles (10/28/19), our car began to no turn on. After a 3-4 times of jumping it, the battery stopped responding to the jump. Subaru had to tow it from our house because the battery was totally done and they couldn't even start it. Subaru said that the battery was defective (or might have a larger issue with the electrical system in their words). They replaced the battery and it began working again (7,000 miles - 11/4/19). Now, at 13,808 miles (6/16/21) - we've had 2 more instances in the past 2 weeks of the car not starting. In addition, the passenger side window no longer operates from the driver side door. We are confident that these issues are not being caused by lights left on, etc. We are taking it in again for another inspection. I have come to understand that this may be a design flaw with the electrical system including the 2019 Outback model.

On 8/30/2018, the car wouldn’t start after it was driven to a parking lot. The battery was jumped, car taken home, and then the battery was charged at local car parts store. On 6/7/2021, the car wouldn’t start after two days of no use. The battery was jumped and driven for 30 min. On 6/12/2021, the battery was replaced, and driven intermittently 6/12 and 6/13. On 6/16/2021, the car wouldn’t start with no panel or indicator lights working at all.
