Subaru Outback electrical problems

Over the last two-plus years I have found my 2018 Subaru Outback's battery dead or so low that it cannot crank the engine. I have had to replace the battery twice in that time, and have had AAA out at least four times to jump start the car without replacing the battery. Today, after sitting in my garage for about 10 days, the battery was so low that it would not crank over the engine. This is a truly unusual experience in my life. I have left cars at home or at the airport for several weeks while traveling, and had no problem starting the cars upon my return. My Subaru Outback completely drains the battery while parked with the engine off in as little as 7-10 days. It is as if some electrical system or circuit in the car is continuing to use battery power at the same rate as if the engine was running. I am fortunate that I have a 2nd car. If I did not, I would be screwed. Someone needs to look into this, identify the problem, and then require a fix.

The contact owns a 2019 Subaru Outback. The contact stated that the vehicle failed to start-up intermittently. The contact stated that the failure had recurred three times however, she was able to restart the vehicle by jumpstarting the vehicle. There were no warning lights illuminated. The vehicle was taken to the dealer where it was diagnosed that the battery needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 23,000.

Rear tailgate fails to open consistently making it impossible to enter or exit the vehicle from the rear, through the rear tail gate door (the 5th door). Nine times we have brought vehicle back to authorized Subaru dealerships over the last two years of ownership in Hanover Ma-Planet Subaru; San Francisco -Serramonte Subaru and lastly in San Diego- Kearny Mesa. The rear tail gate does not open consistently while pressing the open button on either of the key fobs or from trying the driver's side interior release button or while attempting to use the hatch release button at the exterior rear of the vehicle. Many times we have tried all three standard methods to open the rear tail gate but with no success making this rear tail gate feature on this mid size SUV useless. This problem has been verified at Planet Subaru, Hanover, Ma and at Serramonte Subaru S.F. Could not duplicate it at our last appointment in Kearny Mesa San Diego in 2022 but it still continues to be a real problem. On multiple occasions, the car battery had been inadvertently drained because the rear tail gate did not close completely and the dash warning light confirmed this to be the case. Subaru adjusted the closing mechanism/replaced it and this seems to have solved the closure issue but not the opening function of the tailgate. The problem surfaced soon after our initial purchase of vehicle in July of 2020. Car is available for inspection.

My battery has continually been dead, despite replacing the battery twice. I just had to call roadside assistance last weekend on Saturday. Yesterday (Sunday), the battery was dead again - 8 days later. This happened several times when I first got my car, and Subaru replaced the battery, as the car was still under warranty. I have since replaced the battery twice, and am still having the same issues. This is extremely frustrating, considering one of the main reasons I bought this car was for the reliability.

2016 Subaru Outback, original owner, the battery constantly drains in this car. I have come out to a dead battery many times, and have had to jump and service my battery several times a year. I have had my battery replaced at least once as well. This seems to be a constant issue, and after reading up on other owners of same and similar models, it looks like it is a software and electrical system issue. I am looking into the class action lawsuit, but think that this should be a recall and repair of these systems, as I must jump and service my battery several times a year. Thank you.

I believe there is a software defect associated with the infotainment system. The system also includes car information such as car data, audio/radio, navigation as well as other items related to modern car's functionality. The issue is when a mobile is plugged into one of the two from USB port, the infotainment will randomly reboot itself. When this happens the screen turns black/bland while rebooting occurs. This can happen even while the vehicle is in motion possibly causing severe distraction resulting a safety issue. (Imaging driving down the highway and your car reboots without warning.) Reboot takes about two minutes during this time the vehicle is drill drivable but is very disconcerting to the driver. This issue is also a major topic with online forums such as www.subaruoutback.org under the Gen 6: 2020-Future section. https://www.subaruoutback.org/threads/2020-outback-software-gigathread.517684/page-340#post-6235066 Attempts to reach the dealership has not proven to be resolvable.

The battery has gone dead 4 (four) times. The dealer checked it twice and said nothing was wrong with it. We have had to replace the battery ($178.07) but it also went dead. Three times, the car was in our garage, had been driven within a couple of days and the keys were not left in the car. Once it died when I had driven to the next town and had popped into a store for not more than 10 minutes and my husband had to leave work to come jump the car. We have found out that this is a persistent problem with some Subaru models and we feel the dealer did not disclose this. We now have to keep the car on a trickle charger ($74.18) and have to remember to disconnect when we leave and reconnect when we get back. Also, the passenger window cannot be lowered from the driver's side and the dealer didn't even look at it.
