Vehical infotainment system constantly beeps and changes formats, including randomly dialing phone numbers while driving. turning volume down does not control the distraction and system cannot be turned off. beeping is so load, it can be heard from 20 feet away from the car (outside of vehicle). the distraction is a safety problem for the driver. problem is in effect over 6 monthes and unit cannot be replaced due to product unavailability.
There is a known issue with certain Subarus where it is phantom draining the battery. I replaced battery in 2021 with AutoZone after being stranded. It too doed in June of 2022. I replaced it again. In Dec 2022 it started to die and found out about the class action lawsuit. I went to Subaru and they said since I already replaced the OEM battery, they couldnt help me. This should be a recall. I called Subaru of America who told me they couldnt help me and there is no fix as of today for the draining of the battery. They know about the issue. Why isnt there a recall?
In the past 6 months, the electrical system of my 2018 Outback has completely shut down on at least 4 occasions. I required several jump starts with the car parked in the garage, no doors left open, and no lights left on. I took it to the dealership where I was basically accused of lying because I “must have left something on”. I tried to assure the staff that I did not. They gave me a new battery and 4 weeks later I walked out to a dead car again today. I started searching online and found that Subaru is well aware that this problem has been a frequent occurrence with Outbacks dated 2016-2020, and there is a class action lawsuit against the company because they have failed to issue a recall. After my husband figured out that something must be pulling on the battery, we turned off all the safety features of the car. Within 7 days of turning them back on, the battery was dead. I specifically bought this car for safety reasons. What good is it if I can’t use the safety features?
Battery died prematurely and failed to hold a charge had to be replaced 4 DEC 22, for 194.63 from Advance Auto parts, Battery had failed to hold a charge in the past and Subaru roadside assistance had to be called on a previous occasion to issue a jump start.
My 2018 Subaru Outback battery is draining practically every day now. There must be something in the car that drains the battery constantly so in the morning I am unable to start. I needed to jump start the battery on multiple occasions now.
In early September 2022, my friend, who owned a 2019 Subaru Outback, needed a AAA tow because the battery died. He told me that battery failure is a common problem with Subaru 2016 - 2020 Outbacks. I researched that assertion and found it well documented. Because my Outback was 4 years old and my family was planning a trip, I decided to replace the battery at my mechanic's shop (Sept. 14, 2022). On the night of December 29, 2022, upon exiting a restaurant with my wife, my car would not start. A patron of the restaurant came to my aid, and we jump started my car. My car ran for 30 minutes but would not start the next morning (December 30, 2022). I then jump started my car using my wife's car battery, and let the car run for an hour. It would not start immediately after shutting it off. My wife called Subaru, and the representative she spoke with gave her a case number to use at the Subaru dealership. The dealership gave me a January 2, 2023 appointment, and after jumping my car again, I brought it to the dealer. Later that day, by telephone, I was informed: 1- there is no fix for the problem in the 2018 Outback; 2- I was not due any compensation for the 3 month old dead battery because I did not purchase it at Subaru, and 3- that battery was barely holding a charge after a few hours on Subaru's charger. I was advised to go back to my mechanic to see if the battery is under warranty. It is, but that is not the issue. Whatever is causing the battery drain in the Outback will drain the next battery. I was lucky this time-- I was not stranded. But who knows the next time? Who knows how many people are paying for new batteries only to have them ruined by the Subaru electric system malfunction? Who knows what kind of dangerous predicaments this malfunction might cause? Subaru is aware of this widespread problem, yet they are unwilling to publicly recognize it and issue a recall. There is something unscrupulous about this situation.
Battery drainage Have had to have vehicle jumped twice now. Battery totally dead when I tried to start car and return home after appointments. Afraid this may happen while driving which happened to a friend of mine! Very dangerous situation!!
The infotainment system freezes randomly causing screen to freeze including while backing up. This causes it to appear as though the back up camera is working when in reality it is not. Serious safety concern if cross traffic or children are not seen.
Battery keeps draining. I replaced the original battery 6 months ago and it just drained again
Battery draining issue. Jump starts required
The battery continually drains due to some electrical leak in the system (particularly when the rear liftgate is left up and the interior lights are on for several hours), requiring jump starting of the vehicle on several occasions. I have had the battery serviced and checked several times, at my expense, with results being the battery was okay. Eventually, I had the battery replaced by a Subaru dealer at my expense.
Premature battery drainage. This problem is well documented in existing class action lawsuits. My original battery was replaced under warranty on 9/10/19, Invoice #19682 from Van Bortel Subaru of Rochester NY. 17264 miles on odometer. MY wife and I were recently stranded with this replacement battery failing with less than 10k miles on it. There was no pre-warning of the problem. According to the internet, battery drainage is a problem with 2017-2019 Outbacks and Ascents.
I bought a 2018 Subaru outback in January of 2022 from a Subaru dealership. Approximately 3 months after purchase the car battery died suddenly with no prior warning, so I jumped it, it started fine and I drove it to work. When I took my lunch break 3 hours later, my car was dead again. I jumped it, it stated fine and I drove home. same thing happened when I tried to go back into work, and when I tried to leave work for the day. During my lunch break on the way into work the dash light and display screen shut off completely while I was driving this happened a second time when i left work on the way to an auto shop. At the auto shop they ran diagnostic on the battery and declared it dead, unable to hold a charge any longer. I then payed 250$ bought a brand new battery and got that installed. Here I am 6 months later and I am having the same issues with the battery. This is a safety issue what am I to do if the battery dies while I'm driving and leaves me stranded in the winter.
I bought this Outback new back in June of 2018. I just purchased the 3rd battery for it today 8/11/22. I’ve noticed that the past 2 batteries have been corroded and barely last 1.5-2 years. It sounds like this is an issue with many other owners as well where the battery either doesn’t fully charge or continues to deplete when the car is off and parked. The battery gets so low and is so corroded that it can’t get jumped by remote starters and requires a jump from a started car. The shop I took it to to replace the battery said they couldn’t get a read from their battery checker because the terminals had so much acid on them.
The battery loses its charge so that the car will not start if I don’t drive the car at least once or twice a week. The battery and electric system of the car was checked July 11, 2022 at the Bay Ridge Subaru dealership in Brooklyn, NY and all systems were found to be normal and good, including the battery. The battery is only 1 year old and is under a 30 month warranty. The Subaru service technician said that the car needs to be run for 45 minutes twice a week or this problem will keep happening and will lead to the battery needing replacement much sooner than normal. He also suggested I buy a portable battery jumper or a stronger bigger battery for $500-$750. So he acknowledged that this model has issues with the battery draining. He said the newer Subaru electrical system in Subaru Outbacks was first tested on this car model and year, and that was the cause of the problem, that they hadn’t figured out an efficient electrical system for the newer Subaru Outbacks by the time they started selling the 2018 Subaru Outback. The system is available to look at upon request. The problem was confirmed by the Subaru dealership service technician. The safety hazard is that I or my family might get stuck somewhere that is remote or dangerous due to weather or temperature with a car that won’t start. Or if I need to escape a bad situation quickly and my car won’t start. There were no warnings before the battery died. This has happened 3 times in the past two months. Today is July 11, 2022.
After purchasing my 2018 Subaru Outback, I experienced 2 instances where my battery died in the first 2 yrs of ownership. After the second instance, where it had died while I was eating at a restaurant, I contacted the dealership right away. They replaced the battery with a new manufacturer battery saying the previous battery failed the testing. I paid $176 for a new one. This was in March 2021. While preparing to return from my summer home in the mtns to my permanent home on the coast, I spent at least an hour packing my car and trying to keep the door and hatch openings at a minimum. Well, my car battery was dead while trying to start my car for my trip home. I had previously purchased a portable battery pack at the cost of $100 with me, and was able to get it started. One should not have to go such lengths when traveling as doors and the hatch are almost always being used. My car is going in for service at the dealership for this particular issue, but they are only going to replace the battery of which I have been informed. My car has 35,000+ miles and is only 4 yrs old. I traded in my previous car because it had over 100,000 miles on it. But I never had these kinds of issues with it. Now I am hesitant to travel anywhere unless I have that battery pack as it is deemed not reliable! This is ridiculous!!
Entertainment Unit Defects Car Battery Fast Drainage
Battery is dying pre-emptively. Have gone through 2 batteries in one month.
Subaru Starlink system flickers, selects apps and does all of this without ANY touching. At times, the backup camera is not working. Having a phone connected does not improve the problem.
Persistent battery drain. Car was jumped a week ago because it wouldn't start at all. It has been sluggish to start (turns over a couple times before catching) since and had a major error with the rear hatch today despite starting up. Power rear hatch will alarm as open but then cannot be opened with key fob, button in car, or button on hatch. The rear alarm will ring consistently until car has been running for 10 min/reached 60 mph but restarts again at stop lights. It is currently scheduled to be looked at in 4 days, if it is able to be safely driven to the dealership.
The car battery will drain completely when the car is not being driven. This has happened to us numerous times while camping leaving us in a remote area with a dead battery and no cell phone service to call for help
Electrical issues affected the battery becoming completely drained, unable to unlock doors, or start the car. This issue has become stressful and worrisome as I have a child and pets. I always have my baby with me and am anxious that I can't unlock the doors. I have taken the car to the manufacturer (dealership) for service three times. They've been able to identify the issue, however, the problem has reoccurred (now the third time). Warning panels would suddenly light up with different messages and the car computer did not retain the information in the last two incidents, however, recorded the information in the latest incident. The first time this happened was in December of 2021 (approximately 50,000 miles).
The electrical system in our Subaru is draining the battery prematurely, which could cause us to get stranded.
Just had to replace the battery for the third time since we bought the car in Dec 2017. This last battery was installed in Aug 2021 and failed Jun 2022. The dealer we take the car for service has not been able to determine why the batteries are failing so often. Fortunately two failed our house but once it failed at a store's parking lot and we had to wait for three hours to get a tow to the dealer. It's always failed parked, never while driving but I'm not sure it can't happen while driving.
Battery keeps dying in cold weather. I’ve charged it 3 times in the past 2 weeks fully and double check to make sure no lights are on when I leave the vehicle. The next time I drive again it’s dead
