2018 SUBARU OUTBACK Electrical System Problems

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...

Entertainment Unit Defects Car Battery Fast Drainage

The battery has drained twice in the time that I have owned this vehicle. Once I was able to recharge the battery by jumpstarting and letting it run. The second time it required a battery replacement. This was approximately 12 months after the first incident. The electrical system also has unpredictable quirks related to the window functions and lighting. I am uncertain to other resulting irregularities that may be occurring under the hood. Currently, my car is being serviced for a radiator fan and motor replacement for the cooling system. The estimate for repair is $1747 + tax. This is potentially related to the electrical quirks related to the battery irregularities.

Battery failed and had to be replaced Wheel Bearing replacement

The battery in my 2018 Subaru Outback has been replaced three times since I purchased it. I am the sole owner. The original battery was replaced within seven months of purchase due to continual battery drainage. The dealership replaced it with the same type of battery and I was not charged. When I went into the dealership expressing concern with the second battery also having to be jump started frequently when the battery was barely two years old, I was told that is the typical life of a battery for the newer electronic vehicles and because the area I live in has excessive heat, that also lowers the battery life. I have had to jump start my vehicle so many times, I stopped taking my vehicle on long trips for fear of being stuck somewhere. In August of 2021, during a cross- states road trip, the battery died mid-trip. I...

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.

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.

Normal vehicle start. While leaving shopping mall parking lot, vehicle suddenly shut down; no electrical, no accelerator, no power steering, no engine. Was able to steer vehicle to safe location out of traffic path. Waited approximately 10 minutes, tried vehicle again, and it started / drove normally. Vehicle inspected afterward by dealer, who found no issues, and returned vehicle with no repairs made. Driver is 86 year old widow, who is terrified of being stranded in an unreliable car.

The electrical system in our Subaru is draining the battery prematurely, which could cause us to get stranded.

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...

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

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.

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.

The Battery of the vehicle drains frequently, making the car inoperable. The battery has been replaced three times in four years, much more frequently than i would expect in a relatively new vehicle that was purchased new from a dealership. The battery dies without warning and repeated jump starts don't charge it enough to maintain a change to the nexty operation. Each time the battery stops holding a charge the dealership advises me to simply replace it.

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...

Battery spontaneously drains, disengaging all safety features with no warning.

The batteries cannot seem to hold a charge. We have called AAA several times, but the recharging doesn't last, and they say this is a problem with the Outback. In addition, the Subaru dealer has replaced the battery twice. It just failed again. This most recent battery fail stranded my 70 year old husband in another city. I have contacted the dealer again asking for service. There is no warning whatsoever that the battery has drained. This is not a safe situation. The date below is the most recent incident of a drained battery.

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).

During a photography trip of May 2021, in a very remote area, the Outback's rear gate was kept opened for my dog for a few hours. When it was time to leave, the battery wouldn't start. Luckily, I had a battery charger. There was nobody present to help in this area and no mobile phone service available. Later in the day, the battery died again, under the same circumstance. We were fortunate to have extra food, water, and blankets if needed to survive the night. I thought maybe the battery was old. I replaced the battery on May 24, 2021 with an Optima 25 battery. This is a better battery than what Subaru installs. This February 2022, we went camping in a remote area of Death Valley with no available services. The fairly new car battery wouldn't start. I used my emergency starter again. This time the rear door and...

Bought the vehicle used from Carmax on 2/14/22, drove 25 miles home and parked in driveway. Next morning battery was dead, put a trickle charger on the battery and the charger detected only 4 volts and would not charge vehicle.

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

Battery continues to die. We have had our vehicle for a year and had to get to replace our battery 3 times including today! Multiple jumpstarts. Even had it die from leaving out trunk open once. How does that make sense?

I parked in my garage for 2 weeks, and I couldn’t start my car again. I had to jumpstart it. This is the third time it happened. The battery checked out fine. I drove around and now able to start again.

Battery continues to drain prematurely. It's been an issue since the very beginning of out ownership in June 2018. We replaced the battery after it would not hold a charge for more than two days. The replacement battery still wouldn't last for more than a day or two. Now in the cold weather it won't even last a day. Two days ago, I went in the grocery store for about 45 minutes and the battery was dead. I can't go anywhere without my portable jump starter.

Battery loses charge overnight for no reason. New battery placed in vehicle and same issue still present.

Battery is draining over time. Vehicle is now on 3rd battery in 3 years! Dealer replaced original battery during 2nd year and claimed it under warranty. Now that battery has failed and a different brand of battery has been installed (Dec 2021). Unknown cause of battery drain.

We have a 2018 Subaru Outback with 87,000. As of yesterday our car is now on its third battery. The original battery lasted about a two years, then we purchased one from Autozone, that battery only lasted 15 months. There is obviously an issue with the electrical system on these cars causing the battery to have a shortened life span. With so many electronics in the car it seems the battery may be to small, it is only a 25 series battery. It could possibly be there are issues with the electrical system cause constant drain. We do know that the car showed no real signs of battery failure before the battery is dead. No slow starting, dim headlights, etc. Both batteries were working well, until all of a sudden they did not. I have read online where this seems to be a real problem with these cars from 2016...

Battery will not hold charge

A week ago, drove 5 miles to get a hamburger. While the car was parked I listened to the radio. When my husband returned with our food 8 minutes later, the car would not start. The battery was dead. This happened again today (11/19/21) when we drove 4 miles and parked. I left the key in the ignition for barely 3 minutes before removing it, but the battery was dead when I tried to start it again a few minutes later. Both instances we used a portable battery charger after having the same problem happen during the summer. Today my husband took the car in to have the battery checked, but it is within normal range (12.2 volts). Aside from the battery problem, the oil lamp also comes on a lot…after getting a complete oil changed which should last us 6k miles or so, the oil warning light comes on...

I experienced premature draining of my car battery. I purchased the car in March 2021. It had approximately 19K miles and was in excellent/showroom condition. This is my first car with GPS and other advanced driving assistance safety features and collision avoidance systems. I'm still trying to understand all of these but some seem to have a mind of their own. I discovered the car's battery dead on the morning of 11/14/21. There was no warning that there might be a low battery problem and the car worked fine the previous day. I researched on-line about why this would suddenly happen and came across the Class-Action Lawsuit filed in April 2020 regarding these problems with Subaru Outback and Ascend models. I will also be contacting the legal team involved with the lawsuit, McKenzie Lake Lawyers, to verify if I need to take any steps prior to having my car fixed....

i own a 2018 Subaru Outback 3.6R Limited. In the last 18 months the battery has died three times while the car is parked. On the second occasion the battery condition was poor and I had to replace it. The third time occurred yesterday. Each time I have had to call for roadside assistance and wait, unable to start/use the car unti the help arrived. I have never had a similar problem with any previous car I have owned.

My new replaced battery just died again. The first one lasted 27 months and after Subaru replaced a new one, it died after 15 months. I did report on the first one too.

Battery died for no apparent reason. This left me stranded after dark in Baltimore City. I was able to get a jump start to get home but the car would not start even after the battery was placed on a charger. There are numerous internet news items describing similar stories. I contacted the dealer who refused to assist and therefore replaced the battery myself. There was no warning that this would happen.

Battery intermittently drains and goes completely dead. At times I have heard what sounds to be an electric motor running at night when the car is off in the garage without the key in the ignition. The dealer has changed the battery but that did not fix the problem.

Battery intermittently goes dead without warning. When the car is off at times one can hear what sounds like an electric motor running. One time the tail gate was found up and the battery was dead. No one can remember leaving the gate up.

On multiple occasions,, the battery has gone completely dead after the car was parked for as little as three weeks in a heated garage. Subaru replaced the original battery with one having a larger capacity but even that went dead after not being driven for three weeks. In addition, after the battery is recharged, the front passenger window cannot be rolled down using the driver side window control (the passenger window must be rolled down using the passenger side control before the driver side control will work). Subaru is aware of the battery drain problem because the dealership recommended the purchase of an auxiliary battery to carry in the car in case of a dead battery.

Rear view camera freezes up. When in Reverse it stays frozen. Rendering the rear safety camera inoperative. Definitely a safety issue. Has been to dealer multiple times to repair this problem. And it still is happening.

The Battery dies within a year of being installed, this has left me stranded waiting for help on multiple occasions as well as made me late for work. I have had the battery replaced 2 times within 3 years of ownership.

Repeated battery failures. Two battery replacements and battery still is not holding a charge. First battery replacement at 17,120 miles - 5/30/2020 Second battery replacement on 21,300 miles - 2/20/2021 Latest, battery died on 8/22/2021 with about 24,000 miles. Had to be jumped.

ON 2 OCCASIONS MY BATTERY WENT DEAD FOR NO APPARENT REASON . I brought it in to the dealership. The dealership suggested that i leave it for a complete diagnostic evaluation. they came back saying nothing was wrong. someone sent me an article about a man who is suing Subaru for the exact problem i had.

After filling the vehicle with gas, the vehicle was able to start but with only enough power to drive at 15-20 miles per hour. I drove directly to the Subaru dealer (at 15 miles per hour) where they diagnosed a "bad cell" in the battery. They sold me and installed a replacement battery which resolved the problem. The vehicle was 2 years old with 42,581 miles on it at the time. There were no warnings prior to this incident and the vehicle and faulty battery were not inspected by anyone other than the mechanics at the dealership.

Battery drained and died for no reason within 2 weeks of purchase.

Sunday,August 1, 2021, at 9:05am, I backed out of my garage and when I attempted to turn my car, the steering locked, the car was drifting backwards and I had no brakes. As a result the car kept drifting backwards , off the driveway into the woods, hitting a tree. Once stopped, I was able to start the car and drive it out of the woods. The entire driver’s side was sideswiped and mirror torn off. I was not injured, but could have been. I called insurance that day. On Monday, we contacted the Subaru dealership. The local police were notified and documented the report. The insurance adjuster determined the car unsafe to drive and it was towed to the dealership August 4, 2021. There was no warning or indicated problem prior to the incident.

Battery is not keeping charge, unable to start vehicle even after daily driving. With an infant, we need something more reliable, being stranded is not an option. Vehicle has not been inspected, upon further review this is a constant problem with lawsuits requesting for a resolution against Subaru. Battery indicator light would turn on and lights would flash when able.

Battery randomly discharges to zero voltage. Passenger window randomly cannot be operated from drivers side. Sometime it can, sometimes not.

Battery corroded excessively so much so that when it was able to be removed the connector for the battery broke. Battery was replaced and the passenger window can't be operated from driver side, one touch driver window no longer works either.

OEM battery failed at ~17,800 miles.

To: Subaru Motors Consumer Reports NHtSA I, Richard McNitt, am the very unhappy owner of a 2018 Subaru Outback (4 cylinder “Touring” model with 33,900 miles), VIN 4S4 BSATCT J3362742. Primarily on the basis of “glowing” Consumer Reports Reviews I chose this model….sad to say this was an unfortunate choice. I list some of the troubles endured: • Shortly after delivery the “radio-GPS” failed, replacement was in short supply(!), Did without several weeks and the re-installation had a glitch. •We were informed that the radio would always “come on” when the car was started, My wife finds this very annoying, •We find the road noise to be excessive, especially at around 25 mph, •We were left sitting twice with a “dead” battery, once at the end of a two hour trip when the radio was on after for less than 15 minutes. ••But the worst situation was this…..My daughter, granddaughter,...
