Battery Dead problems of the 2018 Subaru Outback

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.

I have a fairly new oem Subaru battery in my 2018 Outback. It continues to drain unexpectedly. I know about the tailgate problem. Also, I turn everything electrical (that's possible) off in the car when it's garaged. The battery often fails to start the car when it's unused for a few days � even after previously driving long distances.

Twice in the past 12 months my Subaru Outback has left me stranded with a dead battery. The first time I drove to the grocery and the battery was dead after I finished shopping. Second time I drove to church and the battery was dead upon leaving.

Battery failed at 9,000 miles.

Dead battery issues - if doors or liftgate is open for even short amounts of time the battery goes dead. Have had to had it jumped 6 or 7 times since we bought it 3 years ago. That leads to issues with liftgate and passenger windows, requiring deal resets. Issue started at less than 10,000 miles.

Battery has gone dead twice, almost 3 times. The car was stationary.

Purchased a 2018 Subaru Outback 5/03/18. At 19,860 miles on 12/21/19 the battery died. I jumped it, got it to the dealership. They did whatever diagnostics on it, recharged it and had me pick it up. When I went to get it, it was dead in the dealership parking lot. They then put in new battery. I went back down to pick it up. On 3/15/21, only 13 months later, my new battery was once again dead. I had been in my driveway parked for a week or possibly less. I picked it up 3/17/21 after Subaru had to again replace the battery. Bottom line I was told by the dealership to carry jump cables because it will keep happening due to the electronics! it seems I can only upload 1 repair invoice so I uploaded the most recent battery replacement invoice. I have 2 others.

I purchased this 2018 Outback in late November of 2020 with 27000 miles on it. After only driving it about 1500 miles the battery suddenly died (March 2021). Aaa jumped it but said it was dead. I replaced it immediately (went 1 mile down the road) and the shop said that it was dead as well. No warning at all. Was working fine, parked at a store, ten minutes later went to start it and there was nothing. I spent $170 getting a new battery/installation.

The oem battery was failing to hold a charge and died one day after driving a short distance. Had to have a local tow service come and jumpstart the car. Took the car to the local dealer and they needed to charge the battery.

Car was purchased in June 2018. Peridically over the first two years of ownership the battery would die and the car would require a jump to start. Since the onset of the covid pandemic - with the car left unused (in a garage) for more extended periods - the battery dies frequently, each time requiring a jump to start. Now, if the car is not started at least once every 1-2 days the battery will be dead.

The battery keeps dying for no reason. Thr first time it occurred was in October 2020. We jump started the vehicle and drove it. It died again two days later. We replaced the battery with one from an auto parts store. Approximately 5 weeks later in December 2020 it did the same thing. We went to start it up and it wouldn't start. We jumped it and drove it for approximately 30 minutes. Went out the next day and it wouldn't start again. Took it to the dealership and they stated the problem was the battery so I paid for a replacement. Exactly a month later, January 2021, I went out to start the car and the battery is again dead. I will be taking it back in to the dealership this week.

Battery died 2 times within 3 months of purchase (bought used, Nov 2020) first time with light left on overnight and second time after not driving for less than 1 week.

This is the second time in two weeks that our vehicle has failed to start. A week ago it left us stranded at a walmart, and today in our driveway. . . There isn't any electrical device in the car that will energize. The car won't even respond to the vehicle key fob. We can't find any recalls on our vehicle. . . But we notice you have several complaints (401) with many being electrical issues � failures. This vehicle was stationary during both of the described issues. I think this time total battery failure has occurred. Please note there weren't any indicators warnings that the battery was going to fail. This vehicle is less than three years old, with just under 18,000 miles never driven anywhere in snow areas while deicers were in use. Will be contacting Subaru this am for assistance.

The electrical system of the car drains the battery after a few days of not using the car. The car was purchased brand new in July, 2018. The car has a battery problem from the beginning. First time when the battery died I charged it myself and I took the car to the dealership for inspection. At the dealership they couldt find any issue. Since that time the car's battery drained completely six times preventing the car from starting. If the battery was not connected to a battery tender it went completely dead after a few days. Last time when the battery drained it couldn't be charged with a charger and also the car couldn't be jumped. After investing in a new battery and installing it on the car the battery drained again completely after a few days when the car was parked in the garage and not used.

Battery died many times. Car is just under 3 years old, with 18,000 miles still under warranty. Dealer said the car must be left that they needed to test. The cca rating is 300 something. A friend in colorado has a 2019 forester with a cca of 620! very similar engine, both models are touring. Could it be that vehicles in less colder areas are fitted with inadequate battery cca so Subaru can save a few dollars? also the rab light came on while driving at highway speeds. How is that ok? the infotainment screen has frozen multiple times. When it did the volume of the radio could not be lowered. . I was parked when it happened, (radio was loud) then started driving and couldn't lower it. . Please note: these electrical issues occurred at different times . . . I have no idea if they're related.

Vehicle has 17,000 miles, battery has died at least 6 times. Battery has been found drained in the am after being parked in garage. Dealer replaced battery at 16,000 miles. Battery problem still exists. Subaru tries to explain problem by stating interior lights are left on or key was left to close to car. Tests show there was no parasitic drain on battery. Subaru does not want to fix or admit the problem.

Second occurrence of the problem in less than a week. Replaced original battery on 7/24/2020 (see complaint number 11341827). Battery drains for no reason, leaving battery dead and car inoperable. Car was stationary on driveway. Could not start it, so checked battery which was dead 0 volts.

My 2018 Subaru Outback has been having issues with the battery and the car not starting. It seemed to have stemmed from the liftgate working improperly and draining the battery. It happened about a year ago, but self-resolved after resetting liftgate and jump starting car. Recently, about two weeks ago, it started having issues with the liftgate and battery again and was left stuck at a shopping center parking lot until I was able to get roadside assistance with a jumpstart. I brought it to Subaru in fairfield, CA, where they diagnosed it as a liftgate issue that was draining the battery. They reset the liftgate and then charged the battery and sent me on my way. Today 6/6/2020, my car had difficulty starting again, took a few tries to start, though there were no issues with the liftgate. I brought it to Subaru fairfield, CA again, where they said there was a battery failure, I was out of warranty for a replacement, and would be charged for a new battery even though they said that they know that there is an issue with a number of recent Subaru owners with battery issues. Doing research online, it seems like it is a very common issue, leaving owners stranded randomly and needing a jump start, and that battery replacements are not fixing the problem, as the electrical draining issue is still there.

When I park my car in the garage on Thursday July 2nd and close the garage with no problem. On July 4th my wife open the garage and got a chair from her car Acura rdx and watch the fireworks on the drive way. Later on put the chair back in her Acura and close the garage. Sunday afternoon I had to go to the garage and get tools to fix the bathroom sink and saw the Subaru Outback hatchback open. I then found the subraru Outback battery dead and the hatchback all scratches. My wife only has her Acura car fob, the other subraru hanging on a closet door. My subraru key fob is in my work computer briefcase. Definitely nobody touch the subraru fobs. However, I only drive the subraru Outback to work ( vanpool meeting location) about 4 miles from my house and usually about 5 minutes one way. The car unable to startup after the incident.

Battery was dead in may 2020. Purchased new battery 5/28/2020. New battery was dead 6/4/2020. New battery had lasted only 7 days.

The vehicle's original battery died after only 30 months of use. I tried to start the car one morning, and it would not start. A new battery fixed the problem. This happened during a period when the car was driven for short trips only a couple of times a week, during the early part of the covid-19 pandemic shutdown. I am reporting this because of other reports of a possible electrical problem in Subarus that has caused batteries to fail earlier than they should have failed.

The car has 19065 miles and will not start because the battery is dead. The car will start when jump started following the manual procedures. However the battery immediately discharges when engine is turned off. When the battery is disconnected from the car the voltage is 12. 65 but when the battery is reconnected yo the car the voltage drops to 5. 75 indicating there is a load on the battery when the car is in the off mode. When running or driving the battery warning lite is not displayed.

The battery in my 2018 Subaru Outback has died 3 times in the past 6 months. The first time I was parked close to a local mechanic and after jumping and testing the battery he deemed it dead and replaced it. 2 months later, while parked and idling as I waited for my husband at an appointment, the car shut down and went dead. It would not restart, but after I waited a few minutes it restarted. A month ago as I was driving about an hour from home, all the dashboard lights went on and the safety (eyesight) system disabled. I took the car into the dealer the next day and also told them about the dead battery and asked them to check the electrical system for a drain. This morning (exactly one month since dealer service) the battery was dead again. After jumping it and starting the car I discovered that the rear liftgate will not work. I have tried from inside the car, outside using the button on the liftgate and remotely with the key fob, nothing. After a a quick internet search I see that this battery drain is a common complaint with this model/year and that Subaru just replaces the battery rather than address the underlying problem. This is not acceptable, I should not have to worry about whether my car will start every time I get in it.

Purchased this car in Feb 2018. Despite the pandemic of 2020, mileage is somewhat similar, driving trips are similar since getting the car. The battery has been dying over and over since earlier this year (Feb/March 2020) for no apparent reason. On many occasions, after sitting in the driveway for a few days, a week, a day - the battery would be dead. Brought it to Subaru and they told me some crap about not driving it for periods of time could cause this (a week?!). They tested my battery and said it was better than perfect. Now it's going back in to them because it is still happening and now they are claiming it's due to low mileage. They know more about this than they are leading on and are blaming the vehicle owners' driving habits instead of getting to the root of the problem.

I have replaced the battery twice and the battery is still dead if I don't drive the vehicle for more than 3 days. Obviously there is a parasitic drain. I don't have an options or accessories installed that did come with the vehicle when purchased.

The battery has died randomly over the last 2 years. We finally replaced it after being fed up with being stranded in different locations. Most recently, it died twice within a week. Both times I drove to work, parked and 2 hours later, the car had to be jumped to start. I took the car to Subaru and they wanted to charge me $250 to insert the same battery.

Battery on car just goes dead. Put 3rd battery in car before it was 3 years old. Several times, we noticed that rear hatch motor does not shut off - just keeps running. Then if you start car again & immediately turn it off - rear hatch motor stops running. Been to dealer multiple times & sent letter to Subaru customer advocacy dept - they refuse to acknowledge car has a problem. Offered to pay for extended life battery. First time it happened, car was parked in our garage overnight - having been loaded the previous night to leave early the next morning on vacation - car wouldn't start and battery couldn't even be recharged. One time backed car out of garage, turned it off, then when tried to start it 5 minutes later, battery was dead. We were able to recharge it, but subsequently took it to dealer where it failed the battery test and they replaced the battery. Vehicle deemed unreliable and unsafe to us, as you never know if it will start. Been to dealer several times about this issue and they are doing nothing to get to root cause of problem - just put another battery in car. Car has 25,000 miles and warranty expired on 2/24/2021. Attached are details from 2 dealer visits and letter to customer advocacy dept. First time battery failed, we replaced battery because it was impacting our vacation. We had expressed concerns about battery on 7/19 dealer visit, and battery then died on 10/19. Subaru refunded us the cost of the battery.

Battery dies prematurely, if vehicle is not driven for a few days, or if parked and rear hatch is opened and closed a few times. Dead battery left me stranded five times since 3/5/2019. Battery tested well at dealership three times, so was not replaced under warranty until it failed a draw test.

Battery failing to start car, received new battery from schomp Subaru summer 2019 after repeated jump starts, towed to dealership twice, continuing with same problem and today I am stuck at home waiting for my schumacher portable charger to recharge. I am araid to drive the car because I don't know when it will stop working. I was told it was because I didn't drive it enough. I leave the car idling.

Tthe battery has gone dead several times. The dealer replaced the battery one time under warranty. It now indicates a weakness in cranking power after the car sits without driving for a few days. It needs to be replaced with a new and more powerful battery.

2018 Subaru Outback: per dealer: original battery "bad" & replaced by dealer after it failed (unable to start & won't hold charge) after 10,500 miles at 9 mo. Battery also failed in our previously owned 2015 Outback after only 3 weeks, & in a 2015 Subaru legacy after 35 months. The 2018 Outback's touch screen (& back-up camera screen, etc) has also stopped working twice, at about 2 months (while backing out of the driveway) & again at 3 months, both times suddenly, the screen going black for a minute or longer, & then turning white for several minutes before resuming the normal screen configuration & appearance.

Parasitic battery drain - premature battery failure rendering vehicle inoperable. Vehicle can not sit or idle for less than day without battery fully discharging, requiring jump start or roadside assist. Battery has been replaced twice in less than 3 years and less than 10k miles on 2018 vehicle purchased new (through dealer-- under warranty) . Battery replacement has not cured defect, and vehicle continues to fail. Vehicle has not been in accident, and is used customarily.
