Battery keeps draining. I replaced the original battery 6 months ago and it just drained again.
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!!.
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.
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.
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.
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!!.
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.
Entertainment unit defects car battery fast drainage.
Battery draining issue. Jump starts required.
In past 3 years after not being driven for 3 days the car would not start. We had the battery charged and replaced twice . When I spoke to another Subaru owner I was informed of a lawsuit against Subaru concerning parasitic battery draw by the starlink system. I contacted Subaru of America and was told there was no recall but I am entitled to extended warranty on the t 16 dcm unit (a fuse for starlink). They said I would be responsible for any charges to fix the issue. When I called my local Subaru dealer they said I may have to pay for diagnostics even if it was the dcm fuse as the problem. I feel Subaru knew about this problem and should fix it without charge.
Battery is dying pre-emptively. Have gone through 2 batteries in one month.
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.
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.
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 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.
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.
The radio touch screen is defective. It does not respond to touches and does things on its own (ghost touches). Subaru and harman kardon are aware of the problem and even extended the warranty but unless your unit failed within the warranty window you're out of luck. The problem is this -- these units are now an integral part of vehicle functionality and a malfunctioning unit is a serious safety issue.
Battery failed and had to be replaced wheel bearing replacement.
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 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.
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 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.
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.
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.
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.
What component or system failed or malfunctioned, and is it available for inspection upon request? after about 1 year of procuring vehicle, the car battery would die about every 4-8 weeks. How was your safety or the safety of others put at risk? I travel often and could *never* rely on my car to start up properly. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, and also is in a civil law suit because of it. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? yes, although still not even remotely confident that they have truly identified the issue. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no warnings whatsoever. The battery would be fully charged one day and dead as dead can be the next. As noted above, it first started after about a year of having the vehicle, then started trouble shooting w/ the dealer for about the next 2 years over about 6 appointments.
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 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?.
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.
