1 Electrical System problem

Failure Date: 09/17/2025

The clock spring (steering roll connector) component has failed, confirmed by the resulting complete loss of the horn function. Safety hazard: the component failure has resulted in the loss of the electrical connection to the driver's airbag system, rendering the primary airbag inoperable. This creates an unreasonable, life-threatening risk in the event of a collision. The problem has been diagnosed based on common failure patterns for this vehicle platform and confirmed via manufacturer correspondence. The problem first occurred on or about [input approximate date] with the simultaneous failure of the horn and subsequent inoperability of the driver's airbag. The manufacturer, Subaru of America (soa case #251013-1700910), was contacted and acknowledged the concern but refused to cover the repair under a goodwill adjustment, citing an expired warranty, despite the component's direct link to the critical airbag safety system.

2 Electrical System problem

Failure Date: 07/01/2025

Car unable to restart after sitting for several days. Battery and charging system test good after incident.

3 Electrical System problem

Failure Date: 03/10/2025

The infotainment unit has failed leading to awful disruptions. The unit will push its own buttons, change volume, make phone calls, etc without any human input. It’s an ongoing problem and even happens when the radio is turned off.

4 Electrical System problem

Failure Date: 02/18/2025

Yesterday, my car would not start due to a dead battery. This happened last week, as well. Both times, my husband used a battery charger to enable me to start my car. I have had this issue multiple times in the past, as well, and previously replaced the battery in 2022. I am also aware of a previous class action lawsuit, and several customer complaints about parasitic drain and poor battery performance in the 2015 Subaru Outbacks. Continuing to replace the battery is not only costly and bad for the environment, it doesn't solve the problem. There is some flaw in the electrical design of this car and Subaru needs to address the root cause. I am very concerned that I am going to be stranded somewhere in unsafe conditions, or not have my car available to me when I need to get to a critical appointment or respond to an emergency. This is unacceptable.

5 Electrical System problem

Failure Date: 01/11/2025

Battery fails repeatedly even after several battery replacements and dealer fixing the software at a hefty cost, presumable to make sure the battery is charging. My insurance company (state farm) dropped my roadside assistance coverage after repeated requests to get help to start the car. I continuously dread and fear that the car will not start after a drive to the grocery store. I dear not think about using the car to take a trip away from home. I bought jump starters and now take one with me every time I consider driving this car. God forbid it drains outs before I get back to the house to recharge it, which has happened and ended up bigging a stranger to jump start my car. It is a shame that this reputable company can sell a car that has this problem, that could be easily fixed which seems to be not a problem for other manufacturers.

6 Electrical System problem

Failure Date: 11/04/2024

The clock spring that controls the steering wheel, horn and other electrical accessories doesn’t work. This put my life and family’s lives at risk. This is a known issue for Subarus 2015-2019. There’s multiple videos online, I have spoken to multiple owners personally that have encountered the same issue. I spoke to the Subaru dealer and they said due to no recall has been issued for the VIN number of my vehicle they can’t replace it and it cost about $1,000 dls. We need the NHTSA to step in and ask Subaru to issue a recall to start replacing the defective units at no cost to the owner.

7 Electrical System problem

Failure Date: 09/02/2024

Been having issues with my Subaru Outback dying for years now. I’ve gone through 5 battery’s the last 6 years. No amount of driving seems to fix the issue, the replacement batteries only work for so long until it gets cold or I don’t drive my car for a week and suddenly it dies. I believe there is a parasitic drain somewhere, I can’t figure out what. I have nothing obstructing the hatch locking mechanism, I turn all my lights off and air system off before turn turning the car off. It’s becoming a serious issue, I have to jump my car almost everyday or every other day and am driving for over 40 minutes a day. Subaru has been unhelpful and I’m now not trusting of their help.

8 Electrical System problem

Failure Date: 03/13/2024

Ignition inhibitor switch causing car to stay in neutral, fried the starter and battery 8 months after getting a brand new transmission under Subaru warrenty.

9 Electrical System problem

Failure Date: 06/26/2023

There's a problem in a part called (clock spring/roll connector) that is responsible for the horn on steering wheel. It affects almost all Subaru models, like Outback, forester, legacy. . . I've verified it in a mechanic shop, and after all the tests of fuses, horn, and everything. They say the problem is the clock spring, a part that goes after the air bag and costs around $130 plus service ($150 minimum) to change. Then I research on internet and found out it's a very common problem with a lot of videos on youtube of people having the same issue and a lot of comments there of more people complaining about it that it should have a recall cause it's a security part. I couldn't use my horn when another driver almost hit me, that's how I figured out that my horn died. Those are just some of the videos with this related problem. There's a lot more on youtube and a lot of posts on internet forums as well: https://youtu. Be/e73ao9zrcum https://youtu. Be/vdxvafmq6qg https://youtu. Be/plbtvx2wzww https://youtu.

10 Electrical System problem

Failure Date: 06/07/2023

#1. I replaced the battery in June of 2022 after all the dash warning lights came on. My eyesight safety feature was rendered in operative. After the battery was replaced, all the warning lights eventually went out. In July of 2023 the same scenario happened again. I returned to advance auto retailer and the store manager checked the battery. She replaced the battery with a new one of greater cold cranking amps. She was most knowledgeable and extraordinarily gracious. I asked her to check the alternator for proper function and was told it was functioning as it should. #2. On June 07, 2023, I took the automobile in for service: oil and filter change and brake pads and rotors on all four wheels. My Subaru had 68,482 miles on this date. The technician (who previously was employed by a local Subaru dealership) noticed that the engine was leaking oil and diagnosed the timing cover gasket was leaking oil. Oil leaking would contribute to the bad smells entering the passenger compartment. The gasket and three seals were replaced at a cost of $1329. 94 plus 8% tax. Online research reveals that Subaru"s boxer engine suffers chronic oil consumption and seal problems. Subaru of America relies on the consumer to eat any repairs rather than fix the problem that has been going on for years.

11 Electrical System problem

Failure Date: 01/10/2023

The horn in my car quit working about a month ago. I have checked the fuses and relay involved in the horn fiction. I have also tested the horns themselves and they are working. All signs point to the clock spring in the steering column being bad.

12 Electrical System problem

Failure Date: 11/07/2022

I am on my 3rd battery since may 2015 when the Outback was purchased in el cajon, California. There have been multiple instances when I prepare to venture out and am unable to as the result of a dead battery. In every instance there was not an obvious instigating factor such as a light inadvertently left on. This situation is extremely disruptive resulting in my belief that I have an unreliable vehicle that has caused me to miss appointments and meetings. There is also a significant monetary loss in that this is a known and well- publicized issue that will render me unable to recoup market value upon sale of the vehicle. '.

13 Electrical System problem

Failure Date: 08/15/2022

Replaced 2 new batteries in 6 months. Batteries went totally dead. Batteries wer replaced by independent shop. Dealer changed battery to a Subaru oem battery, checked system, said everything ok. Read about complaints about Subaru batteries going dead months apart. Want to find out if there is a defect in Subarus.

14 Electrical System problem

Failure Date: 07/07/2022

The battery has been in need of replacement at least every year if not twice a year since purchase. This has led to issues with the rear hatch and other fuses being blown.

15 Electrical System problem

Failure Date: 07/03/2022

On multiple occasions I have had the tailgate open and the light has drained the battery to the point that it needs a jump start or a battery charging to get it to start back up. On one occasion the tailgate was only left open for 30 minutes and the car would not start due to the battery being drained from it. The battery is in perfect condition as it would start fine any other time.

16 Electrical System problem

Failure Date: 06/20/2022

Battery repeatedly drains when vehicle not used. Have replaced multiple batteries. Alternator checked and functioning.

17 Electrical System problem

Failure Date: 06/20/2022

On multiple occasions the car battery was drained and required a jump to start. Battery replaced less than 5 months ago. Service technicians unable to identify problem with alternator or parasitic drain.

18 Electrical System problem

Failure Date: 06/13/2022

The electrical system failed to go into sleep mode after parking the car. The battery was totally drained by morning causing us to find someone to use jumper cables to juice it up again.

19 Electrical System problem

Failure Date: 06/01/2022

Inoperative horn. Traced to continuity failure in steering roll connector, part #83111al13. No indication of fault and no other apparent continuity failure in adjoining wire paths.

20 Electrical System problem

Failure Date: 05/11/2022

Repeated battery drain, causing premature failure of the battery. Frequent replacement of the battery and reduced reliability have increased the cost of ownership. It has occurred multiple times over the duration of ownership.

21 Electrical System problem

Failure Date: 04/24/2022

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.

22 Electrical System problem

Failure Date: 04/04/2022

On multiple occassions, I have been unable to start my Outback b/c the battery is dead. Note that I have not left any lights on, doors open etc. And, when I have taken my car in for routine services, the battery is deemed to be in proper working condition. In addition to being extremely inconvenient when I cannot use my car as needed, this is a safety issue. What if I was not in a safe location when my car wouldn't start? what if I needed to use my car to get a pet to urgent medical care? when I purchased my Outback, I was confident in the Subaru brand for reliability. However, it no longer consider my Outback, or Subaru as a brand, reliable when I can't count on my car starting when I need it to. The date I provided in the additional details of this form is just the latest incident. I purchased this car in 2015 and my battery has been drained more than 5 times.

23 Electrical System problem

Failure Date: 03/27/2022

Our 2015 Subaru Outback has had 4 batteries in 4 years. After some research, a parasitic battery drain issue is common with this year Outback and other Subaru models. Some sites call out the Subaru can network as the culprit. Whatever the case, we have had the car to Subaru who changed firmware ostensibly to provide more charging at lower rpm. After that software change was made the problem has apparently gotten worse. Now the car's battery will drain in 2 days of use (the current battery is 4 weeks old). There are numerous complaints about this on line and the common opinion is that Subaru is not addressing the issue.

24 Electrical System problem

Failure Date: 02/22/2022

There is some kind of electrical malfunction or drainage that the battery drains even when car is turned off. Replacement of new battery results in the same problem after a few days.

25 Electrical System problem

Failure Date: 02/09/2022

The car regularly drains the battery. We are the original owners and have had to purchase 3 car batteries thus far. The car does not provide any warning messages or report any issues. Every time the battery has been drained it happens without explanation, over a dozen times since we’ve owned the car. We’ve always had the batteries inspected, and they’ve been in good contention with life left in them, just drained, needing a recharge. Unfortunately, the car counties to drain the battery, leaving me stranded, including at night away from home. The details for the incident I will be providing below will be for the most recent, this morning.

26 Electrical System problem

Failure Date: 01/27/2022

Battery drain over night, dead battery in the morning. Alternator output normal, terminal post clean and battery will charge with external charger. Battery is less than 2 year old.

27 Electrical System problem

Failure Date: 01/05/2022

The battery has gone completely dead 3 times over 6 years since I purchased this car new. The battery dies, like clockwork, every 2 years. I have purchased 2 new replacement batteries so far on 5/16/2017 (mileage 25,895) and 2/5/2019 (mileage 40,017). The third instance just occurred 1/5/2021 and I have not yet had a chance to take the car to a shop to determine whether the current jump-started battery will reliably hold a charge. Clearly, there is a problem in the Subaru electical system causing a constant drain on their batteries. A quick internet search uncovers that this has been a common occurrence among many Subaru owners over several model years.

28 Electrical System problem

Failure Date: 01/04/2022

Battery repeatedly fails every 2 years since new vehicle purchased. New vehicle purchased in 2015, had to replace battery in 2017 and replaced again in 2019. It is now Jan 2022 and battery had insufficient charge to start car. I have now had to purchase a $110 battery charger to hopefully maintain the charge on my battery. There were no accessories left on or other unusual circumstances that would cause the battery to drain. The vehicle is driven regularly and kept in a garage. There appears to be an ongoing problem with the vehicle routinely prematurely draining the battery over time.

29 Electrical System problem

Failure Date: 01/04/2022

1st time battery died when car was not in use at least for three days, back in Jan 2022. Was replaced. On 10/11/22, after the car was not in use for 4 days, 8 month old battery was died, had to replace, again. Recently received a Subaru battery settlement letter of a design defect that cuase battery drain.

30 Electrical System problem

Failure Date: 12/21/2021

On four occasions over the past five months my car needed a jump start for no apparent reason. I had a new Subaru battery installed last July, and a check up at a Subaru dealer last month which found no problems with the battery or alternator. I recently read about a battery drainage problem that other owners of this model have been experiencing as well.

31 Electrical System problem

Failure Date: 11/07/2021

My 2015 Subaru Outback has continually experienced random battery drain. I have replaced the battery 3 times since purchasing the car from a dealership in 2017. In all cases, there was no advanced warning indicating that the battery was low, the car had been driven regularly with an average amount of mileage and no lights were left on nor was there extreme weather. Most recently (11/7/2021) the tailgate was up with the car off for 30-45 minutes. It was jump started, we made it home and the next morning it had zero power. That last battery was purchased in April of 2021. The car is regularly maintained by the dealer and/or a certified mechanic.

32 Electrical System problem

Failure Date: 10/02/2021

On multiple occasions the battery completely dies over night for no apparent reason and with no warning. Nothing that draws power was left on. This is a hazard as we can be stuck someplace with no way to start our car. The battery and alternator always check out as normal (by local mechanic), yet it keeps dying to the point that there are no dash lights, horn, emergency blinker or anything else functioning. Most recently I can't even jump start the Outback. Some design defect, (electronic/ computer) is causing the vehicles' battery to drain quickly which renders the car inoperable.

33 Electrical System problem

Failure Date: 09/27/2021

This car has repeatedly drained the battery when completely off. I have replaced the battery thinking it was a faulty battery, only to have this occur repeatedly with a new battery. I am certain the doors are shut, lights are off, car is off and locked and nothing I have left on is in anyway draining the battery. I have even experienced this when driving the car for an hour, parking it for 30 minutes and coming back to a dead battery. The battery drops to 5v and car won’t start. The battery does charge and holds 13. 5v. This is not an error with the battery as I have replaced the battery.

34 Electrical System problem

Failure Date: 09/15/2021

I have had to change my car battery three times in four years. A couple times it seemed like my battery went bad soon after having service on my car even though my battery tested okay and given a green symbol. The last date I had to replace the battery is below.

35 Electrical System problem

Failure Date: 09/02/2021

Bought 2016 model December 29, 2015. Battery consistently drains. It has had at least 3 replacement batteries in 5 years. Car has less than 46k miles on it. Had to get jump started twice within a two week period, with a battery from February of 2020. Battery issues 3/2018 26k miles 2/2020 37k miles 8/2021 45k miles 9/2021 45k miles.
