Subaru Battery Drain Settlement Announced. Insufficient Battery Capacity Failed To Support Vehicle Components

Subaru Battery Drain Settlement Announced. Insufficient Battery Capacity Failed To Support Vehicle Components

Last Updated on June 15, 2023

Is your Subaru’s battery dying prematurely and randomly? If so, you’re not alone. Many Subaru owners have experienced the same issue. This class action settlement is designed to help Subaru vehicle owners affected by the premature battery drain defect. If own a Subaru vehicle affected by this defect, you may be eligible for compensation.

While Subaru hasn’t admitted to any wrongdoing, the class action settlement has revealed that the vehicles components required more power than the battery was able to provide. Simply put, the OEM Subaru battery did not have the capacity to support the vehicle’s electrical components. As a result, Subaru owners experienced random and sudden premature dead batteries.

If you own a 2015-2020 Outback, 2015-2020 Forester, 2015-2020 Legacy, 2015-2020 WRX and 2019-2020 Ascent vehicle, you may be eligible to receive an extended battery warranty and cash reimbursements.

Subaru Battery Drain Problems

According to the class action, the electrical system in these Subaru vehicles are subject to a continuous parasitic drain. Allegedly, the battery drain problems stem from the vehicles Controller Area Network (CAN) system which fails to enter sleep mode when the vehicle is turned off.

The CAN system is designed to let components like electronic units, microcontrollers, devices, sensors and actuators communicate and work together without a host computer.

However, a defect in the vehicle results in the CAN system drawing significant “dark current” (parasitic battery draw) even when the vehicle is turned off and not being operated.

Further investigation showed that the batteries in these Subaru vehicles just simply weren’t designed to be continually drained down to low volumes of power. Thus, the parasitic draw reduces the battery’s total charge and its lifespan significantly shortened.

As a result, the battery defect leaves vehicle owners stranded requiring a jump start or battery replacement – far more often than expected.

While Subaru hasn’t admitted any wrongdoing for the defects in the vehicles they designed and manufactured, they have agreed to a settlement.

    We own a 2019 Outback purchased new from a Subaru dealer. Car has 28k miles, and has had battery replaced 4 times. Several of these situations put us in particularly critical situations. Solutions from both the dealer and Subaru America have ranged from ineffective to dismissive to non-sensical. Over the past years we have purchased 6 Subaru cars. However because of both dealer and national organisation disinterest in solving the continuing problem, we will never purchase from Subaru again.

      Perfect example of a manufacturer ignoring a good customer. Thanks for adding your voice to this settlement.

    My 2017 Outback had three battery replacements in the first year of use. Another replacement just before the warranty ran out. Last October that battery began losing it’s charge. Called the dealership to have the battery changed under the extended warranty but was told for weeks that they had no batteries and could not give me an appointment. Found a dealership 150 miles away that took a booking for battery replacement mid November. A few days before the appointment it was cancelled because no batteries were available. A month later the battery died for good in my garage. Still no batteries available at Subaru. Had AAA come out and change the battery because the car was not drivable otherwise. I was denied reimbursement for the $200 new battery for “reasons”. I will never own another Subaru.

      We have owned three OutbackS. A month ago we had the same battery drain issue with 2017 Outback. DCM chip needs replacement and Subaru is out of these indefinitely, plus out of class settlement deadline last month. The only fix is to unplug battery every night so it does not drain power. Subaru of America not helpful at all providing a solution. In addition the car needed registration renewed but could not pass inspection due to car info being erased with battery connection lost nightly. No guarantees what will happen even after chip replaced.
      We now have peace of mind…with a new CRV Honda Hybrid.

    So Subaru, known for reliability and safety, has a reliability design flaw that randomly kills the battery — do they realize how many customers they are going to lose over this? I am one of them. My Legacy dies if not started every week. Replacing the battery is not a sustainable solution.

    My daughter’s Forester has the same problem. Subaru gave us the finger. The legal system failed us. You should be telling people to never buy a Subaru.

    Just bot a 2023 Subaru Legacy. They replaced my battery after the first week of ownership when it was dead on Sunday. Today is Friday and the systems had a hard time starting up this morning, I called to let them know. Sounds like this is going to be a continuing problem uggh!!

      Sorry to hear Beth. Also keep a watch for windshield cracks:
      Previous models experienced this, and this problem may trickle into early 2023 models.

    Just bought my 2019 outback
    3 weeks later car is completely dead in my driveway
    Dealership has me in a loaner
    They’ve offered to replace the DCM that drains the battery vs buy vehicle back
    Ugh!!!! Although my loaner is a 2023 outback and I’m headed out tomorrow On vacation!!!

    I have only had one dead battery in my 2015 Forester. Of course I was camping at the time at a Washington State Park called “Cape Disappointment.” I had only had the car for a couple of months.

    Subaru replaced the battery, no questions asked. It has worked fine ever sense.

    I’m going to have to sell my 2019 outback, which I have otherwise loved. And now take out a car note that I shouldn’t have to be doing so soon. I will never buy another Subaru. What a disappointment.

    I have a 2019 Crosstrek that began losing battery power in December 2022. I replaced the battery, and then one moth later, the problem returned. Is the Crosstrek not eligible?

      Rebecca, the vehicles in the settlement have a similar and high incident rate of battery failure. Other Subaru models – like the Crosstrek were not within that same category. Hope this helps clarify the settlement details. Here is a little more info on the why your car wasn’t included: Why Wasn’t My Car Included In The Class Action Settlement?

    What good does it do in the long run if all I get is reimbursed for a new battery? Does the parasitic battery drain just magically go away with a new battery? No, it does not. I have been through 2 batteries on my 2017 Outback. I have been lucky enough that my Outback was in the garage when the batteries failed. Thank goodness for AAA as I live over 50 miles from the closest Subaru Service Center. What does it cost to resolve the problem? (Assuming that there is a resolution.)

      The 2017 Legacy from time I purchased it new always cranked slowly. I recognized early on that the factory battery was a to small piece of 🤬 and when I replaced it did some modifications to put in a battery that has almost double the cca “cold cranking amps”. It’s the maximum size that will fit in the battery box and you have to remove a few battery cable keepers to get the cables to reach. Purchased the battery at Costco. This helps greatly but when the CAN system randomly fails you can still end up with a dead battery. At least you don’t have to constantly hear that slow starter cranking sound that takes me back to the 1970’s and Chrysler’s starters whining.

    My girlfriend’s 2023 Legacy is doing the same thing so it hasn’t been fixed.

      Can anyone tell me if Subaru is replacing the bad ABS sensor that is causing the drain? It sounds like they are just giving stronger batteries to alleviate the problem. If that is the case, then why is the dealer asking for $2,000 for me to replace the defective sensor?

    Thanks for this article. Isn’t there a way to stop this parasitic draw in these vehicles? Can this CAN system be fixed? Are owners of these vehicles just supposed keep getting new batteries?

    I have battery issues. I see there are several things you can do. What is the best option? Tired of dead battery! Was told to leave keys away from vehicle. Seriously? Does not work!
