2015 SUBARU OUTBACK Complaints

While driving at highway speed and traveling over about 6 hours, the car simply shut off. We were traveling on the highway in the passing lane. Without warning the car began to slow down rapidly, no dash lights on, but the engine was off. We managed to cross two lanes of traffic without power assist and once on the shoulder and slowing down, the engine lights all came on. Once fully stopped, we turned the car off, waited a few seconds and restarted. We were then able to complete our trip without difficulty. This has happened twice. The dealer has done full diagnostics twice but has been unable to find the problem. We have heard that other year Subaru outbacks have been recalled for this problem but our year isn't included.

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.

I proudly purchased my 2015 Subaru Outback, new, in April 2015. I currently have less than 18,000 miles on it. During the time I have owned my Outback, I have had to replace the battery 5 times, through no fault of my own. Subaru USA and my Subaru dealership say that I do not drive it enough. B/S. I have done some research online and have found many other Subaru owners who are constantly having battery problems and dead batteries. I understand some have filed a Class Action Suit. The problem appears to be that the battery drains down on a regular basis. Now when I put my car in my garage at night, I turn the headlights off completely, the radio off, the A/C off, and I do not set my parking brake for fear all of the above will drain my battery overnight. I am even afraid to set my car alarm. I have had to call AAA each time the battery has gone COMPLETELY DEAD. They are tired of seeing me. Fortunately for me, each time the battery has died, I was at home and my car in the garage. I am a senior citizen who is afraid my battery will die when I am not close to home. I purchased a Subaru because of its so-called reliability. I am tired of Subaru giving me the runaround and trying to make it look as though I am the problem. I, for the life of me, don't understand how this problem has been swept under the rug by Subaru for so LONG. When I chose the Outback, I had done my homework and went first to the LA Auto Show and the Outback, back then, appeared to be my dream car, which has turned into a nightmare for me. I had a Sienna for 15 years and only replaced the battery twice. PLEASE have your staff seriously look into this Subaru battery drainage problem. I am certainly not alone with this problem. Each time I go to start up my Outback, I have to hold my breath and keep my finger and toes crossed. Subaru USA has given me little or no answer to my problem. My dealership again tells me I have to drive more. The other Subaru owners must not drive enough!!!

On 8/25/21, during servicing, I was informed by the Subaru dealer who has always serviced my car that the driver's side head gasket was starting to go bad. The car had 54,108 miles on it and was 6 years and 5 months old. It had always been driven under normal conditions, on public roads, and 100% of the servicing had been performed by the Subaru dealer who sold me the car, which I bought new. In addition, I had never used the car for towing. Under the circumstances, it seemed indefensible that the head gasket should be going bad. It's a very expensive repair. The engine in question is the 3.6-liter 6-cylinder.

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

i will be purchasing my 4th battery, this seems to be an issue people are having with this 2015 outback. I maintain my car and garage store it and I continue to have dead batteries that need to be replaced, I am not leaving any interior or exterior lights on either.

I have to replace my battery 1-2 x year, possibly due to Parasitic draw. No lights have been left on, nor anything electrical when the car is shut off. Between batteries, I often have to jump my car to start it. I have been stranded places and I am in constant fear my car will not start.

My vehicle was purchased in September 2014. Approximately the night of March 9, 2017 my daughter apparently turned on a dome light, which remained on the rest of the night. My car had approximately 45k miles on it. The next day I attempted to start the car, nothing happened. The battery was so dead that even connecting to another vehicle for 20 minutes resulted in no change. I purchased a new battery on 3/10/2017. On 7/10/2021 with approximately 100,000 miles I was at an airport for pickup. I turned my car off upon arrival and waited for 30 - 40 minutes with the key in the ignition. I think that resulted in some lights remaining on. When I attempted to start my car to depart the airport it gave an indication of attempting to start but there was not enough power to facilitate the action. I needed to briefly connect my car to another for enough power to start the vehicle, which has run apparently fine since. Now I have to be vigilant to ensure no internal lights are on for more than a few minutes regardless of situation. Recently I read this article, https://www.motorbiscuit.com/dead-batteries-new-subaru-lawsuit-claims-least-five-models-defective-batteries/, which seems to be the situation I am in. It seems that two batteries in a period of 7 years and approximately 102,000 miles seems a bit excessive. A non-technical analysis leads me to think either Subaru is not putting an adequate power supply in at least their Outbacks, maybe other models based on at least the linked article, or something is wrong with the electrical management system resulting in drains on the battery resulting in significantly shorter battery life than found on other vehicles, which results in additional cost to consumers to replace batteries assuming they die at a convenient time and other costs are not incurred.

Bought this car used with low miles in 2019 from a Subaru dealership. We have had intermittent issues dating back to late 2019, where returning to the car find that the battery is dead when we went to start it. It usually happens when the vehicle was left for 4 hours or more, although not always. After reading several reports of the same issue, we are going to try a new, larger battery.

Car stalled, could not take out of gear; could not restart, could not set emergency brake, couldn’t turn key to restart. Finally a light came on that said hatch was open. Could not operate hatch from inside car. Jumped out hatch was closed. Opened and reclosed. Car started rolling. Ran to jump in and apply manual brake. I’m 85 years old. Very dangerous situation. Consumer stated AAA batteries failed several times. Vehicle was taken to a dealer for electrical failure.
