Outback Not Sure 2.5L

  • Automatic transmission
  • 64,000 miles


After driving the car for roughly 3 weeks fairly regular (every day or 2 days), the car did not start again. I called AAA again and they checked the battery capacity. They charged it and I took it back to the dealer.

The dealer could not find anything wrong even after keeping it for a few days. They also found the battery looked OK but recommended replacing it to eliminate it as a source of the issue.

I replaced the battery.

Outback Not Sure 2.5L

  • Automatic transmission
  • 63,430 miles

My car did not start and I called AAA. They found that the battery was dead and charged it. Upon charging the battery started up right away.

I took it to the dealer to check it out since the battery was only about 18 month old.

The dealer checked the battery and found it was charging fine. They suggested a light might have been left on and even though it was just over night it should be fine.

They did not think I needed to replace the battery.

Outback Limited 3.6L V6

  • Automatic transmission
  • 100,000 miles

I have taken the car into the Fairfield CA Subaru Dealership and they stated they gave me a free new battery, they had not because the newer battery I installed (which went dead) was still in the car. I have the paperwork to prove they did not change the battery. Then they stated they charged up my battery and all was good. The car has had to be jumped 3x now and the battery is only 6-8 months old. This is the third battery since I have owned the car. Subaru dealership never told me there was a technical bulletin on the issue and not sure they did the upgrade.

I'm a woman and now can not trust that my car will start when I go to it after shopping etc... or worse, at night out in the public. Then to find out from another friend who has an Outback that she has had battery problems with her 2016 Outback and when I googled battery problems with Subaru Outbacks, I find there is / was a class action lawsuit against Subaru...

Why are they not investigating this more and fixing the electrical problem/draw from the battery? I despise dishonesty... very disappointed.

Outback Premium 2.5L H4

  • CVT transmission
  • 58,800 miles


The Subaru was purchased new. After three years, the battery was showing signs of weakness. I put a maintenance charger on it to keep it charged. When I complained to the dealer, they told me the battery and charging system was good.

The battery started dying regularly after short trips before it was four years old. Get out the charger again and again. Good for awhile. Then my spouse calls me at work late at night 25 miles away in town. The battery is dead. Drove there to jump start it, got it started.

Took it back to the dealer. NOW there was a problem with the battery. So they happily charged me $221 to put in a "better" 30-month free replacement battery. Never had a battery go bad in that short of time. It was babied.

Now I keep a desulfating maintenance charger on it 24/7 when not driving it. Yes, a pain in the ass in the time it takes and the expense, but we can not afford another dead battery far away. Never had this problem with any other car in more than 50 years of car owenership.

Outback Premium 2.5L

  • CVT transmission
  • 25,000 miles

Drove the car till yesterday evening around 6 PM with no problems at all. Never a starting trouble too (like having to try twice or anything like that).

Did NOT leave any lights on. Car was locked properly (and does not have fob).

Today morning, the dashboard lights all came up, but the battery light was on. Thought may have left some light on. Checked everything, nothing.

Jump started the car with a portable battery pack. Was expecting the battery to charge after 30 mins. But even after driving for 45 mins, the car did not start later.

Taking it to workshop tomorrow.

Update from Oct 8, 2018: Jim Pattison Subaru Coquitlam, BC quoted me CA$259 to replace the battery with 3 years warranty!

The battery (group 25) is one of the rare ones. BCAA (AAA) said they don't carry it. Was searching for replacement battery for 3 days.

Finally found it (with higher CCA) at Edmonds Batteries in Surrey, BC. With taxes and installation they charged CA$156. Also 3 years full replacement warranty + another 3 years pro rated.

Outback Limited 2.5i

  • CVT transmission
  • 53,450 miles


I’ve never personally owned a new vehicle where the battery failed in less than 3 years. The OEM battery in the vehicle was manufactured by Johnson Controls, JIS Type: 55D23R, BCI Group: 25, CCA: 356.

The replacement battery, from Interstate, has a CCA of 550 and is a rated 600 battery.

The old battery tested bad with the recommendation to “replace” by two separate facilities where I had it checked out. In other words, the battery was working one day and, the next, not only failed and required a jumper cable to start but also tested bad.

One would think the OEM battery should last a bit longer than 34 months. The car is garaged and weather in the Northwest is hardly what I’d call “cold” most of the year.

Jan 192018


  • Automatic transmission
  • 30,000 miles

Car was parked in a heated garage with key off and removed. Suspect the parasitic draw caused by computer memory (ecm,dcm and radio) to exceed acceptable limits. Battery was drained down too low for my charger detect any voltage at all and could not be charged. Local Subaru dealer sold a new direct replacement and the car is being watched closely for further error.

Outback Limited 3.3L V6

  • Automatic transmission
  • 4,000 miles

Just purchased my first Subaru - - a new Outback Limited March 2015. First winter when the outside temperature dropped to freezing and below my Outback would not start. On one occasion I left inside vanity light on so this one time it was my fault. Thereafter, I was very careful to never leave lights on yet, the car still would not start on several occasions when the temps dropped to freezing. I took the car to the dealership where I purchased the car and they found nothing wrong. They told me I was not starting and driving my car enough and advised me to start car and drive it more often. My 20 year old Toyota Camry NEVER had this problem and I drove it the same short trips to store and around town. When I told the dealership this I was told to just take the long way back home from the store!!!!!! Following year I got a recall notice that addressed the problem. Three relays were were replaced. The description of the recall stated "Under certain extreme cold weather conditions, after the engine is shut off, ice crystals may form inside the relays which may temporary prevent you from re-starting the vehicle". After the relays were replaced per the recall I had no more problems starting the Outback the following severe winter.
