Outback Limited 2.5L

  • Automatic transmission
  • 23,000 miles

Third time this has happened this Spring. I'm about to go on another road trip and am anxious that this problem will recur when I'm on the road. I've hooked the battery up to a trickle charger hoping I can get it charged enough tomorrow to get it started.

This was the second time this Spring that the battery was dead when I tried to start the car. I was just beginning a road trip, and had to delay my start awaiting road service.

Very inconvenient! Nothing else to add at this time.

Outback Limited 2.5L

  • Automatic transmission
  • 17,452 miles

Second time I had to get the battery replaced. Constant draining is happening when weather drops below 30 degrees, causing battery to die.

Vehicle does not want to start when it reads 5.5 volts. It will die in another year and I will then start thinking of getting a different, more dependable one. No confidence in Subaru anymore.

Outback LDJ32 4 cyl Turbo

  • Automatic transmission
  • 12,000 miles

Living in Brooklyn, NY, I park my car in a public underground garage. I generally only use my car on weekends. Hence, it sits in the garage 5 or more days between uses. Beginning in February 2022, EVERY TIME I get my car, the BATTERY IS DEAD and requires a jump start. I have purchased a jump start battery that has worked every time thus far. BUT this is ridiculous to have to jump start a 18 month old car with 12,000 miles on it.

In over 50 years of car ownership, including my 2021 Ford Fusion, I could leave the car in the garage for weeks without the battery gong dead! My wife says we should sell this car and get a reliable vehicle. We have a second home on Cape Cod, and there we have to drive at least once a day. We have never experienced the problem there.

Outback UT 2.5L

Within 6 months of buying a new Subaru the battery goes dead. Fortunately it was parked in my garage and I had a battery charger, but the whole thing was still annoying.

Outback UT 2.5L

  • Automatic transmission
  • 4,868 miles

This is the second time this year (2021) that the battery in my 2020 Subaru died. No warning. Tried to start the car and nothing. The car was parked in my garage the second time, also, so I ran the battery charger overnight. Next day no charge, still dead. Did some internet searching and found this (carcomplaints.com) web page. I learned that the car's computer draws power from the battery even when it is not being driven. If you don't drive the car enough the battery goes dead.

My Subaru dealership service department recommended that if I'm going to leave the car parked for extended periods I should purchase a battery tender.

Why aren't prospective buyers informed that the car's computer system continuously draws energy from the battery and the car will need to be driven a certain number of miles per week to keep the battery charged? Why doesn't the car have a battery icon indicating charge level, like my laptop and cell phone, so I can tell when the battery is getting low? Why after paying $35,000+ for a car it has such an obvious flaw? The most important thing a consumer needs in a car is that it start reliably. I think Subaru should give me a battery tender for free and begin being honest to future buyers!

Battery drained and and then dead, a leaking battery within 3 days of owning a new vehicle. Such a poor quality control.

Outback Touring 2.4L

  • Automatic transmission
  • 10,000 miles

I have two 2020 Outback Touring model basically identical and purchased within 3 months of each other. One car has had the battery replaced once and the other twice. The one with a single replacement presently has about 5000 miles and the other about 10000. Each have required calling AAA to get a jump start and then taking to the dealer where I was told that the battery was dead. I knew so because it wouldn't charge on a charger.

This last time when I took the car in I said something was definitely wrong electrically. I was asked how much i drove the cars and was given the distinct impression that i was being told that I didn't drive it enough. Was told that there is a "70 Milliamp" drain per day on the battery for the computer etc that run in the background. If the car isn't driven well in excess of 10 miles per day then the drain out draws the charging generated by my short drives. I specifically asked if they would recommend that I put both cars on "trickle chargers" to try to avoid this and was told that would be a good idea.

So now I have a traditionally powered car that i need to plug in every night or risk finding that my battery is dead in the morning.

I bought a Subaru Outback 2020. I have had it less than 8 months and the battery died today while I was parked, motor off, listening to the radio. Had to call for roadside assistance from Subaru. Then found out that this is a known problem and Subaru FAILED to mention it when I purchased the car. I'm contacting the Washington State Attorney General to find out how to join or start another lawsuit. You should be able to listen to your radio for hours with the car turned off. In both my Ford (2016) and Dodge (1998) and Toyota (1982), I was able to listen at high volume for hours at a time.

The battery was so dead from a half hour radio that the roadside person had to use 2 of the jumper packs to get it started Totally wrong

Why is Subaru continuing to use crappy batteries? Doesn't make sense to build a good car and then use crappy parts.

Outback Touring XT Boxer

  • CVT transmission
  • 6,800 miles

Just about one year into driving my new top of the line 2020 Outback, the battery dies. It has become a daily issue and it's very unreliable. I’d say it has happened about 20 times in two months, and I needed to buy a jump starter to use the car. It was particularly tedious when my kayaks were on top and stabilizing robes were secured to the front bumper, constantly loosening and unhooking them to pop the hood.

The only time the battery works is if I’ve driven over thirty minutes and restart the car within around 4 to 6 hours. I’ve resorted to keeping all lights off manually but nothing has changed. Interesting problems with the touchscreen and sensors for the rear power gat and passenger seat crept up. When the car won’t start, it was impossible to turn off the touchscreen or electrical, so there was no way to stop the car from discharging further.

Outback Limited 2.4L

  • Automatic transmission
  • 850 miles

My car has 800 miles on it, mostly from driving it from Cape Cod to the Dealer in Hanover, MA. SomethIng is draining the battery, but no one knows what. They still think I’m doing something to cause it to drain, but I just don’t buy it. 4 times it’s gone dead, one time it locked me out; and off and on the hatch decides it doesn’t want to work.

I’ve had 4 loaners, spent $$ for a tow, paid for gas for 2 vehicles, missed a dentist appointment, which I was charged for and have been stranded and frustrated numerous times. This is a brand new 2020 Outback and I am at wits end. Though I like the car, it is making me hate it. 2 months old with constant headaches.

Outback 2.5L

  • CVT transmission
  • 9,700 miles

The battery on my Outback has required jumping two times in the past month. Both times it was not the result of lights left on or door open for an extended time. Now each time I start the car I hold my breath and hope it will start. I went out and purchased an expensive remote starter in case it happens again. This shouldn't be required for a new car!
