My car started to have battery issues either last year or early this year. The battery issues are getting worse. At the very beginning, the battery died after a couple of days not driving; which was shocking because it is a fairly new car. Today the battery died just overnight; I was driving to work yesterday and we were about to drive to hershey park today:( there already have been several times of roadside service for the jump start when the millage was less than 20000. I was told by the dealer that the battery drains due to the electronic design. He suggested I drive the car everyday just to charge the battery. Really!?.

The battery in our car was dead after accidentally leaving the tailgate door open for about 3 hours. We didn't think that was enough to do it but jum started it and it was ok for a day but then wouldn't start regularly without leaving any doors open. We took it into Subaru and ultimately had the batter changed even though they told us it wasn't the battery. The battery was dead again today when we went to use it. We maybe left the tailgate open for 30 minutes a few days ago unloading groceries. That seems a little extreme. The vehicle was stationary in our driveway but it happened at a parking garage before too leaving me to need to get a ride.

The vehicle started beeping while it was off and sitting in the carport. Upon further inspection, the beeping was coming from the rear lift gate. We tried to unlock the car with the fob, but it would not unlock leading us to assume the battery was dead. We used the key hidden inside the fob and opened the car door and attempted to start the car, but it did not work. We were able to jump the car off and the beeping stopped. We took the car to the Subaru dealership where they inspected the battery and replaced it with a new one because the current one was "bad". Of note, the battery had just been replaced 2 months prior during a routine inspection that revealed another "bad" battery. I have owned the car since oct 2019 and this is the third battery that I have had in the car.

I started having issues when trying to turn the car on - it would appear the battery was dead despite no reason for it to be. This happened multiple times for a week. I brought my car in to see what the issue was and the auto repair shop said the battery was bad and needs to be replaced. The vehicle is barely a year old with only 11,000 miles on it.

The car battery keeps dying. The first battery died a little after a year. The second car battery died two months and few days later. I drive the car a few times a week. I've never had a different car die under the same driving conditions. When I jump start the car after the battery dies, the electronics in the car do not function properly. When I quickly steer the steering wheel, eyesight, power steering, and other various electronics rapidly turn on and off. This seems to indicate that the battery cannot be charged, and sufficiently power the vehicle, while the vehicle is running and causes unsafe driving conditions. After receiving the new battery, these issues were mitigated until the new battery died two months later and the same behavior is happening again. The first time I went to the dealership about this issue, they said the battery was faulty and replaced it with a new battery under warranty. I'm still waiting for my next service appointment to resolve this issue.

Battery goes dead after sitting a few days. It has died twice in 2 weeks. Have to carry a emergency jump system dealer replaced battery.

Multiple electrical issues. Now on second battery. Vehicle in driveway, tailgate opened for 30-45 minutes and battery died. Vehicle in driveway with radio on for 1 hour, battery died. Vehicle in driveway, not driven for 12 days and battery died. Each time battery died, unable to easily jumpstart. Each time battery died, tailgate unable to open even manually.

The battery fails and cannot be recharged, it drains immediately. Also the airbags no longer work. We have had the car jump started by. A tow truck and then charged the battery at home with our own charger and it still dies immediately.

Tried starting my car on March 5 and would not start. Tried to jump start but it did not work. Had it towed to the dealer and was told battery is dead. Dealer could not explain why battery died. Dealer replaced old battery with the same oem battery. This is a temporary fix and I told them I'm not confident this will not happen again.

Premature battery drain. Ive replaced the battery in my Ascent 3 times in the past 2 years I've had the vehicle. First instance occured when taligate hadnt closed all the way and drianed battery. Second instance car doors were open for approx 2 hours to clean and detail my car when battery died. Third instance was listening to music in the car for 40 min while waiting for husband to go to store and I waited in the car and batter died yet again.

I have had many many times that the battery on my new car has died if it has not been driven daily. I had the shop test the battery the last time it was in and they said there was no problem. The car battery has died at least 5 times since I purchased the vehicle new in July 2019. I have been made aware of a class action lawsuit regarding this issue. My car has died again this week. I am working from home and with the massive snow, I did not drive the car for a few days and now it is dead.

My car is 1. 5 years old and the battery died in me and left me stranded. Car started after being jumped. I used my trickle charger and it is telling me that battery is bad. Car electrical system was acting strange and not turning off all systems when car was turned off. This probably drained battery.

My battery has failed multiple times. The first time after driving for a short distance and parking and using accessory mode x 10 min. The second after sitting in my driveway for two days. At that point, I was told that there was a "faulty cell" in my original batter and the battery was replaced. The third time after having the rear gate and doors open for approximately 30 min to vacuum the car. The forth after driving a short distance to the grocery store and waiting with the car in accessory mode for approximately 10 minutes for my groceries to be brought out. This last time it was below freezing outdoors. I was fortunate enough to be near a store and not have my two young children in the car. I had chosen to do grocery pick-up to reduce my pandemic risk, however, I had to wait inside the store for someone to come and jump my battery.

Went to bjs to get food battery died 18k.

Vehicle will not start because battery is dead and requires a jump. This is the third time it has occurred. We have had to call starlink to come and jump the battery which resolved the issue on 1/25/21, 12/29/20 and 6/20/20. The vehicle was purchased new in may 2020. It is kept in a garage when not in use.

My 2020 Subaru Ascent touring has 8500 miles on it. I purchased it in November 2019. The battery has "died" about 5-6 times since I purchased the vehicle. I drive my Subaru usually on short trips and one long trip per year. I have reported the dead battery issue several times to my local Subaru dealer and they always say nothing is wrong with my battery. I could drive my car on a short trip one day and then the next day when I try to start my car, the battery is dead.

At 2 years and 5 months old (55k miles, mostly highway driven) the battery dies and I was stranded when I had stopped and parked. Would not start anymore. Had to jump start car and drive to dealership. Subaru dealership (gillman Subaru southwest, houston, TX) did a load test and determined battery is dead. Would not replace battery. Wanted to charge $500 to replace battery!! went to auto zone and had it replaced and installed for under $200!.

Battery has died at least 3-4 times since purchasing the car. Also ongoing issues with the radio- radio has stopped working completely before two instances when the radio died. Amplifier has been changed in car and serviced multiple times. Once while driving, the car died while driving it and steering locked.

The battery does not stay charged nor can I get it to charge above 80%. I store her in a garage. In the last two weeks, the battery has been dead (and required a jump) 3 times in 2 weeks. I get up and go into the garage to start the vehicle and the battery is just dead. I took it to the dealer to test the battery and was told that there is nothing wrong with it. My conclusion is that it must be an electrical problem.

The vehicle only has 9000 miles. The battery just died and it is not holding a charge.

My wife parked the vehicle and when she went to start it the battery was dead at only 1667 miles.

Has a defective electrical system causing the battery to drain prematurely. Just had the new Subaru battery tested and charged at advance auto parts and it was brought up to almost a full charge. After 4 days of short trips, battery is dead again.

At only 17. 6k miles, the battery in my 2019 Subaru Ascent was completely drained overnight, for no logical reason. I called Subaru roadside assistance to give me a jump and I let it run for 33 minutes then took it for a 10 min drive. The battery was dead again the next morning. Vehicle was stationary overnight and until the 10 min drive. During this time the tailgate would persistently beep, trying to open.

Had only 5800 miles and cost cell phone worksheet come through speaker then couldn't open tailgate. Next day battery was dead after getting on car and dash lights flashed like a xmas tree.

I have about 7000 miles and my battery has been dieing and needing a jump start. I took it to the dealer in April and no issues were reported by the dealership. The problem happened 2 days back and again I had to jumpstart and drove the vehicle for 5 minutes. But the car would again not start 30 minutes later and needed yet another jump start. I have a follow up appointment with the dealer and the battery problem seems to be common in many Subarus as assessed by online forums.

Battery dead even though car has been in garage and driven at least 2-3x a week. Happened a few times since the first incident happened in oct 2020, and then subsequently multiple times where we need it to be jumped start. Eventually took to dealership for diagnosis and they had to replace the battery in Mar 2021.

2 episodes of disabled 2020 Subaru Ascent touring in 4 months after purchasing it new. Currently only has 3600 miles on it. 1. Car would not start from stationary position because both my electronic key fobs were in the car at the same time. Towed to dealer. They found my 'missing' key fob. 2. Battery died while stationary, waiting at vet 25 min. , listening to radio while car was otherwise 'off'. Only it did not die a clean death but continued a zombie existence: a/c came on and off at full speed, arbitrarily; actually could not shut down the car kept acting electrically crazy with various lights on dash coming on and off; 3. Could work the power windows while the battery was 'dead' , windows would go down but only came partway back up; for some 40 minutes we heard a beep in a morse code sort of irregular manner from interior rear aspect of car; dash would click from time arbitrarily, sounded like the click heard during cruise control when approaching a vehicle ahead, the 'adaptable' feature, or perhaps the click heard when switching from high beam to low beam lights. I don't feel I can rely on this car not dying. Very upset, and very disappointing.

Battery frequently dies overnight. I'll get in the car the next morning to take my kids to school and go to work and battery is dead for no reason. No lights left on or doors open. Vehicle is stationary. This has happened at least 6 times over 2 years.

Turned car off and electric cooling fan continued to run. Didnt think much off it, maybe cool down phase. Next time went to start car, battery dead. When charging on rapid charger, when volts got high enough fan ran again. Then was able to start. Charged battery. Sat for few days and dead again. Technician at Subaru says battery is charged and fine after my wife drove 2 hours to nearest dealership to inspect, after jumping it to go get warranty covered battery. Intent search shows others having issues with batteries. About had it with Subaru and the issues. 35k for a "reliable " car. I could understand if this was one off but it's not.

Battery dies regularly - dealer has replaced the battery three times already. No lights are on, no clear reason why the battery slowly and consistently drains over time. The vehicle was stationary, but child and pet have been locked inside, and it has happened in remote locations. Also, with electrical parking brake, it can't be released for towing when the battery dies. Stranded in the woods with a kid trapped in the car and no means of jumping it is very dangerous.

The battery died when my Ascent kept beeping 3 times after I closed the trunk with the remote. It beeps 3 times every 20 seconds in an hour. The battery died.

We bought a used 2019 Subaru Ascent touring (CA. 18,000 miles) in July of this year. The dealership replaced the battery when we bought it. Since then, this new battery has died five times on us, the first time on September 4 2020 and most recently on November 28. It has always died while the vehicle was stationary. After it died the third time on November 22, we brought it into the local Subaru dealership. They held the car for two nights and were unable find anything wrong with it. It is currently at the dealership again.

Battery has died twice within the first 12,000 miles without warning.

My 2020 Subaru Ascent has had a dead battery on more than 3 times, just in the last 2 months. When I went to the dealer on 2 different occasions, they told me that my battery was fine and that if you leave the dome lights, or radio on while the car is stopped, the battery will go dead, even though my car is less than a year old and has just 12000 miles. The first time they said if the lights are left on auto, that will drain the battery. They also told me today when I took it to the dealer,that this happens all the time with the Ascent.
