Battery Dead problems of the 2020 Subaru Ascent

Battery goes dead after a series of short trips. Happened once before. Dealer had the car for 3 days and could not reproduce the problem. Intermittent problem, stranding driver in potentially unsafe areas.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

Twice my 2020 Subaru Ascent's battery has been dead. It has been driven every day for at least 20-30 minutes. Nothing was left on, or open. There is obviously an elecrical issue draining the battery.

Battery died after three months. Charged then died completely. Towed to dealer for new battery. Had nothing to do with rail gate.

I have owned this vehicle since late may 2020, and I have approximately 2,000 miles on the odometer. On 7/25/20, I started the vehicle and there was no sound at all from the audio system - radio, navigation, voice commands, etc. Were all mute. I rebooted the radio by holding down the power button until it restarted, but this did not fix the issue, despite multiple reboots. I continued to drive my vehicle each day on 7/26 and 7/27, and the audio did not come back. On 7/29/20, I planned to call the dealer to report the issue. When I went to start my vehicle, which is kept in my garage, I discovered that the battery was completely dead. As soon as I tried to start the car, the tailgate began beeping, and then the headlamps flickered randomly for approximately one minute. There is no power at all in the vehicle, and I am unable to lock/unlock the car or open the tailgate, even manually. There were no doors left open, no lights left on - the battery simply died.

Battery has gone dead twice and had to be jumped.

V1. The battery died within 6 months 4 times :first time Aug. 21. 2020 , than Dec. 03. 2021 , Dec 24. 2021 and Jan. 04. 2021 2. The stereo system is not working properly sound cutting off frequently. 3. Break problem. Before 6 months the brakes had to be replaced and are still making grinding unusual noise. Even after multiple dealer service no improvement. Actual break action not consistent and not reliable save. 4. The ac system is not functioning properly - kicks in even when in heating mode. In using the remote start the ac kicks in immediately and changing the settings will not help. 5. The eyesight system is inconsistent with the warning lights coming on when there is no problem? instead of being a safety feature it is a dangerous problem feature. Because it is not reliable makes safe driving very difficult ? and we had considered this system as a plus when deciding on Subaru Ascent. 6. Problems with trunk opening ? sometimes will not work with key or from the inside ? has to be opened manually. 7. Oil level sensor had to be replaced. 8. The VIN number was listed to have a recall ? but when checking it out it showed 0 recalls. We consider this very strange. 9. After each visit to the dealer, we are told that everything is fine ? but one or two days later the same problems show up again. 10. Bluetooth system keeps deleting phones. 11. Rpm gauge not functioning. 12. Mpg indication never changes shows always same value ? even under completely different driving conditions. I am filing this claim for may daughter [xxx] because I bought the car at the time. Also the problems are ongoing since the date listed below information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

In Feb my car battery was dead in morning after sitting in garage turned off and no doors or lights on. I had it jumped and took it to the dealer and they tested battery and it was fine. The second time it happened a week later same scenario I took it in and they tested battery and said it was bad battery. So the dealer replaced it and it and it was fine. The third time now today it has happened again except this time my car was beeping at me like if the unlock key fob button had been hit but doing it every few seconds. So I went and found both key fobs and they weren't being depressed so I tried to unlock door myself with key fob and nothing happened and red light on fob blinked every time I touched it but I wouldn't hear anything happening with car so I tried to click tailgate button and nothing happened. So I then went to turn the car on and realized the battery was dead again. So we jumped it and let it run for twenty minutes and dealer wants us to take it back but they are saying they haven't heard if this issue when I search online it seems like this is a known issue.

We received our new vehicle on 04/28/2020 - the vehicle sat for several days (5-7) without being used. On 05/09/2020 the battery was dead and the vehicle had to be jumped to start it. Brought the car to the service department, no defects were found in the battery or charging system.

My car failed to start after it had been sitting in my garage for 3 days. Hooked battery up to a portable jumper which read battery amps at 6. 7. Battery jumped without issue. Took car to dealer who kept the car for 4+days and the dealer could not recreate the problem. Dealer advised me to lock my car doors as that could help turn computers off and not drain battery. Another 2 months went by and my battery needed to be jumped at least 4 more times if it sat and wasn't driven for more then 3 days or if I forgot to lock it. Finally on the morning of 4/20/20 I went out to start the car and the battery was dead yet again. The car had been locked but not driven for 3 days. When hooked up to the portable charger, the amps read 3. 6. The check engine light came on and the eye sight system was turned off per instrument panel. Jumped car and took it to dealership. Dealership kept car for 4+ days and informed me that the battery was replaced as it bad. Current mileage on car is 6633.

Battery dead 7 times (beginning fall of 2020) or drained too low to properly use vehicle causing all doors to lock (issue when stranded in non-populated area with child in car) or hatch unable to close. All items in vehicle are off. Appears to be electrical in nature and possibly related to in going Subaru power-gate hatch issues. Have also had hatch open on own stationary & low speed. Often left stranded. Hard pulsating and grind on brakes at low to moderate speed causing car to pull and feel like not going to stop in motion on curved road, highway, city street. Started within year (Aug 2020) of owning after 1st service at dealer for routine oil change. Dealer says nothing wrong at all. Subaru refuses to acknowledge issues even though other owners are experiencing same. Told by Subaru lame excuses like not driving enough, shut everything off, do not use electronics so much, etc. Car jumped 7 times so far. Took to dealer 3 times (9/29 brakes, 12/9/20 & 1/2/21 for battery and brakes) so far and dealer even had to charge battery (1/21)! unknown drain from somewhere. Every time happens have to have tail gate reprogrammed or not able to open.
