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.

I was parked curbside waiting for a food order with my two kids in the back. After about 5 minutes of the car being turned off while we were in the car, and once we got our food. I went to start up the car and it would no longer start. It's worth noting that the infotainment system stayed on since we were still in the car. And even with the push button, even when I tried to completely power down the car, the car would not turn off. Then when I tried to start the car again with the push button start, it would no longer start. But the car had plenty of voltage. I also couldn't get the dome lights to turn off and the infotainment system was still on. I couldn't power everything down so I could do a clean start from zero. When the parking lot security brought a booster pack, since the terminals and cables had no indication of positive and negative we didn't try to jump the car. We pressed the push button to try to start the car on it's own again and the lights would flash and there was a rapid ticking sound. We left it alone for another five minutes and it started right up.

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).

Battery drain. Parked car will not start even though the battery is less than one year old. It appears the oem battery is undersized or there are electrical battery drains when parked. Second time in two weeks that car will not start.

I purchased my 2020 Subaru Ascent limited in October of 2019 and have experienced several discharges of my battery from the liftgate being open throughout the night, possibly from pocket-activation of my key fob. Luckily for me, this problem has occurred only in my garage, thus far. I have seen in several forums related to Subaru outbacks and Ascents that this appears to be a common problem and nobody, including me, seems to have gotten any satisfactory answers from any of the Subaru representatives.

Car would not start, was dead, it was in the garage, and there was no way to put it into neutral to roll it out. Had to call roadside assistance. They jumped the car after getting it out of the garage and was able to take it to the dealership

This is a brand new car. The battery drains overnight when the car is parked. The key fob is min 30feet away from the car. The battery has drained three times in the past 7 months and renders the car useless when you need it. I have made sure that the lights are off and nothing is left switched on and still the battery drains. There are several similar complaints from 2020 Subaru Ascent owners and it would be great if you can investigate this issue futher.

Ascent

  • 3,600 miles
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.

While driving down the road on a trip, my 2020 Ascent suddenly lost all audio from the infotainment and gps system. Then after the vehicle was parked overnight, the battery was completely dead. No systems were left on at the time the vehicle was parked, so the cause of the dead battery and the loss of audio is a mystery.
