Rear lift gate drains battery to the point where the vehicle won't start. The tailgate will beep three times, but will not open. Within 24 hours, the battery is insufficient to start it. You have to do a manual override to open the lift gate. The battery, starter and alternator were all tested and had no issues. I have to keep a jump pack in the car as the issue has become more frequent. The local Subaru dealership in Mequon, WI said they would replace the battery, but won't replace the module identified in a technical service bulletin for no charge: This seems to be a very common problem with the MY19 Ascents.

I parked my Ascent rear facing inside of my garage to unload my groceries. When i opened my hatch at the front button, the hatch only opened halfway. The hatch would not close with the push of the button and had to be closed manually. Once I returned to my Ascent to go somewhere, the hatch sensor beeped repeatedly, while driving, until coming to a complete stop. Once driving continued, the sensor continued beeping. This occurred with two straight vehicle drives. The entire course of the drive. I parked the Ascent in my garage and returned to the car the next morning and the Ascent would not start. AAA came to do a jumpstart with no remedy. We replaced the battery with a new, borrowed battery and the car started immediately with no beeping. We charged the old battery and replaced the new battery and the Ascent had no other issues, including easy startup and no beeping. There were no warning lights for any of the issues including the hatch or the battery.

Electrical system repeatedly malfunctions. Intermittent starting and shut-off issues, rear hatch will not properly operate, per dealer the radio was replaced, and periodic unexplained battery drain issues resulting in replacement of battery. Dash warnings are displayed for no apparent reason. When radio was replaced there were still issues and dealer said it "would take a few days for the issues to resolve." Even after battery and radio replacement periodic shutting off car and restarting is necessary for volume control and station change. Safety could be an issue if car will not start, or shut off as related in a timeline attachment. Dealer is unable to reproduce periodic/intermittent issues.

I have a 2019 Subaru Ascent and my battery has died 3 times now. The first time was on May 2019 and the car would not start. I had to get it jump started by AAA and drove to the dealer where they ended up replacing the battery. The liftgate had somehow been triggered while in my garage and did not fully close and drained the battery. At the time it was suspected I had accidentally hit the FOB to trigger the liftgate to open but that never happened before and has ever happened since. Then in April 2020 car wouldn't start again. Car was jumped by AAA but when I attempted to drive to dealership it died again and had to get a tow truck to bring car to dealer. Battery was tested but not replaced. Dealer said I was not driving car enough (not driving at all during the pandemic) and needed to get a battery maintainer for battery which I did. I used battery maintainer when I was not driving the car regularly and car was fine until Oct 14, 2021. We had been driving car regularly for month so we were not using the battery maintainer as we thought the battery would be charged through the regular driving. But on Oct 14 the car would not start and when I tried to start it, all the dashboard and exterior lights were flashing. Plugged in the maintainer and after several hours the liftgate started beeping and then the front of the car started beeping. I had car towed to dealer and they replace battery again and also changed the power liftgate module to stop the drain on battery if door is open for more than 20 minutes.

In March of 2020, I took the car into the dealership due to the multiple times I had to charge the car, their answer was I wasn’t driving the car enough. They charged the battery and told me I needed to drive the car at least 20 minutes every couple of days at 50mph+ in order to keep the battery charged. In August of 2020 I had just loaded up the car to go on a vacation and when I went to leave the house the car would not start. After charging the battery for 30 minutes in the garage it then started. Fast forward to June of 2021, I have had to charge the battery 4 more times in order for it to start. The last time was when we were leaving a campground in May, 2021, and the car wouldn’t start due to the battery. Fortunately the campground had a charger and got us back on the road.

On numerous occasions (probably 12-18 times) over the last 18 months our new Ascent will not start because of a dead battery. I have discussed this numerous times with the dealer, they have even performed tests on it but claim that it passes all tests so there is nothing they can do. No doors are being left open or lights on, yet every few weeks this problem occurs. My wife cannot take the car to the store without worrying about it not starting properly and having to get a jump from someone.

I bought my 2019 ascent brand new in summer of 2018. I was driving yesterday and had my 3 yr old son with me. We stopped to get ice cream and sat in car to eat it. I turned car on enough to put windows down (no more than 3-4 minutes at most) and turned off. When I went to start car when finished ice cream about 10 min later my car wouldn't start and completely locked up. Couldn't even put in neutral or turn the wheel. I called aaa and the came and told my my battery health was only 30% and had a zero charge. He changed the battery for me and we were on our way but we were lucky to be in an area with help. Not always the case for phone reception in some areas. This car is not even 3 yrs old. Had it been summer it could have gotten extremely hot and very dangerous for my self and my son. It shouldn't have happened especially since we did nothing out of the ordinary. I have much less than 30,000 miles on the vehicle and it is well taken care of with regular maintenance and kept in an attached garage.

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.

My barely 2-year car continues to have electrical issues. It refused to start for the 4th or 5th time over the last several months... Twice in the past week. One, particular instance from this past week, I drove about a mile to my local library to do curbside pickup. I turned off my car while I waited 2 minutes forthe librarians to deliver my books. I had my two small children in the car. My car would not start back up. I didn't see this as a problem as a few months ago I purchased a portable jump starter because I have been having so many issues with my fairly new car. Well, I couldn't access my jumper because it was in my trunk which can only be opened when the car has power. It, of course, was raining, sleeting and snowing while all this was happening and my children were screaming and crying. Thankfully, one of the librarians had noticed I was having a problem and was able to give me a jump. This is probably the 4th or 5th instance in the past 6 months. However, this is the first time when my car was started and then wouldn't restart. Usually the instance occurs in my driveway. Frustrated, I made an appointment at my local subaru dealership for the following day, (february 19) to see what the heck was going on, they said they did a diagnostic and came up with everything being normal. I went home and a few hours later my family and I decided to take a long weekend out of town. The car was packed, kids were in their carseats and my car would not start. Paying $50k+ for a car that won't even start is beyond frustrating. I know someone who has the same car and has been having the exact same issues. Please let me know if you have any advice for me or any suggestions of next steps I should take.
