I have experienced problems with the rear lift gate on multiple occasions. It is working intermittently and locking me out. The beeping while the car is in motion is continuous and it drained the battery; I had to purchase a new battery. Another time we had to disconnect the battery (as suggested by the dealership) and reconnect it to fix the problem.

What owners say
The battery is draining so quick that the car doesnt start at all. The battery drained completely in 3 days and it’s happening more often.
Battery draining. Bought car from dealership preowned with 25k miles. Owned it for 3 weeks and so far -Battery dead, jumped it, good for a day then dead again. -took back to dealership, said bad battery, replaced it, good for a week and a half then dead again -scheduling to go to a subaru dealership for diagnoses Ive read about the DCM on these vehicles trying to connect to 3g towers continously even when the car is off. The 3g towers are no longer in use in the USA. Subaru should have a software update to remedy this issue but have not found that thus far. Just a lawsuit over this issue.
The battery died after two weeks of replacing it, later revealing the alternator failed. Parts are not available, Subaru kept them My safety was at risk because the lights on my dashboard Christmas Tree'd letting me know something was wrong. Within a couple of blocks I had no power steering and was dying on a busy street. The car was so dead that I couldn't even turn on my hazard lights. The car was jumped by Subaru, the tow truck driver left and the car died two blocks later. This time in the middle of the busy street. The vehicle was towed to Subaru who replaced the battery we bought two weeks earlier. We asked if they check the charging system and they said yes. The battery light was on before we left the lot. We made them keep the car so we wouldn't die in the middle of anymore busy streets. Days later they determined it was the alternator. The car had 26,000 miles on it. I don't know what Subaru did with the parts. They said they needed them as it was a warranty replacement. The battery light never came on before the car died. First the Eye Sight Disabled light came on then many lights on the dashboard flashed on. This happened a couple blocks prior to me losing power. I found the first place I could to get off the road. Two weeks prior when the battery died, the eyesight disabled light came on and the battery light. That time I got home and we replaced the battery. Therefore when the eyesight disabled light came on, I knew something was wrong but thought I had time to get out of the way. Then everything died. The worst part is that hazard lights didn't work.
After 3 years the battery died completely and the car was unable to start, I replaced the battery with AAA and the next the day, it also died again. I was able to jump start the battery the next day and continued to use the vehicle. I have the battery for about a month and again the battery on the vehicle had drained where I was unable to start the car but I was able to jump start the car with a battery jump starter. There has been 3 occasions of battery just draining and I have a new battery installed. I called Subaru and they mentioned that there could be an issue with the back latch no closing which could drain the battery, however, the have confirmed that the back door does completely close and lock or it will just automatically come back up. I feel there is something wrong with the electrical system and AAA has confirmed with me the the alternator or the battery is functional.
The vehicle has a parasitic battery draw. I purchased a new gel cell (Redtop) battery, the most powerful one that fits the car, and was reimbursed by Subaru. The car battery still goes totally dead after about one week, even with occasional driving. I have to carry a jump battery in case I am traveling to insure that I can get the car started when I stop.
Car battery died in store parking lot. Low mileage (24,000). I do lots of short trips and this is a reported problem for 2019 Subaru Ascents. I had to wait 2 hours for someone to bring a charger to drive to auto parts store fire replacement battery.
Battery keeps dying.
Battery draining problem
Arrived at my car after traveling for the weekend, and arrived to my car to find out the battery was dead. Nothing on, lights were in Auto like normal. The last thing I did after getting out of my SUV was grabbed my suitcase from the trunk. I think it must not of latched correctly and it drained the battery. There is supposed to be a light delay to preserve the battery but it did not work in this case. I still can't open the trunk. This happened once before while camping with our dogs we left the tailgate up to unpack and pack the SUV. We loaded the dogs up to leave the campsite. When we went to start the SUV the battery was dead. Seems leaving the tailgate open drains the battery. The problem is even after we got our car jumped and the car was operating okay, we could not open the tailgate. It just makes a beeping sound like it wants to release but will not open. The manual handle should allow anyone to open the gate even if there is a electrical disturbance. This is a safety issue related to not being able to get our dogs out of the cargo compartment. Our dogs are over 100 lbs and their travel crates are large and need to be opened from the rear of the vehicle.
