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.
Car has been not able to roll up driver side window for a year randomly. Suddenly 3 years old and battery is draining and RAB and Eyesight and engine light on. Took in and saying can’t replicate window after they DID replicate it 3 months ago and did not solve issue. Did battery parasitic draw and numerous parts of car are draining battery. Cannot find source.
Battery drains and goes dead at least once a month. Battery was replaced by dealer and still having battery drain issues.
Battery went dead after leaving tailgate open for 1hr
Battery dead, once 6 months ago when rear gate opened and closed several times before staying open for a few hours before neighbor asked if I knew it was open. Battery dead after driving to 2 stops on 10/24/22 then dead again in airport parking on 10/28/22 when returning from trip. Took into dealership 10/29/22 and problem confirmed although not sure if it is the battery or charging the battery. No warning lamps. Have to wait by myself until I can get a jump start. Don’t know when or where it might not start, puts my safety at risk by not knowing where or at what time of day or night I might be stranded.
Battery drains fully from unknown reason. This has happened at least 3 times since purchasing the vehicle, brand new, in 2019. I have had to call roadside assistance within the first year and have purchased a 2 other new batteries. There were no light or other electrical items on which would have drained the battery. It’s starts slow where I need to jump start the vehicle about 5 times before the battery is completely dead. It puts me and my family at risk of being in an isolated or unsafe place when the battery dies and need to wait for roadside service. To my recollection there were no safety checks completed for this issue. I do have a scheduled appointment at a Subaru dealer on 10/27/22 where I will ask them to look at this. There were no warning signs or indications prior to the battery draining.
2019 Subaru Ascent experience battery drain. Was able to start after jump and had 13 volts when returned home. Next morning it did start, barely, but was down to just above 12 volts. Appears to be the electrical system drain.
Subaru ascent issues with electrical system and battery. Engine cranks longer than it should before starting- anywhere from 5 to 25 seconds. Battery dead multiple times. Have taken to Subaru multiple times, they replaced the batter once but have ignored repeated requests to fix the issue of parasitic battery drain from faulty electrical system.
