Subaru Forester electrical problems

I tried to unlock my car but the remote didnt work- I had to use the blank key inside the remote to get in the car. I couldn't start the car- my husband tried to jump it- that did not work- I called AAA they tried jumping it - that didnt work-- AAA told me the battery was good but totally out of charge 0%-- I called the subaru salesman I bought the car from & he walked me thru alot of steps & we couldn't find anything wrong besides the battery!! he told me to have my husband try to give me a jump again & after 4 hours the car turned over! What caused it????? no idea??? the next day (7/5/21) I took it to an auto parts store & they tested it out- alternator-perfect--- battery @ 550 with the max 620--- today I read an article about Subaru batteries failing! well mine did for no apparent reason--- maybe they should all be recalled!! I missed my 1st day of vacation due to this!!

Dome light left on overnight. Battery was completely drained, not even the doors would unlock. Called a jumpstart service, they could not jumpstart it without getting thicker jumper cables. Store-bought cheap jumper cables would not work. Second jumpstart service worked, I left it running for 1hr before cutting engine and parking for the night. The next morning, battery was dead again. Called tow, took it to dealership, they replaced the battery. One month later, dome light was left on again, battery was completely dead again. Once again, store-bought jumper cables would not work. Jumpstart service came with thicker cables and got it started again. Dome light has not been left on since then.

The battery died on several occasions. I had to purchase a portable jump starter to keep in the vehicle for times that the vehicle would not start. I had the battery replaced by the dealer, but the same issue happened again. In the winter of 2020 I ended up purchasing an after market AGM (Advanced Glass Mat) battery for the vehicle.

The battery in my 2017 Subaru Forester was completely drained of power in 4 days of non-operation of the vehicle. The battery in question was installed on 10/4/2020 by my Subaru dealer to replace a battery that also had drained of power and would not take a charge. I presume the current battery was fully charged by my trip home to Arlington, VA from Philadelphia, PA on July 5, 2021. I tried to start this vehicle around noon on July 10, 2021 only to find that the battery was completely dead. The electronic key did not work. All internal screens are black. No response to key in ignition; not even a rattling noise. This is two dead batteries in less than two years of ownership. The current battery is only 9 1/2 months old.

Battery keeps dying without daily use. I drove my vehicle less than a week ago, no lights left on, nothing in the charging ports, no doors open, and still the battery didn't have enough power to start. I've had to call AAA and have neighbors jump start my vehicle a few times but when I get my battery tested I'm told that my battery is fine and that I do not need a new one. Something is draining my battery and I don't know what.

Battery hesitated when starting engine within 7-9 months of ownership. Spoke to mechanics and service staff several times then and later and was told I need to drive it every 2-3 days to keep battery charged. By 18 months of ownership it was completely dying by fourth day of not driving so I took it into service. After 9 days in service and then service not waiting my advised 4 days to cold start it, they said it’s fine and drive more or get a battery tender. (And that the battery compartment will not accommodate a larger, more powerful replacement battery!). So I purchased a battery tender and keep it attached at all times, just in case. And, I had to purchase a portable charger to keep in my car because an outlet isn’t always available and I could get stranded somewhere. I bought this car upon retirement as my forever car but I do not feel safe or comfortable owning it. I shouldn’t be forced to drive my car every 2-3 days. And should I really be going through all this when purchasing a new car?

With engine running and shift lever in Park (CVT transmission) driver is unable to turn the engine off or remove the ignition key from the steering wheel. This occurs sporadically/unpredictably such that driver has no forewarning and cannot take proactive steps to avoid the problem, resulting in instances where driver is forced to leave the car running in situations that present safety concerns. (Examples: in a garage or enclosed area; when temporarily exiting vehicle necessitating leaving the doors unlocked; etc.). The problem is widespread in Subaru vehicles and consistent with problems exhibited/described in Subaru Technical Service Bulletin (TSB) #16-112-18R for which no recall has to date been issued for corrective action by Subaru. Driver was told by Subaru of America that a diagnostics test is needed by a Subaru dealer to verify existence of the problem (which as stated occurs unpredictably) at driver's expense (locally approximately $140), with repair coverage of defective/poorly-designed shift or electrical components not being covered by Subaru beyond the standard warranty period for the affected vehicle. estimated cost of repair for defects as listed in the TSB (per on-line sources)...$400-$650 depending on dealer and geographical location.
