Repeated experiences of battery going dead after simply opening and closing doors a few times a day for four days. Engine was not started in this time. All interior light were off and rear hatch remained closed. Safety risk is being stranded in rural locations, at times with no cell service. Local Subaru dealer indicated I needed an authorization code from a battery lawsuit settlement to look into it. Lawsuit doesn’t include my vehicle VIN and only reimburses cost for battery replacement and possibly towing, not a repair. Research into the problem has indicated that this “parasitic drain “ can be remedied by replacing the defective older PRG Module with the effective newer one. This should be covered by the warranty on a two year old car. Local dealer would only refer to the lawsuit for direction. Suspect they are “buying time” until warranty expires to avoid doing the appropriate repair. See attached file for example of correct repair from another Subaru owner.

When I bought my car I was assured that it was impossible to lock the keys inside the car. Typically I put my dog in a special car harness and buckle him into the middle of the back seat.

When I bought my car I was assured that it was impossible to lock the keys inside the car. Typically I put my dog in a special car harness and buckle him into the middle of the back seat. He's 77 lbs. and tall. It's a bit of a project to get him all set. I'm leaning over and all my stuff is hanging off of me so I drop my purse onto the floor of the back seat and put the car keys on the console between the two front seats so I can more comfortably deal with him. I do this from the right side of the car as the child car seat is on the left side. Once he's buckled in I close the door and walk around to the driver's side and get in. On Oct. 7th I had taken him to a park to play. The temps were in the 80s and my car was parked in the sun. He's a Bernedoodle and does not handle heat very well. I buckled him in as usual from the right side and also put the keys on the console as usual. Then I closed the door. CLICK! Uh-oh! All the doors automatically locked! With the car in the sun and the outside temps in the 80s I can only guess that the inside temp had to be well over 100. I almost panicked. I thought of calling the police, but here in Portland they are slow to respond if they even respond at all. I banged on all the windows and thought of finding a rock to break one open. Then I remembered that I hadn't tried the back lift up door as it's an SUV. Thankfully it opened. But I had to crawl in over all my stuff in the back, over my tall, 77 lb. dog, and stretch out to reach my keys on the console in the front. Then I had to back out. This was not easy; I'm in my 70s. I shouldn't have to do that! So [XXX] was okay in the end. What if it had been my two year old granddaughter? What if the back didn't open like the side doors didn't? It shouldn't be that way. I called Subaru and they said they never heard of that happening. They said there was a lock setting but I couldn't find it. They said the fob battery could be low but there was no warning. I'm bringing the car in. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFO

Multiple occasions of vehicle cranking and not starting, or not cranking at all. Had original battery replaced at 35 months, and had new battery tested on 10/06/2022. The manufacturer mandated test showed the new battery was rated as a Fail, not meeting industry standards for this battery type/configuration. Dealer confirmed that there is no known repair available, including a reflash of the engine control module (ECM). Subaru is involved in battery lawsuit, and will not work on any battery related issues without forcing owner to register in the class action and give up rights to getting problem fixed. These actions are forcing us to own vehicles that the manufacturer considers unrepairable and are guaranteed to fail to start due to battery issues.

While on freeway at night on 9/28/22 about 8pm several dashboard lights activated including check engine, eyesight assisted safety light, steering and safety controls disabled, all at once! I pulled over and called Subaru for assistance. Called AAA. AAA suggested I drive vehicle off freeway. I went to brothers and he noted car not overheated and drive short distance home. Car manuals did not explain so many warning lights. Drove car to Roseville Subaru next day and determined that engine part had failed to leave for repair. Dealer service agent Raj would not provide any details, strange? Went online and found Subaru Service Bulletin #09-80-21 dated 2/28/22 indicating thermo valve defective causing warning lights, and to replace. I felt unsafe as on freeway at risk at night and am elderly. Subaru bulletin shows part faulty as of June7,21 per s.bulletin. Why not recalled by now? Unsafe to drive this car as steering, braking, and driver assistance systems all fail to operate at once and I was not sure if I could control car. Virtually every safety system shut down as simultaneously the speed control, collision monitoring and lane control all stopped working. Furthermore, dealer can't estimate when part is available or provide me a lender car. I am a cancer patient at risk! This car only has 17,000 miles and is not safe or reliable and the dealer won't help. Please help asap!

In less than 2 years of owning this car the battery failed putting me in a very dangerous situation. While standing in the middle of the road to make a turn into incoming traffic the car was off because of the auto stop-start system. As I released the brake and tried to accelerate to cross the intersection the car failed to restart automatically and stalled as if the battery did not have enough power. I had to place the car in parking and restart it again in the middle of the road. This happened multiple times. I took the car to the dealer and it was confirmed that the battery was bad and it was replaced. The new battery was good for sometime but lately it feels that it lacks power again, specially to restart when off from the auto start-stop system. This problem is very concerning as it can cause a major accident if unable to restart when expected.

Battery will not hold a charge. Battery frequently needs to be recharged. Bought a portable jumper, to ensure vehicle will start away from home where the battery would otherwise be charged in the garage.

I own a 2015 Suburu Forester with just under 60,000 miles. i have noticed the engine does not start right off, making me nervous. I drive a lot and don't want to get stranded. On 9/19/2022 I went to the Battery Outlet in Quakertown and they said i have a battery drain. They did not think the battery needed to be replaced but to me, the greater issue is WHY IS MY BATTERY DRAINING TO BEGIN WITH. Of course, the car would be available for inspection. No I am not at risk. I have to ask my mechanic to check it out. I bought the car in 9/2020 and due to covid I did not use it as much as I am now. No warning lights on this; I can hear the engine struggling to start.

19V297000 · Electrical System:ignition:switch

Apr 11, 2019

Subaru of America, Inc. (Subaru) is recalling certain 2009-2013 Forester vehicles, 2008-2011 Impreza vehicles, 2008-2014 WRX vehicles, 2005-2014 Legacy vehicles, 2005-2014 Outback vehicles and 2006-2008 Tribeca vehicles equipped with a mechanical key ignition switch installed as a replacement part. The ball spring inside the switch may break, reducing the strength of the ignition switch. If this occurs, the weight on the key ring and certain road conditions could cause the ignition switch to move out of the run position to the accessory position, turning off the engine.

Consequence & remedy

Consequence: The engine turning off unexpectedly can increase the risk of a crash. If a crash occurs under this condition, the air bag may not deploy, increasing the risk of injury.

Remedy: Subaru will notify owners, and dealers will inspect the ignition switch, replacing the ignition switch, if necessary, free of charge. The recall began May 10, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUF-91.
