This vehicle has approx. 45,000 miles and the electrical has failed. We have replaced the battery and tested all components in which they then operate fine. However overnight the battery fully drains, leaving us with no vehicle again. This vehicle has no accidents, maintained every 3 months and the health report even shows no issues/errors. No other symptoms have been noted. this car works and runs 100% like it did day 1 up until 3 days ago. Where it has died overnight every day. Luckily my husband is a mechanic as he indicated the last instance of a new battery going in, the dashboard was flashing and going haywire to the point that it wouldnt stop until he removed the battery. He indicated that its likely this would have been an electrical fire if the battery was not removed therefore could have caught on fire with myself and our 14 month old inside. There were no warnings, no alerts, no vehcile safety alerts, the mysubaru app in fact still says we have a 100% healthy vehicle.

While driving the vehicle suddenly stalled and stopped running. The dashboard illuminated with most lights and the check engine message came on the screen. I was thankfully able to get into the shoulder on the road safely without creating an accident or getting injured. The vehicle would not start again and had to be towed to the dealership. I am now out $1800 because I am slightly over my powertrain warranty in mileage on the vehicle. This is a known issue in bulletin: https://static.nhtsa.gov/odi/tsbs/2022/MC-10208664-0001.pdf I am not only disappointed with Subaru of America and NHTSA that this is not already a recall but I am also willing to seek legal action and compensation if this repair is not going to be covered. There are many incidents and reports online of similar issues: https://www.subaruforester.org/threads/2019-thermo-control-valve-assembly-and-warranty-merged-thread.823510/ https://www.carcomplaints.com/Subaru/Forester/2020/drivetrain/power_train.shtml I have filed a case with Subaru of America corporate and am waiting to hear back. Someone is going to cause an accident or end up dead because of this faulty part. It is borderline criminal that this is not already a recall.

The Subaru starlink system has no controls around transfer of ownership. I only discovered this after receiving a $150 charge 2 months after I traded in the car to a Subaru dealer. Even after trading in the car I was able to unlock, lock, start the car, and track the cars location. This represents a significant safety risk to the consumer and must be addressed immediately.

When I was driving this car one night, every dash light was suddenly activated and remained on -- and as a result all safety features were deactivated. When I was able to do so, I touched the battery cables together to reboot the system. I had to do this 3 times over the course of 4 days. Realizing the problem was chronic, I took the car to the dealership (a 2 hour drive), where a service tech explained the problem 'was caused by a low battery.' This car is only 2 years old. A new car battery should last longer than 2 years. It thus seems to me the battery was defective or the car improperly drained it somehow. More important, there is no warning that a 'low battery' -- one which can easily start a car -- could still deactivate safety features while driving.

Engine shuts off when coasting into a turn when car is moving at less than 5mph. Causes loss of steering. Will restart if gas pedal is pumped. Dealer can find no problem. Does not happen predictably and can not always be replicated. Very dangerous.

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.

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.

BATTERY DRAINS constantly and car will not start. This has happened several times the past month. I understand that it is an ongoing issue with other Subaru's. This is dangerous and must be fixed. This issue has happened 3 times in 2 weeks. 8/1, 8/13, 8/15/2022

There are various lights on on the dash of the vehicle when nothing is seemingly inherently wrong with the vehicle. I notified the dealership about this issue, the dealership claimed that special parts were ordered but I still have not been notifed of their arrival. This puts my safety at risk due to the fact that I am not sure wether the car actually has an issue, or if it is a mere malfunction. The vechicle is now shaking.

The contact owns a 2020 Subaru Forester. The contact stated that the battery was continually being drained and needed to be recharged frequently. There were no warning lights illuminated. The vehicle was taken to the local dealer however, a cause for the failure was not determined. The dealer recharged the battery. The vehicle was not repaired. The contact related the failure with electrical system defects which consistently drained the battery. The contact recharged the battery after each time the vehicle was driven. The manufacturer was not notified of the failure. The approximate failure mileage was 2,000.
