2019 Subaru Forester

Battery constantly drains and fails to start the car almost from 2019 when I purchased the car. I’ve had to replace the original battery when the car was less than two years old and one year later the new battery has the same problem. No battery is able to hold a charge in this car and it continues to be a problem. Something seems to be draining the battery regularly. So that I won’t be stranded frequently, I needed to purchase a portable battery charger to start the car.

The problem cited below is on a 2019 Subaru Forester with 20,101 miles. The 'check engine' light came on when I started my vehicle as well as all the ADAS warning lights came on. All ADAS were inoperable. The car was drivable so I cautiously drove it to a Subaru dealership. While driving, I noticed the engine never warmed up. Running a cold engine causes an emissions problem and may be a violation of an EPA standard. The problem was diagnosed by the dealership as a faulty Thermo Control Valve Assembly, Part Number (21319AA010). Upon researching the problem on www.SubaruForester.org, I discovered over 240 similar postings about the same complaint on the same model car. I consider this to be a Safey issue with a potential of significant engine damage causing engine failure as well as making all the ADAS inoperable. Subaru of America is aware of the extent of this problem and should be made liable for recalling these vehicles and fixing this safety problem. The vehicle is currently (since Aug. 23, 2022) at the dealership awaiting a back-ordered part. I am currently negotiating with Subaru to have the part repaired under the 5 year/60,000 mile powertrain warranty. Please look into this issue since so many other owners of this vehicle are having this same issue. Thank You.

The contact owns a 2019 Subaru Forester. The contact stated that the vehicle was in the park position in a parking space but was unsure if the shifter was in park when without warning, the vehicle rolled down a hill and crashed into a chain link fence and burial wall. No warning lights illuminated. The air bags failed to deploy. No injuries were sustained. No medical attention was needed. A police report was not filed. The vehicle was towed to an independent mechanic but was not diagnosed. The vehicle was not repaired. The dealer was notified of the failure and the contact was advised to schedule an appointment to have it diagnosed. The manufacturer was not notified of the failure. The failure mileage was approximately 36,000.

I recently bought this vehicle (used) with ~1900 miles. After 1.5 months of owning the vehicle, I suddenly had several warning lights as well as systems disabled within the vehicle. The first time this occurred I was about 2 hours into a drive, and suddenly my eyesight disabled, check engine light came on, cruise control disabled, lane departure disabled, collision warning and automatic braking disabled. After pulling over to inspect, I also realized my trunk would no longer open. I took it to a dealership who said it was due to low battery voltage—despite there being no spectacular incidents to drain the battery since I purchased the vehicle. They recharged the battery and the problem was temporarily fixed. However, once I retrieved my vehicle from the dealership the check engine light and disabled features were still prevalent. I once again had them recharge the battery—despite there again being no events causing the battery to drain—to which the problem was solved. Again, about an hour into my drive back home, the check engine light and features suddenly disabled. This is detrimental to my safety as a driver—as every safety feature suddenly disables without warning during my drive.

2019 Subaru Forester 2.5L JF2SKAEC0KH576270 I use cruise control most of the time in all of my cars. Tapping the inc/dec button in my Subaru changes speed in 5 mph increments. This is very dangerous because my other cars use 1 mph increments. My use case is on long climbs I like to slow down my car 1 or 2 MPH as it works harder. When I double tap the Subaru it drops by 10 MPH instead of the expected 2 MPH. I want Subaru the update the PCM firmware to allow the user to switch to compatibility mode where single tap is 1 MPH and Long tap is 5 MPH.
