A week after my routine oil changed at 31K, the check engine light along with flashing "s" pop up. The next day the check engine disappeared. I was some what happy and continue to drive car as normal for 2 days, then check engine light came back again and this time is staying for good. I just can't believed that 4 years old car is having this issue. I've owned so many cars prior to this 2020 Subaru Forester, never once that those cars have problems like this one. I feel that i'm at risk driving without no eyesight or collision prevention warning.. when the check engine comes on, those two things are disable. After a long research and reading about so many people with same issues, i feel that they should be a recalling to fix the thermal valve control.

113,727 miles. 2016 Subaru Forester. 5 different warning lights all came on at the same time. Before that I noticed occasionally there was a delay starting again at a stoplight. Reputable mechanic replaced the valve body of the transmission. They said they service 2-3 Subarus for this same issue every month.

Car suddenly stopped accelerating several times over the course of several months, at seemingly random speeds, once even at a full stop when attemptign to begin acceleration. Required to turn it off and on again (in park, break still works) and it works again. I towed the car to the dealership, and they told me after a few days that they could not recreate the issue and nothing was certifiably wrong with it. The only thing that came up on the sceen was the EYE LIGHT system wording with a slash through it.

Starting up the car in the morning after a long day stuck in traffic (over 100 degree F weather), moved about 5 feet then the eyesight system stopped working, rear braking stopped, and power steering gave out - the car started and the engine ran normally. The car was abandoned as unsafe until diagnostics could be performed and a different car was used to get around . That evening the car started up fine, also the next morning to reproduce conditions. Tested the battery, which showed "good" (93% charge/40%healthy). I suspect that, in the morning the A/C, headlights, radio, backup lights, etc... put a large draw on the electrical system resulting in a system wide shutdown of adaptive features - However loss of power steering is insane and can easily result in death if it happens while driving especially while making a turn if the driver is not prepared/strong enough to force it. The linking of non-critical system to help the driver to an essential system is just asking for trouble.

Vehicle: 2024 Subaru Forester Touring Date of Report: [July 3, 2024] What component or system failed or malfunctioned, and is it available for inspection upon request? On June 19th, 2024 I noticed the side mirror of my 2024 Subaru Forester Touring has melted. This component is available for inspection upon request. How was your safety or the safety of others put at risk? The melting of the side mirror poses a potential risk of fire if it continues to deteriorate. This not only endangers the occupants of the vehicle but also poses a threat to nearby vehicles and property. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem has not been reproduced or confirmed by the dealer. Subaru has declined to cover the issue under warranty, attributing it to user-caused damage, which I strongly dispute. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by Subaru, who declined to cover the issue under warranty. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps, messages, or other symptoms prior to the melting of the side mirror. The problem was first noticed recently, within two months of owning the vehicle. Additional Comments: I have owned the car for less than two months and have taken meticulous care of it. The car is always parked in my garage, ensuring no sun exposure. The only place I have had the car washed is at the Subaru dealership, which further confirms that I have not done anything to damage the car.

Within one month the same thing happened. I turn on the car and the eyesight warning light is on (eyesight feature disabled), flashing "S" drive is on, "break" light is on, and check engine light is on. Due to this cruise control isn't working. My plan was to take it to a mechanic/dealership that Monday. By Monday morning, after about 15 minutes of driving, all warning signs disappeared. This exact thing happened a few weeks later (this morning). I started googling issues and seems like this is an issue for many customers and is just a malfunctioning Thermo Control Valve, no actual problem. What do I do about this? This is much less important - but also seems like a quality issue, at drivers side, the seat cover is starting to crack, looking like this is car is over 10 years old, we've had it for less than 4 years and this shouldn't be happening on a car of this caliber.

I picked-up my new 2020 Subaru Forester on January 2, 2020. Within two years the battery became too weak to start the engine. Since then, I've had to repeatedly charge the battery. Now a battery maintainer is constantly connected to the battery. I've seen online reports that multiple late model Subarus have had battery issues, and that Subaru of America voluntarily replaced batteries and addressed related electrical issues for some of its customers. Subaru of America has all of my contact information, but I was never informed of their voluntary fix of the battery issue. Due to the fact that I wasn't contacted about the battery failure issue, do I now have any recourse? Many late model Subarus have an automatic engine stop/start feature. I've read reports of Subarus not restarting in traffic, I therefore do not feel safe driving my 2020 Subaru Forester. Why didn't this dangerous problem trigger an NHTSA recall?

The battery on my 2019 Subaru Forester was replaced in September 2022. It was the best battery available offered at Les Schwab. But a few days ago, the battery was completely dead again and couldn’t even be jump started with my Jump N Carry after being parked in my garage for ~3 weeks. After taking out the battery and getting it fully recharged at Les Schwab, they also tested the battery saying it’s still in good shape. I suspect there is parasitic battery drain issue going on with this model.

I have had multiple issues with my car for the past month. First, my rear right wheel has been making a fan-like sound when going above 35mph and it gets louder until 70mph. It is most likely the wheel bearings going out but, I only have around 50,000 miles on the car. This seems to be a common issue with Foresters. Secondly, my…

I have had multiple issues with my car for the past month. First, my rear right wheel has been making a fan-like sound when going above 35mph and it gets louder until 70mph. It is most likely the wheel bearings going out but, I only have around 50,000 miles on the car. This seems to be a common issue with Foresters. Secondly, my rear Harman Kardon speakers have stopped working. This also appears to be a recurring issue with Forester's, with both their standard and premium sound systems. Lastly, my engine check light turned on and shut off my adaptive cruise control, forward collision warning, emergency braking, and rear automatic braking. I'm surprised that these issues are still happening to Subaru since they have been complained about by consumers for years.

At 7:30 am on 21May2024 I came out to find the car was dead, no electrical power at all, it would not start. I called Subaru customer service and arranged to have the battery jumped. When the tow driver tried to start the car, my car drained his battery in about 30 seconds. Because of the way my car was parked, the flatbed tow truck could not reach the car & I had to arrange for another truck to come pick up the car. That happened Thursday 23May2024 because my Subaru dealer did not have a loaner car available til then. That tow driver was able to start the car and said it was ok to drive it to the dealer if I didn't turn it off. So I started out and 1/2 mile from my house the battery died again & I had to arrange for another tow. Once I got the car to the dealer and they had a chance to check it out, I got a call about what was wrong. They said the battery was dead and a diagnostic test had confirmed that there was nothing in the car draining the battery, it was just dead and would need to be replaced. When I went to pick up the car and asked for a more detailed explanation of why a 2-year-old car's battery would suddenly just die, I was told that the battery didn't have enough amps for the needs of the car and they put in a battery with more amps (See attached service record). They also mentioned that Subaru was aware of this battery problem and there had been a class action settlement, but that my 2022 Forester was not covered by this settlement. I don't know if the old battery is available for inspection but this incident put me and others at risk when the car died in the middle of the road. My hazard flashers didn't work so there was no safe way to alert oncoming drivers of the hazard in the road. There were no warning lamps, messages or other symptoms of the problem before I found the dead battery Tuesday morning, or when it died on the road Thursday morning.
