2019 Subaru Forester

Over a dozen times now, when at a traffic light, the automatic on/off feature turns the cars engine off. When you take your foot off the brake to reactivate the engine, there is an EyeSight Disabled warning and the car stalls and fails to turn off. You have to turn the car completely off to restart it. I have previously brought the car into a Subaru dealer for servicing after this happened. It has continued happening since then.

2019 Subaru Forester Premier. 6/29/23 All ok while driving for 3 hours on highways. Never had any issues before. I stopped car to take a break, when I restarted the car. All the warning lights lit ou and eye-site was off and could not be turned on. Check engine light on along with many others. Had 30 minutes more to go, stopped a few more times to check on the engine compartment - all ok. Brought it to the dealer today, 6/30/23, they were going to need 4 hours to replace a Thermo Coupler Valve? Issued a loaner car, and said Subaru will cover it under warranty even though it has expired. Only 24500 miles on a 2019 Forester.

On January 1, my wife was returning home from a grocery run when our 2019 Forester’s dashboard suddenly lit up like a Christmas tree--Check Engine, EyeSight, Anti-Lock Brakes, Anti-Skid, and blue Temperature lights all came on simultaneously. The Forester did not lose any appreciable power but the heater stopped working and was only blowing cold air. My wife was only a couple of miles away and brought it straight home. I checked under the hood but had no idea what was going on, so I drove it over to my local Autozone for a scan, and it came back with the 'P26A3' Code, as well as 'P3300,' and 'P2100' (Throttle Control Motor-Circuit Open). I brought our Forester back home, did some online research, and discovered that this code typically indicates a thermal control valve assembly (TCVA) failure. Our vehicle's 60,000-mile powertrain warranty had just expired but fortunately, we live near a reputable repair shop which was able to take the Forester in the next day, confirm the codes and TVCA failure, and then make the repair. Further research revealed that this appears to be a widespread quality control problem and typically costs affected owners between $1,100 and $2,000 to fix beyond the expired standard 35,000 mile /60,0000 mile powertrain warranties. In fact, there is a Subaru Forester Owners thread that runs over 33 pages with 654 posts from other owners throughout the world reporting the very same failure over the past year, nearly always between 50,000 and 70,000 miles. (https://www.subaruforester.org/threads/2019-thermo-control-valve-assembly-and-warranty-merged-thread.823510/) This past week, a friend of mine who's an old school mechanic, took the old TCVA apart and discovered that coolant had actually leaked into the part's internal electronics and shorted them out, causing the failure. He was amazed that the short circuit did not damage my Forester's computer. It's certainly a design and manufacturing defect and a recall should be issued by Subaru.

Eye-sight system shutdown and the car, although it was drivable, ran rough. Since there is a huge reliance on the monitors as they are designed to "forward think" to aid the driver, this was a major disruption to the driving experience. Not knowing what the disabled components affected, was a huge cause for alarm. Upon seeing the check engine light come, my wife brought the car home and I hooked up my device to read the code (P26A3 - showed up). Then I looked up that code and was directed to multiple incidents where that very same thing has become frequent on this model and a few others like it. We called the Winston-Salem NC Subaru Dealer (Flow) and they suggested we bring the Forester in for a check. Once they checked the vehicle out and confirmed the code we mentioned, they told us the "TCV" problem was found on our vehicle and they have seen others with the same problem. They even had the parts in stock to make the repair that day! They kept the parts and said they were going to be sent back to Subaru of America for analysis.Interesting detail: once we drove the repaired vehicle, it ran better than it ever had and the only work they did was to fix the TCV issue (according to the repair paperwork).

March 9, 2023 at 7 AM, I was driving in Philadelphia and traffic had slowed slightly and I was going 5 MPH, coming to a stop in traffic when my car completely "froze", and all the lights on the dashboard came on and it said "auto start disabled" and my car would not move. I tried to hit "start/stop" button but nothing worked and I tried to hit my blinkers so I could warn the cars behind me, but nothing worked in the car and it was stalled. This was the situation for 4 full minutes. I am lucky the cars behind me were paying attention and did not hit my car when it abruptly stopped like that with no warning at all. I am really concerned about this car's safety. This issue occurred to the same car in 2021 and I made an incident report then as well. The dealership said it was due to a faulty hood sensor which they replaced but the same exact thing happened a few times in 2021. I think there is some problem in the car's wiring or electrical system that is not being addressed. This is unsafe and a safety hazard for me and other cars on the road. Subaru needs to address this.

First, the driver's side window would not go up when rolled down, but instead went up and down on its own, until I stopped the car and restarted it. A few days after that, on Friday, January 13, 2023 while on my way to work, I was stopped at a traffic light. All of a sudden beeping started happening, the "Eyesight" light came on, other things were showing, and the car died. I was too freaked out to notice anything else. I put the car in park and restarted it, and it was fine. Today, January 16, 2023, the exact same thing happened when I was stopped at a traffic light, again on a very busy highway. I am extremely worried and will be contacting the dealership tomorrow.
