Assist problems of the 2019 Subaru Forester

Thermo control valve failure, p26a3 code, eyesight safety assistance warning light ,check engine light, pre collision braking light, lane assist light.

On Friday, December 15, 2023 I started my car, Subaru Forester touring 2019. After starting these lights came on the dashboard: check engine, flashing s drive, no eyesight, rab off. I was reading online that there have been complaints to NHTSA similar to my problem ( NHTSA id # 11490232, 12479843, 11511658, 11490977, 11479843, 11499756, 11480952, 11491752, 11474804) to name a few reports. This has never happenedbefore. The mileage on my car is about 54,400 miles at time of incident. It seems to me that there is a pattern here that needs to be resolved and the owners informed so they can get if fixed before it happens and causes safety problems for Subaru Forester owners. I am kindly asking your office to seriously look into this specific problem and help us, the consumers, to inform Subaru to fix these issues. I thank you for taking the time to read my letter.

There are two problems: 1 after the car turns off after stopping to save fuel it will fail to restart automatically and must be put into park to manually restart; 2 the car will try to change lanes indicating that the safety related lane change is malfunctioning. I have to fight the car to maintain my lane.

I noticed a serious safety issue with Subaru's lane keep assist safety feature: when driving on a busy highway over an area where the dotted line had been painted over with dark paint (by road workers to cover it up for a new lane to be painted) lane keep assist registered it as a line that still exists and forcefully steered me into the lane on my left. To avoid hitting the car in that lane, I forcefully turned to the wheel in the opposite direction. Luckily I am a healthy man who was able to steer myself back into my lane, but it turned my wheel with about three times the force of regular lane assist: I think many people including younger people and the elderly are at an even higher risk levels if they are unable to turn the wheel like I did. It was a much more forceful turn than Subaru's regular 'non-urgent' lane keep assist. There were no visual obstructions present that the eyesight camera was picking it was registering the old line that had been painted over. This is extremely important because not only is this a safety risk for any type of road work that paints over lines during construction or repainting, but this also poses an immediate danger to life and health to people driving on roads with lines that have been painted over and left in that condition. The computer registered the dark line, meant to visually cover up the old paint, as a white line! I confirmed that this is a systemic issue and not just incidental with me. I found a post on a Subaru forum where two people describe the same situation I had. I will link that below. . Read more...
