2019 SUBARU FORESTER Complaints

The check engine light came on and all of the eyesight components on the car were disabled as I was traveling down the highway at 70 mph (this included the adaptive cruise control, the lane departure warning, forward collision warning, etc). In addition, the engine thermostat light came on and the heater and defroster stopped working. It was cold and rainy and the window started to fog up and I was unable to clear it without a functioning defroster. This was definitely a safety issue and I had to stop driving. The car was taken to a subaru dealer today and diagnosed with faulty thermo control valve. The technician told me the car should NOT be driven in this condition due to the problem being in the engine coolant system. This is a known issue on the 2019 Forester, and other Subaru models as well, and has a TSB originally issued in Sept 2021. (#09-80-21) My car has 70K miles and therefore is just out of the warranty period. I will have to pay over $1500 to replace this part and because it is a safety issue I have no choice but to pay for the repair. It is a part that is known to be defective and I am requesting that a recall should be issued before others are also put in potential danger and/or forced to pay large sums of money to get it fixed.

I own a 2019 Subaru Forester. Approximately 5 months ago, I experienced a failure in the auto start-stop feature. My car intermittently shuts down when stopped at traffic lights or in the middle of an intersection. Subaru conducted a diagnostic assessment to address the issue, but they couldn't identify any problems. This has happened about six times within the last five months. They claim to have never encountered this issue before. The temporary solution is to turn off the car and restart it, which is not safe when it occurs in the middle of an intersection. Following my dealership's recommendation, I replaced my battery with a standard EFB battery, However, the same issues persisted. Notably, the problem consistently occurs after driving on the highway for approximately 60-80 minutes and then coming to a stop at traffic lights. It is evident that the issue is not related to the battery. This issue raises significant safety concerns, especially when making left turns after coming to a stop at intersections. The sudden shutdown of the vehicle in the midst of an intersection can pose a substantial safety risk to both the driver and other road users. It not only creates a hazard in terms of traffic flow but also increases the likelihood of accidents and collisions. Given the critical nature of this safety concern, it is imperative that the problem be promptly addressed and resolved to ensure the safety of all road users.

2019 Subaru switched from a thermostat to a "Thermo Control Valve" (TCV). They eventually redesigned it in 2022 due to so many failures. Mine failed rendering the cars "eyesight", lane assist, cruise control and brake assist useless. Check engine light and oil temperature light remain on. Engine code is P26A6 and P26A5. Subaru has known about this issue for years yet charge $600 for the new "Thermo Control Valve" and $1,000 to install it. These "TCV" valves fail indiscriminately with mileage not being a factor, rather the product itself. Any search online and you will find hundreds (if not thousands) of people affected in and outside the warranty. No recall has been given.

The temperature control valve (TCV) has gone bad and so the check engine light is on and reverse automatic braking and the Eyesight system is disabled. The problem with the temperature control valve is unrelated to the safety systems, however, when this valve goes bad, these safety systems are disabled automatically.

Three times in the last week or so, coming to a stop, in traffic, the car throws a warning about the EyeSight not working and it shuts the car off. The first time I was still rolling and had not come to a stop. The other two times I was just barely stopped and it happened. It would be horrible if it happened while driving fast. You have to put it in park and hit the start button to turn the electrical off and then hit the button again to start the car. Windshield is clean. No visible obstruction to the camera system. Clear weather every time. No rain. Daytime driving.

2019 Subaru Forester with 38,000 miles. Heat stopped working. 30 minutes later, check engine light came on. Warning on dash stating that Eyesight cannot turn on. Lane assist and adaptive cruise control will not turn on. Mechanic found it needs the Thermo Control Valve replaced or the car will have no heat and the engine can overheat. Quoted a $2,000 repair cost and 3 weeks before we can get the part.

The contact owns a 2019 Subaru Forester. The contact stated that the front windshield had been replaced two times and the failure had reoccurred three times within the year. The vehicle was taken to the dealer the first two times the failure occurred. The contact stated each time the dealer replaced the windshield but could not determine the cause of the failure. The failure reoccurred. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 118,000.

This is the second time I am reporting this issue in the past few months. Three times this week my car has gone into the "gas saving" mode at a stop sign or red light and has not turned back on. I get a warning and need to turn the car off and then back on. This has put me in very u safe situations as people assume I'm going to start driving once the light changes and I've been nearly rear-ended multiple times, screamed at, cursed at, etc. This has happened an uncomfortable amount of times and I think you should do an investigation before I, or someone else gets hurt!

Subaru has issued a service bulletin regarding this issue. The vehicles auto engine on/off (gas saving feature) fails to restart while driving due to OEM battery is known to be too weak. Only way to resolve the issue is to replace with higher capacity battery requiring new battery tray and additional new equipment. Current, customer has to pay repairs out of warranty. Incidents are frequent and reoccurring.

This is a follow up from previous complaint 11525953 dated 6/8/2023. My subaru forester stalled again on 8/2 at an intersection after 15 minutes of driving, and then again on 10/4 at an intersection after 45 minutes of highway driving. There are no warning signals or any indication of engine problems. I replaced the air filter in June hoping that might solve the issue.
