general problems of the 2019 Subaru Forester - part 2

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.

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.

1 . Termal control valve 2. Traveling out of state and engine light came on 3. Warning light (check engine was on) 4 confirmned by dealer 5. All lights on dash boards on.

Thermo control valve needs replacing at 34k miles. Not covered under warranty. Also needed new tires at 30k miles and now faulty ignition coil.

Thermo control valve malfuncitoned, causing check engine light to come on. Car only has 72k miles on it, so dealership (mcdaniels Subaru, columbia. Sc) said they couldn't repair under warranty. Even though car has 100k powertrain. To get to this part you have to remove intake manifold, so I don't see how it's not considered part of the powertrain. While check engine light is on, none of the safety features of this car function. From internet research, this part is going to fail, (part has been redesigned due to this), it's just a matter of whether it fails within your warranty period or not. Mine was not.

The thermo control valve (tcv), responsible for regulating cabin temperature and engine temperature failed, causing the vehicle to go into safe mode and was not drivable.

My wife was driving her 2019 Subaru Forester (purchased new) and the eyesight disabled and the check engine light came on. The car was still running, but not as it normally would. It had less power but would still maintain the speed limit. At home the car idled differently, like it was running too rich or too lean. The exhaust also smelled funny.

On our way to a vacation in NJ, we were driving on the expressway and a deer jumped over the rail into the hood of the car. The car immediately started to smoke ( dark black). We got out of the car, retrieved two luggage bags, and the car burst into flames. All within 60 seconds of hitting the deer. About five years ago, same thing happened to my daughter driving a Subaru wrx…. Twice in the same family…. No recall?.

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.

Dear national highway traffic safety administration, I am writing to report a safety issue with my 2019 Subaru Forester, which I believe may affect many other Subaru vehicles as well. Specifically, I have experienced a problem with the thermo control valve, which has caused the eyesight safety features to be disabled and potentially poses a safety risk. I first became aware of this issue when the eyesight safety features on my vehicle were automatically disabled due to a malfunction. I brought my vehicle to a Subaru dealership for an inspection, and they determined that the thermo control valve was faulty and needed to be replaced. It was alarming to learn that many other Subaru owners had experienced the same issue, and some had even experienced engine failure as a result. The eyesight system is a driver assistance technology developed by Subaru that uses cameras and sensors to monitor the road and surrounding environment, alerting drivers to potential hazards and providing automatic braking support if necessary. This technology has been recognized as one of the most advanced driver assistance technologies available, and is designed to help prevent accidents and reduce the severity of collisions. The eyesight system includes features such as adaptive cruise control, pre-collision braking, lane departure warning, and sway warning, which work together to provide a comprehensive safety package for drivers and passengers. These features are critical in keeping drivers safe. I am concerned that this issue may be more widespread than initially thought, and that it may pose a safety risk to drivers and passengers of affected Subaru vehicles. The faulty thermo control valve can cause the eyesight safety features to be disabled, which can lead to reduced safety performance, accidents, and potentially harm to drivers and passengers. Sincerely, davide alves.

When I turn the car on it flashes check engine eyesite failure which then turns off the ability to use cruise control, crash detection, lane assist, ext. We called dick hannah Subaru and the code came up as p26a5 engine coolant bypass valve a position sensor. They said a thermo valve needs replaced and they’ve seen that happen a lot in 2019/2020 Subarus.

Rab disabled, eye sight disabled, I drive disabled, check engine light came on. Car drives like it's is in sport mode with very touchy throttle. Pulled a code and it's the tcv. It's a known issue by Subaru with a part that has since been revamped but with thousands of vehicles on the road affected. Should be a recall. Contacted Subaru of America with no response so now a $1,900-$2,500 depending on dealer cost is being pushed on the consumer. Vehicle currently has 80,000 miles but as a Subaru ambassador I used to put a lot of miles on going to events, meets and typical camping and outdoors activities you expect out of these vehicles so my milage is slightly higher than the normal work commuter.

Multiple incidences approximately 8 since 2022. Stopped for 8 months with new battery. No issues are recorded in the computer in any of the troubleshooting visits. Normal sequenced of events: stopped at a stop light, start/stop engages, take foot off brake, start providing gas, car stalls, dashboard lights up, alarms, provides instructions to place the car into park and restart, and the car restarts after that is performed. Danger situations that this has caused: aggressive car behind not paying attention to the stall and green light with no one behind and car coming up behind quickly while you are attempting to restart the car. As this cannot be disabled without modification to the car this created a dangerous situation.

The auto start/stop occasionally malfunctions where the auto stop turns on as expected but then doesn't turn off when you try to use the accelerator. It has happened when a red light turns green the car stalls, displays an error message and you have to restart the car to get moving again. This recently happened to me at a very busy intersection and was very dangerous.

Driving home for 15 minutes. Parked on left turn lane, slight incline. When traffic light turned green, I stepped on the gas and the engine stalled. I remember seeing "eyesight disabled" warning light come on. I put vehicle in park, shut it off, and turned engine back on. I was able to drive home. Possible system failure - fuel system, auto/stop feature? yes, available to inspect safety - 5:30pm heavy traffic on 4 lane highway0. Blocked traffic turning left. No where to pull over. Have not taken vehicle to mechanic or been inspected. I saw no warning lights prior to vehicle stalling, or experienced any engine anomalies.

2019 Subaru Forester failed thermo control valve. There are literally 1000s of complaints on this issue and soa refuses to issue a recall. Subaru has issued a bulletin to replace the faulty design with redesigned part. When this fails the car goes into limp mode and all lights come on. Very dangerous and quote frankly completely irresponsible that Subaru refuses to recall this failure. I am out of warranty and it's minimum 2k to fix. I have a 2019 vehicle parked that I can't get inspected and can't afford to fix because Subaru of America is trying to save money. Just a matter of time before this causes a tragic accident before they own up to recall.

The tcv thermostat control valve has failed which is a known issue and Subaru is very aware. The vehicle will ultimately believe it is overheating and shut itself down. This is a very well known incident and should be a proactive recall but instead Subaru insists on waiting for customers to fail and hope its outside of warranty so they can charge them $2k to replace a known faulty design and part.

I was driving my 2019 Subaru Forester on 5/16 and it was operating normally that morning with no visible warning lights. I got back into the car later and it started fine. While getting onto a local highway, accelerating to highway speeds, multiple warning lights including the check engine light turned on. I was subsequently unable to accelerate and needed to coast to a stop on the closest off ramp, fortunately avoiding an accident. After turning the vehicle off and back on again the check engine light was still illuminated and the car would only make short lurching movements. I needed to have the car towed to a local Subaru dealership (maita Subaru in sacramento, CA) and they diagnosed it as a problem with the engine's thermo control valve. This was replaced under warranty and the vehicle is now working normally. The dealership told me this is a known issue with 2019 Foresters and that they've repaired other vehicles under similar circumstances. Multiple other owners have detailed similar experiences on an online forum as well. There does not appear to be a recall but this is a serious safety issue.

According to an inspection from the Subaru dealership, my thermo control valve failed. Because of this, the check engine light came on and my safety "eyesight" feature (automatic breaking/collision prevention system) was disabled. This first occurred after starting my car after a visit to a park 2 miles away. When this occurred, I drove my car home and parked it until I could get it in to be inspected at the Subaru dealership who pinpointed the problem. Besides a quick check from autozone, this is the only representative that has inspective my vehicle.

The contact owns a 2019 Subaru Forester. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to auto zone, where it was diagnosed that the thermal control valve was faulty. The vehicle was then taken to the dealer, where the thermal control valve was replaced. The manufacturer was made aware of the failure. The contact related the failure to technical service bulletin: 09-80-21 (thermal control valve – design change) however, the vehicle was not covered under the TSB. The failure mileage was approximately 93,000.

Thermo control valve (tcv) is suspected. I am a member of 2019 Forester group on facebook and reports are quit common for these model year. The check engine light is on and rab system/eyesight is disabled.

* eyesight disabled and thermal control valve-p26a3 diagnostic code. Vehicle is available upon request. * eyesight immediately disabled and maintaining that all safety features are disabled. Safety features that are relied upon, disengaged, and aborted for literally a Subaru known engine issue (TSB #09-80-21) - that is safety at risk to everyone that owns a Subaru with this issue. * 2 independent services confirmed diagnostic- p26a3 *Subaru was requested to review when the vehicle was in for recall inspection. * no warning lamps, messages or any other symptoms of the problem prior to the failure. The warning lights and safety features disengaged all appeared at one time.

The contact owns a 2019 Subaru Forester. The contact stated while driving 20 mph, the check engine warning light illuminated. The contact took the vehicle to the local dealer, where it was diagnosed with needing the temperature control valve (tcv) to be replaced. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 67,000.

The contact owns a 2019 Subaru Forester. The contact stated that on multiple occasions while driving at undisclosed speeds, or while the vehicle was idling, the vehicle lost motive power; however, the engine remained running. The contact attempted to press the start/stop button to turn the vehicle off, but the vehicle failed to respond. The contact stated that several unknown warning lights were illuminated, and the turn signals failed to operate. The contact stated that she attempted to restart the vehicle several times however, after waiting for several minutes, the vehicle restarted. The vehicle was taken to the dealer however, the failure could not be duplicated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 50,000.

Check engine light seemed to put vehicle in "limp" mode, cancelling all onboard safety features, I. E. "eyesight", cruise control, vehicle dynamics control, blinking "s" upon bringing it to a repair shop, they informed me that the thermal value control needs to be replaced, despite having owned the car for only three years. This leads me to suspect either a faulty part or a design flaw.

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.

Thermo control valve went bad only after 4 years of owning a car. I do mostly highway driving put very little stress on the car. I think thermo control valve going bad just within 4 year. I suspect the parts to be faulty and it has some design flaw.

The Subaru Forester 2019 thermo control valve (tcv) fails. It is responsible for cabin temperature but also engine temperature and can result in overheating. There are numerous reports that this is a frequent problem and dealerships want to charge $1200+ to replace. It is certainly a design flaw and should be issued for recall. Mine is available for inspection and has been inspected by the dealership. It was first detected by a check engine light.

The engines shut down or stalled on me while driving completely. It did not accelerate when I was trying to move the car off the road. The engines sputtered / shaken , all the lights came up on the dash board, smokes started to come out of my engines. This problem is similar to the recent Subaru recall on the fuel pump. Please add 2019 Forester on your list of recalls. This is a serious and dangerous issue, I could have been killed if I was dring on the freeway. I was lucky it shut down on a little local street when I was dring slow , about 30 - 35 mpg. Imagine if this happened on the freeway, it could have created a chain reaction , and a lot more people will be involved, and deaths might be involved. Please add Subaru 2019 Forester sport on your list immediately because deaths involved. Thank you.

The thermo control valve has stopped working it causes the engine to overheat while drive. The windows fog up in the cold making it hard to because the defrost does not work yes by an independent service center no no the engine light came while I was drive.

Car stalls out sometimes when running while stopped. This is not the stop/start system. Also, driver door power window will sometimes raise and lower on its own.

The thermo control valve has failed and threw a check engine light. This disables the eye sight system and causes no heat or defrosters. There seems to be a huge backorder with no eta in sight for the replacement part. When this part fails there is no defrosters, no crash warning, no emergency braking. . . .

Tcv valve failed and as a result rab and eyesight were disabled. The tcv has a known defective design and there is a bulletin about it. Mc-10208664-0001 https://static. Nhtsa. Gov/odi/tsbs/2022/mc-10208664-0001. Pdf.

On 10/7/2022, all the warning lights came on and stayed on, even after tightening the fuel cap and replacing the battery. I brought the car to ocala Subaru this morning, and paid for a diagnostic that shows the thermal control valve needs replacement. Apparently this is now a common problem on this year and model Subaru. I was told that this is not covered under the powertrain warranty, even though it is part of the engine assembly, and is a very expensive repair, even though the car has only 43,669 miles on it. I was told the part is on national back order and that the car is okay to drive, but that most of the safety systems that have the lit warning lights are now disabled. This is the car my wife uses to transport our 6-year-old granddaughter to school and swim practice and events, as well as elsewhere, and I feel this has compromised their safety and warrants a recall.

Keep getting check engine light. Blue cold engine light stays on. Getting code p26a5 engine coolant bypass valve 'a' position sensor circuit range. Parts are unavailable at the dealer. They can’t give me a time frame when they become available.
