2019 Subaru Forester complaints

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.

The original battery does not support the CAN system and replacing the battery does resolve the issue. The system will shut off while stopped at a light to save fuel, and turn back on when you press on the brake or the gas. There is an error where the vehicle will try to start itself when you’re not even cranking it. This can be dangerous if the car shuts off at a light and won’t turn back on because the feature drains the battery. This needs to be a recall as Subaru is aware of the issue and implemented a new battery for the vehicles and want to charge double. Why should the consumer pay for something that the company is aware is a problem? And came up with a solution to the problem, but is trying to profit off of it instead of fixing their mistake?

The Eyesight feature went out and the heater went out and I took the car to a mechanic and he said it had a faulty thermo control valve that needs replacement.

I started my vehicle and the check engine light came on. In addition, my eye sight turned off and the letter S started blinking. I also had clicking noises when I turned the vehicle off. I read some forums and this is a thermo control valve problem that happens to many Subarus in 2019-2021 range. As I took the vehicle to check the codes, the heater did not work and the cold engine light kept coming on. The codes read P26A3. Other reports are: NHTSA 11490232; 12479843; 11511658; 11490977; 11479843; and many others. Apparently Subaru is aware this valve and has come out with a new replacement that costs a high dollar amount to change out.

On November 30th around 5:30 PM on [XXX] my wife struck and killed a 6 point buck. Thankfully a SC Highway officer was coming in the opposite direction saw the accident and aided my wife in getting out of the car as he had seen a fire in the engine compartment area. Shortly thereafter the car exploded and was engulfed in flames and totally destroyed. Neither the patrol officer nor the tow operator can remember an auto fire resulting from striking a deer.

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.

Defective/failed thermal control valve. Valve failed while I was driving, resulting in safety systems (e.g., lane keep assist, pre-collision braking). Looking this up, this is a known issue to Subaru.

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.

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.

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.

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 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!

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.

Thermo Control Valve went bad causing car to have no heat in the cold can’t use the defroster for windshield and no safety features Subaru knows about issue but not recalling it leaving us the high service payment

4 days ago my Check Engine light came on. In my car, when this happens, it disables all Eyesight features - collision warning, lane departure warning, etc. Work hours being what they are, I drove home that night and back to work the next day with it on. I managed to get it scanned when it popped a code for the Coolant Bypass Valve. Searching that code online lead me to DOZENS AND DOZENS of forums, posts, stories of the same code popping up on other 2019-2020 Subaru's. They all had to take it in for a hefty repair. It also led me to a Service Bulletin issued last year, which showed that Subaru had rebuilt the TCV so it could withstand corrosion, unlike the previous version. So naturally I took it into my local dealership to have it looked at, and sure enough - the TCV needed to be replaced. WHY HASN"T THIS PART BEEN RECALLED YET??? Given there is no thermostat on my cars dash, I would have no clue whether my car was overheating due to this faulty valve, until its too late. It seems like this is a big potential safety issue that Subaru needs to address, and someone needs to force their hand.

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

Check engine light is on and the heater control valve needs to be replaced. This part is on back order because so many vehicles need to have this replaced and it turns off all the safety features of the vehicle. This is unsafe, faulty and putting loyal Subaru drivers in a vulnerable position. This part needs to be a manufacturing recall as to replace out of pocket is close to $2,000 and only effects the AC but impairs the safety of the driver.

I came out to my parked vehicle to find a large crack on the windshield.

The contact owns a 2019 Subaru Forester. The contact stated while driving 60 MPH in a thunderstorm, the vehicle lost motive power inadvertently. The check engine, the Vehicle Dynamic Control, and the Eyesight Driver Assist system warning lights were illuminated. The contact was able to pull to the side of the road. The contact stated that the engine continued running, and the instrument panel functions were operable; however, the vehicle failed to respond upon depressing the accelerator pedal. The vehicle was towed to the local dealer, and the vehicle operated as needed. The dealer test-drove the vehicle but could not determine the cause of the failure. The contact stated that she picked up the vehicle; however, the failure recurred while driving. The vehicle was taken back to the dealer, and the dealer diagnosed that water was leaking out of the thermal control valve and onto the electric wiring. The vehicle was repaired under Warranty. The manufacturer was notified of the failure. The failure mileage was approximately 16,600.

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.

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

Car would not restart after engine turned off multiple times at intersections. All warning lights came on. Had to turn off vehicle completely and restart. Very dangerous. Required new battery

The contact owns a 2019 Subaru Forester. The contact stated that while stopping, the contact went to park in a parking lot and the vehicle had launched forward while the foot was still on the brake pedal which caused the contact to crash into a tree. The air bags did not deploy. The vehicle was going 1 MPH. No warning light was illuminated. A police report was filed. The vehicle was towed to a dealership. The vehicle had not been diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and advised the contact to tow her vehicle to the nearest dealership for diagnosis. The failure mileage was approximately 22,000. The VIN was not available.

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.

When driving, ALL lights on the dash went on and vehicle safety features did not work- no cruise control, automatic breaking, automatic headlight adjustments, etc. We were over 500 miles from home and had the oil changed but it did not fix the problem. Had $72,000 miles on it, 4 years old. We had to drive home that distance to get it repaired over a 2-3 day period. No safety features were enabled as we drove. Thermo Control Valve was deemed faulty and replaced. Seeing after the fact that the TSB was issued without any VIN numbers: [XXX] , I believe it should include our VIN number and be recalled and the replacement paid for.

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?

The visor will not stay in place and drops into my visibility while driving, blocking partial view of the road. Subaru has had this issue for years and has not fixed the issue with their visors.

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.

We were driving our vehicle westbound on U.S. Route 24, between Fairbury, IL and Chenoa, IL on Saturday, July 15, 2023 around 7:00 PM. We were travelling at approximately 55 to 60 mph when the brakes engaged suddenly and brought us to an almost immediate stop. This happened so quickly that it destroyed out transmission, cv joints and brakes. Had we not had out seat belts on, I feel certain that we would have been ejected. If a vehicle had ben behind us, I have no doubt that it would have collided with us. Immediately following the incident, the vehicle, which was now immobile, displayed the Eyesight warning on the instrument panel.

As a result of code P26A3 (engine coolant bypass valve), the cars Eye Sight system is turned off as well as lane departure, reverse automatic braking, and pre-collision braking system. While code P26A3 may in fact refer to a serious problem with then engine, there is no reason why a safety system should be shut off!

Sun roof malfunction. Would not open. Once open, went on highway and had to close it. This was distracting to me, driver, and put us all at risk for no weather protection or debris on highway. The sunroof malfunctioned again by not responded and would not close. No warning for any errors. Has not been inspected by insurance. It is available for inspection. Online forums show multiple people are having this issue!

My thermo control valve went out while I was on the highway. My car lost power and all safety features. It’s been replaced but should be a recall.

All side windows and the sun roof have become scratched. This vehicle is garaged, has 28,000 miles and never goes off road. The scratches extend into the door gasket area thus reaching to very top of the glass. Scratching of the windshield and rear window do not show this. We use a touchless auto wash. The paint is near flawless. There are no such scratches. I believe the glass is defective. We also own a 2015 Subaru Forester. it does go into dirt and grit. The side windows have no such tendency to scratch.

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

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.

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

Vehicle was parked in a private single-home garage near Houston, TX. While parked overnight the windshield cracked spontaneously. Crack is ~18 inches long and goes to the bottom edge of the glass around the middle of the windshield.

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.

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.

Was driving in the right-hand lane on the interstate with the cruise control set, went to change lanes as I was approaching a slower moving semi truck going up an incline. Cruise control deactivated with no inputs from myself. Vehicle began to decelerate. Looked at instrument cluster, the Check Engine Light was on along with Eye Sight Off symbol. Additional symbols for forward collision avoidance and rear active braking were also on. No warning signs were present prior to the cruise control turning off. The unexpected loss of power increases the risk of collision while traveling on the highway. Vehicle was taken a Subaru dealer, diagnosed with code P2682, Coolant Bypass valve performance, with a recommendation to replace the coolant bypass valve.

Automatic Rear lift gate will not raise (but does unlatch); the lift gate cannot be raised manually after latch is released. One can only open it about 6 inches until there is heavy resistance- like the strut has seized or a sensor has triggered a brake. Now, the rear gate cannot be opened in an emergency.

On June 20, 2023, the "check engine" light came on my 2019 Subaru Forester and "Eyesight" flashed on my dashboard as disabled. I immediately went to my mechanic and he ran a diagnostic which showed the following: "P26A3 - Engine Coolant Bypass Valve." My car has 75,000 miles and is out of warranty for the powertrain. In reviewing online forums, this problem is a recurring one that is affecting many Subaru owners. The cost is $1,200 to $1,500 to fix. I believe this should be a recall issue. Other drivers have noted sudden engine shutoff but I have not experienced that yet. The car is currently in the shop. Subaru knows this is a problem.

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.

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.

On 6-11-23, while parked in a private driveway, the front windshield of our 2019 Subaru Forester spontaneously cracked. This 20-inch crack ran diagonally from the upper left corner down toward the center of the dashboard. We are not aware of any impact that may have caused such a crack. The day was overcast, drizzle rain, ambient temperature was about 66 degrees F.
