2019 SUBARU FORESTER Forward Collision Avoidance Warnings Problems

The contact owns a 2019 Subaru Forester. The contact stated that while driving approximately 70 MPH, the Forward Collision Avoidance system activated, and the vehicle immediately decelerated to 56 MPH. The failure was intermittent but had occurred several times over 5 years. The contact had to manually turn off the Forward Collision Avoidance system to avoid the failure. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was unknown.

While I was driving on a major road, the car appeared to sense an issue and automatically started to brake. While I was a road with 55mph drivers, my car was forcing me to stop. May warning light appeared; Eyesight Issue, Check Engine, Brake and many others. I was able to disengage the crash prevention manually and continue to drive. When I took it to my mechanic, he told me all the codes went to a Technical Service Bulletin for the Thermo Control Valve. He reset the codes and told me to take it to Subaru for an under warranty repair. Once I left the mechanic, I was travelling home and the car had the same issues, again while driving on a very busy road. This time I could not disengage the system, and I struggled to get the car over to the left shoulder. It was very narrow, and...

During severe stop/go, thick, holiday traffic on I-495 (DC Beltway), during daylight hours, once AGAIN (this has happened several times before), the auto engine shutoff feature catastrophically malfunctioned, turning the car off, and simultaneously, activated the entirety of the dashboard to flash on/off, causing nearly every indicator light to come on, and then had difficulty restarting. This has been brought to Subaru's attention multiple times and they essentially have washed their hands of it and stating since they can't duplicate it, it essentially must not be occurring and they cannot repair it.

I got in my vehicle after getting gas. I was on my way to Neosho, MO, hundreds of miles from home. Thes lights were all on and I couldn't get them to go off. I figured it was because my windshield was dirty. I turned my wipers on to find out one needed replaced. I paid $30 for 1 since I have an odd type of wipers and I had been to 3 auto stores to find it. The Eye Sight, brake, check engine, air bag, and lane assist lights never went off. Now they come on randomly and go off randomly. This causes all safety features to not work. No adaptive cruise control, nothing. I finally got them to go off somehow the day I came back home. I live nowhere near a Subaru dealer. It had no other effect on my vehicle as far as I could tell....

Improper glass installed by safelight adas unable to be calibrated

All of a sudden, the eyesight and collision prevention stopped working, the check engine light came on, the blue light thermostat indicator came on. We had no heat. The flashing "S" (sportsmode indicator) came on. We were driving on the highway and still over an hour from home. It was snowing, we could not adequately clear the windshield of fog so our visibility was severely compromised. We lost all Eye Sight capability which meant that we were vulnerable if there was ever a crash or an obstruction in the roadway.

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.

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...

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...

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...

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.

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.

First problem was eyesight was not engaging. Had diagnostics run and they said there was no problem. That problem continued. Second problem was when I was sitting at a red light. When the light turned green and I started to go, Eyesight engaged and totally shut the car off. It had to be placed in Park and restarted. Dealer said they have never heard of this. Internet says it's a problem. I had contacted Subaru headquarters after 1st incident. They paid for diagnostics, but would not respond after I contacted them to say it continued. Dealer and headquarters blew me off.

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...

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

While on freeway at night on 9/28/22 about 8pm several dashboard lights activated including check engine, eyesight assisted safety light, steering and safety controls disabled, all at once! I pulled over and called Subaru for assistance. Called AAA. AAA suggested I drive vehicle off freeway. I went to brothers and he noted car not overheated and drive short distance home. Car manuals did not explain so many warning lights. Drove car to Roseville Subaru next day and determined that engine part had failed to leave for repair. Dealer service agent Raj would not provide any details, strange? Went online and found Subaru Service Bulletin #09-80-21 dated 2/28/22 indicating thermo valve defective causing warning lights, and to replace. I felt unsafe as on freeway at risk at night and am elderly. Subaru bulletin shows part faulty as of June7,21 per s.bulletin. Why not recalled by now? Unsafe to drive this car...

My 2019 Subaru Forester experienced an unexpected (random) activation of the pre-collision avoidance automatic breaking feature. While driving on a major city road (dry, sunny, typical Arizona conditions) at approx 40-45 mph the system activated despite there being no obstacle (car or otherwise) anywhere near the vehicle. The nearest car was at least about half a mile ahead. The break force applied was the strongest I have experienced in 24 years of driving. This is not the first time I have experience this issue in this specific vehicle. A similar occurrence happened more than a year ago.

Windshield cracked around September 10 of 2021. Forward warning went off at times since crack. I had windshield replaced and new windshield cracked 4 months later. I must pay $500.00 deductible. Now the crack on new windshield is 3 weeks old and has spread to approximately 15 inches. Windshield must be replaced again. Forward safety now goes off at times as with previous windshield when it was cracked.

I was on a sharp incline at idle behind a line of cars, waiting for the light to turn green and my Subaru Forrester surged forward, out of my control, and hit the back of the vehicle in front of me, causing damage to my vehicle and the one in front of me. I questioned the Subaru service center regarding it and they did not have a means to report the incident to Subaru for investigation, but offered to do a service check on the transmission of the car. Coincidentally (or of uncertain significance), I had been waiting on a back ordered part from Subaru for a malfunctioning thermal control valve that caused a check engine light to be continually displayed on my dash, disabling some of the safety features of the vehicle. They assured me that the malfunctioning part would have nothing to do with any surging problems and...

WINDSHIELD CRACKED SOMETIME BETWEEN 2/16/21 AND 3/4/21. VEHICLE WAS PURCHASED AS PRE-OWNED CERTIFIED ON 2/13/21 FROM DEALERSHIP. CAME OUT TO GO TO WORK ON 3/4/21 AND FOUND LARGE CRACK ACROSS WINDSHIELD. I HAD NO INSTANCES OF OBJECTS HITTING WINDSHIELD WHILE DRIVING THAT WOULD HAVE CAUSED INITIAL CRACK. INTERNET SEARCH REVEALED NUMEROUS SUBARU OWNERS COMPLAINING OF DEFECTIVE WINDSHIELDS IN MODEL YEARS FROM 2017 - 2019. COST TO REPLACE WINDSHIELD AND RECALIBRATE EYESIGHT FEATURE EXPECTED TO COST IN EXCESS OF $1,000. SUBARU CUSTOMER SERVICE CONTACTED AND ADVISED TO TAKE VEHICLE TO DEALERSHIP TO DETERMINE IF THIS IS DUE TO MANUFACTURERS DEFECT. CASE #1-66770999440

MY CARS WINDSHIELD HAS CRACKED FROM THE BASE UP OVER 12 INCHES. THE CURIOUS THING ABOUT IT IS I HAVE NOT DRIVEN IT IN THREE WEEKS DUE TO FOOT SURGERY AND IT HAS BEEN PARKER. THERE ARE NO TREES OR POSSIBILITY OF DEBRIS NEARBY. I DIDN'T HAVE A CRACK BEFORE MY SURGERY, MY CAR HAD NOT BEEN DRIVEN NOR HAS IT BEEN TAMPERED WITH. I HAVE A CAMERA ON IT 24 HOURS A DAY THAT NOTIFIES ME IF ANYONE COMES NEAR. THE CRACK IS DEEP AND LONG AND SUBARU HAS BEEN REPORTED FOR THE SAFETY OF IT'S WINDSHIELDS BEING DEFECTIVE. SINCE I HAVEN'T DRIVEN ANYWHERE IT IS CONCERNING THAT MY WINDSHIELD HAS CRACKED SO BADLY.

THE CAR HAS 12600ISH MILES. THERE ARE NO ROCK CHIPS, ETC. THE WINDSHIELD CRACKED FOR NO APPARENT REASON. IT DIDN'T HAVE ANY WHEN WE PARKED LAST NIGHT AND NOW THERE IS A 6 INCH CRACK COMING FROM THE BOTTOM CENTER. THERE WERE NO INSTANCES OF ROCKS, DRIVING OVER BUMPS, ETC.THE CAR DIDN'T HAVE A CRACK WHEN WE PARKED IT LAST NIGHT AND ALL OF THE SUDDEN DOES TODAY.
