There are 8 owner-reported driver assist & adas complaints for the 2019 Subaru Foresterin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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 not safe. I ended up having to have the car towed to the dealer. The dealer did fix the car, under warranty. However, twice I was caught on busy roads in a very dangerous situation. I am very glad that I was not injured, nor those that came to rescue me. But this should not have happened. The Technical Service Bulletin was issued on April of 2024 and I had no idea.
Improper glass installed by safelight adas unable to be calibrated
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.
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!
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.
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.
