2019 Subaru Forester Collision Avoidance 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.

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.

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!

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.

First problem was eyesight was not engaging. Had diagnostics run and they said there was no problem. That problem continued.
