NHTSA Complaint #11585515 — 2019 SUBARU FORESTER

Engine failed without warning while driving on a busy highway on 4/20/2024. The engine suddenly stopped and tried to automatically restart itself only to immediately shut down, simultaneously dashboard lit up with multiple warning lights ( eyesight disabled, check engine light, RAB off, brake light etc). No power to the car with inability to accelerate. My husband driving the vehicle was able to maneuver the car over 2 lanes in heavy traffic to the rumble strip between 4 lane highway and a 2 lane acceleration entrance ramp. We came within seconds of being hit which could have been a very serious accident. Since the car had no power we weren't even able to get to the right shoulder. We had to sit in the vehicle over 2 1/2 hours waiting for a tow surrounded by high speed traffic on both sides. The cause of engine failure was a defective Thermo Control Valve, diagnostic code P26A6. Subaru recently issued an extended warranty in April for the TCV which is present in many of its vehicles. It should be a RECALL and not just an extension of the warranty since failure can be quite serious resulting in the engine completely shutting down. We had NO previous warning that the car was at risk for unexpected stopping. Car is well maintained with only 34,608 miles (2019 model) and had been in the shop the DAY before the incident getting routine car service. The service manager knew what the problem was by description before even performing the necessary interrogation for diagnostic codes. He was able to get the vehicle to start and drive it into the dealer repair shop by simply removing the TCV before starting. We were the 3rd vehicle in that day for replacement of TCV. He stated they replace 5-10 a week although most present with a check engine light and some with other warnings such as eyesight disabled. The factory original TCV has been replaced with a reportedly revised TCV. Risk of engine failure without warning as result of faulty TCV is putting lives at risk.
