Open the full vehicle complaint log (all categories)While driving in the left lane on a three lane highway (about 70mph) the car's automatic braking system engaged. The car would not accelerate creating a very dangerous situation on a congested highway at night. Luckily, we are able to navigate to a brake down lane without a collision. The check engine light, Eyesight light and RAB light turned on. The car would not function normally and was towed to a Subaru dealer (Patrick Subaru, Shrewsbury MA). Diagnosis was a failure of the Engine Coolant Bypass Valve P26A6. Other failure codes were: P0087, P2004, P2005, B2806, B2C22. I was told this is a known problem in Subarus of certain years, but, instead of recalling, the company has extended the warranty on the malfunctioning part. This incident happened without any previous warning and caused a life threatening situation for us and those around us.
There are occasional times (perhaps once or twice a month) where the vehicle does not respond with the expected acceleration of a depression of the accelerator pedal. Specifically, the vehicle "lags" when I depress the accelerator pedal. While I have not experienced a dire situation or collision because of it, I believe it might cause other drivers to experience a safety incident: a driver might want to perform a fast maneuver with elevated risk but not receive the expected acceleration. For example, I was once making a U-Turn with traffic oncoming about 2,000 feet away. I needed to make the maneuver swiftly but my vehicle lagged. I would like to report this issue in case other owners of the Subaru Crosstrek Plug-In Hybrid are also experiencing.
