2021 Subaru Crosstrek Cruise Control Problems

While driving at 70 mph on a three-lane highway at night, your car's automatic emergency braking system suddenly engaged and the car refused to accelerate, creating a dangerous situation in heavy traffic. The check engine light, EyeSight warning light, and RAB (Rear Automatic Braking) light all turned on, and the car would not operate normally. The dealer diagnosed a failed Engine Coolant Bypass Valve, along with multiple other fault codes. Fixing this issue will likely require replacing the faulty coolant bypass valve and diagnosing why the related fault codes were triggered.

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.
