2022 Subaru Crosstrek

I was driving on the highway in stop-and-go traffic when suddenly I found myself depressing the brake pedal to the floor and the car would not stop. Additionally, the eyesight function that prevents forward collisions did not alert for obstruction or stop the vehicle. I was able to put the vehicle in park and then tried to reengage the vehicle, but the brakes failed to respond. I was in the middle lane of a major highway. My vehicle could have harmed someone else, in addition to myself, and I was also at risk by being stopped in the middle of traffic. I could have died, had I been traveling at actual highways speed. No lights or warnings were on in the vehicle before, during, or after the incident. As of now, the dealership has been unable to replicate the issue, thought they still have the vehicle. They have not been able to identify the cause of the issue, but have also been unwilling to put the tests they have done in writing for me at this point. At this point, I have little confidence in my vehicle, despite it being a 2022 with low miles. I am terrified that this intermittent issue could happen again. The week prior, I had an experience where the acceleration and braking were not functioning as expected, but I had just pulled out of a parked position and this resolved after putting the vehicle in park and reengaging the vehicle.

I was travelling down a 3-lane road wherein another vehicle in front of me, several car lengths away, merged into the middle lane to turn left. The turning vehicle approached the intersection and was stopped several seconds waiting for opposite traffic to clear to make their turn. As I proceeded through the intersection at 55MPH, the eyesight technology must have falsely locked on the vehicle in the turn lane and applied the automatic emergency braking. This resulted in a sudden skidding and a near miss rear-end collision from a vehicle behind me. I was able to apply the gas and avoid being rear-ended. I immediately disarmed the pre collision braking, called Subaru, and gave them an ear-full. they recommended having the eyesight re-calibrated.

When starting the vehicle in a narrow area, the reverse automatic braking will sometimes activate. This causes the anti-lock brake system to actuate while the car is backing up making a rapid clicking noise. After backing up approximately 6-8 feet, the vehicle will stall, the steering wheel will lock, and all warning dash lights such as "check engine" will be on. Air conditioning codes are triggered U0401 (confirmed - invalid data received from ECM/PCM "A"), and U0416 (Invalid Data Received from Vehicle Dynamics Control Module). Powering off the vehicle for a minute or two and starting the vehicle will return normal operation. This is a safety hazard if the car stalls when backing out from a driveway into a busy intersection. The car will also stall by locking the steering wheel and showing check engine and other errors on the dash, as well as activating the U0401 + U0416 codes when starting the vehicle (push button + brake), and then rapidly shifting out of park, and then using the accelerator. When this occurs, the hybrid system will not start, and the engine will not turn over. No power is transferred to the transmission.
