Your lane-keeping assistance system failed to keep your vehicle on the road while driving on the highway, causing you to drift into a ditch. You were able to manually steer back, but you believe a deeper ditch could have caused a rollover. The problem appears to be that when your audio system is playing at normal volume, the warning chimes that alert you to take control aren't loud enough to hear over the music, so you don't get timely notice before the system disengages. This issue has happened multiple times over the past year.

Braking system sometimes is activated by a sign on the side of the road, by a tree if we are turning, or nothing at all. Nearly in 2 rear end collisions when the system activated incorrectly. We cannot drive into our garage with the system activated...brakes keep slamming on. The only safe way to operate this subaru is to manually turn it off every time we start the car. Subaru dealership states it cannot recalibrate the eyesight system as it does not have that ability. Dealership is in Corvallis oregon. Lane notification system also has issues in construction zones (it tries to steer the car into the water barriers marking the lane changes. At least the side warning system can be permanently disabled. We have filed many complaints with subaru to no avail. Promised return phone calls never happen, phone transfers to their technical department result in dropped calls. This system is dangergous!!!
