2026 Subaru Solterra

Malfunction of the lane keeping assistance - I have had two incidents, where the second has resulted in damage to the vehicle. First incident, lane assist (passive) system jerked me off of an exit lane into the rumble strips before I could correct. (no damage done) This was approx. Mid-late January, and unknown conditions. I didn't think to report it until I was prompted by the Subaru Maintenance facility after incident #2. Second incident - active lane keeping assist was on (with adaptive cruise control) for my own testing on this new car. I was at low speeds, at ~6 am. The vehicle suddenly jerked hard to the right and collided with/drove over a curb at speed. It quickly displayed a warning on the driver cluster and short audible warning beeps but I did not see what it was because it was so fast. The car immediately corrected back into the lane before I could even react to the collision. Important context: This was on a concrete material road that was newly repaved (summer 2025) with road lines that were painted at the same time. It was also under winter conditions, not actively snowing, but there was lingering salt residue/coloration on the road surface as well as large snow banks along the grass strips due to plowing. The snow bank in the area was approx. 3 ft high at the location the car collided with the curb. There was also lingering salt and dried snow-sludge on the car that could have had an impact on the sensors. I did not, however, have any sensor obstruction warning. The vehicle was taken to the Subaru dealer for service, was determined to be out of alignment and fixed as a warranty request. The vehicle is available for inspection, however this was clearly a software failure and not a component failure, and the damage has been repaired. To my knowledge, the dealer service center did not attempt to reproduce the issue.
