2019 SUBARU ASCENT Forward Collision Avoidance Problems

Trying to pass an 18-wheeler on PA Turnpike. Weather 68-degrees, sunny day, no precipitation. When accelerating, the vehicle began shaking. There was a stutter in engine, shaking the vehicle. Suddenly a loud bang jolted the car and the Crash avoidance system applied breaks (I was the left passing lane, at a speed of 70 mph, with more than a dozen vehicles close behind). Emergency collision warning, EyeSight warning, check engine, RAB, and numerous dash error alterts illuminated. The parking brake turned on and off without human intervention (it's computer-controlled). The engine shut off and a multiple car fishtail began behind me. Fortunately, no one was hurt. I put the car in Neutral, lurched to the side of the road, and called OnStar. Calls to the dealer have not been returned. I drive elementary children to scouts and sporting events. I can't imagine the horror had they been harmed or worse.
