On 8/20/23 heading south on I-294 in Chicago : in center lane with cruise control on and no cars close in front of me when the car suddenly started a hard braking without warning. No orange warning to brake came on but engine warning light of left of dashboard was on. Immediately turned off cruise control. Car would not accelerate and came to a stop on the highway. Tried to start without success, then restarted and the car came on but in neutral. It had been placed in Park before shutting off. Car started and drove uneventfully back to Indianapolis. Took to Acura dealer and diagnostics were run showing that "position range" switch or sensor had been activated. Told it was safe to drive. We do not agree and are selling the car. Dealer, or service Dept was very lackadaisical about the incident. I will contact Acura corporate headquarters as well.
