Multiple dash lights including "brake system failure, collision mitigation system problem, adaptive cruise control problem, road departure mitigation system problem, etc." RPMs effected, car does not shift into third gear. Safety of myself and others were at risk because the vehicle stalled then would not go over 20mph. Had this been a busy highway, lack of warning could cause a major collision. The vehicle was recently inspected and passed by Criswell Honda, Gaithersburg and purchased by me today. No dash lights were displayed. I drove less than 100 miles before the issue occurred. The vehicle is currently being towed back to Criswell Honda for diagnostics and repair (or I was told that is what they will be doing).

The vehicle's dash states the following are malfunctioning: Road Departure Mitigation System, Adaptive Cruise Control, Auto High Beam, Collision Mitigation System, and Lane Keeping Assist. The vehicle is available for inspection upon request. A few days prior to this message appearing on the dash, the car flashed and beeped that I needed to BRAKE when there wasn't anything in front of me while driving. The car automatically braked without me doing anything. There weren't any vehicles behind me in that specific moment. With how sudden the car braked, this could have caused a collision. This vehicle has been repaired by the dealership where it was purchased, for this exact issue. The first sign of sensors malfunctioning was in January 2022 (I purchased the vehicle in June 2021). I have taken the vehicle to the dealership for repairs 3 times in relation to sensor malfunction and for replacement of rear actuators, which is stated in the Service Repair Summaries. Since the last repair in 2023, the same problem has occurred once again. This latest incident has included the automatic braking without any objects in front of the vehicle. I have not driven the vehicle in two days due to this safety concern.
