NHTSA Complaint #11472185 — 2018 HONDA ACCORD

Two times while driving on the highway at 75-80 mph with CMBS system on and utilizing ACC. Out of nowhere, vehicle drops speed, ACC OFF notice comes on and an alert stating Collision Mitigation Braking System Problem. See dealer pops up. . At this point, I have to quickly react to increase speed on gas pedal and avoid someone hitting me from behind. I am not able to re-engage the ACC the remainder of the travel. After turning off the vehicle, the CMBS resets and ACC is available again. This is not possible to do while driving on a highway. The second time it happened, I was changing lanes into the passing lane on left and I seriously could have been hit due to my speed deceleration. I took the vehicle straight to the dealer and the guy checking me in said they get a lot of those system errors. This is not reassuring! They ran a diagnostic, step by step the advisor said, only to say the system shows no issue. This is not acceptable to me as I do not feel safe driving. In addition, the lane keeping assist LKAS feature also malfunctions. When there are shadows on the road, my car wants to swerve and steer me incorrectly. My car also will display a giant orange BRAKE warning when nothing is in front of me. One time it braked so hard that my seatbelt locked up and everything on my passenger seat slid off the seat. Thankfully, nobody was immediately behind me because I could have been hit for the sudden and unanticipated braking.
