NHTSA Complaint #11692504 — 2018 ACURA MDX

While operating the vehicle, multiple driver-assist warning indicators illuminated on the dashboard, including LKAS (Lane Keeping Assist System), ACC (Adaptive Cruise Control), and CMBS (Collision Mitigation Braking System). The systems either disengaged or functioned erratically during normal driving conditions. At times, the vehicle failed to maintain lane position, abruptly disengaged adaptive cruise control, or displayed collision alerts when no obstruction was present. Now it is constant. Safety Impact: The failure of the LKAS, ACC, and related systems can cause unexpected loss of vehicle assist functions, leading to abrupt speed changes or compromised lane control, increasing the risk of collision if not promptly corrected.
