NHTSA Complaint #11698030 — 2017 TOYOTA RAV4

My 2017 Toyota RAV4 XLE is experiencing unsafe behavior with the Adaptive Cruise Control (ACC). When driving around modest or slight turns, the ACC frequently loses tracking of the vehicle ahead and suddenly accelerates, then harshly brakes once it reacquires the vehicle. This creates a jerking motion and significantly reduces my confidence in the system. On one occasion while traveling approximately 45 miles per hour on a slight curve, the ACC began rapidly accelerating toward the vehicle in front of me as if no vehicle was there, forcing me to perform an emergency manual takeover and disengage the ACC to avoid a potential rear end collision. This issue is repeatable and appears to be related to how the ACC detects vehicles ahead while cornering. I am requesting that this behavior be investigated as a potential safety defect.
