2019 Lexus RX350 Forward collision avoidance Problems

“On a recent 2500 mile trip on 3 separate occasions while on interstate hiways and passing a vehicle the emergency braking system engaged automatically with warning lights and buzzers going off. This occurred with no other vehicles anywhere around for a quarter mile or more. On one occasion it occurred while driving in the right lane and with no vehicles in sight. Lexus special tech inspected the vehicle and had some calibrations performed but they will not tell me what they found in data captured by the vehicle computer or what actions they took and why they think the vehicle is safe to drive.”

“The contact owns a 2019 Lexus RX350. While driving with the adaptive cruise control activated and set at 72 MPH, the driver reduced the speed to approximately 60 MPH when switching lanes. After releasing the accelerator pedal, the vehicle continued to accelerate past the set cruise control speed of 72 MPH and continued to accelerate to approximately 80 MPH. After deactivating the cruise control feature, the vehicle continued to accelerate and the rpms increased before the speed eventually was reduced. The cause of the failure was not determined. …”
