Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“I have a 2015 Acura RLX equipped with precision all wheel steer(PAWS). According to Acura, PAWS allows the rear wheels to move independently of the front wheels for better control and handling. The system often malfunctions and moves the vehicle in a path other than what is intended based on my steering wheel input. It is very dangerous as I do not know when the system will malfunction and I have to quickly adjust the steering wheel to correct the PAWS malfunctioning. I have brought this to the attention of my local Acura dealer and American Honda. I now understand there is a known defect with the PAWS systems but Honda does not deem this a safety issue. There is a national backorder to have the appropriate part(s) in to remedy the issue. I do not feel safe driving the vehicle due to it's unpredictable nature and risk of causing a collision.”

The manufacturer was contacted and stated that the vehicle could not be repaired under Technical Service Bulletin: 13-041 because the vehicle was over the mileage. The failure mileage was 63,000.
