NHTSA Complaint #11690047 — 2022 LEXUS ES

While the vehicle was parked and no one was pressing the brake pedal, the ABS actuator pump continued to run and made a constant buzzing/whirring noise. This suggests that the actuator is cycling excessively to maintain brake pressure. I am concerned this could eventually lead to loss of ABS function or reduced brake assist, increasing the risk of an accident. No dashboard warning lights are currently illuminated, but the problem happens repeatedly and can be reproduced. The vehicle has not yet been inspected by the dealer, but I am aware other Toyota/Lexus hybrid models have had similar brake actuator issues in the past.
