Model Years Affected: 2007, 2008, 2009, 2010

Average Mileage: 58,034 mi (15,000 mi - 145,000 mi)


A clicking or knocking type sound may be noted from the brake actuator when applying the brakes lightly, or if the brake pedal is pressed while the vehicle is stopped. Our technicians tell us a revised brake actuator is available to correct this concern.

    Clicking and knocking at a hard stop, actuator or solonoid was first dx, now they say it is a $2300 fix!
    I took it in before the warranty expired and got a clean report, now 10000 miles later this problem.
    I thought these were dependable cars. My LS 430 was at 106000 WHEN i TRADED IT IN AND NEVER HAD the first problem.

    A knocking sound is heard from the brake control module/brake actuator when applying brakes, or if the pedal is pressed while the car is stopped. I have been told there was a service bulliten issued 12-2009. Unfortunately may vehicle is out of warranty and currently attempting to get Lexus to do whats right. I have been told the cost of the new revised actuator is approximately $3000.00

    Same here... But haven't taken it in for fear of what they might do to it. Also have the vibration problem. Only started when I switched tires from the Perelli's to the Michelin's.

    the pedal feels like i have 120,000 miles on the front rotors the car is driven on the highway most of the time i am shocked, my BMW first set of pads was at 75K, my GL Mercedes at 60K, how can this be?

    Actuator replaced. Noticed the beginning of the problem at 13,000 miles and told it was normal. Now at 40,000 miles starting to hear noise again when braking. In to dealership now.
