While driving at highway speeds (70 mph) I encountered illumination of brake/ABS warning lights on the dash advising me that the safety brake/ABS/traction features on my car are non operational. Upon pulling over, I read a message displayed on the dash alerting me to take my car to the nearest Lexus dealer. Upon arrival at the Lexus dealership, I was advised by the service advisor that this is a common problem on this model and more likely then not the faulty brake actuator will need to be replaced. This was confirmed the following business day when I received a call from the service advisor confirming that the brake actuator has failed. Upon questioning the advisor of the cause, he once again acknowledged that this is a common problem and that Lexus has issued an updated part as a replacement. It concerns me that Lexus has not performed a voluntary recall on said brake actuator since this is a critical safety device and they (Lexus) acknowledge that there is defect to the original part by providing an "improved" brake actuator assembly. Furthermore, by performing a simple internet search I encountered numerous topics about identical issues as mine on the model/year (2007-2010 Lexus LS460). I would like to duly request that ntsb performs an inquiry with Lexus regarding brake actuator issues stated above.

I noticed that when I push the brakes I hear clicking noise and brakes acts heavily. I did a research on this issue and I found many complaints from Lexus owners. Some owners were lucky to have Lexus dealer replace the ABS actuator for them and other not. Lexus dealers told some LS460 owners that they changed the vendor of the ABS actuator due a malfunction error. Currently I'm concerned to drive the car on the highway as a fear to loose braking power. I tried to contact Lexus but they don't care.

Brakes making ticking noise when backing

I am experiencing a click or series of clicks when I depress the brake pedal. Based on accounts and research of other owners, this is a common problem with faulty brake actuators. It appears that Lexus is aware of the situation and I wanted to report this to the NHTSA database to potentially steer this towards a recall.

I drove my car over to pick my grandson up we went to the park, when I was taking him home the vsc code came on and said take care to dealer for service, engine light came on as well. I call and made an appointment immediately and they told me to leave the vehicle and they would run diagnostics see what was causing it. The next day they cleared the code called and told me to pick up. When I was leaving the same lights came on again (engine, vsc etc). Got out of the car and told service rep. That the same thing was happening again. I left the car over the weekend and they call and said it was a communication error and the computer wasn't communicating with the parking brake. I truly believe this is a safety issue and should be addressed by the manufacturer.

Lexus has a faulty brake actuator design. It's making clunking repetitive noises when brakes are depressed. Lexus knows of this faulty design but refuses to replace because they say it's not a safety issue. The noise alone will drive you crazy. Lexus of naperville, il wants to charge me $3000 to replace this component. If they do not rectify this problem I will never buy another Lexus again. Guarantee.
