My 2013 Lexus Ls460 with ~50,000mi had its brake actuator failed (c1391 - leak in the accumulator). A month prior to code c1391 being triggered, the vehicle experienced inconsistent braking pressure with severe brake pedal modulation required to stop the vehicle. Traveling at speeds under 30 mph the vehicle would intermittently hesitate to stop. Moreover, a squawk noise was present when depressing the brake pedal. Code c1391 was triggered on 11/18/2021. Upon contacting Lexus dealers and national customer service (guest incident #211121-000001) to repair the part under warranty, Lexus denied warranty. Inquiry was also made for Lexus dealers and Lexus customer service as to the correct brake actuator part number required for replacement. Both Lexus dealers and national customer service provided the wrong/superseded replacement part number (I. E. , part 44050-50110). Below is the customer's research model Ls460 brake actuators: -per 2016 zlg warranty: 2007-2012 Ls460 came with part 44050-50090, 44050-50130 to be replaced by 04003-45450 actuator. -per 2016 lsb-0047-2013-2017 Ls460 came with part 44510-50070 and 44050-50110 to be replaced with the same model 44050-50110 actuator for brake squawk noise. -per 2019 lsb-0047-2007-2017 Ls460 came with part 44050-50110, 44050-50130, 44050-50150, 44050-50170, 44050-50090 to be replaced with 44050-50170 if repairs fail to remedy the brake squawk noise. It appears Lexus has attempted to revised the brake actuator various times to arrive at part 44050-50170, for which continues to fail. It also appears many superseded units are still being sold as replacements for failed actuators online through Lexus dealerships and Lexus authorized retailers. It must also be noted that a failing brake actuator (even prior to code c1391) will cause the brake booster pump to prematurely fail as the brake booster has to constantly pressurize the system causing it to overheat. Both repairs are urgent costing $3000-3500 each.

The contact owns a 2007 Lexus Ls460. The contact stated that while driving at various speeds, an abnormal tapping noise would emit from the brakes. As the failure persisted, the vehicle would drift upon depression of the brake pedal as "the pull over immediately, contact your local dealer," warning message and the abs warning light appeared on the instrument panel. The contact took the vehicle back to the independent mechanic where he purchased the vehicle but was offered no assistance. The contact then took the vehicle to a dealer where he was informed that the brake pads and rotors were aftermarket parts that caused the failure and needed to be replaced. The contact declined to the have the vehicle repaired; however, as the failure worsened, the contact had the vehicle towed back to the dealer where they diagnosed the vehicle with a defective lower control arm as well as the failure with the brake pads and rotors. The contact declined the repair again and had the vehicle towed to his sister's home. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 111,000.

From underneath the car barks every time break pedal is pressed at any speed. Constant beeping inside my car, couldn't figure what it was or where it was coming from. Bad brake booster and "actuator". Safety!!!.

Brake system makes , "bark" noise when stopping. Noise can actually be heard behind the instrument panel dash area inside the vehicle. Vehicle running and in motion. Any speed. Pretty much happens every day of driving. I have a concern for brake and vehicle safety when parked , vehicle running, no noise when brake pedal applied. Commom proble with this Lexus?.

I am having issues with my brake actuator and abs system. Lexus had a warranty campaign for this issue with the prior generation 07 to 10 Lexus Ls460 yet this issue persists with 2013 Ls460 . They are aware of this problem my car had almost no braking ability and it is unsafe to drive to add insult to injury the so called fix cost $8000. Other Lexus Ls460 owners have complained about this problem and have expressed their concerns in the Lexus forums and blogs these complaints are in the thousands.

Brake pedal on vehicle requires significant force to trigger brake lamps to turn on. In many instances, the vehicle can come to a complete stop before the brake lamps are triggered.

Experiencing both the dreaded brake actuator assembly issue as well as the very common mark levinson amplifier issue, on model # 0w480. Was in conversation with Lexus customer satisfaction and they are completely unwilling to step in and do the right thing in assisting me with either, or both, problems. I've owned this vehicle for all of 2 months, and although I understand that I bought it used, as-is with higher mileage, I think that since there was a recent warranty enhancement program issued by Lexus on the brake actuator assembly, and also that the failed amplifier is a very, very well-known issue, where the amplifier all of a sudden one day cuts out and all sound is replaced by an incessant chirping noise that's only stopped by pulling the wiring harness on the amp or a fuse, that Lexus should do the right thing by its loyal customers and replace free of charge. But they will not, because exactly like every other company in the entire world, they simply do not care about the customer or their experience. Sorry, but this is the only way I am able to view my experience.

Having problems with the brakes. When I press the bridal all the way down. There is a creeping noise coming from the brakes. Have seen numerous complaints of the same issue on Lexus vehicles. Many states it's the brake aculator.

The abs/brake/vsc/ light came on, making beeping noise and hard to brake.

I purchased this car in 2018 and it had less than 75,000 miles on it. I've recently noticed that whenever I press the brake pedal, there is a clicking/popping sound. I'm unsure what it is. I know that it shouldn't be happening. I've read on this site that it maybe the brake actuator. Is there a recall for this problem since it's been brought to Lexus/Toyota attention?.

As a result, the vehicle crashed into a side embankment, bounced back onto the freeway, turned 360 degrees, and crashed into the embankment again. The vehicle then bounced back a second time onto the freeway before it came to a full stop. Bystanders helped to coast the vehicle over to the side of the road. The air bags failed to deploy. The driver sustained neck and back injuries that did not require medical attention. The front passenger sustained a spinal fracture, eye socket fracture, and back injuries that required medical attention. The rear passenger sustained head injuries that did not require medical attention. A police report was filed. The vehicle was towed to the contact's residence.

The approximate failure mileage was 75,000.

Vehicle unsafe to drive after abs actuator malfuntions and notice that is unsafe to drive per codes from the computer specifically all brake malfunction lights and warnings come on ont the display warnings indicate the vehicle is unsafe to operate and to have it serviced immediately . . Called Lexus state they had a recall on it but will refuse to repair if lights came on after 2016.

Abs actuator and or brake accumulator defective. Recall needs to be extended for remaining vehicles to be safe. This vehicle as never taken in for the recall. After purchase and driving the vehicle for approx. 4 hours all brake malfunction lights and warnings came on. Warnings indicate the vehicle is unsafe to operate. I appreciate any feed back on this problem and thank you in advance. Daniel Ford concerned driver. There is an open recall for the fuel line for this vehicle as well.

I was driving home at 25mph (without my child) approaching an intersection, when the car in front of me makes a last minute lane change to turn at the intersection, I go to break and it doesn't break, the pedal reacts hard where it's always a soft compression, the dash lights up flashing the message "break malfunction" "check abs, check vsc, check brake system, not to drive vehicle due to system failure, contact deal immediately". I coast down the road and upon breaking again the whole car shakes making steering and especially turning very difficult. I take it 5mph the rest of the way and once home and parked, I try to restart the vehicle. When depressing the brake to activate the electric start, the break kicked back and the car would not start. I had the vehicle towed to the dealer it was purchased from. The dealer did confirm it was the break actuator assembly (l-sb-0178-09) that had been issued a special warranty (policy bulletin 16-01) with a 10 year term from purchase date. Unfortunately the issue had not been taken care of with the original owner and then became a problem 8 months after I made the purchase. . . Which is now out of the special warranty term. I am currently working to resolve the issue and hope Lexus will help cover the $2600 repair. More importantly I am hoping it becomes a recall because of the safety issue. I can't imagine what would of happened if I was on the freeway.

Brake caliber safety issue shouldn't have been a factory recall. I'm not happy whatsoever to have to pay out-of-pocket for something that Lexus knows about.

While driving the car, car warnings on my instrument panel began flashing stating "check abs", "check vsc", "check brake system", and "stop the vehicle in a safe place immediately. Contact a dealer".

Vehicle currently has 65k miles. Within last 1,000 miles, began noticing noises coming from brake actuator. Noise has become more noticeable. Today, on 12/15/2016, while driving, I was required to brake suddenly, and vehicle was not as responsive as needed. This almost caused an accident. I called the local Lexus dealership, and they are not aware of any current recalls - this needs to be looked into soon, before the failure of the brake actuator causes an accident.

While braking gradually, with the brake pedal in a steady position, the car lurches/pulses, the tires makes loud skidding sound then the car comes to a hard stop as though it has slammed into something. This has happened on multiple occasions at low speeds, where it feels like im pressing the brake and letting go, and pressing again, but in reality, the brakes are being pressed at a constant pressure. This is different than the abs feeling, as the brake pedal does not travel beneath my foot, and the release and grabbing of the brakes seem very slow. It happen the first time with about 50,000 miles, going about 25-30 mph. Then with 86,000, going about 5-7 mph.

The brakes have a chattering noise and feel through the pedal while stopped, when you release them. The car can be in park, and it still does it. It's a known problem, but Toyota is doing their best to avoid repairing it under the newly extended warranty on the "brake actuator". It's 100% repeatable, as many times as you like, if the engine is running and the brake pedal is pushed and released.
