I have a 2010 HS 250h with 90,000 miles. Out of the blue, the brake actuator started activating every 10 seconds (and even runs for a while once car is shut off) and there is a noise coming from brake pedal area when depressed. Lexus had previously recalled some 2010 HS 250 cars for brake booster pump issues. My VIN was not part of the recall; I dreaded this day would come. Toyota/Lexus is well aware of the brake booster pump issues in their hybrids. Dealer confirmed the issue and now it will cost me $3500 to have a problem fixed that Lexus should have handled a long time ago. I've contacted Lexus corporate and they will not fix the car. I hope the NHTSA will look into all the complaints about this issue and 2010 HS 250h cars. Lexus needs to step up and issue another recall.

Initially, the ABS, BRAKE, and Anti-skid lights illuminated on the instrument panel and braking began to be spongier than normal. This condition continued for approximately 4 years. The brake system now has failed and braking is extremely slow. The car began beeping constantly while on with or without the engine running. This latest error took place while driving at approximately 55mph, soon after a car entered the highway (4 lanes) in front of me, I braked but the brakes did not actuate properly increasing the stopping time and distance. Luckily, I was able to move to the left-hand lane and avoid a collision. This occurred on February 13, 2022 AutoZone pulled the following codes: C1241, C1252-Hydro-booster pump motor malfunction, C1253-Hydro-booster pump motor relay malfunction, C1256-Accumulator low-pressure malfunction, C1311-Open circuit in main relay 1, and C1391-Abnormal leak of ACC PRESS (All except C1241 are related to the braking system) No one has inspected the component. I was able to locate NHTSA Recall Bulletin Reference #10V039000 (SERVICE BRAKES, AIR:ANITILOCK:CONTROL UNIT/MODULE) that references Lexus HS250h models manufactured up to February 2010, yet my VIN doesn't pull up this bulletin when searching the database even though it was manufactured in February of 2010.

The brake booster pump/accumulator has a diagnosed internal leak. It is identical to Toyota Safety Recall 13V-235 for Certain 2010 Model Year HS250h Vehicles. The exact failure described is what my Lexus HS 250h is experiencing and the DTC code is C1391, which FOUR separate shops have verified. The recall listed DTC C1246 and C1256, yet the condition is that there is an internal leak and one must replace the booster pump master assembly. They describe it as following, "The subject vehicles are equipped with brake pressure accumulators consisting of a metal plunger containing brake fluid encased in a metal housing. The plunger is designed with metal pleated bellows to allow for motion. Nitrogen gas is sealed between the plunger and housing. There is a possibility that a fatigue crack could develop in the bellows due to the vertical vibration of the plunger while driving. If this occurs, nitrogen gas could leak into the brake fluid and gradually cause the brake pedal stroke to become longer, resulting in decreased hydraulic pressure. Under certain circumstances, this condition could affect stopping distance and increase the risk of a crash." I have record they did try a repair for this at 17 miles, before purchase, but it clearly DID NOT remedy the situation. After 80,000 miles with a gently driven car they should be required to :Replace the brake booster pump assembly (accumulator) AND the brake booster assembly. The remedy described in the recall information. Out of three repair shops, three have indicated that they cannot make the repair due to Lexus parts or warranty. It is at a Lexus repair presently.

So I just got this Lexus 2 days ago and I notice that if I have to brake suddenly, the car rolls forward for like a extra 3 seconds..you can feel when the brakes lock up and make the car slide forward, and you can also hear it as well..this is super dangerous and needs to be fixed

- Norfolk, VA, USA

While driving anytime I attempt to slow the vehicle the brakes do not work as it should the car continue to roll forward for a few seconds before it completely stops. ABS and traction control lights are on. My mechanic inspected the vehicle and advised that brake booster pump needs to be replaced and said there is a safety recall for this faulty part. I took my car to Lexus but they refused to fix the recall as my VIN is not listed in effected vehicles VIN list. Please help/

- Celina, TX, USA

Anytime I ride over a bumpy patch on a road on a street and then attempt to slow the vehicle, the brakes do not appear to work as one would expect. The car continues to roll forward for a few seconds prior to coming to a complete stop. This is extremely unnerving. To date, this has not resulted in an accident, but if not addressed it could lead to potential damages.

Brake booster pump went other vins same make model and year were recalled for this but not my VIN 4K job

The contact owns a 2010 Lexus Hs. The contact stated that while driving at 60 mph, the brake pedal was depressed however, braked ceased. The contact stated that the ABS, hybrid brake assembly, traction control warning lights were illuminated. The ignition was cycled to the off and on position however, the failure persisted. The vehicle was taken to (sewell Buick GMC of dallas 7474 lemmon ave, dallas, tx 75209 (214) 350-8000) where it was determined that the brake booster pump failed and needed to be replaced. The repair was still pending. The contact mentioned NHTSA campaign number: 13V235000 (service brakes) as a possible solution to the failure. The manufacturer was contacted and informed of the failure. The failure mileage was approximately 90,000.

On 8/16/19, I was leaving for work, and went to reverse my vehicle out of garage, down inclined driveway, found out that the brakes were completely out accompanied by warning beeping rapidly. The power steering also locked up. I was able to push emergency brake, which did stop the vehicle, I put in car in drive and went forward into garage and pushed/locked emergency brake again to store vehicle in garage on flat surface. Car was towed to local Toyota (Lexus certified) service shop. Diagnostic showed that ABS master cylinder needed repair, once repaired they then tell me the booster pump also needed repair. A simple google search revealed that in 2013 these exact parts were recalled on this same year/make/model however my VIN was excluded from this recall. It is believed that these parts are defected and should have been included in this recall initially. It simply cannot be a coincidence that these parts for the 2010 Lexus 250 H were identified as defective, along with 7 other recalls for my VIN alone. The previous day I had taken a trip 2 hours away, and back home. Had I been driving when this happened the results could have been deadly.
