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.

2010 lexus 250hs brake actuator. Driving along a city street going 45 MPH. Slowing down to approach a stop light. Immediately after depressing brake pedal the red brake light and ABS light comes on. My pedal goes straight to the floor and I have no brakes and almost crashed my car into the rear end of another car. Diagnostic showed code c1391that ABS master cylinder needed repair. I paid for a car report and found three recalls regarding that problem, toyota/lexus never notified me about those. I just copy paste the report that I have paid to have information about the recalls.

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
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/
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
Tl* 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 the federal safety agency 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.
Brake booster not working a safety issue toyota will not take responsibility the same thing is happening with the prius they use the same system.
My brake booster fails while driving and there is a recall for other toyotas not for lexus hs250h have to pay out of package for repair. The rear light is LED and they burn out no replacement from lexus.
On january 27 2012 my lexus took off by itself brakes would not stop the car reported to lexus dealer they found nothing wrong on april 10 2012 while on vacation in florida if happened again this time more power hitting a brick wall and damaging the car that we had to sell it because we were afraid to drive it.
While applying the brakes, nearly 100% of the time when I hit a bump of any sort (small, medium or large), there is an apparent loss of breaking and the car actually lunges forward -- feels like acceleration -- and even pressing firmly on the break does not slow down the vehicle. This has occurred on several (probably about 10) occasions since I first got this car. Fortunately, it has never resulted in an accident, but I have come extremely close a few times. I do not feel safe in this car when it comes to braking. I never experienced anything like this on any vehicle. Especially with lexus.
While braking there is a sudden loss of brakes and simultaneous lurching or lunging forward of the car as if it is accelerating. It happens for a split second but it is very dangerous since something can be hit and/or it creates a very unsettling and unpredictable reaction from the driver and passengers. It is very unusual and I have never experienced anything like it. It has happened many times over the last two years, the last two times in feb. 2012. It happens during slippery conditions or when going over a bump.
The car had a recall to correct the problem of brake failure on uneven, bumpy pavement. Had problem at least half dozen times before the recall repair was made. It did not solve the problem. I have had the problem several times since, usually in monmouth county, most times near my home, but last time in long island freeway. The brakes do not slow down/stop vehicle for approximately 1 second, and then start to work. It is intermittent problem. I had lexus rep come to test my car yesterday, november 9, 2010. They were not able to simulate problem, but have advised they have been able to simulate problem on other vehicles of this model since the recall repair. They advised that even if they simulate the non-braking, this is considered "normal" based on the lexus engineers. I want a car that brakes every time. It is not safe vehicle.
Tl*the contact owns a 2010 lexus hs250. While driving approximately 65 MPH, the driver applied the brakes. The vehicle began to brake as normal before the brakes felt tighter and the vehicle suddenly lost control. When the vehicle lost control it began to slide and then began braking as normal again. The failure occurred whenever heavy pressure was applied to the brake pedal. The vehicle was taken to an authorized dealer where the contact was told the vehicle was functioning properly. The failure continued. The failure mileage was 3,000 and the current mileage was 9,500.
I have a lexus hs250h year 2010. When you go over a series of bumps or railroad tracks at about 40mph while hitting the brakes to slow up the brakes fail. Even with my foot still on the brake pedal the brakes fail and I have to release my foot off the brakes andpress down again. I have had the car back at 1,000 2,500 and 5,000 and complained about it each time and was told the first two times that it was fixed. Well the last time in when I told them again about it the dealer said when I was leaving and asked if they fixed the brakes he said "it is a characteristic of the hybird car to have the brakes react like that". Well it is not safe like that. Get one and try going fast over a series of holes or bumps or rough railroad tracks and put the brakes on just before you hit them and the brakes release even with your foot still on the brake pedal.
I was driving my lexus hs250 hybrid on a highway access road traveling about 30 miles per hour when a vehicle moved in front of me slammed on their brakes. When I fully engaged my brakes the car ahead of me was about 40 yards away. When I slammed on the brakes, the ABS system activated and began slowly trying to stop the vehicle. It did not matter how hard I pressed the brake pedal the ABS kept a gradual slowing. I missed the car in front of me by two inches. I took my car into the lexus dealer and they ran a full check of the ABS and indicated its working how its supposed to. The reported software fix had been accomplished on my vehicle a few months ago. I've read a lot of information since the incident regarding the hs250/prius brake problems and the reported software fix and can assure you that did not address the problem. No brake system should take that long to stop at that low of speed. The road surface was not highway smooth, but it was not bumpy nor was there excessive moisture on the road, whey toyota claims is a cause. Since the dealer service department could not duplicate the problem I was sent on my way.
Tl* the contact owns a 2010 lexus hs250 hybrid. The contact was driving approximately 1 MPH when he applied pressure to the brake pedal, the vehicle began to slide. The contact was able to gain control of the vehicle and continue to drive normally. The vehicle was taken to an authorized dealer where the technician was unable to duplicate the problem. The federal safety agency campaign id number 10v039000 (service brakes, air: antilock: control unit/module) recall repair was performed on the vehicle; however, the vehicle continued to experience the failure. The remedy repair did not correct the failure. The vehicle was taken to the authorized dealer on five occasions for the identical failure. The vehicle remained at the dealership for one week. The technician stated the failure was a manufacturers design. The failure mileage was 869.
Lexus hs-250h 2010 momentary brake failure.
Entering a freeway from a downgrade cloverleaf entrance ramp. Dealer used new car, 7,000.00 miles. Driving home from dealership after purchase. Weather was mixed rain and freezing rain. I applied the brakes to complete the last segment of the clockwise cloverleaf turn. Brakes locked. No anti-lock action occurred. Car slid into the left curb and bounced off to hit the right curb. Total front end undercarriage damage. Cost to repair, $14,000.00+. More than a month to get parts and repair at dealer preferred repair shop.
The vehicle won't stop. It was a very cold day, it had been snowing a bit and I was at an intersection. The car seemed to keep going and the ABS did not deploy either.
I have a new lexus hs hybrid and I have specifically noted problems with the brakes when going over bumps, potholes, etc. The brakes seem to 'skip a beat', or 'not catch' for a second after you go over a pothole and I noted this directly to lexus and in the survey forms I filled out for them.
This is to report a problem with braking system in lexus 250h 2010 model car. When I drive over a bump the car loses a braking power and it causes what seems like an acceleration forward. Luckily there were not any accidents yet as I keep sufficient distance, but it could lead to severe consequences.
I purchased a new 2010 lexus hs250h on october 31, 2009. I commute approximately 20 miles each way to my office in downtown denver, co. Approximately 2 months ago while traveling north on lincoln street and braking hard to slow for a left turn onto colfax with a green light, I experienced momentary brake failure and went into the intersection unable to slow or stop. The street in the far left turn lane has several large bumps and I initially attributed the problem to the car's suspension when I filled out a survey for lexus. Since that event, I have had two more similar problems at the same intersection. On february 5, I reported the issue to the lexus dealership where I purchased the car and provided them imformation similar to the above details. They are looking into the issue at this time. I believe that this is similar to the issues reported with the 2010 prius and should be included with that research.
Lexis hs250h 2010.....on 4 different ocasions the brakes fade and almost caused me to have a rear end accident. I informed lexus and they said there was nothing wrong. I have owned a hybrid car in the past and the brakes on that car worked as they should. This vehicle you can not tell if it will stop in time.
My car has lost braking/slipped 3 or 4 times in the same spot on my street where there is uneven payment. I drive the new lexus hs250h... It sounds very similar to the prius brake recall. I have had the car 2 months. After a couple of brake pressings, the brakes resume.
We own a lexus hs-250h that seems to have a problem with the braking system. On uneven or bumpy road surfaces when the brakes are applied they do not initially respond. It takes a second braking application for the stopping process to begin. This defect has occurred approximately 4 times since we purchased the car in september, 2009.
Approaching intersection using brake car accelerated on three separate incidences. 3,000 miles on car. All three incidences in last 500 miles.
When at a mid-speeds (typically 35 to 50 MPH) and one tries to brake on a rough, uneven or loose gravel surface, the car accelerates against the driver's braking. This is particularly problematic when making a turn from a bumpy or uneven road. The acceleration force overpowers the driver's braking and makes the turn difficult causing the driver potentially to overshoot the turn. This acceleration against braking has also occurred on straight road driving when one brakes from mid-speeds on uneven, bumpy or loose gravel roads. This event has occurred repeatedly in similar circumstances.
Not sure what happened but the car ran into a barrier pole while turning into the parking garage. The front bumper was damaged. I cannot tell if it was a problem with brake or not.
