2010 LEXUS HS Service Brakes Problems

Car has a brake malfunction. There was a recall issued for this model in 2013 for this year and model, yet they only included some VIN#'s in the recall when they know most if not all of these models have the problem. Recall: 13V235000 "Model year 2010 Lexus HS250h vehicles manufactured June 19, 2009, through October 9, 2009. Nitrogen gas from a component of the brake booster pump assembly could leak into the brake fluid." My car was manufactured during this period yet is still not included in the recall list. Lexus is absolutely responsible for a brake booster replacement, yet they refuse to accept responsibility. My car has always had odd braking on slick grounds, it has always skipped and slipped forward needing a larger breaking distance than a normal vehicle. Now my dash is lit up like a christmas tree due to a manufacturing malfunction. More VIN#'s need to be added to this Break recall. Please issue a safety investigation into this matter as more vehicles need to be included.

Pre Collision System light on dash, abs lights, traction lights etc Error Code C1391which requires a Brake Booster pump AND a Brake booster pump kit due to a MALFUNCTION which should be manufacturers responsibility. They launched a customer support program for a very short period (you had to have the error during this short time) and EXCLUDED all HS250h from the Secondary Coverage period by noting expiry if vehicle is over 10years which they were past that at the time of LAUNCHING THE CUSTOMER SUPPORT PROGRAM which is completely unethical and negligent to their customers. I was never notified of this program. This short time frame under the program leaves MOST customers with these vehicles at risk. A safety RECALL should've been done as this is a big safety issue. It is not safe to drive with a bad brake booster because it significantly compromises your vehicle's braking power, making it dangerous. A failing brake booster can cause a vacuum leak, which can lead to the engine stalling when you apply the brakes. Unreliable and worsening problem: The issue is likely to get worse over time, and you could be caught off guard by a complete failure, leaving you with dangerously unreliable brakes. Vehicle has been inspected by Lexus and Toyota, both quoting astronomical fees associated with Brake booster replacement due to malfunction. Lexus Customer Brand Support was of no help, just repeatedly stating that the program expired and that it is up to me if i want to pursue legal action because this needs to be resolved by lexus. There have been class action suits and accidents due to this malfunction and I will pursue legal action as this is complete negligence by Lexus.

there was a safety recall issued for this model for this year for this car. I took the car to someone and they told me there was a recall for this issue so I should take to the dealer. I took to the dealer in Chandler, they told me there was no open recalls. I called the Lexus customer service line, they told me to take the car to the place where they had originally done the recall work, at Bell Lexus. Even though they know this was from a recall they will not perform the work even though this is a known issue and safety recall on this car. this is the same combination as the recall and they will not even consider fixing it.

ABS Braking System Pump with an abnormal leak of ACC Press. Under recall # DLD for the same ABS Brake Booster Pump failure a Lexus dealer repaired the system under recall notice in 2013. The same issue happened again in 2025 an ABS Brake Booster Pump failure rendering the car unsafe to drive with a defective braking system, an ABS light and Brake light illuminated on the dashboard. The vehicle was taken to a local repair shop which informed me the vehicle was unsafe to drive. I contacted the dealer who stated the repair in 2013 was on warrantied for one year. I then called Lexus corporation under Case # 250212001465 and spoke to several Lexus corporate consumer advocates in their resolution department, who essentially stated Lexus cannot assist with a failed ABS Brake Booster component as it was once repaired and the responsibility to repair the ABS brake system pump falls on me the customer. I informed Lexus this was not a broken headlight, this is a safety issue, an abilty to stop the car braking issue for us and others on the road as the car is unsafe to drive at any speed. Therfore, I request the NTSB assistance to resolve this matter.

Lexus had a recall on certain 2010 HS250H cars for an issue where they have nitrogen gas leaking into brake fluid causing brake failure. My Vin number was not one of recalls however in August of 2023 they sent me a notice stating that if my car has this problem they will repair at no cost to me. Very expensive repair. That notice says they will repair until March 31 2024. It says if certain warning lights are not on , don't take it to get repaired. My car now has this problem and they are saying they won't repair it unless I pay for repair. I have 5 warning lights on and cruise control now won't work as well as they note that brakes could fell causing a collision. I can't afford the repair and I don't agree that they won't repair it. Under the recall there is no time limit and they would repair it today. To me they are verifying that my car was one that should be on recall since it's the same exact issue and they sent me letter verifying that my car was one with problem. Is there anything I can do?

The contact owns a 2010 Lexus HS-250h. The contact stated that the check engine warning light was illuminated. The contact stated that while depressing the brake pedal, the brake pump was continuously pumping brake fluid. The vehicle was taken to a certified mechanic who diagnosed that the braking system had malfunctioned, and there was an abnormal leaking of the adaptive cruise control pressure. The contact learned of NHTSA Campaign Number: 13V235000 (Service Brakes) which was related to the failure. The dealer was contacted and confirmed that the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 222,000.

I own a 2010 Lexus HS250H. the problem exists that every warning light associated with the braking, traction, and anti lock system is on. Anti-Lock Braking System (ABS), Traction Control System (TRAC), and Vehicle Stability Control System (VSC) The dealer said it was a faulty Brake de booster and said it was checked in 2010 and was fine. And to fix the system they need to replace the brake de-booster at a charge of $3000. Apparently, it is not fine, and requested them to comply with the recall and change the debooster, and they said no. Are they libel for the recall fix?

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

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.

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.

Mileage: 117,695

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.

Mileage: 99,990

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.
