2010 Lexus Hs

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.

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/

WHILE DRIVING SOUTH ON A THREE LANE ROADWAY, MY DAUGHTER AND I WERE INVOLVED IN A COLLISION. WHILE I WAS DRIVING, A MOTORIST WAS EXITING A FAST FOOD RESTAURANT PARKING LOT FROM THE RIGHT SIDE OF THE ROAD, AND SUDDENLY ACCELERATED ACROSS ONCOMING TRAFFIC (ASSUMING THE DRIVER WANTED TO MAKE A LEFT TURN) WITHOUT OBSERVING THE RIGHT OF WAY TO THE DRIVERS ON THE ROAD. THE VEHICLE HIT MY CAR ON THE FRONT PASSENGER SIDE WHERE MY CHILD WAS SITTING. THE DRIVERS' SIDE AIRBAGS DID DEPLOY, BUT THE PASSENGER SIDE AIRBAGS DID NOT DEPLOY. THE PASSENGER SIDE WAS HIT WITH THE FORCEFUL IMPACT FROM THE NEGLIGENT DRIVER. I DID NOT HEAR ANY VEHICLE WARNINGS PRIOR TO THE COLLISION. A POLICE REPORT WAS MADE FOR THIS INCIDENT.

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.

SAFETY CONNECT SYSTEM THAT REACHES OUT FOR HELP AUTOMATICALLY IN THE EVENT OF AN ACCIDENT WILL BE DISCONTINUED BY MOST TELEPHONE SERVICE PROVIDERS IN LATE OCTOBER 2022. AS A RESULT LEXUS WILL STOP SUPPORTING SAFETY CONNECT AND WILL NOT OFFER AN UPGRADE TO 5G SERVICE FOR A FEE. I THEREFORE HAVE A 30,000 VEHICLE THAT IS OTHERWISE PERFECT THAT I WILL HAVE TO REPLACE IF I WANT TO MAINTAIN THIS SAFETY FEATURE. I THINK NHTSA SHOULD EXTEND THE REQUIRED TIME VEHICLE MANUFACTURERS SHOULD HAVE TO MAINTAIN SAFETY FEATURES EVEN IN SITUATIONS SUCH AS THIS WHERE THE PHONE COMPANIES ARE PHASING OUT A TECHNOLOGY. A REASONABLE FEE WOULD BE ACCEPTED BY MOST CUSTOMERS.

I AM THE SECOND OWNER OF THIS LEXUS HS250 PURCHASED 7/2020 IT HAD A RECALLED HYBRID TRANSAXLE REPLACED 7/2018, BY THE PREVIOUS OWNER. HOWEVER ON 8/11/2020 UPON STARTING THE CAR AND DRIVING JUST 4000 THE HYBRID BATTERY FAILED AND NEEDS TO BE REPLACED. I HAVE READ THAT THE PREVIOUS RECALL IS TO BLAME FOR THE HYBRID BATTERY FAILING PREMATURELY AND SHORT CIRCUITING THIS BATTERY REPLACEMENT SHOULD ALSO BE COVERED BY THE MANUFACTURER.
