2010 Lexus HS250H Hybrid service brakes problems

“Complete loss of hydraulic brake pressure resulting in brake pedal traveling to the floor. Defect: Brake Actuator and Pump Assembly failure Risk: The vehicle has been deemed unsafe to drive by a certified Lexus technician and I was asked to sign a liability waiver to remove vehicle from dealership. Description: While driving my 2010 Lexus HS250h (90,729 miles) I experienced sudden and catastrophic failure of the braking system where the brake pedal traveled completely to the floor, significantly increasing stopping distance. A diagnostic at Lexus dealership confirmed a failed ABS brake actuator and pump assembly. The dealership stated the car is life-threatening unsafe to drive and required a signed liability waiver before I could tow it away. Despite this being a known defect previously addressed in Lexus support program 23LE04, the manufacturer has declined a goodwill repair for this safety critical component.”

“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…”

“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?”
