2007 Lexus RX: ABS light or ABS activating

Filed Apr 20, 2026 · Brakes · GA

I am reporting a serious and potentially dangerous braking issue with my 2007 Lexus RX400h. The vehicle currently has approximately 126,296 miles. While driving, the vehicle emits a continuous and intermittent warning beeping sound. At the same time, the braking system becomes unreliable. The brake pedal becomes extremely difficult to press, requiring excessive force, and the vehicle does not respond consistently when braking. In addition, there are instances where the vehicle appears to brake unpredictably or inconsistently, which creates a significant safety hazard for myself, passengers, and other drivers on the road. Based on my research, this issue appears to be related to a known defect involving the ABS brake actuator assembly. Lexus previously issued a warranty enhancement program for this component due to internal malfunctions that affect brake pressure and system performance. However, this issue was not issued as a formal recall tied to VIN eligibility. Despite my vehicle being under 150,000 miles, I have been informed that I may be outside the time-based warranty window, and no active recall is listed for my VIN. This defect directly impacts the braking system, which is a critical safety component. Failures in the brake actuator can lead to improper brake pressure, reduced stopping ability, and increased risk of a crash. Given the safety implications and known history of this defect, I believe this issue warrants further investigation and potential recall consideration. I am submitting this complaint to request that the federal safety agency review this matter for safety risk and determine whether broader action is necessary to protect consumers.

Hydraulic brake booster pump abs actuator has been on a service bulletin around 2015 with a definitive timetable. I have had numerous notifications with warning lights that are indicative of the booster pump failure for more than 10 years and every time I bring it to the Lexus dealer they said it is my battery. They replace the battery and reset the computer and it repeats itself over and over. My main concern as this should have been a recall and not a service bulletin; an abs brake failure is a significant defect with possible fatal outcome. The problem has been well documented with numerous Lexus and Toyota customers hybrid vehicles going back to 2005. My vehicle is 2007 Lexus RX 400h with 78,000 miles. I am afraid to drive the vehicle with the issue unresolved.

Car has been making a clicking noise during stops for a year. I chalked it up to something unimportant. On 2/20/21, the 'check avs,' 'check ABS,' and 'check brake system' lights all came on, and car lurched while backing out of my driveway. I was driving my wife and daughter at the time. Brought lexus to my local mechanic on 2/22/21. After several days, mechanic returned the car to me, saying he could hear the clicking and, according to his research, it could be the brake actuator given lexus had done a warranty extension on this part in 2016. He told me this repair would cost in the thousands of dollars, and advised me to contact lexus. Spoke with lexus brand manager on 2/25 who told me about warranty extension zlg for actuators in 2016, and told me that in order for lexus to ascertain whether or not the car was experiencing an actuator failure, it must be inspected by a lexus service center. Because I was told about the specific extension and asked to take it to lexus to diagnose the issue, I assumed lexus would cover the repair cost. I took the car to lexus santa monica on 3/2/21 and was notified that the problem was related to the brake actuator, and that the cost to repair would be $3000 plus tax. I relayed to lexus sm what I was told by lexus corporate, and lexus sm told me they would call lexus corporate and see what they had to say about warranty extension 'zlg.' ultimately, lexus would not cover cost because the part was outside the extended warranty. I spoke with another lexus case manager about why a warranty extension was offered as opposed to a recall, and he said I should lodge a complaint with the federal safety agency. I also spoke with his supervisor, who said lexus would never pay for a part outside a warranty, even a faulty part given an extended warranty. Nobody in the lexus chain of command can tell me if the car is safe to drive. I will support class action suit.

The lights all came on ABS system came on stabilizer air bag took to lexus they diagnosed the problem as the brake actuator I research and found that on lexus club this is a big problem with my year and other years they acknowledge this by giving an extended warranty. But fall short to assist with after. There is many complaints I researched there is also a noise that is related to this problem the noise comes from the actuator, but being unfamiliar with the car normal features I failed to identify the problem I have heard this noise for a very long time I have always felt this pulse but thought it was normal I owned this vehicle now for 5 years. I thought the noise was the hydraulic system lowing the vehicle air down like my navigator did but that was the noise of the actuator going out. The brakes always felt like they had a delay or hit hard like a jerk just thought this was caused by sensitivity. It upsets me that lexus is and has been aware of this problem and never informed me and the problem just got worse the brake system is so vital why would they not after they realized this is a problem I had the warranty provider whom extended this warranty on this part but neither informed me even though both had my current information. Its a problem that lexus and its mother toyota know of and failed to make the problem right. If there is a problem and they recognize it why not make it right! Is my safety not important to lexus and toyota? #toyota # lexus #actulator #safety

The vsc failure, check hybrid system and ABS break system lights came on while driving the car on the street. Aside from being scary, it was difficult to drive the car and the breaking system felt spongy making it difficult to stop the car. The car is not turning on and all the lights on the dash are on. I replaced the battery. Yet the car does not turn on and the dashboard lights stay on. This is a serious safety issue that must be addressed by lexus.
