The brake accumulator loosing pressure for the brake booster and abs, the actuator will buzz every few seconds trying to keep pressure in the braking system to a safe operating level of gas pressure. It isn't holding pressure due to this leak in the actuator. This is a very serious issue which endangers the lives of others due this brake failure is not being fully addressed. There is not much stopping distances after this suddenly occurs. In the process, the abs, traction control, brake, a yellow exclamation mark, lights suddenly all come on the dash at once and the brake feels like a sponge very suddenly, and the car has little to no brakes. This can lead to a major accident. Toyota/ Lexus have an extended warranty that expires in at a 10 year mark or 150K miles but several complaints of this failure has been just after that time usually with in a few months and come at a high cost of repair almost $3-4K, fortunately I searched the internet for the warranty info and my vehicle is just under the warranty period by a few days and couple miles but the amount of people who currently drive these Toyota/Lexus models that may experience this failure is pretty high

Defective Brake Actuator and Safety Concerns in 2014 Lexus CT200h I am writing to express my deep concern and disappointment regarding a critical safety issue with my 2014 Lexus CT200h. I have recently discovered that the brake actuator in my vehicle is defective, potentially compromising my safety and the safety of others on the road. Details of the Issue: I have experienced all of my brake warning lights are all lit up. I would have to step on my brake 5 times as hard to stop my car. This issue poses a significant safety risk. From what I understand from this problem, the brake system can stop working at any moment. Upon further research, I have discovered that this problem appears to be a known issue with the Lexus CT200h and similar Prius models, as they share the same brake actuator components. Numerous complaints and reports have been documented online and with the National Highway Traffic Safety Administration (NHTSA). Request for Action: I urge you to take immediate action to address this critical safety concern. I request that you: Thoroughly investigate the issue with the brake actuator in my vehicle and perform any necessary repairs to ensure its proper functioning. Cover the cost of all repairs associated with this defect, as it appears to be a systemic issue rather than an isolated incident. Provide a clear explanation for why this known defect was not addressed proactively and what steps are being taken to prevent similar issues in the future. I am deeply concerned about the potential safety implications of this malfunction and believe that Lexus has a responsibility to prioritize the safety of its customers. I expect a prompt and comprehensive response to this complaint. Additional Information: I have attached any relevant documentation regarding this known problem

As stated above, I own and maintain a 2014 Lexus Ct200H. My issue is specifically with the factory ABS and brake booster pump that recently failed due to an internal leak of the pump causing the brakes to feel very unsafe for road use. There are actually two ongoing bulletins already in regards to this but in the manufactures Support program that notifies the issue has excluded 2014. L-SB-0009-21 & CUSTOMER SUPPORT PROGRAM 21LE01. My vehicle has now developed this internal leak and has been inspected only to provided the matching four Diagnostic Trouble Codes (DTCs) C1391, C1252, C1256, & C1253 that are mentioned in the program.

Brake system completely went out while driving with no warning. Traction control lights came on, abs lights came on and other warnings. Vehicle had to be towed as the vehicle had no brakes what so ever. Vehicle was taken to the dealer. It is a known problem with the hybrid cars from toyota and lexus. They have a repair program for the same car but my car missed it by a few months. Hundreds of thousands of the same model are being repaired but they refused to repair mine.

On Apr, 19th 2016 Lexus and Toyota sent enhanced warranty on the brake actuators on these vehicles: 2006 ' 2007 gs 430, 2007 ' 2011 gs 450H, 2008 ' 2011 gs 460, 2007 ' 2012 ls 460, and 2006 ' 2008 rx 400H seem like the real problem haven't been solved and cars that were build after those years still reporting of same problem prematurely failing on brake actuators across the forums. Hope NHTSA look into this matter and have citizens drive road in safer environment. Sincerely,
