2012 Lexus CT - SERVICE BRAKES Failure Complaint (#b1779b)

2012 Lexus CT

• Failed components: SERVICE BRAKES

A prevalent issue observed in the lexus ct200h and toyota prius v models is the internal leakage of brake accumulators, as they utilize identical part numbers. Consequently, the actuator emits a buzzing sound intermittently as it attempts to maintain the necessary gas pressure within the braking system, ultimately failing due to the leak. Numerous articles addressing this concern are available online, highlighting its significance as a safety issue. Many owners have successfully had toyota replace the faulty part at no cost, thanks to the extended warranty covering a period of ten years or 150,000 miles, whichever occurs first. This may be attributed to the higher prevalence of prius vehicles on the road compared to the less common lexus ct200h. A simple search for "c1391 danger" will yield substantial information on the topic. It is disheartening, in my view and that of many others, that a problem posing a risk to public safety due to brake failure has not been adequately addressed. The sudden onset of this issue significantly reduces stopping distances. When it occurs, warning lights for abs, traction control, and brakes illuminate simultaneously. Notably, there are no visible brake fluid leaks associated with this actuator. While toyota provides coverage under the extended warranty, it appears that lexus may not offer similar support, raising concerns about the safety implications discussed across various platforms.
