NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

NHTSA complaint 11720696. Filed by an owner and not verified by NHTSA or by us.

The vehicle's Brake Booster Pump Assembly and Brake Accumulator are exhibiting signs of imminent failure. While the vehicle is in "READY" mode and stationary (in Park), the brake booster pump cycles on and off at an abnormally high frequency (every 15-30 seconds). Additionally, an audible hissing or "squawking" noise can be heard from the brake actuator assembly after the pump cycles, indicating an internal pressure leak within the accumulator. This condition creates a significant safety hazard. If the brake booster pump fails due to this excessive cycling caused by the internal leak, the vehicle will experience a sudden loss of power braking assist. This would result in an unexpectedly …

common problem with these Lexus ct200h, as well as Toyota Prius V models, are that the brake accumulators begin to leak internally, as they share the same part numbers. Therefore, the actuator will buzz every few seconds trying to keep pressure in the braking system to a safe operating level of gas pressure to no avail due to this leak in the actuator. After it quits buzzing from shutting the car off, you can hear the air leak hissing the pressure away. There are tons and tons of articles on this issue online as this is a major safety concern. Many have had Toyota replace the part free of charge as well due to the extended 10 year, or 150k miles, in whichever comes first. warranty. This may …

I’m reporting a serious safety issue with my 2014 Lexus CT200h involving the brake booster and ABS pump/accumulator system. This issue is well-documented across Lexus CT200h and Toyota Prius V models, which use the same components. Lexus quietly issued a Customer Support Program (CSP) for the affected part but never notified me. I contacted Lexus and was told they “didn’t have to” notify all owners. After escalating, they claimed a letter was sent, but I confirmed my address and never received anything. Several months before the CSP expired, I noticed inconsistent brake response, a soft/spongy pedal, and warning lights: ABS, traction control, brake, and TPMS. I took the car to an …

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 …
