NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2014 Lexus CT:
Pedestrian alert sounds
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.
What 2014 Lexus CT owners say
Brakes
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 hard brake pedal and significantly increased stopping distances, drastically increasing the risk of a crash. …
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. …
Engine & cooling
Engine started misfiring recently at engine cold start and from hybrid transition to engine startup. Engine light came on with reports codes P0302 and P0304. Additionally, another error code P0607 also was detected. Had a certified mechanic assess the car and replaced the four coils for the CT200h. No change in issue. New issue developed this past Monday with an engine temperature light flashing on. Stopped and put a half liter in the coolant reservoir. Engine temperature light did not come back on. Took the car to a certified mechanic and told him to pressure test the coolant system. The mechanic confirmed the head gasket is blown. In the Lexus CT200h online forum there is a clear and compelling case that the EGR malfunctioned and directly contributed to the head gasket blowing. This car has approximately 128,000 miles. I would encourage you to read the Lexus CT 200h forum.
The head gasket is leaking. After speaking with several mechanics who work on this type of car and issue and they have all said that "3rd generation prius engines all have this leaking head gasket problem, no other generation hybrid engine from Toyota or Lexus does". Why wasn't this recalled? I don't understand how Toyota and Lexus get away with a shoddy product that creates a $5-8K expense on their vehicles that is a design flaw and issue with this generation hybrid engine. My car is only worth about $10K, so paying to fix this seems like a bad choice. However, I have also been told that often when people do pay to fix it they have to come back as the engine block ends up needing full replacement, which is an additional $3K.
