2014 LEXUS CT

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. Lexus/Toyota has acknowledged this specific defect in Customer Support Program 24LE01 (DTCs C1391, C1252, C1256), identifying it as an "internal malfunction." However, the manufacturer has limi

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 be perhaps because there are several more prius on the road than this rare Lexus CT200H. Just look up “c1391 danger” and see what comes up. In my opinion, as well as many, it is pathetic that an issue in which endangers the lives of others due this brake failure is not further addressed. There i

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 independent mechanic who misdiagnosed it as a TPMS issue. Six months later, a loud chime began sounding repeatedly, unrelated to seatbelt use. I brought the car to Lexus of North Miami, where they diagnosed a failing ABS pump and accumulator — the exact components covered by the CSP. This is a crit

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 jus

C1391 error code All brake dash lights (abs, parking brake, !) came on and brakes would not stop. I had to put my foot the floor to get the car stopped. No warning at all, lights came on and brakes instantly malfunctioned

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.

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

My daughter was involved in a rollover accident 10/24/2023 resulting in a front passenger injury. The passenger's right hand was crushed during the accident requiring a lengthy hospitalization and numerous hand surgeries. The passenger will require additional surgeries in the upcoming future. Front and side airbags was not deployed during the accident. No warnings on the dash re. airbag issues prior to the accident. The car was released to USAA (ie. adjuster) and car was deemed unfixable.

Engine rattles due to head gasket failure and subsequently stops working and defaults to “service hybrid system” this can occur while driving and cause a collision.

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.

At 125,000 miles my engine started knocking. I had been keeping up with all routine maintenance. It was determined that I had a blown head-gasket. After checking online, this is an issue that a # of people are experiencing with the CT200h/Prius drivetrain.

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.
