2014 Lexus CT200HElectrical systemBrakes

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 critical safety failure. Loss of braking pressure compromises stopping distance and puts my safety and others at risk. Lexus refused assistance because the CSP expired, even though the problem began earlier and I sought help. Corporate and their Resolution Team were dismissive and unprofessional. The issue is reproducible and confirmed by a certified Lexus dealer. Thousands of drivers online report the same pattern: trouble code C1391, buzzing brake actuator, unexplained chimes, hissing noises after shutdown, and external fluid leaks. Some dealers reportedly told customers to disable the chime rather than investigate. Toyota Prius owners with the same part received repairs under warranty or recall - Lexus drivers did not. I urge NHTSA to investigate this defect before it leads to serious injury or death. This is not normal wear. It's a known mechanical failure affecting a critical safety system. What makes this even more dangerous is that most owners won't do the deep digging I did to connect it.

Abs, traction control , brake, a yellow exclammation point, red brake light all come on, as warning lights on the dash board, and the breaks start to feel spongey and not work as well. The actuator starts to buzz every few seconds trying to keep pressure in the braking system, but it cannot due to a leak in the accuator, in which then causes the abs system to deactivate, a known problem of the lexus ct200h, many of the other lexus had this problem as a recall as well- lexus should be fixing this for people its a...

major safety issue that the brakes start to not work out of no where and its not fair to the owner to be responsible for this enormous bill to fix when its a known problem of lexus! It states online all over the place that ct200h vehicles may have brake, abs and or trac warning lights on or a check vsc message displayed due to a small brake fluid leak inside the brake booster assembly with master cylinder, abs actuator failure, and online lists all the codes. It says if the condition is verified the vehicle will be repaired with new brake booster and brake booster pump assemblies but not all lexus establishments are cooperating with this, and its not safe!

received CUSTOMER SUPPORT PROGRAM 24LE01 NOTIFICATION for issues related to Brake Booster and Brake Booster Pump Assemblies. Indicator lights, such as Master Warning Light (Yellow) and SLOP Indicator (Yellow) have appeared while reversing out of a parking spot when no water puddles are present and moving foward (clear day/road) where the vehicle doesn't catch the gear to move initially. Once braking, the system seems to reset itself and allows for a "normal drive". The experience is intermittent, and not...

often- the dashboard warning lights come on infrequently and is not consistent. Lexus Dealer/Service Shop advised a charge of $145 to look for diagnostic codes C1391, C1252, C1256, C1253. If they find these codes, then they will check the extended warranty to determine if they will charge you or not under their customer support program which really doesn't tell the car owner one way or another. The service adviser said only a Lexus authorized dealer can check for the diagnostic codes and can't be obtained from a traditional code reader at retail outlets such as Autozone, or OReilly, etc. The issues with the Brake Booster and Brake Booster Pump Assemblies sounds like a critical issue with deadly affects if not looked into. The method of the dealer seems shady to get this looked at and for a price to be passed on to the car owner.

DRIVING ON HIGHWAY AND ALL OF A SUDDEN AFTER A LOUD NOISE THE bottom of the vehicle went on fire. we called the fire department who put out the fire. After looking at the bottom I notice that the crankcase had a big hole. it seems that a valve went right through the cracnkcase. resulting in hot engine oil going on fire. The car is only 5 months old and Carmax will not pay for the repair which could cost me 5,000 dollars. I paid 27,000 for the car.

caused the vehicle malfunction jthkd5bh3f224391 c1214 toyota meaning the brake booster with master cylinder (skid control ecu) monitors the hydraulic control system. The brake booster with master cylinder (skid control ecu) sets the obdii code when the hydraulic control system is not to factory specifications. An analyst has pulled the cdr of the vehicle stating the vehicle malfunction of the lexus that caused the accident- need investigation why the vehicle did not alert me any maintenance messages, why the dealership did not alert me any precautions on the malfunction of the vehicle. The car accident resulted in the freeway shutting down, could have harmed many people due to the vehicle losing control without any notice thank you for your time

I had my headlights replaced under a recall. Roughly one year later my headlight is out again. It seems the problem has not been resolved. The headlight assemblies are very expensive and contain a lot of parts. I'm not sure where the problem lies, and therefor I'm not sure what needs to be replaced.

Lexus is aware of a safety issue that has caused fires due to an improper wiring harness installed on toyota prius and lexus ct200h vehicles. I asked for this to be covered under the warranty enhancement program (i was not made aware of the existence of it till very recently, but it expired in october 2019). They refused, citing the fact that I did not spend enough money with lexus to service the vehicle. Now, even after lightbulb and fuse replacement, the low beam headlights in the vehicle are inoperable.

The driver door on my car will not open from the inside or outside. This is the 3rd time I have had an issue with the door locks on my car. The driver door lock actuator stopped working at 60000 miles, so I spent the $500 to replace it. Then the passenger front door actuator started acting up, and not working. Now my driver door will not open at all, the car currently has 85000 miles on it. This seems to me to be a safety issue, not having some kind of manual over ride to get the door open. I have been looking on...

the internet a lot, and have found this to be a common issue with toyota/lexus vehicles. I am a disabled veteran and trying to crawl out of my tiny car is very painful. I can only imagine what would happen if I were to get in a wreck and not be able to open my door.

The steering wheel gets stiff, locks eventually and the car goes dead within couple of minutes while driving. Upon 1st diagnosis dealer reported that it was due to bad battery and they replaced the battery. But the same problem has repeated 3 times now within a span of 2 months. Dealer is not able to diagnose the problem whereas the same issue occurs every time. This is life threatening as the steering wheel locks while driving. I have been stranded in the middle of a street and major cross junctions.

Both headlamps went out with 1 week of each other. Replaced with sylvania h11 xenon bulbs as recommended by autozone website as compatible. Installed both lights, verified they worked, drove approximately .5 Miles to stop for lunch. Turned off car and entered restaurant. Approximately 5 minutes later, someone yelled a cars on fire. Front of my car was engulfed in flames. Fire department sawed hood off and distinguished flames. Car was a total loss. Lexus dealer service rep scolded me that I should never ut...

after market bulbs in their cars, to which I pointed out that maybe their manual should state such a fact. I believe there is some surge issue that caused both my headlamps to go out in the first place and that the sylvania bulbs ran hotter than the oem bulbs which triggered the fire. Lexus will not share with me the pictures proving both bulbs were in stalled incorrectly and I have a hard time believing that since u have to insert and turn the bulbs - I would have seen if they weren't in correctly. The car has since been sold off but autozone came out and took the bulbs and wiring to their 'lab'. There's no other plausible reason for the fire other than the bulbs....

1) A light in a dashboard came on saying "check hybrid system", I took it to the lexus dealer , they changed the non hybrid battery), charged me $350 for it and reset the computer. 2) A week after, the light started appearing again with the same message, the message appeared in the morning, in the way back home, coming out of the speedway , all the lights in the dashboard came off (brakes, engine, all of them) and I lost complete control of the car: no brakes, no steering, no nothing. I tried restarting the car...

again, it did, and the next day was driven to the dealer again. They took it in, had it over 2 days, said that they found a "loose cap in the hybrid battery", reset the computer one more time and gave the car back to me. 3) The car did not feel the same, it was like if the switch between hybrid and gas model was off, too accelerated or something, but for the most part no major issues until yesterday (a week and a half after the previous incident). Same thing happened this time, while driving the car, all the lights on the dashboard came on and the car lost everything: brakes, steering....Impossible to control. I was lucky one more time and nobody was hurt . This time the car did not start again. We called a tow truck and sent it to the dealer. Loosing absolute control of the vehicle is not aceptable. I felt I was trapped in a killing machine. This complete system failure happens while driving. I communicated this to lexus.

Each time the fog lamps are used, seems the electrical system pops the fog lamp glass. This has happened 3 times on both driver and passenger side. Including piping of the factory fog lamps that came on the vehicle and then the replacements. The fog lamps cannot be used without popping.
