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.
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.
The following two events happened during the first week of april 2024 event #1: while driving at 65 mph on a freeway, the car decelerated and failed to travel above 40 mph. Simultaneously, three warming lights appeared on the dash: a yellow triangle, the check engine light and a "check hybrid system" warning. Event # 2: same symptoms and dash displays as event number one while traveling at 40 miles up a hill.
The brake booster pump has gone out in the car, ive heard many others say the same thing and its all around the same milage 150k-175k
My ct200h has now recently started to leak fluid from the brake system has started to malfunction due to this known problem by lexus on their 2013 ct200h brake booster/master cylinder as well as the actuator system problem which they had previously put out a statement for. This is absolutely incomprehensible the scope of a dangerous situation this could have put my family in. Imagine if the brakes would have fully malfunctioned and i slammed into the back of a 18- wheeler, the whole top of this car is coming off including everyones heads in the car. I hope this reaches a competent individual who understands the scope of the malfunctioning in the brake system. This is supposed to slow a 2 ton car going from 65 mph to 0 at any instance, if the system malfunctions at the wrong time lives are put at risk. I have full service records through the dealer and constantly do routine maintenance with the dealer. I am highly disappointed in with this matter.
I noticed that the brakes felt a bit weird when engaged. I felt a touch on the brakes and heard as if the abs pump was pumping. Thinking it was something of a fluke, i didnt pay any further attention to it. After not driving the car for couple of days, when i turned on the car a day ago the warning (! , brake, abs, and traction control lights) are all lit up on my 2015 lexus ct200h. After doing some research, i have found an old recall for lexus ct200 h for (2011-2014) see (l-sb-0009-210) from may 11,2021 letter online. A code scan revealed a c1391 error, indicating an abnormal leak in the accumulator. This abs module is the same as the recalled toyota abs module. Please this could be dangerous to me and my family.
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 action to address this critical safety concern. I request that you: thoroughly investigate the issue with the brake actuator in my vehicle and perform any necessary repairs to ensure its proper functioning. Cover the cost of all repairs associated with this defect, as it appears to be a systemic issue rather than an isolated incident. Provide a clear explanation for why this known defect was not addressed proactively and what steps are being taken to prevent similar issues in the future. I am deeply concerned about the potential safety implications of this malfunction and believe that lexus has a responsibility to prioritize the safety of its customers. I expect a prompt and comprehensive response to this complaint. Additional information: i have attached any relevant documentation regarding this known problem
Urgent safety complaint regarding brake system failure and manufacturer's extended warranty acknowledgment to whom it may concern, i am writing to formally file a complaint concerning a critical safety issue with my vehicle, which has significantly impacted its braking system. This issue not only presents a severe risk to my safety and that of other road users but has also been acknowledged by the manufacturer through the issuance of an extended warranty for this specific malfunction. Approximately one month prior to the complete failure, my vehicle began emitting an unusual hissing noise from the brake pedal area, leading to a near-total loss of braking functionality. The incident was characterized by the activation of the anti-lock braking system (abs), traction control, and brake warning lights, accompanied by a repetitive buzzing noise every 5-10 seconds related to the brake system's charging mechanism. The brake pedal became exceedingly soft, rendering the vehicle's brakes nearly non-existent. Despite the vehicle being only a year and a half old and previously showing no major issues, this braking system failure occurred suddenly and without warning. However, in light of the manufacturer's recent communication regarding the extended warranty for this specific problem, it is clear that this is a known issue that poses a significant safety risk. Given the manufacturer's acknowledgment of the defect through the extended warranty, i urge the national highway traffic safety administration to investigate this matter with heightened urgency. The potential for harm not only to myself but to other individuals on the road necessitates prompt and decisive action to ensure the safety and reliability of affected vehicles. I am prepared to provide further information and cooperate fully with any investigations into this critical safety issue. Thank you for your immediate attention to this matter. Sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6)
There is a noise i am hearing while breaking which is the actuator trying to build pressure, but the pressure is being leaked out of the accumulator in the brake master cylinder, all of the “brake” and “abs” lights come on and you will hear the actuator about every three seconds or so. This is a dangerous mechanism which has been known already on a multitude of these same models. Please fix this, as it could have been a dangerous situation this vehicle could have put my family in.
