2012 Lexus CT

The brake booster assembly has developed a leak in the pressure accumulator resulting in constant actuation to keep the pressure sufficient. Complete failure is impending with a C1391 code and loss of power brakes. Toyota has offered a CSP to address this issue but only for a very limited time and at the time of creation of said TSP only covered model years up to 10 years old. 2011-2013 CT200h models are not covered by this CSP. Furthermore due to the limited time period in which the CSP was active, many cars were not covered due to not developing fault codes at that time. Part prices alone to resolve this issue from the dealership are above $2000.

At ~101,000 miles, my 2012 Lexus CT200h triggered error code C1307, indicating a failure of the brake pressure accumulator / brake booster system. Prior warnings appeared via dashboard alerts. This caused reduced braking performance, creating a serious safety risk. The issue was confirmed by a Lexus dealer and independently by a certified mechanic, who repaired it. I contacted Lexus Customer Support for coverage under CSP 21LE01, but they denied it due to the 10-year time limit, even though my vehicle was within the 150,000-mile limit. Dealer estimated ~$4,600; I had it repaired independently for $2,000, sourcing parts online at ~50% of dealer pricing. This is a safety-critical defect acknowledged by Lexus under CSP 21LE01. I respectfully request that NHTSA review this defect to ensure Lexus extends proper coverage and prevents future safety risks for other owners.

Brake failure while driving. The brake pedal went soft when pressed and all the associated warning lights illuminated. ABS, traction, control, etc. This is a known issue for Toyota and Lexus, and even after servicing my vehicle at the dealer for the last two years I was never notified that this was a concern.

My 2011-2013 Lexus CT200h exhibits malfunction indicator lamp illumination for the brake, ABS, and traction control systems, accompanied by diagnostic trouble code C1391. Research indicates this is a known manufacturing defect, and I possess documentation from the customer support program confirming coverage for this issue in vehicles of this model year. However, the Lexus dealership and service advisors refuse to acknowledge this coverage and saying that it is expired. Therefore, I require guidance on how to proceed with resolving this matter.

A prevalent issue observed in the Lexus CT200h and Toyota Prius V models is the internal leakage of brake accumulators, as they utilize identical part numbers. Consequently, the actuator emits a buzzing sound intermittently as it attempts to maintain the necessary gas pressure within the braking system, ultimately failing due to the leak. Numerous articles addressing this concern are available online, highlighting its significance as a safety issue. Many owners have successfully had Toyota replace the faulty part at no cost, thanks to the extended warranty covering a period of ten years or 150,000 miles, whichever occurs first. This may be attributed to the higher prevalence of Prius vehicles on the road compared to the less common Lexus CT200h. A simple search for "C1391 danger" will yield substantial information on the topic. It is disheartening, in my view and that of many others, that a problem posing a risk to public safety due to brake failure has not been adequately addressed. The sudden onset of this issue significantly reduces stopping distances. When it occurs, warning lights for ABS, traction control, and brakes illuminate simultaneously. Notably, there are no visible brake fluid leaks associated with this actuator. While Toyota provides coverage under the extended warranty, it appears that Lexus may not offer similar support, raising concerns about the safety implications discussed across various platforms.

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 is not much stopping distances when and 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. The brake booster pump may fail causing a deactivation of the Vehicle Stability Control system and a loss of braking assist. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 126, Electronic Stability Control Systems."" Deactivation of the vehicle stability control system or a loss of braking assist increases the risk of a crash.

I, along with many other Lexus CT200H owners have had issues regarding the brakes on the vehicle. I have code: C1391 as reported on a diagnostic tool from Autozone. This has been an issue on my vehicle for months and I’ve read reports of this repair costing upwards to $3000!! Many of us do not have that kind of money to fix a vital function of the vehicle that rely on to keep us safe. If it’s a common and reoccurring issue, I believe it should continue being taken care of by the manufacturer. There was a recall in the past, but it isn’t fair for those who have had this issue after the recall and are responsible to pay this ridiculous amount afterwards!

A 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 many 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. There are no external brake fluid leaks involved. for this actuator. Toyota covers it under extended warranty, although it appears as though Lexus does not(?), this is a major safety hazard and concern for a heavy amount on several different websites. The trouble code is: C1391. I called Lexus of Austin and was told there are no recalls, after looking up my VIN#. Searching for “c1391 danger” will yield many incidents of this. This is quite a serious issue that needs government interference. Thank you for taking the time to read this.

I am writing to bring to your attention a serious safety issue that occurred with my vehicle. While driving on the expressway, the engine oil burned and the oil warning light illuminated on the dashboard, posing a significant risk to my safety and the safety of others on the road. Specifically, the engine oil system malfunctioned, causing a sudden and complete loss of engine lubrication. This incident can be verified through an inspection of the vehicle, which is available upon request. My safety and the safety of other motorists were severely compromised due to this malfunction. The sudden failure of the engine oil system could have resulted in a catastrophic engine failure, potentially leading to a loss of control of the vehicle at high speeds. Fortunately, I was able to safely pull over to the side of the road, but the situation could have been much worse. Upon experiencing the issue, I had the vehicle towed to Service Center where the problem was reproduced and confirmed by a certified mechanic. They conducted a thorough inspection and confirmed that the engine oil had indeed burned, leading to the illumination of the oil warning light. The inspection report from the service center is available for review. Additionally, I reported the incident to the vehicle manufacturer and my insurance company. Both entities have documented the issue, and I am awaiting further instructions on how to proceed. There has been no involvement from law enforcement as there was no accident or

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

Engine has oil use and knocking sound that neither Lexus know what is wrong. A lot of Lexus owners are experiencing the same issues with no resolve. Lexus/Toyota needs to fix the issue with these years models.

I’ve now had 2 tire sidewalls blow out in 1 month. They are both 215/45/17 sized tires

Excessive oil consumption. I purchased the car January 7, 2021 and checked the oil on March 15, 2021 before a long trip and the oil didn't even register on the dipstick. I followed procedure before and up to checking the oil. I checked it when it was delivered and it was at the appropriate level.

First noticed excessive oil usage. Then, engine rumble. Temperature warning light. Took to repair shop who was unable to repair stating ONLY Lexus has tools required to repair. Lexus will not divulge how to repair. Lexus states a letter was mailed to me (never received) in 2016 for a service issue - warranty enhancement. Thus, they are aware of the issue. Now that I’m having issues with the car (2021), the car is too old and has too many miles, thus, Lexus will not repair free of charge under service issue. I am Scared to drive because of hundreds of on line reports that state car can and make completely stop while driving. Toyota is fully aware of the issue and should be help liable to repair under a recall. Note: I’ve had my car repaired for other issues by Certified Lexus since 2016 and the service centers never mentioned the issue/warranty enhancement - a known issue apparently since 2016.

I drive my lexus every day for work and home, round trip, 150 miles per day, at 130,000 miles my car started burning 1 quart of oil per month, at 150 miles, now using 2 quarts per month, i now have 195 miles, and using 1 quart of oil per week, this is not normal. after reading forums, many other lexus ct200 owners are having the same issues. this has been reported to lexus dealers and the warranty is only good till 60,000 miles. there's been times when my car has no oil and i need to add 3 quarts, this can cause severe damage to my engine.

I had the recommended 100,000 mile service done on my car at approx 106,000 miles. At aprox 109,500 miles I checked my oil after noticing my passenger headlight was out and I would be putting a new one in. When I went through the procedure for checking the oil it wasn’t even showing any oil on the dipstick. After reattempting the procedure and checking to make sure I was on level ground still no oil on the dipstick. It took 2 1/2 quarts to get it to the recommended level. I’m at 110,600 today and again the oil was very low registering between 1/8-1/4 Inchon the bottom of the dipstick. There are no oil spots in my two regular spots between my home and my job and my car does not smoke and has never shown a check engine light and has no stored DTC’s. I’m scheduling an oil change this coming week and I will alert the Service Manager about the problem. I purchased the car used in January from Carvana.

EXCESSIVE OIL CONSUMPTION. I PURCHASED THE CAR JANUARY 7, 2021 AND CHECKED THE OIL ON MARCH 15, 2021 BEFORE A LONG TRIP AND THE OIL DIDN'T EVEN REGISTER ON THE DIPSTICK. I FOLLOWED PROCEDURE BEFORE AND UP TO CHECKING THE OIL. I CHECKED IT WHEN IT WAS DELIVERED AND IT WAS AT THE APPROPRIATE LEVEL.

TOOK MY CAR TO TOYOTA DEALERSHIP. THEY SAID MY CAR IS BURNING OIL. I HAVE NOTICED MY OIL DOES BURN UP QUICKLY, SMELLS LIKE GAS UPON THE DIPSTICK, I HAVE SEEN NO OIL LEAKS. THE DEALERSHIP SAID THEY HAVE SEEN THIS SAME ISSUE WITH OTHER SIMILAR MODELS LIKE IN THE PRIUS. MY CAR ONLY HAS 82,000 MILES. I BABY THIS CAR AND TAKE FOR ALL THE APPROPRIATE MAINTENANCE. THIS IS VERY UPSETTING.

2012 LEXUS CT200H HAS THE SAME BRAKE BOOSTER, ASSEMBLY ISSUE ALL 3RD GENERATION TOYOTA PRIUS'S HAVE. THE ABS/BRAKE SYSTEM LIGHTS ALL COME IN, AND BRAKE FUNCTIONALITY IS LIMITED. ATTACHED IS A SCAN OF THE ISSUE, I HAVE SINCE CALLED LEXUS AND NOTIFIED THEM OF THE ISSUE.

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.
