Other/I am not sure
The carseat is designed to clip and unclip from the base. When it has been clipped into the base, instead of being securely attached, pushing on the carseat causes it to easily pop out of the base WITHOUT using the release handles. This means that under pressure, the carseat de-attaches from the base, and is not safe or secure. I'm unable to attach a video below, so here is a link to a video showing the issue.

SERVICE BRAKES, ELECTRICAL SYSTEM
A 2013 Lexus CT200h with approximately 122,291 miles developed repeated ticking/pump-cycling noises from the braking system. Shortly afterward, multiple brake/ABS/VSC warning lights illuminated. The vehicle was taken to an authorized Lexus dealer, where technicians diagnosed failure of the brake booster/master cylinder assembly and brake booster pump assembly. Diagnostic trouble codes C1391, C1252, C1256, and C1253 were recorded. The dealer advised that the vehicle should not be driven until repaired because of the brake-system condition. Lexus previously established Customer Support Program 21LE01 for this same brake booster and brake booster pump condition on certain CT200h vehicles, including these diagnostic trouble codes. Lexus confirmed that this vehicle had been covered by that program, but the coverage expired based on time even though the vehicle remains below the program’s 150,000-mile limit. No crash, fire, or injury occurred. I am reporting this because the failure affects the vehicle’s braking system and appears consistent with a previously recognized Lexus brake booster condition.

While driving normally one day, all the brake lights on the dash came on and my stopping power was diminished. I pulled the trouble codes and the only code was C1391 which indicates an "Abnormal Leakage in the Accumulator". This is a major safety concern and a costly repair if left to the customer.

SERVICE 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. 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 limited the coverage to 10 years from the date of first use. My vehicle, with only approximately 62,000 miles, is exhibiting these known failure symptoms just outside this arbitrary time window. A safety-critical component like the braking system should not fail at such low mileage, and the manufacturer should address this design defect via a Safety Recall rather than a time-limited warranty extension that leaves owners of low-mileage vehicles with a dangerous defect.

SERVICE BRAKES
I am submitting a formal complaint regarding Lexus’ refusal to correct a known safety-related defect under Customer Support Program (CSP) 21LE01. My vehicle meets all criteria outlined in the program, yet Lexus denied coverage. Details: 1.Program Coverage: CSP 21LE01 covers Brake Booster and Brake Booster Pump assemblies for internal malfunctions verified by Diagnostic Trouble Codes C1391, C1252, C1256, or C1253. Coverage extends 10 years or 150,000 miles, whichever comes first. 2.Vehicle Qualification: •Mileage: under 150,000 miles •Model year/production range: covered under CSP 21LE01 •Symptoms: brake-system warning lights, reduced braking performance, and internal malfunctions •DTCs: C1391, C1252, C1256, C1253 confirmed 3.Lack of Notification: Lexus indicates that owners were notified of this program starting May 2021. I never received any notice, despite my contact information being current with the DMV. 4.Denial of Repair: Despite the vehicle qualifying under all CSP 21LE01 criteria, Lexus informed me I am “not eligible” for the repair. This refusal directly contradicts the program’s published requirements. Safety Concern: This defect affects the brake system, a critical safety component. Denying the repair for a qualifying vehicle exposes the driver and others on the road to potential brake failure and increased risk of accident. If the brake booster/pump fails while driving, braking can become hard, delayed, or fail completely, greatly increasing the risk of accidents, collisions, injury, or death. Request: I am requesting that the National Highway Traffic Safety Administration investigate Lexus’ denial of a safety-related repair and compel the manufacturer to honor the repair coverage under CSP 21LE01 for my vehicle.

SERVICE BRAKES, ELECTRICAL SYSTEM
There is an issue with the brake booster and brake booster pump assemblies that causes this vehicle to brake poorly. These parts are known to malfunction in Lexus CT 200h models and recognized by Lexus/Toyota. This issue needs to be extended into a recall for the vehicle due to the danger it poses while braking. Lexus/Toyota have acknowledged the issue via their letter: Customer Support Program 21LE01. The original publication of this program was issued on May 20, 2021. Within the letter they recognize that these parts will commonly break down. They issued a brief coverage on vehicles affected. A primary coverage on vehicles prior to November 30, 2022, and a secondary coverage on vehicles within 10 years of operation and 150,000 miles. With the secondary coverage applying to whichever came first. As a secondary owner of this vehicle, I had no idea this letter had been sent out. I had purchased this car late 2022. Had there been a recall notice on these vehicles, I would have been able to speak to a service representative about getting this issue remedied. Seeing as my vehicle is at 143,273 miles and 14 years in use, I am no longer covered through the Customer Support Program 21LE01. During my years of operating this vehicle I have experienced issues when braking. While driving and braking over bumpy roads the vehicle's braking would feel less effective. A week before my vehicle's Brake, Brake System, ABS, and Traction Control lights came on, I nearly experienced a collision with another vehicle while turning at a street light. The brakes should have been more than enough to have stopped the vehicle in the moment, and the ABS should have kicked in when it sensed me attempting to come to a harsh stop. Once I had diagnosed the dashboard lights I received OBD2 code C1391. Indicating an issue with the Power Brake Booster. Seeing as the issue is recognized by Lexus/Toyota, and this issue posing danger while operating the vehicle, there should be a recall imposed.

SERVICE BRAKES
My daughter was driving home at night and the vehicle brakes did not respond normally after coming to a gated entry, she was able to stop with limited braking power and luckily she did not get into an accident. The vehicle gave no warning prior to the incident, and started to show all 4 lights on the dash after the fact;BRAKE, CAUTION, ABS, Stability Control with a beeping sound. She had to stop the vehicle immediately because we felt if was unsafe to do so. The car was stored in the garage for a few days waiting for the codes to get scanned but after starting it the errors were gone, I was able to take a long drive without a problem. Then once again while driving (not when starting the vehicle) the codes reappeared and have been scanned and shows multiple errors; C1252, C1253, C1256, and C1391. This corresponds to the errors in the Brake Booster Pump. Now the car is beeping all the time and probably needs expensive repairs. The vehicle is available for inspection upon request.

The contact owns a 2013 Lexus CT 200H. The contact stated that while driving at an undisclosed speed with the cruise control activated, the brake pedal was depressed and the ABS, traction control, and master warning lights illuminated. The message "Check ABS System" was displayed. The cruise control feature then became inoperable. The vehicle was taken to an independent mechanic, who retrieved DTC: C1391, indicating an abnormal leak in the brake actuator accumulator; however, the contact was unaware of which parts needed to be replaced. The contact stated that the transmission later failed to shift into drive(D) or reverse(R). The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 200,000.

SERVICE BRAKES
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.

FUEL/PROPULSION SYSTEM
I was driving my 2011 Lexus CT 200h and while driving my vehicle abruptly came to a stop in the middle of the road posing a safety risk to me and my passengers without warning. Up until this time, I had not received any "Check Engine" lights or any indication of failing units. At the time my car suddenly stopped, my gauge read 1/4 tank full. I was forced to call for roadside assistance and had to wait hours for a tow truck. Once transported for repair, the technician claimed it was a failed fuel tank sending unit that caused my car to stalled suddenly in the street. However, after researching other similar issues/instances I believe the sudden engine stall on a Lexus hybrid is almost certainly caused by an issue with the fuel pump or another critical fuel system component, not the sending unit resulting in this severe safety concern.

SERVICE BRAKES
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.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, UNKNOWN OR OTHER
Driving down the 99Freeway at speeds approx. Up to 72mph, my abs,traction, and brake lights illuminated at the same time on my dash. I pushed on my brake pedal in order to slow down and pull over, my brake pedal was extremely hard to push in and no matter how hard I pushed it didn't appear to be slowing the vehicle down. I pushed on the emergency brake slowly to help slow down safely and was able to get pulled over. I turned the car off and proceeded to call a friend for help. My friend suggested that I start the vehicle back up and see if I was comfortable enough to continuing to drive it to get myself off of the freeway, which I did. Then when I got off the freeway, I noticed all the lights had gone off and the car felt like it was driving normal again. I proceeded home. The following day my check engine light came on saying to check hybrid system. After being informed to clear the check engine to reset everything my car seemed fine. Then approximately 3 weeks later the abs, traction and brake light came back on and I had difficulty braking. This time and alarm started beeping inside my car as well, the check engine light saying traction battery is not charging and my vehicle does not want to stop. I've been researching different forums online and I'm seeing a numerous amount of other Toyota and Lexus owners with very similar complaints with their cars as well. I've replaced my brake pads, replaced my 12v battery and key fob battery as well. So far I still have no brakes and this is my only vehicle so I'm really hoping this turns out to be a recall or something cause I can't afford to do the repairs .

SERVICE BRAKES
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 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, as it did me as I was driving today. There were no engine lights as I started my drive. 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. The trouble code is.: C1391. Also, I went to Sewell Lexus of Dallas today and was told there are no recalls, after looking my vin #. The service program had expired and there is nothing they can do for me. Please extend the program or issue a recall for this dangerous failure. The repair cost is substantial and should be covered for a known flaw.

SERVICE BRAKES, ELECTRICAL SYSTEM
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.

UNKNOWN OR OTHER
For several years now, I have been experiencing incidents where someone and/or a group is hacking into my radio and/or satellite radio systems and trying to lure me into conversation, make comments, or actually sing to whatever it is I'm listening to. Most incidents have been reported to the NHTSA, which they have been filing. Please know that sometimes the "noise is constant", as well as it appears that someone is actually connecting to my vehicle because I can feel it (also reported). I also hear people speaking from the outside of my vehicle (usually the front end on both sides). It has become a distraction at times, which poses risk to not only myself but other drivers as you can imagine. What can be done to mitigate someone attaching to my vehicle? I am also under the impression that they are recording me or using me as podcast material, which is against the law in various states to varying degrees and without my authority. Please advise, as it has been ongoing for years. Thank you for your assistance. DATES OF INCIDENTS: Ongoing since late 2018, if not earlier.
