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.

ABS light or ABS activating by model year
What owners say
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.
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 .
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.
Abs brake actuator is failing and making a loud noise when brakes are applied. This seems to be a common issue for lexus. Contacted lexus dealer and they told me the car is not covered under any recalls or warranty extensions.
