What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2011 Lexus Ct, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
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.
The contact owns a 2011 Lexus CT200H. The contact stated that while operating the vehicle, the ABS and brake warning light and check engine warning light remained illuminated. The vehicle was taken to the local dealer who diagnosed that the brake booster and brake booster pump were faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was unknown.
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.

The horn quit working, but the alarm that came from the horn still works. I suspect it's the clock spring.

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.

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.

. ON THURSDAY, 11/7/13, I GOT INTO MY CAR TO GO TO WORK AND THE DASHBOARD GAUGE INDICATED THAT AIR PRESSURE IN ONE OF MY TIRES WAS LOW. I LOOKED BUT THEY APPEARED TO BE OK. I HEADED TO MY MECHANIC INTENDING TO STOP THERE ON THE WAY TO WORK. THE CAR PERFORMED NORMALLY ON THE STREETS AND THE HIGHWAY. MY FOOT WAS ON THE BRAKE AS I ENTERED THE EXPRESSWAY DECELERATION LANE TO EXIT, CAR STILL FINE. I PROCEEDED DOWN THE EXIT RAMP, MY FOOT NEVER LEAVING THE BRAKE PEDAL, I APPLIED A BIT MORE PRESSURE TO THE BRAKE WHICH INITIATED A "FLAT TIRE" , BUMPY SORT OF RIDE. I SLOWLY KEPT BRAKING ON THE EXIT RAMP WHEN THE CAR SUDDENLY ACCELERATED, MADE A 90 DEGREE TURN TO THE RIGHT, STRAIGHT INTO A RETAINING WALL, THE CAR WENT UP THE WALL (OFFICER SAID THERE WAS A MARK ON THE WALL ABOUT 10-11 FEET UP), FLIPPED OVER AND LANDED ON IT'S WHEELS. I HAD ABSOLUTELY NO CONTROL OF THE CAR, COULDN'T STEER OR STOP IT. NO KEY TO PULL OUT... PUSH BUTTON STARTER. AIRBAGS DID NOT DEPLOY. I SUFFERED A FRACTURED STERNUM , FRACTURED SACRUM (DUE TO MY WEIGHT ON THE SEAT BELT AS THE CAR HIT AND TUMBLED) PLUS OTHER INJURIES. CAR WAS TOTALED. YOU WOULD THINK FROM HITTING A WALL TO FLIPPING TOTALLY AROUND, SOMETHING WOULD TRIGGER AN AIRBAG TO CUSHION ME AGAINST BONE FRACTURES. AND THIS WAS NOT A CASE OF REACTIVE BRAKING (HITTING THE ACCELERATOR BY MISTAKE)...MY FOOT NEVER LEFT THE GAS PEDAL FROM THE DECELERATION LANE ON HIGHWAY TO VERY SLOWLY DESCENDING THE EXIT RAMP. LOST MY JOB, NO SICK PAY. WAS SCHEDULED TO TAKE MY CERTIFICATION TEST AS AN AEROBICS INSTRUCTOR IN 3 DAYS TO ENABLE ME TO GET A SECOND JOB. STILL ON PAIN MEDS, GOING THROUGH TESTS, UNABLE TO WORK OR EXERCISE, ETC. *TR

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.
