As stated above, I own and maintain a 2014 Lexus Ct200H. My issue is specifically with the factory ABS and brake booster pump that recently failed due to an internal leak of the pump causing the brakes to feel very unsafe for road use. There are actually two ongoing bulletins already in regards to this but in the manufactures Support program that notifies the issue has excluded 2014. L-SB-0009-21 & CUSTOMER SUPPORT PROGRAM 21LE01. My vehicle has now developed this internal leak and has been inspected only to provided the matching four Diagnostic Trouble Codes (DTCs) C1391, C1252, C1256, & C1253 that are mentioned in the program.

Brake system completely went out while driving with no warning. Traction control lights came on, abs lights came on and other warnings. Vehicle had to be towed as the vehicle had no brakes what so ever. Vehicle was taken to the dealer. It is a known problem with the hybrid cars from toyota and lexus. They have a repair program for the same car but my car missed it by a few months. Hundreds of thousands of the same model are being repaired but they refused to repair mine.
At 125,000 miles my engine started knocking. I had been keeping up with all routine maintenance. It was determined that I had a blown head-gasket. After checking online, this is an issue that a # of people are experiencing with the CT200h/Prius drivetrain.
THE HEAD GASKET IS LEAKING. AFTER SPEAKING WITH SEVERAL MECHANICS WHO WORK ON THIS TYPE OF CAR AND ISSUE AND THEY HAVE ALL SAID THAT "3RD GENERATION PRIUS ENGINES ALL HAVE THIS LEAKING HEAD GASKET PROBLEM, NO OTHER GENERATION HYBRID ENGINE FROM TOYOTA OR LEXUS DOES". WHY WASN'T THIS RECALLED? I DON'T UNDERSTAND HOW TOYOTA AND LE…

THE HEAD GASKET IS LEAKING. AFTER SPEAKING WITH SEVERAL MECHANICS WHO WORK ON THIS TYPE OF CAR AND ISSUE AND THEY HAVE ALL SAID THAT "3RD GENERATION PRIUS ENGINES ALL HAVE THIS LEAKING HEAD GASKET PROBLEM, NO OTHER GENERATION HYBRID ENGINE FROM TOYOTA OR LEXUS DOES". WHY WASN'T THIS RECALLED? I DON'T UNDERSTAND HOW TOYOTA AND LEXUS GET AWAY WITH A SHODDY PRODUCT THAT CREATES A $5-8K EXPENSE ON THEIR VEHICLES THAT IS A DESIGN FLAW AND ISSUE WITH THIS GENERATION HYBRID ENGINE. MY CAR IS ONLY WORTH ABOUT $10K, SO PAYING TO FIX THIS SEEMS LIKE A BAD CHOICE. HOWEVER, I HAVE ALSO BEEN TOLD THAT OFTEN WHEN PEOPLE DO PAY TO FIX IT THEY HAVE TO COME BACK AS THE ENGINE BLOCK ENDS UP NEEDING FULL REPLACEMENT, WHICH IS AN ADDITIONAL $3K.

WE NOTICED A FUEL SPILL UNDER CAR AS WE PULLED OUT OF DRIVEWAY. BROUGHT CAR INTO LEXUS DEALER. WE WERE TOLD THE FUEL TANK WAS CRACKED AND MUST BE REPLACED. THEY TOLD US THE DAMAGE WAS DUE TO ROAD HAZARD AND NOT COVERED UNDER WARRANTY. WE HAD NOT NOTICED ANYTHING UNUSUAL IN THE DAYS PRIOR TO THIS INCIDENT. THE FUEL TANK IS EXPOSED ON THE UNDERSIDE OF THE VEHICLE, AND IS MADE OF PLASTIC. THERE IS NO SHIELD OF ANY KIND TO PREVENT A STONE OR ANY OTHER DEBRIS FROM CAUSING THIS TYPE OF OCCURRENCE AGAIN. WE ARE VERY CONCERNED THAT THIS MAY HAPPEN AGAIN TO US OR ANYONE OWNING THIS MODEL. WE CONSIDER OURSELVES VERY LUCKY TO HAVE DISCOVERED THE FUEL SPILL BEFORE THE TANK EXPLODED OR CAUGHT FIRE. THERE MAY BE A DESIGN FLAW THAT ALLOWED THIS TO HAPPEN. *TR
