Open the full vehicle complaint log (all categories)Brakes suddenly failed in the middle of driving causing a major safety hazard. There was no warning. Went to the dealership and was diagnosed “Brake - Fluid Accumulator: INSPECT AND FOUND CODE C1391, ABNORMAL LEAKS IN ACCUMULATOR, RECOMMEND TO REPLACE BRAKE BOOSTER, MASTER CYLINDER AND PUMP. The brake fluid accumulator is a part of the Anti-Lock Brake System. The accumulator stores brake fluid under pressure from the ABS Pump and can instantly provide fluid under pressure to the brakes.” It appears this issue is not an isolated incident and others with the same or similar year/model have had this issue. It is extremely dangerous that the brakes suddenly failed to function without warning. The brake pads and brake fluids were adequate and the vehicle was up-to-date on regular inspection and maintenance.
C1391 error code reported which is linked to Antilock brake system with leak in accumulator requiring replacement of brake booster pump, cylinder kit and other ABS parts cost running to $3550. My VIN number search on nhtsa.gov shows no such recalls for my vehicle as "0 unrepaired recalls". I never got recall notification regarding this issue but Lexus says I should have been notified.
THE BRAKE IS VERY SPONGY. THE PEDAL GETS VERY LOW TO THE FLOOR.ITS HARD TO STOP THESE CAR. BRAKE FLUID, BRAKE PADS AND ROTORS CHECK OUT FINE AT THE DEALERSHIP. THERE ARE COMPLAINTS ABOUT DEFECTS WITH THE MASTER CYLINDER. MY CAR HAS 44000 MILES AND THE PROBLEM IS CHRONIC. YOU NEED A LARGE STOPPING RANGE WHEN USING THIS CAR. LEXUS CLAIMS I NEED TO GET USE TO IT
