2010 Lexus 250hs brake actuator. Driving along a city street going 55 MPH. Slowing down to approach a stop light. Immediately after depressing brake pedal the red brake light and ABS light comes on. My pedal goes straight to the floor and I have no brakes and almost crashed my car into the rear end of another car. I had to hit the ca shifter into b mode and fly into the grass to stop. There was a canal right there I almost went into. This was a recall in 2010 and VIN specific. I have read a million forums that this is a chronic issue with this car. My cer has 81,000 miles only. Lexus corporate said they will not cover the 2,400 part/labor. I think this is extremely dangerous safety issue that this part can go out while driving. I drive over a high bridge to get to work. What wound they have done when getting a law suit when I'm belly up in the ocean if by brakes went out on the bridge. …
I had parked the car in a grocery store parking spot between two cars and had my foot on the brake. I was about to shut off the ignition when the car suddenly moved forward. Intuitively, I pressed harder on the brake, but the car speeded up, jumped over two parking barriers, travelled about 50 feet at high speed, hit the back of another car, a Honda odyssey van with sufficient force that the Honda itself jumped over a parking barrier and a curve and hit a pillar in a building's veranda. My car then stopped and then I turned off the ignition. My car thus experinced unintended acceleration and, in spite of jumping over parking barriers and hitting another car with substantial force, the air bags were not deployed. …
As my wife was driving car, she received (4) - lights on dashboard about break and ABS system. She was driving on 610s in houston, texas. Then all of sudden she was feeling break was not working as should and receiving noise like turbine running. It was vacuum from break. We took car to clear lake Lexus dealership for repair. They run computer and found code c1391/89 accumulator leak malfunction. Accumulator pressure sensor input does not increase before breaking or while the pump motor is operating. Accumulator pressure sensor input reduction rate exceeds the specification before braking and while the pump motor is not operating. The dealership quoted for repair $3400 approx. I believe this should be a recall and/or warranty since defective part. The car has only 82K mileage and in very good condition.
