Traffic on I 5 N came to a sudden stop. I stepped hard on the brakes. The ABS function did not work and my car skidded and would have gone into the lane on my right if I had not corrected the skid. This could have resulted in a serious accident with potential bodily injuries. I had the vehicle inspected by Lexus dealer and they said nothing was wrong with the ABS brake system and that this could be one in a thousand incident. I have driven several other manufacturers autos with ABS and know that the Lexus experience is not how normal ABS brakes should function. This is a serious driving hazard and I have not received a satisfactory solution to this issue from Lexus to date. Updated 04/08/14

Had to replace the brake fluid in the vehicle at 30000 miles. Lexus requires this supposedly to maintain the integrity of the braking system and provide a safe vehicle. I feel this is a safety defect in the design. Any vehicle' shouldbe robust enough to last much longer than this without this level of service being required by the manufacturer. If the vehicle does really need this, than Lexus should cover it under warranty. Brakes also required disassembly and cleaning at 15000 miles at customers expense.

I went out to grab a bite to eat for my daughter and I came to a stop light at a major intersection. I received the turn arrow so I accelerated thru the turn and then punched the gas to make it thru the next light that will turn red if you don't give it a little gas to get thru it. I make it thru the light and get in the right lane to slow down to make my turn and my brakes don't work and my car starts accelerating on its own. I have no control of the speed so I throw the car in neutral and keep slamming the brakes while the brake malfunction light appears. I'm not sure how my car slows down and I make a right turn into a parking lot and my engine is still sounding like it is accelerating and I am in neutral. My car rolled to a stop, I shut it down and called the Lexus line. The had a towing company out within an hour and the tow truck driver told me this is at least the 10th time he has hauled this type of car for the same thing.

I was driving approximately 30 - 40 mph on the freeway. I went to make a lane change, looked over my shoulder to make sure lane was clear, as I turned back, the car in front of me stopped. I put on my brakes, there was no response from my brakes, they disengaged. My car surged forward and hit the car in front of me. My seatbelt did not have any tension, therefore, my body hit the steering wheel. Nothing has been done. The accident just happened.

Service brakes, March 13, 2011 - mansfield MA I purchased my 2010 Lexus Rx 450H in December 2010. Ever since I bought it, I have noticed that from time to time, when I press the brake pedal, the car seems to surge forward(!) momentarily before it slows down. This happens most frequently. It will happen even if I am only coasting and not touching the gas pedal when pressing the brake initially. It happens to me at least once or twice a week. It is somewhat disturbing. I have mentioned this to my Lexus dealer, but they have dismissed my concerns both times I brought it up. Has anyone else noticed this issue? view details

I was driving my new Lexus 450H (2,000 miles) in a fresh light snow (1.5 to 2 inches) in incline village nv at 25 miles per hour on a slight decline when I depressed the brake pedal to slow down for a curve a few hundred feet away. It locked the wheels immediately and as a result I had no steering control. Given that I had enough time to get my foot off the brake before having to make turn ahead, I removed my foot from the brake (I have been driving in snow my whole life since I was raised in Canada) and it had no effect -- the wheels remained locked as I gained no control of steering and the vehicle continued to slide until it hit the guard rail across the street as I entered the turn at some 10 to 15 miles an hour. I am convinced that the problem lies in the 450H trying to generate power whenever the gas pedal is not depressed -- this is different than my former Lexus 400H which only tried to generate power when the brake pedal is depressed (I know about the new logic because the power gauge (that shows whether the batteries are charging or discharging) shows charging whenever one's foot is taken off the gas pedal on the 450H, not on the 400H). Needless to say, I immediately went to the local Lexus dealer and traded the vehicle for an RX350 that will drive like a normal car. I am only interested in having people that live in hilly snow conditions avoid buying the rx450H as they will necessarily have the same experience. I do not have VIN at this time as I am at my second home in California at this time.

I have a new 2010 Lexus rx 350 keep stalling while I was waiting for traffic light, problem stated soon after I started driving, while mileage was around 1500, when the car stalled ABS (anti brake system) sign showed up. I took the cars several times back to Lexus, they used their computer to check computer records of my cars and claimed nothing wrong with the car, until the third time I went back, the brake malfunction warning sign showed up while Lexus's technician was inside the car with me, then they kept the car 10 days and repaired the problem, but still claimed nothing else is wrong with the car, cannot explain why the car stalled, they claimed computer of my car didn't record any stalled history therefore no proof car stalling problem. I told them the computer of my car is so defect that they didn't find brake malfunction problem until the sign showed up in dashboard, why are they still rely on the computer" they kept the car for 10 days to repair a brake, how come it takes 10 days" I believe they found out that the car has more than brake problems, and they know all the Lexus car has potential pending problem, either electronically or computer that control the electronic, imagine if my car stalled while I was driving on the high way, for the safety of all the cars on the street, your division should look into the problem of not only Toyota but also Lexus and other cars made by Toyota motor Inc.
