2010 Lexus RX brakes complaints
Page 2 of 2: complaints 11 to 18 of 18, newest first, as owners wrote them.
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 wanted to alert you that other hybrid models that were manufactured with the same braking system as the prius suffer the same issue. I have a 2010 lexus 450h rx and its brakes disengage when I am driving on bumpy roads and over pot holes. I live in a northeastern city with many bumps and my brakes stop working often and as a result I have to slam them on much more quickly. Although I haven't had a crash at this point, I can easily see running into the back of a stopped car in front of me if my brakes disengage at the wrong time. This is a continual issue and I don't have a specific date but given the prius recall, I am confused why my own brakes have not had a similar software fix and the issue sound exactly the same. The date below is non specific. I have had the car from dec 2009 until now and the issue has been continuous. The brakes appear to work fine on smooth roads.
I purchased my 2010 lexus rx 450h in july of 2009. 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 when driving over bumpy roads. And 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. I noticed this even before I had heard of the toyota recall on hybrid prius brakes, but from what I read, the issue sounds similar to the prius hybrid 2010 problems. But there is so far no recall on lexus 2010 hybrid brakes. Has anyone else noticed this issue?

Lexus hybrid SUV 2010 rx450h. Car was in snow setting and when I tried to brake on a light snow surface, there was no response from the brakes and I also was unable to steer. I continued forward until I reached clear pavement and was then able to brake. This happened 3 times today under the same conditions.
