What owners say

Filed Aug 17, 2017 · Airbags, Body · 110,000 miles · CO · crash

While slowly pulling into parking space in the parking lot of the local post office, with foot on brake pedal car quickly accelerated forward with engine reaving. Car shot forward going over concrete car stops toward a creek and smashed into a stand of trees. Driver airbags deployed. Complete front of vehicle including hood and windshield were smashed and driven into engine compartment. I believe this is a case of unintended acceleration caused by the vehicle malfunctioning. There have been multiple documented complaints of this happening in lexus rx 350 vehicles. The floor mat was securely in place and had not moved and the driver insists her foot was on the brake petal at all times. There were no obstructions in or around the accelerator petal or the brake. Paramedics were called to scene and a police report was filed.

Driver was pulling into a parking spot, just rolling to a stop with her foot on the brake. The car suddenly accelerated into a brick wall and a tree. The front bumper of the car was smashed and the frame was bent. Air bag did not deploy as it should have. Owner contacted lexus legal department the next day and filed a claim. 16 days later a third party investigator recovered the data from the event data recorder. It has been 50 days since the claim was filed and we got a letter today from toyota stating "no defects were identified!" this is totally unacceptable. Toyota settled a 1.1 billion dollar class action law suit regarding "unintended acceleration" cases. Obviously there is a big problem. We will be following up with legal representation. In the mean time the car sits in the garage, while we make payments on a car that is totally unsafe to drive!

On oct 5, 2011 at 7:45 am , I was traveling on a one lane road each way in rural connecticut ( 35 MPH zone). I decided to pass a car that was traveling well below the speed limit when my lexus rx350 lurched forward suddenly and then had a huge burst of accelerating speed. I applied my foot to the brakes and the car slowed very slightly, but started to buck a little and then once again felt like it kicked into a higher gear. My dashboard was flashing " brake failure" as I looked down and saw that my foot was firmly planted down on the brakes. Fortunately, there were few cars on the road and only once did I have to pass a car on a blind curve hoping no one was approaching from the other way, so as to avoid ramming a car in front of me. I had resolved in my mind that I was going to crash, and was trying to find a place to take the car off the road while trying to minimize injury to me. I stopped looking at my speed, but it was clearly in excess of 60 MPH in a 35 MPH zone. I was lucky that day, since there were few cars on the road and the stretch of road I was on was fairly straight. I drove this way for about 1.5 miles when it then occurred to me to shift the car into neutral. Once I did this the car eventually reduced speed to about 5-10 MPH. I threw the car into park and jumped out of the vehicle, which at this point was engulfed in smoke from the failed brakes. Lexus blamed the incident on a stuck accelerator pad, although they admitted when the car came to their shop the pad was not stuck. I know factually that the pad was not stuck, since I looked down at my feet during the episode and saw my foot on the brake, and the accelerator pad in its normal position. This was clearly an incident of sudden acceleration. Lexus allowed me to break my lease and lease a 2012, which now has a brake override system (as of 2011 models) .

On 7/1/2011 at 10.45pm. I was driving my lexus 2010 rx350 eastbound on the lie service road in glen cove ny. I was travelling at 35 to 45 MPH,when suddenly my "brake malfunction light" started flashing on my dashboard. I instinctively tapped the brake, and the brakes did not respond. Then the car had unintended acceleration,I then pressed on the brakes with all my might, to stop this vehicle careering off the road.with gods grace I was able to stop the car by downshifting gears. This is the first time I have experienced this life threatening problem. So far lexus have discredited this experience, by claiming the mat was stuck under the accelerator and or brake. I strongly and vehemently disagree with their evaluation and analysis. I intend to take this matter further with lexus.

In a 2010 lexus rx 350 my grandmother was a passenger in which the vehicle was at a stop waiting for an apartment complex security gate to open. The car suddenly accelerated to speeds above 60 MPH. The vehicle crashed through two apartment complex security gates, went airborne over a busy street and came to rest against the side of a building. To our horror, my grandmother perished in the accident. We are awaiting the information from the black box. I hesitate so say too much because we are still in the decision making process of how/if to proceed regarding litigation. Do not purchase, drive or ride in one of these vehicles.

Filed Apr 9, 2011 · Acceleration · 22,800 miles · DC · crash

Unintended acceleration without ability to brake with my lexus rx 350, at 2 pm on saturday march 12th 2011 with 5 passengers. I was driving at around 30 MPH. The choice was to crash in the car ahead stopped at a red light or go on the side walk, up a steep mount and crash in a brick wall. This is what I did. Nobody was hurt. Police was called and the car was towed. Car was inspected by toyota, no cause was found, car was repaired at a geico approved repaired shop, and I am now asking the lexus dealer pohanka to allow me to return the car and break my lease. In good conscience although no one was hurt, I am not willing to risk a more serious accident after my experience. We would have gotten hurt at a higher speed. This was my first ever crash driving 20,000 miles per year, driving for more than 35 years. There is no doubt something outside of my control happened.
