Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

RX 350

  • 89,500 miles


While driving at 55 mph steady on highway the car suddenly shifted into neutral and coasted to a stop. There was no abnormal sound associated. While stationary I tried shifting into reverse or low gear with no response. I shut the car off and restarted it, the car would shift into drive and returned to normal operation for a short period and then shifted into neutral again. After multiple start/stops I was able to get the car home and had it towed to the nearest Lexus dealership the next day for evaluation. In the wrong traffic conditions (congested highway or unsteady terrain) this could have been a serious safety concern, especially if my wife was driving the vehicle when it happened. After 2 days of no response I was told that the fault codes indicated that I needed a new transmission (at a cost of $6900), there was no way it could be repaired. No other details of the damage to the transmission were provided. This is a 2010 Lexus rx 350 with 89,500 miles and has been maintained regularly. For this vehicle, based on the mileage and care put into it, I believe there was a defective part in the transmission but cannot verify it. I was not offered any compensation (because it was officially out of warranty) and had the vehicle serviced (transmission replaced) by an independent maintenance shop. The second shop confirmed a mechanical failure within the transmission, requiring replacement.

I started the car, backed it up, pulled forward turning to the left to go down a driveway when the car unexpectedly accelerated. I stomped on the brake but the car did not stop. I flew out of the driveway, across the street and hit 3 trees and a rock before the car stopped.

RX 350

  • miles
I bought a new Lexus rx 350 in August 2010 and had a collision on the third day driving the car. I was at a parking lot waiting for a parking space. The engine would shut down. When I saw a parking space available, I started the engine by pressing the engine button without pressing the brake pedal (you don't need to press the brake when you use a key to start the engine). I did not know by doing that, I only started the radio and air conditioning but not the engine itself. I then pressed the brake pedal and shifted to the driving gear. At that time, another car was pulling into the parking lot. I was going to stop my car to wait for the other car to pass by me. I pressed the brake but the car did not stop and kept going forward because the road is a little steep. I felt that I had no control of the car - both the brake and power steering. My car finally stopped after hitting an embankment in the parking lot. There was damage to the front bumper and scratches on the side. Total damage is more than $2,000. Went to the dealership and was told the rx 350 was designed in that way - if you press the start button without pressing the brake pedal, the engine won't start, but you are able to shift the gear to driving if you press the brake at this time. It can be very dangerous because the power steering and brake will not work properly if the engine is not started.
