When I was driving my Lexus GX470 (2003) with my family on a local street at around 35 mph, my vehicle suddenly stopped by itself. The brakes engage by itself and the vehicle stability control activated with beeps. Fortunately, no one was behind me. I took my car to the local mechanic, he checked the brakes, calipers..etc, he said everything is fine but he couldn?T find any reason why it happened, he asked me to contact Lexus dealer. I called the Lexus dealer service center, I explained the service representative about what happened, he told me to check the brake calipers, I told him the mechanic already checked it. Anyway, even the Lexus dealer couldn't explain why it happened.

I was driving my 2003 Lexus GX470 on my way to the hospital with my three year old son ' who was experiencing breathing problems. I lost control of the SUV near the exit for the hospital ' as I was preparing to take the exit from the freeway. The vehicle went off-balance and did a 360 degree rollover from the exit ramp. I ended up in the median between the off ramp and the on ramp. My son and I were intact after the accident. The vehicle behaved erratically during the episode ' and I could not figure out what was happening with the controls. I would like for NHTSA to look into the stability system of this vehicle ' based on this experience and recent news of similar vehicles from Lexus.

We were proceeding to make a R.H. turn from on two lane road to another in a 2003 Lexus Gx when the accelerator stuck and ESC completely failed. Although I pushed transmission's lever in neutral. The rear end skidded outward and no ESC or ABS was evident. I steered into skid and then steered into ditch to avoid offset collision with oncoming traffic. And skidded into ditch on opposite side of road. Severe concussion and amnesia for driver as dead slammed into driver's window. Passenger suffered left leg injury. I reported two prior incidents to NHTSA Jan 9, 2010, etc and no response. Now I am going public and to senator rockerfeller that NHTSA is totally unresponsive.

I was traveling West on a two lane paved road (sutton road) near sutton school. Weather was snowing and road conditions slippery when my accererator failed to return to idle position. I applied brakes as I was approaching a vehicle in front of me traveling in the same direction. The electronic stability control failed to maintain straight direction as per design intent and manuals. Front began sliding to left and rear of vehicle began sliding to right. I ncreased brake pressure and steered into th skid, to the right. I was able to miss the contact with any other vehicles and or damage any property, but did end up sliding into a ditch off of the road. With the impact resulting in the death of my service dog. As I am handicapped. No damage to my vehicle, but no I am virtually immobile with the loss if my dear service dog.
