general problems of the 2004 Lexus GX470

I have a 2004 Gx470 SUV. Today I was in a parking lot, trying to back out and leave. With one foot on the accelerator, I found it stuck, which was odd, as I had not experienced it before. So I pressed on it again, I thought, lightly. I was taken completely by surprise, as I seemed to have flown backwards, as I have a v8 engine, my acceleration was quick and my car immediately rammed into 2 parked cars behind me. I was in a state of shock and very scared, since it was so fast and sudden. Has anyone else experienced anything like this before? thank you.

Speedometer and tachometer gauges do not work properly. When the vehicle is turned on, will either activate right away or flicker or do nothing. This is an intermittent problem and is hard to diagnose or even fix. Have seen on Lexus forums this is a common problem and seems many of us are driving "speed blind". I have already had the cluster sent out and "repaired", only to have problem come back. I feel this problem is dangerous and the manufacturer needs to be held accountable.

Problem with vsc on my 2004 Lexus Gx470. I was driving from a ski resort on snow covered road at approx 35-37 mph. The front right wheel hit a pothole and the rear of the vehicle shot sideways and we were headed off the road to the right, then traction control or something kicked in and we shot into oncoming traffic. I tried to steer back into our lane and the rear left again sent us into a sideways skid across the right lane and headed off of the road until the right rear hit a pole. The car continued to move and shot us back into the right traffic lane and I was able to finally gain control and pull over. I had no control of the vehicle and we veered back and forth across the highway for several yards. I have driven in winter conditions for years and have been in slides before, but never where the car changed direction and veered back and forth instead of maintaining the slide trajectory. I am convinced that the sensors are wrong or something is wrong with the vsc and reported my concern to my insurance company and also to the Lexus dealership. I took the vehicle to Lexus and had them run full diagnostic, including zero point/yaw rate. They reported that there were no issues with the vsc. The tires and brakes checked out too. I have only had this vehicle serviced by Lexus, even oil changes. I have been searching this site and others for similar esc/vsc complaints and have found a few, then when the announcement about the vsc problems with the new Lexus GX came out, I knew I should report this. There should be an investigation of all Lexus GX vsc systems - whether they develop flaws over time or if there is some issue inherent with the system that causes the uncontrolled skids. This is the second time the car has gone into an uncontrolled slide - the first time there were no damages.

My Lexus GX 470 has accelerated uncontrollably since jan7, 2010 (first occurrence) and last occurrence March 12, 2010 . It generally occurs at light throttle from a stop and turning left at intersections and is compounded by a loss of electronic stability control also on wet pavement. Thus far, I have been able to react quickly enough to keep speeds under 60 mph. My wife and daughter have not been so fortunate and will not drive in and /or be a passenger in the vehicle. I'm handicapped and had a service dog who was killed in one of the crashes. If a neck can be broken then we are dealing with a very dangerous situation. I am a former Toyota executive engineer/ chief engineer for 8 years and have a huge amount of knowledge in this subject , such as program retention of ecm and denso throttle. Toyota knew of these electronic problems beginning in 2002 how many deaths in a Lexus GX 470 , before a recall occurs?????????.
