Vehicle while driving at speed of 30 to 50 miles an hour suddenly has single wheeled front breaking on left wheel or right wheel all of a sudden. Tends to feel like what the braking system does during the activation of the vehicle skid control system while driving on slippery surfaces in winter light conditions. This also happens when the vehicle is put into reverse after first starting engine, shifting into reverse and backing up short distance. The fact that the vehicle does it while driving at speeds of 30 to 50 miles an hour is quite dangerous due to the fact that it happens all the sudden and dry payment. This happened at highway speed's in traffic with us could have caused an accident though I was able to safely pull over.

Vehicle locks up on right hand curves over 30 mph causing vehicle to slide into other lanes. Very dangerous condition which intermittent and unpredictable. Similar problems with same make, model and year across the web.

Several times now the vsc (electronic vehicle stability control) engages at very inappropriate times nearly resulting in a collision or being pulled off the road. It happened on highways, in clear weather, and almost always on a very slight turn. The speed has varied between 45 - 65 when this occurred. I want to stress that this was in 70 degree weather. No rain. No snow. No ice. There was zero traction slippage that could have contributed to this engaging. The vehicle nearly stops and we have been fortunate to not be rear ended by semi-trucks on multiple occasions. There is a tremendous amount of complaints about this happening from Lexus LX470 owners, but with very little success in identifying and fixing the problem from Lexus dealerships and corporate. Please investigate this and require a mandatory recall from Lexus before someone is killed.

The above VIN is for a vehicle that I own but have owned for only a couple of weeks. It has not experienced any safety issues over the short period that I have owned it. Since I purchased the car I have become aware that similar 2000 and 2001 model years Lx470S have experienced vehicle stability control (vsc) problems that seem to represent a safety concern. I have submitted a copy of a thread on a Lexus owner forum that describes the issue - which is often described as terrifying, or words to that effect, by those that have experienced it. This LX470 problem described seems to be very similar to the vehicle stability control problems that have been experienced on the 2001 and 2002 Toyota sequoia - for which I understand the NHTSA has opened an investigation. It is my understanding that the two Toyota stability control systems are very similar, and of course the timeframes are very similar. (the 2000 model year was the first year of vsc on the LX470. 2001 was the first model year for the sequoia.) I am making this submission only to make the NHTSA aware of the possibility of interrelation between the sequoia and LX470 problems.

I own a LX470 2000 with about 148,000 miles. Over the last couple of months, I have experienced 8 different times with the traction control problems as describing here. I was traveling at 65mph on a straight dry road my vsc warning light and audible alarm came on and vehicle began swerving violently back and forth apparently due to left and right brakes engaging alternately. Happened a few more times while driving at 35-40 mph. Every single occurrence, the system engaged randomly without warning and the steering wheel pulled to the right and unable to control the vehicle until the speed dropped to about 20mph. The duration of each occurrence has been from a couple seconds to 10 seconds. This has caused a lot of safety concerns and frustrations because the dealership and independent mechanics don't have a clue how to fix it. Please help in identifying the faulty component(s).
