Rx 300 alarm/beep

[MrsT]

The beeping I have is more of an alarm and is happening when I'm taking curves. Sometimes switching lanes and I've noticed if the steering wheel stays farther right/left than a certain point it will continue to beep until I am able to somehow adjust the wheel.  There are some parts of my local highway system that I drive where the beep is continuous because there is no way to move the steering wheel in the opposite direction to get the beep to stop.  Also the steering wheel itself seems "loose".  I'm not sure if that is contributing or not.  2002 Lexus RX300.  I have been unsuccessful in figuring out what is going on. Personal replies to email would be great.  mscandy4@hotmail.com since I'm not sure I can find my way back here.

I suspect the beeping is related to a problem with what was called Vehicle Skid Control (VSC) back in 2002.  It's since been re-branded as Vehicle Stability Control.  How it works is explained at https://drivers.lexus.com/lexusdrivers/experiences/experiences-details/ART2654

A loose steering wheel is worrisome and could be a symptom of the problem.  We've had vehicles with VSC for almost 20 years and have never had the warning beeping occur when changing lanes or rounding curves on dry, smooth pavement during normal driving.  It's occurred mainly on rain, ice or snow slick pavement and a few times on loose gravel when I was driving VERY hard and pushing the vehicle to the limit.

This could be a dangerous situation.  I suggest that you have a professional (e.g. Lexus dealership technician) diagnose the problem.
