Hi everyone, Firstly: thank you for the suggestions ! Really great to read your ideas on this problem. I finally got the car to mechanic and asked him to change/flush the brake fluid...he did and so far...no unexpected TRAC light occurences. He did scan for codes and found a 45 for primary throttle position sensor (tps), 51 for engine control module (ecu)...but, my ck engine light never comes on and a 19 found on the right side of the ABS I believe he said...he has nothing for this code ! Does anyone know what this is for ? He did say IF the light came on I would have to go to Lexus for repairs. So, I am keeping my fingers crossed at this point but the brake fluid change, which he said should be done every 2-3 yrs, has been a good thing. Thanks again, will keep reading and writing.

This is my first post....My trac light comes and goes without any connection to road condition...lately it has just stayed on and the only way to get it to turn off is to restart car...I even turned off the TRAC OFF button and it stays off ! How worried should I be....how bad is this ? Thank you for any help, ideas.
