This was the problem with my 2006 GS. The battery was leaking gas that affected the power steering ECU which then set off a chain reaction of computer failure. All steering related items failed and the associated lights lit up, CHECK VSC showed up, CHECK 4WD,........everything but the check engine light. I was able to get the car to Lexus with the lights on and they were able to read the CAN-BUS codes (different from usual OBD coded associated with emissions and check engine light). In addition to my problems, the computer failures basically caused the ECUs to throw up. This in turn caused some "odditiies". My speedometer worked but the temperature guage dropped to C, the light behind the gear selector went out and the outside temperature would read "E".
When the battery was load tested, it failed. It had enough juice to always start the car, but it would heat up and emit a gas that affected the steering ECU and then start a chain reaction of computer related issues. The steering ECU is located directly under the battery case. Lexus is aware that there is a problem with the original Panasonic batteries.
Have your battery load tested and replaced if necessary.
