I have been experiencing an unusual problem with my 2005 Lexus GX 470. The Engine check; VSC TRAC, KDSS, RSCA OFF lights come ON, especially after the car has been parked for a while. The Lexus dealer has checked and reset the lights on three occasions and found no problem with any of the systems. What could be the source of this problem? has anyone ever experienced this problem before? I love my GX but this is driving me nuts. Help!!!!

Dear Fellow Gx owners,

Finally Lexus managed to find the problem to the warning lights. It came from a petrol pipe that was damaged and part licking petrol fumes. This would trigger the engine light first that would also affect the other. The pipe was replaced under warranty. Please note this for future reference.
