“TL* THE CONTACT OWNS A 2014 LEXUS LS460. WHILE DRIVING APPROXIMATELY 30 MPH, A BURNT ODOR DEVELOPED INSIDE THE CABIN OF THE VEHICLE. THE CONTACT DID NOT KNOW THE ORIGIN OF THE ODOR. THE CONTACT NOTICED SMOKE COMING FROM THE PASSENGER SIDE DOOR PANEL NEAR THE LOCATION OF THE COURTESY LIGHT. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING, BUT NO DEFECTS WERE FOUND THAT MAY HAVE CAUSED THE SMALL FIRE AROUND THE LIGHT, WHICH DAMAGED THE LEATHER ON THE DOOR PANEL.
