I WAS DRIVING DOWN THE ROAD AND NOTICED THE CLUTCH WASN'T "FEELING NORMAL." AS I SHIFTED INTO 3RD GEAR, THE CLUTCH PEDAL STUCK TO THE FLOOR AND WOULDN'T SPRING BACK.

STICKY AND SHINY DASHBOARD - MY DASHBOARD HAS BECOME EXTREMELY STICKY AND SHINY. STICKY TO THE POINT THAT IT SEEMS TO BE MELTING. SHINY TO THE POINT THAT MAKES IT DIFFICULT TO DRIVE DUE TO THE GLARE COMING OFF OF THE DASHBOARD. SUNGLASSES DO NOT EVEN HELP WITH THE GLARE. THE MATERIAL AROUND THE STEERING WHEEL HAS BECOME WILTED. THIS ALL STARTED ABOUT A YEAR AGO AND IS GETTING WORSE. *TR
