THE INDICATIOR LIGHT FOR LOW TIRE PRESSURE COMES ON BUT NO WARNING CHIME IS HEARED. THIS CAN BE VERY BAD WHEN DRIVING ON THE INTERSTATE. THE TIRE WAS LOOSING PRESSURE WITHOUT ME KNOWING AND I HAD NO CLUE UNTIL THE VEHICLE RAN OFF THE ROAD DUE TO NOT BEING ABLE TO CONTROL IT. THE CHIME NEVER WENT OFF. SAME WITH AN OVER HEATING ISSUE THE LIGHT CAME ON BUT I DID NOT KNOW IT WAS OVER HEATING UNTIL IT STATED SHAVING AND STEAMING AND I LOOKED AT THE DASH TO SEE THE LIGHT ON.
