Some 2015 Mazda MX-5 Miata vehicles built before Aug. 7, 2015, may exhibit a grinding noise from around the clutch pedal when depressing it all the way down. This is caused by a stick-slip noise occurring at the contact point between the clutch pedal and the clutch pedal position switch plunger and/or the clutch pedal and the starter interlock switch plunger.
To prevent this grinding noise, two pieces of silicone pad is attached to the clutch pedal where the two switches contact.
