2016 MX-5 – GRINDING NOISE FROM CLUTCH PEDAL WHEN DEPRESSING
APPLICABLE MODEL(S)/VINS
2016 MX-5 vehicles with VINs lower than JM1ND******104047 (produced before August 7, 2015)
Grind 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 (A) between the clutch pedal (B) and the clutch pedal position switch (C) plunger and/or the clutch pedal and the starter interlock switch (D) plunger (F: Vehicle front).
To prevent the stick-slip noise from occurring, two pieces of silicon pad have been attached to the clutch pedal where the two switches contact.
REPAIR PROCEDURE
- Attach two pieces of silicone pad to the clutch pedal.
- Remove the clutch pedal position switch and the starter interlock switch according to the instructions on MS3 online or the Workshop Manual (section 09-10).
- Degrease the surfaces of the clutch pedal where the silicone pads will be applied for the clutch pedal position switch (A) and the starter interlock switch (B).
F: Vehicle front
U: Upside
- Peel off the protective foil and apply the silicon pad to the clutch pedal as shown below (the clutch pedal position switch and the starter interlock switch sides).
CLUTCH PEDAL POSITION SWITCH side
A: Align one corner of the silicon pad with this point
B: View from bottom
C: Contact point of switch plunger
S: Silicon pad
STARTER INTERLOCK SWITCH side
A: Align one corner of the silicon pad with this point
