2010-2015 CX-9 – UNUSUAL RATTLE / BUZZ TYPE NOISE FROM PRE-SILENCER
APPLICABLE MODEL(S)/VINS
2010-2015 CX-9
Unusual rattle/buzzing type noise from the presilencer when driving at approximately 1800 rpm.
The lower (rear-side) of the pre-silencer may be thermally deformed due to insufficient rigidity (fewer weld spots). The deformed portion may resonate exhaust gas pulsations, which causes noise.
A reinforced plate has been added to the pre-silencer to increase the rigidity, thereby eliminating deformation.
REPAIR PROCEDURE
- Replace the presilencer (A). Refer to MS3 online or Workshop Manual (section 01-15).
