2010-2015 CX-9 – OIL SEEPAGE FROM POWER STEERING OIL PRESSURE SWITCH

APPLICABLE MODEL(S)/VINS

2010-2015 CX-9

Abnormal steering feel and/or noise while driving the vehicle in freezing temperatures, however, there is no loss of steering control.

This may be due to oil seepage from the power steering oil pump pressure switch (A).

The oil seepage is caused by poor sealing of the oil pressure switch o-ring at low temperature. The shape and material of the o-ring has been changed to improve low temperature sealing performance.

REPAIR PROCEDURE

Replace the power steering oil pump pressure switch with a modified part according to the instructions on MS3 online or the Workshop Manual (section 06-14).
