APPLICABLE MODEL(S)/VINS

2007-2012 CX-7 4WD vehicles with VINS lower than JM3ER******422257 (produced before Dec. 22, 2011)

DESCRIPTION

Some customers may notice a vibration from the floor and/or steering wheel during acceleration at approx. 50 mph. To eliminate this concern, the amount of velocity joint grease was increased during mass-production.

Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE

1. Before test driving the vehicle, remove the drivers side front scuff plate (inner) and front side trim to gain access to the 4WD control module.

2. Drive the vehicle to confirm the vibration occurs in 4WD.





3. Disconnect the connector (A) for the 4WD control module (B).

4. Test drive the vehicle again.

- If the vibration is gone, replace the propeller shaft with a new one according to the online instructions on MS3 or the Workshop Manual (section 03-15 PROPELLER SHAFT REMOVAL/INSTALLATION).

- If the vibration remains, continue troubleshooting according to the online instructions on M53 or the Workshop Manual.

5. Reconnect the 4WD control module connector and install the other parts in the reverse order of removal.

6. Connect the M-MDS and clear the DTCs (U0114.8 and/or U0114.20) that were stored when the 4WD control module connector was disconnected in Step 3.

7. Verify repair.
