DRIVER SEAT GRADUALLY MOVES DOWN BY ITSELF

2013-2015 CX-5 - DRIVER SEAT GRADUALLY MOVES DOWN BY ITSELF

BULLETIN NOTE
• This bulletin supersedes the previous bulletin 09-019/14 issued 03/12/14 and 09-010/13 issued 04/10/13, 10/
31/13 and 12/16/13. The APPLICABLE MODEL(S)/VINS, DESCRIPTION, REPAIR PROCEDURE, PART(S)
and WARRANTY INFORMATION has been revised.
• Changes are noted below in Red beside the change bar.

APPLICABLE MODEL(S)/VINS
2013-2015 CX-5 vehicles without power seats with VINs lower than JM3KE******548562 (produced before Oct.
31, 2014)

DESCRIPTION
Some vehicles (without power seats) may exhibit a driver seat that gradually moves down by itself. This concern may be caused when a load, which is applied to the seat during braking, exceeds a certain level that could
impact the retaining mechanism of the seat lifter causing the seat to gradually move downward.
To eliminate this concern, the play in the lift mechanism gears has been reduced.
Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR OUTLINE
1. Verify the customer concern.
NOTE: Ensure the customer is not bumping or touching the adjuster by mistake when entering or exiting
the vehicle.
2. If the customer complaint has been confirmed, replace the driver seat lift unit with the newly established service parts kit according to the “SEAT LIFT UNIT (SERVICE PARTS KIT) REPLACEMENT PROCEDURE”.
NOTE: Replace the following parts (specified as “Replacement Parts” in the Workshop Manual) with new
ones:
• Front seat side cover clip
• Recliner knob (with lever type recliner knob)
• Lifter knob
