FLOOR UNDER COVER FALLS OFF AFTER DRIVING ON SNOW AND
ICE

Bulletin No.: 09-039/18

Last Issued: 11/01/2018

DESCRIPTION
APPLICABLE MODEL(S)/VINS
2017-2018 CX-5
2018 CX-5 (Mexico spec.)
Some customers may notice the floor under cover No.2 falling off at the bolt (1) location after driving
through snow and/or ice. This may be caused by snow and/or ice accumulation under cover No. 2 (as
shown below).
This concern is caused because the bolt hole is too large for the bolt to hold the under cover when snow
and/or ice accumulates under the body. To eliminate this concern, the bolt hole diameter has been reduced.
