SITUATION

BMWeBay logo AG is conducting a Voluntary Safety Recall (effective July 8, 2021) on a small number of Model Year 2018 – 2019 BMWeBay logo vehicles that were produced between December 4, 2017 and June 3, 2019.

The CIS (Capacitive Interior Sensing) Mat, which detects the presence of a front passenger for front air bag deployment, may not function properly in certain limited circumstances.  If this were to occur, the air bag warning lamp would not illuminate.  In a crash, the front passenger air bag may not deploy, which could increase the risk of injury.  The CIS mat will need to be replaced.

The Recall Notice and Q&A have been attached for further information.

 

CAUSE

Due to an incorrect mounting of the seat cover, one or more of the hog rings (clamps) could contact the seat heating cable harness near the area of the seat cushion and thigh support.  Over time, this could affect CIS Mat functionality.  Hog rings are small metal clamps which fasten the seat cover to the seat frame.

 

CORRECTION

Replace the front passenger seat cushion which contains the CIS mat.

 

PROCEDURE

  1. Replace the seat occupancy mat for the front passenger seat in accordance with repair instructions REPP-6577611.

 

  1. Note: There is a changed procedure for clamping when installing the front seat cover- the new procedure below has not yet been incorporated into the repair instructions.

 

For section: Installing the seat cover for the front seat REP-TAT-P-5216-02-G01_3 New: The sequence in which the hog ring clamps are installed must be observed.

First clamp items 1-3, then clamp the area of the cable outlet 4 to prevent the seat heater line from being contacted and/or damaged by clamps.

 

  1. After reinstalling the seat cover, the seat occupancy mat (CIS) must be released with ISTA servicefunction:
