This is to notify you of a Recall Campaign launch regarding the Occupant Classification System on 129 Model Year MY2015-2018 CLA-Class (117 platform) vehicles.  The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs will be flagged in VMI as “OPEN” on July 25, 2020.
Background
Issue		Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY15-18 CLA-Class (117 platform) vehicles, the calibration of the Occupant Classification System (OCS) for the front passenger seat might not meet current production specifications. If the OCS is not calibrated according to production specifications, an installed child seat might be classified as an occupant, or a small and light occupant might be classified as a child seat. Therefore, the passenger airbag might be activated despite a mounted child seat. Conversely, the front passenger airbag might be deactivated despite an occupant sitting on the front passenger seat. Both cases would increase the risk of injuries to the passenger in case of a crash necessitating an airbag deployment.
What We’re Doing		MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer, will replace the passenger seat cushion on the affected vehicles
Parts		Parts are available and can be ordered as necessary.
Vehicles Affected

What will your DEALER DO?	An authorized Mercedes-Benz dealer will replace the passenger seat cushion on the affected vehicles.  This service will be provided free of charge.  We are dedicated to always delivering the best customer experience, and respect for your time is a top priority.  While the minimum repair time is approximately 2 hours, your dealer can provide you with a better estimate of the overall time for this service visit.  As a matter of normal service process, an authorized Mercedes-Benz dealer will also check for other repair measures which might be applicable to your vehicle which may increase the required working time.
What should YOU DO?	For additional information and to schedule an appointment, please contact your preferred authorized Mercedes-Benz dealer at your earliest convenience. To locate authorized dealers see  www.MBUSA.com/recall.  Please mention you are scheduling an appointment to have the front passenger seat replaced under Recall Campaign # 2020060012.

February, 2020

Dear Mercedes-Benz Owner,

Mercedes-Benz Part 573 Submission
Original Submitted to Portal December 13, 2019
Chronology-Only section
Supplement to Original Submission

 

Chronology of Defect/Noncompliance Determination

In September 2019, MBAG’s product regulation team became aware of a supplier’s report from

November 2017, which was believed to be related to a recall already decided in August 2018 (18V-514). The report states that a software change had been made earlier in November 2017. This software change related to the calibration of the occupant classification system on seats provided by that supplier. The supplier reported that within its facilities, a seat is placed into a Force Application Machine (FAM), which determines the correct calibration for the seat based on the seat variant and various physical dimensions. There was a possibility that if a seat had been rejected or if the calibration was incomplete, the FAM would nonetheless retain the information relevant to that seat and apply it to the following seat, which could be of a different seat variant, therefore causing a wrong calibration. In the thorough analysis of the report, it became apparent that it had a different root cause than the recall conducted in 2018. After confirming that the 2018 recall did not involve the same vehicle population, MBAG promptly investigated the potential impact of the FAM calibration concerns. This included the extent to which the passenger airbag status displays were accurately capturing the occupancy status of the potentially affected seats and the extent to which seats may have received an accurate calibration even if the calibration was set for the previous seat in the FAM.  MBAG has received no reports of any field incidents – including customer complaints, warranty claims or field reports – either in the US or abroad, suggesting that the airbag status display was not accurately reflecting the occupancy status of passenger seats.

On December 6, 2019, MBAG determined that a safety relevance could not be ruled out and decided to conduct a global recall with regard to vehicles potentially impacted by the FAM calibration concerns, which includes 129 vehicles in the US market.
