Chronology :

At the end of January 2020, MBAG launched initial investigations based on a finding in a requalification test at a supplier. These investigations indicated a potential deviation in the material strength of components of the left rear seatback latch.

MBAG and the supplier investigated the issue further and found that the sub-supplier who produces the seat latch component had temporarily used the incorrect heat treatment. The processes on the sub-supplier’s heat treatment did not comply with the required production parameters. A review of production- and logistic documentation was performed by the supplier to determine the respective production range of the potentially affected seatback latches.

In parallel, MBAG conducted an evaluation of the strength forces of the lock as produced. MBAG’s analysis found the possibility that the latching mechanism may not maintain its intended strength under certain loads.

On May 29, 2020, MBAG determined that a potential safety consequence could not be ruled out.
