BMW vehicles may unexpectedly shift into neutral

Laguna Hills, CA – Dec. 20, 2019 – BMW of North America LLC is recalling certain 2017-2019 2019-2020 M8 Gran Coupe, M8 Coupe, and M8 Convertible vehicles. The transmission wiring harness can be more easily damaged, causing an electrical short circuit.

The potential number of vehicles affected is estimated at 3,012.

The Defect

According to BMW, the transmission wiring harness can be damaged by both high temperatures and compression from the wiring harness mounting clip, resulting in an electrical short circuit in the transmission wiring harness. The defect is caused by mistakes in the setup of insulation material for the harness, routing, and some of the fastening points of the harness to the transmission housing. A short circuit could cause the vehicle to unexpectedly shift into Neutral while driving. The rapid loss of propulsion may cause a crash. No accidents have been reported that resulted from this defect.  

Timeline of Events

On September 24, 2019, a vehicle’s transmission unexpectedly shifted into Neutral at a BMW assembly plant. The vehicle could not shift back into drive.

Starting in October, BMW performed an engineering and assembly process review, as well as a field incident analysis. The field incident analysis found that the problem had occurred with 18 vehicles worldwide. Final analysis determined the cause of the problem.
