Laguna Hills, CA – December 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.
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.
