BMW has issued a stop-sale and recall on M5, variants of the M8, X5 M, and X6 M because of a problem with the transmission wiring harness. The company already notified the National Highway Traffic Safety Administration of the problem, but the agency hasn't publicly published the info yet. Motor1.com reached out to BMW of North America for details on the issue. We first heard about the issue from a post on the Bimmerpost forums.

To fix the issue, technicians will replace the transmission wiring harness,  and they'll reroute it to a safer position. BMW will mail a letter to affected owners in February 2020 that will advise them of the recall and will ask them to schedule an appointment to repair the issue at a local dealer. 

There's bad news for anyone intending on buying one of these models, though. BMW can't sell any affected vehicles in dealer inventories until the repair is complete. "February is the expected time for transmission wiring harness replacements to begin," the company indicated.

"BMW is in the process of ensuring that the necessary tools, parts, and procedures are available prior to contacting owners to schedule an appointment with their authorized BMW center to have this important Safety Recall performed," the company's statement said.

Issue

Due to the location and routing of the transmission wiring harness, it could become damaged.

This could lead to a short circuit, affecting transmission function, and causes the vehicle to lose propulsion and to shift to Neutral while driving, increasing the risk of a crash.

If you notice that while driving the vehicle loses propulsion and the transmission shifts to Neutral, your vehicle may be experiencing this issue.
