Summary

15684 - service update. This bulletin provides a service procedure to inspect and, if necessary, reposition the main engine-wiring harness on certain 2016 model year cadillac ats-v vehicles. In some of these vehicles, the orientation of the main-engine wiring harness could cause the wires to contact and chafe against the right-front valve cover bolt and washer. If the engine-wiring harness insulation is compromised, the vehicle’s tachometer, powertrain, and automatic-braking systems could be effected. While this condition could—if uncorrected—cause a loss of propulsion or the activation of the automatic braking system, gm has no reports indicating that either event has occurred on a vehicle in the field.

Owners of these vehicles have filed 1 complaints in the engine category.
