NHTSA complaint #11764883

Owner complaint summary

While the vehicle was being driven on a busy city street, it suddenly lost the ability to accelerate. The vehicle displayed multiple warning messages, including “Warning Low Oil Pressure — Stop Vehicle” and a collision warning. The accelerator no longer operated the vehicle normally. After the vehicle was shut off, it would not restart. The vehicle was taken to a Nissan dealership. The dealership initially could not communicate with the vehicle’s CAN system. After approximately three days of diagnosis, the dealer determined that there was a short to ground in the vehicle’s main wiring harness.There was no accident or other known event that caused the failure. The vehicle was operating normally before the incident. I am particularly concerned because the failure occurred while the vehicle was being driven and resulted in a sudden loss of acceleration. This created a potentially dangerous loss of propulsion. I am asking NHTSA to record and review this incident as a potential safety-related defect involving premature failure of the main wiring harness and the resulting loss of vehicle propulsion and CAN communication. I do not know whether this is an isolated failure or a broader design/manufacturing problem. I am reporting it so that NHTSA can determine whether similar complaints exist involving this vehicle, wiring harness, or failure mode. Note-Main harness replacement cost was approximately $4,450. In my opinion the work was diagnosed incompletely and the fauly could have been traced to individual wire (s) or electronic module. Photos show no obvious burning.
