We have three 2019 Nissan Frontier pickups in our fleet that have all recently had the same problem. A engine valve misfire on cylinder 3 on all three trucks. This has caused the trucks to shake, idle rough, and have loss of power while driving. Two independent mechanics have inspected the trucks and have replaced multiple parts to try and fix the problem, however, it has been recommended that all three trucks have the engine replaced. The check engine light did activate on the dash when the problem first began in each truck.

The dealer has read the code but refuses to work on it without a brand new OEM battery. This first occurred with an OEM battery, and I replaced with one and the problem still happens. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Only the dealership, who was useless. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No indicators the driver would be able to see. The check engine light is NOT on. When scanned via the OBD2 sensor, the Nissan specific code is thrown, but you obviously have to have the correct tool to see this.
