WHILE DRIVING ON A CITY STREET THE 2014 GMC SIERRA 6.2 L V8 LOST POWER AND STARTED RUNNING ROUGH AS APPROACHING AN INTERSECTION. I WAS ABLE TO STOP, AND REVERSE THE VEHICLE AWAY FROM THE INTERSECTION, TO GET OUT OF TRAFFIC. THE ENGINE LIGHT WAS FLASHING AND THE TRUCK SHUT DOWN, IT WAS UNABLE TO RESTART. THE TRUCK HAD UNDER 60,000 MILES ON IT AT THE TIME OF THE FIRST INCIDENT. IT WAS TOWED TO A GM DEALER SHOP FOR REPAIR. THIS FIRST INCIDENT TOOK PLACE IN AUGUST OF 2019. THE ROCKER ARM AND EXHAUST SPRING HAD TO BE REPLACED IN THE #2 CYLINDER, THE CYLINDER HEAD HAD TO BE REBUILT WITH A NEW HEAD. IN ADDITION THEY REPLACED 4 FUEL INJECTORS.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
