The contact owns a 2015 Chevrolet Equinox. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. While the vehicle was stopped at a traffic light, the vehicle jerked and idled roughly and nearly stalled. The vehicle was taken to Auto Zone to be diagnosed. The contact was provided with DTC P0172. The vehicle was not repaired. Several days later, the vehicle was taken for an oil change, and transmission fluid was flushed and refilled. The contact stated that on a separate occasion, a week after the oil change, the check engine warning light illuminated. The contact took the vehicle back to Auto Zone to be diagnosed. The contact was provided with the same DTC: P0172. The vehicle was not repaired. The contact stated that the failure persisted. The vehicle was then taken to the dealer. The contact could not leave the vehicle at the dealer. The contact spoke with one of the mechanics at the dealer, who suggested that the high-pressure fuel pump may be the cause of the failure. Several days later, the contact took the vehicle to the dealer, where it was diagnosed and determined that the high-pressure fuel pump had failed and needed to be replaced. The contact was informed that fuel had leaked into the engine through the PCP valve and caused the fuel to run rich. The vehicle was not repaired. The vehicle remained at the dealer unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 197,000.
