Big lunged powerplants cited to have potential for failure because of defective parts.

POTENTIAL of defective parts causing a complete failure has been cited for the reason why two big-lunged engines sold here in utility and sports utility vehicles have been subject to manufacturer recall.

The Ford Ranger ute and Everest SUV fitted with the 3.0-litre V6 ‘Lion’ turbodiesel (above) are subject to one action that has been officially notified.

According to the recall notice, the fault could result in a fracture to the left-hand engine camshaft, causing the vehicle to stall while driving.

The affected vehicles are stamped 2022 to 2025 models. Radio NZ has reported Ford NZ as citing that 647 vehicles here are subject to that action. A Ford NZ spokesman says that count represents just 1.4 percent of the total Ranger volume for that period.

The recall notice says: “Due to a manufacturing defect, the left-hand engine camshaft sprocket may fracture. As a result, the engine could stall, leading to a sudden loss of motive power whilst driving.”

The 6.2 litre petrol V8 that has gone into the Chevrolet Silverado and is cited for the GMC Yukon SUV that is about to come on sale here is also being subject to a manufacturer notification.

However at time of writing it is still unclear what action the distributor of those models here, General Motors Speciality Vehicles, will take.

General Motors in the United States has recalled 721,000 vehicles fitted with this engine due to defective parts leading to catastrophic failures including several injuries.

The action is for the ‘L87’ type that has placed in the Silverado and GMC Yukon between 2021 and 2024.

The recall was prompted after 39 complaints to US safety auditor, the National Highway Traffic Safety Administration, regarding engine failure, with drivers experiencing a sudden loss of power.

The failure is caused by damage to the crankshaft and connecting rods during the manufacturing process, with the recall mandating these parts be inspected – requiring the engine to be opened and rebuilt or replaced.
