GM Tightens Engine Quality Control Ahead of New Pickup Launch
Pickup owners typically discuss power, torque, and towing capabilities. However, what they don’t want to think about is whether their new vehicle’s engine will still be running after 100,000 miles. Unfortunately for General Motors, this question has become common among V8 owners, but future buyers may be able to avoid it.
The company is preparing for the launch of the updated Chevrolet Silverado and GMC Sierra in 2027. Reports indicate it is not only developing a new V8 engine but also taking measures to ensure buyers won’t worry over the next decade about whether this engine will cause further recalls, many of which have led to class-action lawsuits.
GM is tightening quality control on key components for the upcoming Gen 6 Small Block V8. Some critical parts and manufacturing processes are being brought back under GM’s direct control rather than being outsourced to external suppliers.
This comes just a year after GM recalled nearly 600,000 pickups and SUVs equipped with the 6.2-liter V8 engine. Investigators linked the engine failures to manufacturing defects and quality issues with internal components. This problem has become one of the company’s biggest reputational setbacks, making the timing of these changes no coincidence.

The new Silverado and Sierra are likely to replace the current 5.3-liter and 6.2-liter V8 engines with new 5.7-liter and 6.6-liter Small Block variants. A 6.7-liter version of this engine producing 535 horsepower for the 2027 Corvette was unveiled in March. GM has already invested significant funds in production, including $888 million in the Tonawanda plant to support the new V8 program. The engines will also be built at two other plants, one of which is in Canada.
Whether the new engine design and the return of manufacturing processes under direct control will guarantee flawless reliability remains to be seen. Engines earn their reputation on highways, construction sites, and during towing, and that takes time. But after the difficult years experienced by GM’s V8 engines, tightened control might be exactly what pickup buyers want to hear.

This move by GM demonstrates that the company is serious about restoring trust after massive recalls. Bringing production of critical components back under its own control could reduce risks associated with quality from external suppliers. At the same time, the real test will only come after the new engines begin operating in real-world conditions. The investment of nearly a billion dollars underscores GM’s long-term commitment to internal combustion engines, even in the era of electrification. For buyers torn between a gasoline and an electric pickup, this news could be a strong argument in favor of the traditional V8.
