General Motors continues to grapple with persistent issues in its high-output L87 V8 engine platform. Despite launching a recall program last summer to replace faulty fuel injectors and update engine control software, the company has received over 3,500 new complaints of engine stalling, misfires and “limp-home” mode activations since November 2025. The National Highway Traffic Safety Administration (NHTSA) has opened an expanded investigation under PE26-012, citing concerns that the original fix may not fully address underlying injector seal failures and combustion chamber deposits. Early GM estimates put the incremental warranty and service campaign costs at $120 million, and internal projections warn of an additional $50 million in potential fines if NHTSA deems the remedy insufficient. Management has established a cross-functional task force to collaborate with supplier Delphi Injection Systems on redesigning the injector O-rings and implementing more rigorous end-of-line quality checks by Q3 2026.

Full-size pickup trucks remain the cornerstone of GM’s North American profitability, contributing over 40% of the corporation’s gross automotive profits in fiscal 2025. The Silverado series, refreshed in late 2024 with an updated chassis and improved MaxTow towing package, sold 267,000 units last year—up 6% year-over-year—while commanding an average transaction price roughly 15% above mid-cycle competitors. Internal sales data shows that Silverado High Country and LTZ models alone generated approximately $3.1 billion in adjusted operating income during the fourth quarter, offsetting margin pressures in the EV and compact crossover segments. With the upcoming launch of the ZR2 off-road variant in spring 2026, GM forecasts a further 2-3% uptick in full-size truck ASPs, reinforcing its leadership against Ford’s F-150 and Stellantis’s Ram 1500 in the high-margin pickup arena.
