General Motors is facing renewed scrutiny from the U.S. National Highway Traffic Safety Administration after reports that L87 V8 engines continued to fail in certain full-size pickup and SUV models even after a 2023 recall fix. The NHTSA opened a preliminary investigation into approximately 597,571 vehicles spanning 2021 through 2024 model years, focusing on persistent connecting rod bearing wear that can lead to catastrophic engine failure. GM has disclosed that warranty and recall costs related to the L87 engine issue have already exceeded $350 million and could rise further if additional repairs or broader warranty extensions are required. Investors are closely watching GM’s potential liability and the risk of expanded recalls or civil penalties, especially given that this is the second major engine-related recall for the company in under two years.

Despite regulatory headwinds, GM closed 2025 as the U.S. auto industry leader in total light-vehicle sales, achieving a 6% year-over-year increase driven by strong demand across all price tiers. The Chevrolet Silverado and GMC Sierra full-size pickups delivered their best combined annual total in two decades, marking GM’s sixth consecutive year leading the segment. GM’s four brands each registered growth: GMC set a third straight annual record, Cadillac posted its best sales in ten years, and Chevrolet and Buick moved nearly 700,000 entry-level units priced under $30,000. Notably, GM achieved these results while maintaining incentives below the industry average, supporting a consolidated gross margin of approximately 9.4%. This combination of volume growth, margin discipline and affordability positions GM to capitalize on market share opportunities as electric vehicle adoption expands and competitive pressures intensify.

GM secured the position of second-best-selling electric vehicle brand in the U.S., behind only Tesla, by delivering over 140,000 EV units across its Chevrolet Bolt, Cadillac Lyriq and GMC Sierra EV lines. This performance came despite the expiration of the $7,500 federal EV tax credit for certain models and rising global competition from Chinese automakers entering North American markets. GM has invested roughly $35 billion in EV and battery production capacity through 2025, including the recent groundbreaking of a new Ultium battery plant in Michigan. Management forecasts that EVs will represent 20% of GM’s total volume by 2027, underpinned by planned launches of five new electric models and a targeted reduction in battery cell costs to below $100 per kilowatt-hour.
