NHTSA expands GM engine recall to 2025–2026 models, affecting nearly 1 million vehicles
NHTSA has widened the GM engine recall probe to include 2025 and 2026 model years, increasing the potentially affected U.S. vehicles to 997,743 across eight models (Silverado 1500, Tahoe, Suburban, Sierra 1500, Yukon/Yukon XL, Escalade and Escalade ESV). The L87 6.2L V-8 engine’s reported defects in connecting rods/crankshaft could cause engine failure, prompting GM to recall 597,630 vehicles from 2021–2024. The recall remedies include an oil viscosity change (with a new cap and filter) or engine replacement if diagnosed as necessary; a 10-year or 150,000-mile coverage applies. Despite remedies, NHTSA reports post-remedy complaints (499 total; 473 oil-changes, 26 engine replacements; plus 191 post-production failures) and GM has logged 6,953 post-remedy complaints as investigations continue.
