Federal regulators are examining continued GM engine failures following prior recall repairs, a development with implications for vehicle reliability and oversight. The National Highway Traffic Safety Administration opened Recall Query RQ26001 on January 16, 2026, focused on the 6.2L V8 L87 engine in Silverado, Tahoe, Escalade and related models. The review follows GM recall 25V-274 from April 2025, which addressed sediment buildup and crankshaft wear through higher-viscosity oil and engine replacements. Despite remedies, owners reported breakdowns, including incidents after repairs, and 36 complaints were noted alongside more than 28,000 earlier reports. The probe covers 597,630 U.S. vehicles, with 721,000 recalled globally. No crashes have been reported.
