"General Motors has issued significant recalls for both engine and transmission issues affecting its full-size trucks and SUVs.
Engine Recalls
Affected Models: 2021-2024 Cadillac Escalade, Chevrolet Silverado 1500/Suburban/Tahoe, and GMC Sierra 1500/Yukon equipped with the 6.2L L87 V8 engine.
Issue: Manufacturing defects in connecting rods and/or crankshafts can lead to sudden engine failure, increasing crash risk.
Remedy: Dealers will inspect the engine for repair or replacement free of charge.
Status: While the initial recall covered nearly 600,000 vehicles, NHTSA has opened a new investigation into post-recall failures, with owner notifications for the initial recall mailed in June 2025.
Transmission Recalls
Affected Models: 2022 model year Chevrolet Tahoe/Suburban, GMC Yukon/Yukon XL, and Cadillac Escalade/ESV with 10-speed transmissions featuring Electronic Transmission Range Select (ETRS). Additionally, 1,055 2020-2022 Silverado and Sierra pickups are recalled because they received incorrect software during a previous repair.
Issue: Excessive wear in the transmission control valve can cause gradual pressure loss, harsh shifting, or rare but serious rear wheel lockup.
Remedy: Dealers will install new Transmission Control Module (TCM) software that monitors valve wear. If a fault is detected, the transmission limits itself to fifth gear to prevent lockup."
