ALABAMA (WHNT) — General Motors has recalled nearly 600,000 vehicles for possibly defective engines that are failing, increasing the risk of a crash.
The National Highway Traffic Safety Administration posted on April 24 that GM is recalling certain 2021-2024 vehicles equipped with a 6.2L V8 gas engine. GM says the connecting rod and/or crankshaft engine components may have manufacturing defects that could lead to engine damage and engine failure.
In total, the recall could affect roughly 597,571 vehicles.
The following vehicle models are named in the recall:
- 2021-2024 Cadillac Escalade
- 2021-2024 Cadillac Escalade ESV
- 2021-2024 Chevrolet Silverado 1500
- 2021-2024 Chevrolet Suburban
- 2021-2024 Chevrolet Tahoe
- 2021-2024 GMC Sierra 1500
- 2021-2024 GMC Yukon
- 2021-2024 GMC Yukon XL
The report on the NHTSA website says there are 79,747 Cadillac Escalades affected, 46,280 Cadillac Escalade ESVs affected, 107,244 Chevrolet Silverado 1500s affected, 22,162 Chevrolet Suburbans affected, 44,802 Chevrolet Tahoes affected, 153,630 GMC Sierra 1500s affected, 82,832 GMC Yukons affected and 60,933 GMC Yukon XLs affected.
The NHTSA report says the engine teardown analysis identified two primary root causes, both of which are attributable to supplier manufacturing and quality issues:
- Rod-bearing damage from sediment on connecting rods and crankshaft oil galleries
- Out-of-specification crankshaft dimensions and surface finish
Prior to engine failure, drivers may be alerted to the issue by hearing a knocking, banding or other unusual engine noises, illumination of the check engine light and/or engine-performance issues including hesitation, high RPMs, abnormal shifting, reduced propulsion or a no-start condition.
The investigation into this incident started on Jan. 16 when GM opened a product investigation following a NHTSA notification that alleged the engine failure on the vehicles listed above.
GM’s investigation identified over 28,000 field complaints or incidents in the U.S. potentially related to failure of the L87 engine due to crankshaft, connecting rod, or engine bearing failure, of which 14,332 involved allegations of loss of propulsion. These field complaints were received between April 29, 2021, and February 3, 2025.
“GM identified 12 potentially related alleged crashes and 12 potentially related alleged injuries in the U.S.; all specifically alleged injuries were minor or non-physical, and most were not crash-related. GM also identified 42 potentially related fire allegations in the U.S., but in the majority of these cases, the causation of these incidents are unclear and the alleged fire damage is contained to the engine compartment and consistent with damage that can occur, in rare instances, during engine failure,” NHTSA said.

These vehicle model owners will receive letters from GM around June 9. GM dealers will inspect vehicle engines and make any repairs or replacements. Vehicles that pass inspection will receive higher viscosity oil, a new oil filter, a new filter cap and an updated owner’s manual.
Per GM, owners will be reimbursed for repairs.
