Owners Report Their GM 6.2L V8s Are Still Failing Even After Recall Repairs
Jalopnik • • business
Key Points:
- General Motors recalled nearly 600,000 L87 6.2-liter V8 engines due to failures in crankshafts, connecting rods, and engine bearings, affecting popular models like the Chevy Silverado and Cadillac Escalade.
- The recall involved inspecting and repairing engines, switching oil from 0W-20 to thicker 0W-40, and updating oil filters and manuals, aiming to prevent further damage from manufacturing defects.
- Despite these measures, the National Highway Traffic Safety Administration (NHTSA) has received hundreds of reports of additional engine failures post-recall, including failures in replacement engines built after the recall period.
- NHTSA has launched an Engineering Analysis to investigate the effectiveness of the recall and is expanding the probe to nearly one million engines through 2026, raising concerns about the recall's success.
- While no new recall has been issued yet, the ongoing investigation suggests a potential additional fix may be forthcoming to address persistent engine failure issues.
