NHTSA Probes Post-Recall Failures in GM's 6.2L V8
TL;DR Summary
GM’s recall of nearly 600,000 L87 6.2L V8 engines included thicker oil and other fixes, but hundreds of engines have failed after the repair, prompting a NHTSA Engineering Analysis that now covers almost 1 million engines through 2026. Reports show 499 post-recall failures (473 after thicker oil, 26 replacement engines) and 6,953 post-recall GM reports, raising questions about the fix’s effectiveness as GM moves to a 6.6L engine for 2027 models.
