GM Just RETIRED the 5.3 and 6.2 V8 - New Engines Left Everyone SPEECHLESS

V8s: a 5.7 liter and a 6.6 liter.

In this video I break down exactly why it happened, using the federal recall paperwork and the court filings instead of GM's marketing.

What we cover:

The 6.2L L87 recall — nearly 600,000 trucks and SUVs, 28,000 field reports, 14,000 total engine failures, 42 fires

What actually broke: debris in the connecting rods and crankshaft oil passages, plus crankshafts built out of spec

Why GM's official repair for a passing engine was an oil change from 0W-20 to 0W-40

The new federal investigation opened in January 2026 after 36 owners had engines fail AGAIN after the recall fix

The separate class action over AFM/DFM lifters on 5.3 and 6.2 engines back to 2014 — with $8,000 to $12,000 repair bills

What's inside the new 5.7L and 6.6L: forged pistons, forged rods, a redesigned oiling system, port and direct injection together

The engine codes L76 and L78, and the 1960s Corvette and Chevelle history GM is deliberately borrowing

The one detail that says the most: the new engines ship with 0W-30 instead of 0W-20 — a full grade thicker

The $1.6 billion GM spent across Flint, Tonawanda, Saginaw and St. Catharines

The question GM still refuses to answer: is cylinder deactivation gone or not?

Where I land: if you own a recalled 6.2, get the free inspection and the 10-year/150,000-mile extended warranty. If you own a 5.3 or 6.2 outside the recall, budget for a lifter job. If you're looking at a 2027, the engineering changes are real — but you'd be a first-year buyer on an all-new engine family.
