Chevrolet, GMC and Cadillac 6.2L V8 engines may fail

NHTSA campaign 25V274000 · Reported 2025-04-24 · General Motors, LLC

high How serious is it? About this label

Serious, because a sudden engine failure can leave you without power and lead to a crash; the notice does not say to stop driving, but get the inspection done promptly.

What's wrong, in plain English

These full-size trucks and SUVs have the 6.2-liter V8 gas engine. Some were built with faulty connecting rods or crankshafts — heavy internal parts that keep the engine turning. Those parts can break, damaging the engine badly enough that it quits. Dealers will inspect your engine and repair or replace it if needed. If it passes inspection, they will switch it to a thicker oil, put on a new oil filter and oil fill cap, and update your owner's manual. All free.

What you should do

1. Enter your VIN at nhtsa.gov/recalls to confirm your vehicle is affected.
2. Contact your dealer, or call Cadillac at 1-800-333-4223, Chevrolet at 1-800-222-1020, or GMC at 1-800-462-8782, and reference recall N252494000.
3. Schedule the engine inspection — the inspection and any repair or replacement are free.
