Cadillac Escalade GMT900

6.2L V8, EcoTec3 architecture with AFM/DFM cylinder deactivation. 403-425 hp depending on calibration, 460 lb-ft from 4,100 rpm. Deep, authoritative V8 note, noticeably stronger than the 5.3. 2021-2024: manufacturing left metal shavings in 597,000 engines — free replacement under recall. DFM lifter collapse is the main risk: budget a Range Disabler or mechanical delete as first investment. Pre-2021 or confirmed post-recall units with documented 5,000-mile oil changes (0W-40 Dexos) are the safest buy.
