Cadillac Escalade T1XX (5th Generation)

20212026 · GMT T1XX · suv

Fifth-generation Escalade on the T1XX platform (sibling to T1XX Tahoe/Yukon/Suburban). First Escalade with independent rear multilink suspension. Engines: 6.2L L87 V8 (420 hp), 3.0L LM2/LZ0 Duramax inline-six diesel (discontinued for 2025), and the Escalade-V's 6.2L LT4 supercharged V8 (682 hp). Super Cruise hands-free driving available. ESV long-wheelbase. 2025 refresh adds 55-inch curved display.

Watch out: 3.0L LM2 Duramax CP4.2 fuel pump failure on 2020-2022 builds — pump shrapnel contaminates the entire fuel system; $10,000+ repair. NHTSA EA22-002 documents the pattern across GM 3.0L applications.

Full clubhouse — owner Garage Lineage, common problems, year-by-year notes, and product picks — is on the build list.
