About the Cadillac Escalade (2002-2006)
The GMT800 Escalade is the one that made the nameplate famous. The first Escalade was a rebadged GMC Denali; the 2002 redesign gave Cadillac its own sheet metal and a 6.0 litre V8 no rival full-size SUV could match on paper. It landed just as big American luxury trucks became a cultural fixture.
The appeal today is a lot of truck for the money. Underneath the chrome it is a Tahoe or Suburban, so parts are cheap and every shop knows the platform, while the cabin still delivers leather and a quiet ride. Pick the standard body, the long ESV, or the EXT pickup.

Known issues to check before you buy
- Autoride air suspension. The optional load-levelling rear air shocks leak, and the compressor runs itself to death. Watch the rear on startup: it should rise and stay up. A sagging rear or a Service Suspension message means the same repair.
- Instrument cluster gauges. The stepper motors behind the speedometer, tachometer and fuel gauge fail from heat cycling, so needles stick or read wrong. GM ran a special coverage program on 2003-2004 trucks, long expired. Check every gauge on the test drive.
- The 4-speed automatic. The weak link. Slipping and hard shifts commonly arrive well under 100,000 miles. Feel for flare between gears, smell the fluid, and ask when the pan and filter were done.
- Steering clunk. GM service bulletin 00-02-35-003M covers 2002-2006 Escalades for a clunk felt through the wheel; the fix is a new upper intermediate steering shaft. Check the hub bearings and idler arm too.
- Open recalls. Run the VIN. Campaign 02V224000 covers all-wheel-drive trucks where the positive battery cable can rub the steering shaft (fire risk), 04V045000 a hydro-boost relief valve that makes steering and braking heavy, 03V037000 rear door hinge welds.
