Summary Verdict

The 2004 Cadillac Escalade ESV is a capable and luxurious large SUV. Its primary powertrain, the 6.0L Vortec V8, is generally robust, though intake manifold gasket leaks and oil cooler line issues are common. The 4L60-E transmission can experience torque converter or solenoid problems. The optional Auto-Ride suspension is a notable area for potential costly repairs, with air compressor and spring leaks being the main culprits. Electrical gremlins related to the BCM and occasional alternator failures are also reported. Exterior rust can be a concern on older models, and interior components like the HVAC blower motor and seat actuators may require attention. Despite these potential issues, with proper maintenance and addressing common problems, the 2004 Escalade ESV can remain a reliable vehicle.
