Summary Verdict
The 2000 GMC Yukon XL 1500 is a capable and generally reliable full-size SUV, especially for its intended purpose of hauling and towing. The Vortec V8 engines are known for their power, though intake manifold gasket leaks and oil cooler line issues are common points of attention. The 4L60-E transmission can experience torque converter or solenoid problems, while the 4L80-E is typically more robust. Suspension components like ball joints and leaf springs may require replacement due to age and mileage. Electrical gremlins, often related to the BCM or alternator, can also arise. Exterior rust is a concern for vehicles in certain climates. Interior comfort features like the HVAC blower motor and power seat components can also fail over time. Despite these potential issues, with proper maintenance and timely repairs, the Yukon XL 1500 can remain a dependable vehicle.
