Best Model Years
For this generation of Seville (STS/SLS), 2000-2004 are largely similar in terms of reliability and Northstar issues. No specific 'best' year in terms of avoiding the core problems.
Years to Avoid
All model years equipped with the Northstar V8, including the 2002, carry inherent risks. There isn't a 'safe' year within this era regarding the main engine concern.

Top Risk Areas
The systems that tend to fail first on the 2002 Cadillac Seville, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The aluminum block's head bolt threads are prone to pulling out, leading to coolant intrusion into the oil, overheating, and complete engine failure. This is often an engine-out repair.
Failures are common in the Driver Information Center (DIC) pixels, power window regulators/motors, door lock actuators, HVAC blend door actuators, and ABS modules.
Vehicles equipped with Magnaride (active suspension) or air suspension often experience expensive failures of shocks/struts, air compressors, or sensors, leading to poor ride quality.
