Best Model Years

Years to Avoid
No specific years to avoid within the 1998-2005 generation, as common issues are widespread across all.

Top Risk Areas
The systems that tend to fail first on the 2004 Chevrolet Blazer, 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 in-tank fuel pump is a notorious failure point, often leading to no-start conditions or stalling. The 'spider' fuel injector assembly can also clog or fail, causing misfires and rough idle.
Ball joints, idler arms, pitman arms, and tie rod ends wear out frequently, leading to loose steering, clunking noises, and uneven tire wear. Power steering pumps and lines are also prone to leaks.
Issues range from faulty gauge clusters (especially speedometer), power window motors, BCM (Body Control Module) failures, and general wiring harness deterioration, leading to various intermittent problems.
