2002 Buick Century — Known Trouble Spots
The systems that tend to fail first on the 2002 Buick Century, 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 composite Lower Intake Manifold (LIM) gaskets on the 3.1L V6 engine are prone to failure, typically leaking coolant internally or externally. This can lead to coolant loss, overheating, or coolant mixing with oil, causing severe engi…
Like many older front-wheel-drive sedans, the Century experiences wear in its front suspension components, including struts, sway bar end links, and control arm bushings. This leads to noise, poor handling, and premature tire wear, parti…

2002 Buick Century Mileage Danger Zones
The mileage windows when the 2002 Buick Century most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
At this mileage, the Century is barely broken in. Focus on routine oil changes, tire rotations, and general fluid checks. Major issues are rare.
Maintenance Zone
This mileage marks a point for more significant fluid services (transmission, coolant, power steering). Keep an eye out for early signs of the LIM gasket leaking, although failure is not guaranteed yet.
Elevated Risk Zone
The probability of a LIM gasket failure significantly increases here. Suspension components will likely show wear, and brake system components may need attention. Be prepared for moderate repairs.
High Risk Zone
Beyond 120k miles, expect age-related component failures. The transmission's Pressure Control Solenoid is a common culprit, and electrical gremlins become more frequent. Thorough rust inspection is paramount.
2002 Buick Century Ownership Cost Outlook
What it typically costs to keep the 2002 Buick Century on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.
Annual Maintenance
$400-600
Moderate Repairs
$500-1,500 occasionally (e.g., LIM gasket, transmission solenoid, full suspension refresh)
How Long Does the 2002 Buick Century Last?
Focus on comprehensive service history, especially for the LIM gasket. Vehicles over 100,000 miles should be expected to need suspension components and closer scrutiny of electrical systems and rust.
