Cadillac Seville Sts V8 Auto (2001)
2001 Cadillac Seville Sts V8 Auto
CarHunch analysed 106 real MOT records for the 2001 Cadillac Seville Sts V8 Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2001 Cadillac Seville comes out swinging at a reliability concern: its 72.1% first-time pass rate sits 7.9 points below the UK average, and nearly 22% of these vehicles have recorded dangerous defects—a meaningful risk flag for a buyer. The low pass rate is consistent across the petrol models (71.3%), so fuel type isn't the issue here.
These Sevilles are running around 63,500 miles at median age, which is reasonable for a 23-year-old car, but they're racking up 2.5 failures and a hefty 15 advisories per test—suggesting persistent wear issues rather than catastrophic failures. Before committing to one, get a pre-purchase inspection focused on suspension, brakes, and electrical systems, since advisory counts this high typically point to accumulated component degradation in older American luxury cars.
What to check before buying a 2001 Cadillac Seville Sts V8 Auto
