The 2005 Cadillac CTS falls slightly below the UK average with a first-time MOT pass rate of 76.2% versus the national 80%, which is a modest concern—but the dangerous defect rate of 38.7% is significantly high and suggests this model has genuine structural or safety issues that buyers should take seriously. The median mileage of around 44,750 miles is genuinely low for an 18-year-old car, yet vehicles still average 3.77 failures per test, pointing to age-related wear rather than abuse.

With nearly 21 advisories per vehicle on average, these cars are prone to accumulated minor issues typical of American saloons from this era. If you're considering one, have a trusted mechanic conduct a thorough pre-purchase inspection focusing on suspension, braking, and electrical systems—the high advisory rate suggests these are the common weak spots.

We have limited data for the 2005 Cadillac Cts — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
