Bentley reliability and common MOT problems by model

Bentley shows a 7.0% combined MOT failure rate across 18,760 tests in Motintel data. Continental has one of the lower high-confidence rates at 7.7%. Arnage deserves extra checking at 10.4%.

Data sources: DVSA MOT records, official recall records, and MOT fault wording snapshots (2026-04-27, 2026-04-29, rfr_codes_2025-05-12, failure items 2023). Search-indexed model pages must clear 20,000 MOT tests and 10,000 vehicles.
