1. Audi RS 6 (2002-2011)

Reliability index rating: 1,282

The twin-turbo 4.2-litre V8 RS 6 delivered mighty performance thanks to Cosworth tuning. However, a combination of so-so reliability and eye-watering repair costs befitting its bespoke nature mean the reliability index is woeful. A Mitsubishi Lancer, remember, has a score of 6. This scores 1,282 the worst performer Warranty Direct has ever seen during its 15 years in business.
