Overview

2014 Audi S8

The 2014 Audi S8 is a potent, all-wheel-drive luxury sedan that blends serious performance with a refined interior. Under the hood, a 4.0-liter V8 engine paired with an automatic transmission delivers brisk acceleration. However, potential buyers should be aware of its average reliability rating and a notable number of recalls, particularly those related to fuel delivery and turbocharger lubrication. Despite zero owner complaints logged with NHTSA, the high volume of Technical Service Bulletins (TSBs) suggests a complex vehicle that may require diligent attention to maintenance.

Critical Failure Risk

Recalls have addressed potential leaks in the high-pressure fuel lines. These issues can arise from material degradation or porosity, leading to fuel seepage.

Early detection can help you avoid a $1,000-$2,500 repair.
