Overview

2018 Audi S5

The 2018 Audi S5 blends performance with premium comfort, powered by a 3.0-liter V6 engine and all-wheel drive. For used car shoppers, the S5 offers a compelling driving experience, but its average reliability rating and notable recall history, particularly concerning the passenger occupant detection system (PODS) and airbags, demand thorough pre-purchase scrutiny. With 4 recalls and 232 Technical Service Bulletins (TSBs), potential buyers should prioritize verifying recall completion and inspecting systems related to the PODS.

Critical Failure Risk

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