Overview

2018 Audi A5

The 2018 Audi A5 blends upscale design with a refined driving experience, making it an attractive option on the used market. Under the hood, a 2.0-liter turbocharged four-cylinder engine paired with a 7-speed automatic transmission and standard all-wheel drive delivers a balanced performance. However, potential buyers must be aware of its 'Below Average' reliability rating. This is largely due to a substantial number of recalls, particularly concerning critical airbag system components and suspension fasteners, alongside a high volume of Technical Service Bulletins (TSBs). While consumer complaints are absent in the data, the sheer volume of manufacturer-issued service actions suggests a complex maintenance history and potential for costly repairs.

Critical Failure Risk

Multiple recalls address critical airbag system issues, including faulty occupant detection sensors, inflator modules, and curtain airbag deployment problems. These can lead to airbags not deploying or deploying incorrectly in a crash.

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