Summary
The Audi A3 Cabriolet has 7 recalls covering 2015 through 2019 model years, with the most serious being a fuel hose connector on 2018 models that can pull away from the supply line in the engine bay, creating a fuel leak that raises the risk of an engine compartment fire.
Across all model years from 2015 to 2019, the passenger seat occupant detection system can develop a faulty electrical contact that causes it to falsely flag a malfunction and shut off the front passenger airbag, leaving that seat without airbag protection in a crash. On 2018 models, the rear seat head restraint guide sleeves can be improperly welded to the seat frame, reducing head restraint stability in a collision. The 2017-2018 model years have an engine control software issue where the computer misreads flywheel movement on startup as an engine knock, adjusts the fuel mixture incorrectly, and stalls the engine. On 2015 models, the front seat covers can have incorrect stitching that prevents the seat-mounted side airbag from deploying properly in a crash. That same year, certain fuel pumps can fail outright, either preventing the engine from starting or causing it to stall while driving. A label compliance issue also affects certain 2015 trims, where the safety certification label carries an incorrect production date that can make it harder to determine whether a recall applies to a specific vehicle.
