5/5 Overall
NHTSA 5-Star Safety Rating
For the 2015 Audi A3, the heaviest complaint volume centers on the airbag system, specifically the passenger seat occupant sensor. Owners frequently report a fault condition with the passenger-side airbag pressure sensor, which triggers warning lights and raises questions about whether the airbag will deploy correctly. The electrical system draws the next-largest share of complaints, with owners describing a range of issues including backup cameras failing to function and HVAC-related concerns, a few owners report detecting a burning smell from the vents, tracing it to the auxiliary heater connector showing signs of heat damage or melting. The seat category rounds out the top three, with most of those complaints tied back to the passenger seat sensor rather than physical seat hardware. Isolated reports mention fuel spilling from the filler neck during refueling and turbocharger failure with debris damage to the exhaust system, but neither pattern appears with enough frequency to stand alongside the airbag and electrical complaints.

Total Complaints
By System
The 2015 Audi A3 has 5 recalls, the most serious involving the fuel system: a fuel pump can fail without warning and stall the engine, and a separate issue can cause a fuel leak that raises the risk of fire.
Two airbag recalls affect occupant protection. The seat cover stitching on some vehicles may be out of specification, which can prevent the side impact airbag from deploying correctly in a crash. The passenger seat's occupant detection system can also malfunction and switch off the passenger airbag even when someone is seated, leaving that person without airbag protection in a crash. There is also a minor label recall where the certification label on certain vehicles shows an incorrect production date.
