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.

By System
The 2015 Audi A3 has 5 recalls, the most serious involving the fuel system: the fuel pump can fail without warning, stalling the engine mid-drive with no ability to restart, and a separate fuel leak on front-wheel drive models can ignite a fire.
The fuel pump defect can cause a no-start condition or a sudden stall at any speed, leaving the driver without power steering or braking assist. The fuel leak issue affects only front-wheel drive versions of this model and poses a fire risk if fuel contacts an ignition source nearby.
Two recalls cover airbag safety. The passenger seat occupancy detection system can malfunction and shut off the front passenger airbag even when someone is seated there, meaning that person would have no airbag protection in a crash. Separately, some vehicles left the factory with seat cover stitching that does not meet specification, and in a side-impact crash, this can prevent the side airbag from deploying correctly, reducing protection for both the driver and front passenger.
The fifth recall is a label issue: the certification label on certain vehicles may show an incorrect production date, which is a compliance matter rather than a mechanical safety concern.
