For the 2012 Audi A8, engine issues make up the largest share of what owners report. Complaints describe timing chain failures triggering the check engine light, as well as engine oil leaks that can cause the engine to shut off without warning while driving. Separately, a couple of owners report losing power steering assist, describing the steering wheel becoming stiff when the power steering pump fails. One owner also notes an airbag warning light staying on after startup, with a fault code pointing to a driver side curtain airbag igniter short circuit. The complaint volume here is small, so most of these patterns rest on two or three reports each rather than a broad sample.
