2009 Audi S4 — reported problems

What the records are about, by source

Each source is kept separate: owner complaints, recalls, manufacturer communications and investigations are different kinds of record and are never added together. All model years.

• Owner complaints (1,116 records, model years 2000–2022) are most frequently classified under: electrical system, powertrain (transmission & drivetrain) and brakes.
• Manufacturer communications (15,566 records, model years 2000–2025) are most frequently classified under: equipment & accessories, electrical system and engine.

"Most frequently classified under" reports how the records are filed by the source. It is not a finding about causes, and a record can be filed under more than one system. Read the individual records
