2015 Audi A4 — 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 (5,902 records, model years 1996–2024) are most frequently classified under: air bags (restraint system), engine and electrical system.
• Safety recalls (103 records, model years 1996–2022) are most frequently classified under: air bags (restraint system), electrical system and lights.
• Transport Canada recalls (108 records, model years 1996–2023) are most frequently classified under: air bags (restraint system), visibility (glass, wipers, mirrors) and electrical system.
• Manufacturer communications (18,946 records, model years 1996–2025) are most frequently classified under: electrical system, equipment & accessories 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
