1999 Buick Riviera — 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 (504 records, model years 1995–1999) are most frequently classified under: engine, brakes and steering.
• Manufacturer communications (351 records, model years 1995–1999) are most frequently classified under: powertrain (transmission & drivetrain), 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

These codes appear by explicit identifier in official records matched to this exact model and year.
