2018 Buick LaCrosse — reported problems
CarFaultIQ holds 1,005 evidence records for the 2018 Buick LaCrosse, drawn from official sources and owner complaints.
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 (4,238 records, model years 2005–2019) are most frequently classified under: electrical system, lights and air bags (restraint system).
- Safety recalls (75 records, model years 2005–2019) are most frequently classified under: electrical system, air bags (restraint system) and suspension.
- Manufacturer communications (21,964 records, model years 2005–2019) 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

Diagnostic codes found in evidence for this vehicle
These codes appear by explicit identifier in official records matched to this exact model and year.
A code appearing in a record means the code was named in that document. It is not a diagnosis of this vehicle, not a fault this vehicle has, and not an indication of urgency. Diagnosis requires reading live data from the vehicle.
