Buick Rainier — reported problems
CarFaultIQ holds 5,016 evidence records for the Buick Rainier (2004–2007), drawn from official sources and owner complaints.
What owners report: issue areas
Owner complaints are classified by the system they concern: 1,048 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.
- Electrical system292 (27.9%)Official recall records for this system: 6, covering model years 2006–2007.
- Fuel system186 (17.7%)
- Lights114 (10.9%)Official recall records for this system: 9, covering model years 2004–2007.
- Powertrain (transmission & drivetrain)56 (5.3%)
- Suspension50 (4.8%)
- Air bags (restraint system)44 (4.2%)
Other / uncategorized: 24 classifications (2.3%) were not assigned to a specific system by the source. They are counted but not treated as an issue area.
These are counts of records held by CarFaultIQ, not a failure rate. More records can simply mean more vehicles were sold or more owners reported. No vehicles-in-service figure exists in this data, so no reliability or risk score can be derived from it.
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 (780 records, model years 2004–2007) are most frequently classified under: electrical system, fuel system and lights.
- Manufacturer communications (4,158 records, model years 2004–2007) 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
Mileage reported when the issue occurred
- 630reports included a mileage
- 76,194average of those mileages
This is the mileage owners recorded at the time they reported, not an expected failure mileage and not a prediction for any individual vehicle. The lowest and highest figures on record are not shown: they are unverified odometer entries that include zeros and implausibly high readings, so they would not describe a real range. A median is not shown either, because the stored figures are group totals and a median cannot be recovered from them.
Evidence by model year
Records held per model year. Select a year to narrow this page to it.
- 2004 819 records for 2004
- 2005 790 records for 2005
- 2006 888 records for 2006
- 2007 913 records for 2007
Counts are not adjusted for how many vehicles were sold in each year, so a taller year is not necessarily a worse year.

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.
