2018 Buick Enclave — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 92 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Brakes21 (22.8%)
• Engine15 (16.3%)
• Powertrain (transmission & drivetrain)15 (16.3%)Official recall records for this system: 5, covering model years 2009–2020.
• Electrical system9 (9.8%)Official recall records for this system: 8, covering model years 2008–2016.
• Driver-assistance systems6 (6.5%)
• Fuel system4 (4.3%)Official recall records for this system: 3, covering model years 2014–2020.

Other / uncategorized: 8 classifications (8.7%) 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 (4,982 records, model years 2008–2026) are most frequently classified under: air bags (restraint system), steering and engine.
• Safety recalls (95 records, model years 2008–2026) are most frequently classified under: air bags (restraint system), electrical system and visibility (glass, wipers, mirrors).
• Transport Canada recalls (74 records, model years 2008–2026) are most frequently classified under: air bags (restraint system), electrical system and tires & wheels.
• Manufacturer communications (22,086 records, model years 2008–2026) 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

• 33reports included a mileage
• 38,683average 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.

Counts are not adjusted for how many vehicles were sold in each year, so a taller year is not necessarily a worse year.
