2007 Mercury Mariner — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 40 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Powertrain (transmission & drivetrain)11 (27.5%)Official recall records for this system: 1, covering model years 2005–2008.
• Engine9 (22.5%)
• Electrical system7 (17.5%)
• Speed control & accelerator4 (10.0%)
• Air bags (restraint system)2 (5.0%)
• Suspension2 (5.0%)Official recall records for this system: 1, covering model years 2005–2011.

Other / uncategorized: 1 classifications (2.5%) 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 (2,592 records, model years 2005–2011) are most frequently classified under: steering, powertrain (transmission & drivetrain) and engine.
• Manufacturer communications (297 records, model years 2005–2011) are most frequently classified under: powertrain (transmission & drivetrain), engine and brakes.

"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

• 30reports included a mileage
• 80,959average 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.

Diagnostic codes found in evidence for this vehicle

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

• P0451 in 1 record

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.
