Mercury Grand Marquis — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 7,462 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Lights1,776 (23.8%)Official recall records for this system: 2, covering model years 1995–2005.
• Electrical system634 (8.5%)Official recall records for this system: 10, covering model years 1995–2005.
• Steering630 (8.4%)Official recall records for this system: 6, covering model years 1995–2011.
• Speed control & accelerator612 (8.2%)Official recall records for this system: 2, covering model years 1995–1998.
• Engine524 (7.0%)
• Brakes448 (6.0%)

Other / uncategorized: 110 classifications (1.5%) 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 (6,022 records, model years 1995–2011) are most frequently classified under: lights, electrical system and steering.
• Transport Canada recalls (58 records, model years 1995–2011) are most frequently classified under: seat belts, electrical system and steering.
• Manufacturer communications (1,666 records, model years 1995–2011) are most frequently classified under: powertrain (transmission & drivetrain), engine and electrical system.

"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

• 3,720reports included a mileage
• 80,610average 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.

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.
