2004 Ford Thunderbird — 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.

• Engine12 (30.0%)
• Speed control & accelerator9 (22.5%)
• Powertrain (transmission & drivetrain)7 (17.5%)
• Electrical system4 (10.0%)
• Air bags (restraint system)3 (7.5%)
• Brakes2 (5.0%)

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 (1,700 records, model years 1995–2005) are most frequently classified under: brakes, engine and powertrain (transmission & drivetrain).
• Manufacturer communications (697 records, model years 1995–2005) are most frequently classified under: engine, powertrain (transmission & drivetrain) 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

• 31reports included a mileage
• 30,561average 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

6. 2004 68 records for 2004 68
7. 2005 43 records for 2005 43

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.

• P0301 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.
