What is the most common problem with the 2004 Ford Explorer?
The automatic transmission is the most commonly reported issue for the 2004 Ford Explorer. While many examples run reliably with regular maintenance, owners frequently cite transmission symptoms such as slipping, hard or delayed shifting, and, in higher-mileage vehicles, eventual failure. Other recurring concerns include electrical faults and wear-related suspension components.
Understanding the issue landscape
To give readers a clear picture, this section draws on owner feedback, service histories, and recall data. It highlights the problems most often mentioned for the 2004 Explorer and explains why they tend to appear as vehicles accumulate mileage.
Most commonly reported problems
Below are problems most frequently mentioned by owners and in maintenance records for the 2004 Explorer. The list reflects common failure modes that tend to appear as mileage accumulates.
- Automatic transmission problems: slipping, hard shifts, delayed engagement, or, in some cases, transmission failure in higher-mileage vehicles.
- Electrical and sensor faults: issues with power accessories (windows, locks), dashboard warnings, ABS/traction control sensors, and other PCM-related faults.
- Suspension and steering wear: worn ball joints, tie rods, control arm bushings, and related suspension components that can cause wandering or uneven tire wear.
- Engine cooling and related components: radiator leaks, water pump or thermostat concerns that can lead to overheating if not addressed.
- Fuel system and emissions symptoms: sporadic misfires, faulty oxygen sensors, or EVAP-related codes triggering the check engine light.
As with any older vehicle, the likelihood of these problems depends on maintenance history, mileage, and driving conditions. A solid maintenance record and timely repairs can significantly reduce risk.
Buying or owning a 2004 Explorer: practical checklist
To help assess and prevent problems, use this practical checklist. The items focus on the areas most prone to failure in the 2004 Explorer.
- Have the transmission inspected for slipping, harsh shifts, or unusual noises; review fluid condition and service history, including any prior rebuilds or major transmission work.
- Test electrical systems and components: power windows, door locks, instrument cluster gauges, warning lights, airbags, and sensors related to ABS/traction control.
- Inspect the suspension and steering components: check for play in ball joints, condition of tie rods, bushings, and struts/shocks; look for uneven tire wear and drifting during a road test.
- Check the cooling system: inspect radiator, hoses, water pump, and thermostat; monitor engine temperature during a test drive to catch overheating signs.
- Assess the fuel system and emissions: scan for codes (O2 sensor, MAF, EVAP) and test fuel delivery for smooth, even performance.
Having a qualified mechanic perform a thorough test drive and diagnostic scan is recommended before purchase or extended ownership to catch issues early and plan repairs.
Recalls and safety considerations
Check the National Highway Traffic Safety Administration (NHTSA) recall database for any open recalls on the specific vehicle VIN. Recalls can address safety-critical components and are typically repaired at no cost to the owner.
Summary
In summary, the automatic transmission stands out as the most frequently reported problem for the 2004 Ford Explorer, with electrical faults and suspension wear following closely behind. For buyers or current owners, prioritizing a transmission check, electrical diagnostics, and a suspension inspection, along with staying current on recalls, can help manage risk and maintain reliability.
