Owners of the 2007 Ford Explorer often cite a specific period in automotive history where practicality met premature complexity. This mid-cycle model year represented Ford's transition away from the aging platform, yet it introduced a new set of engineering challenges. While the SUV remained capable off-road, the underlying systems began to reveal subtle vulnerabilities that have defined its long-term ownership experience. Understanding these issues is essential for anyone considering purchasing or maintaining one of these vehicles.
Common Mechanical Failures
The 2007 model year Explorer is frequently associated with a wave of transmission failures that define its legacy. The 4R70W automatic transmission, a carryover from previous generations, proved susceptible to internal wear and fluid degradation. Owners often report harsh shifting, slipping between gears, and eventual complete failure if not meticulously maintained. Repairing or replacing this transmission is one of the most significant financial hurdles an owner can face, often costing thousands of dollars.
Alongside the transmission, the rear axle assemblies have drawn considerable criticism. The constant velocity (CV) joints, specifically the inner tripod bearings, tend to wear out prematurely. This manifests as a distinct clicking noise during sharp turns, particularly when accelerating. If ignored, the joint can completely fail, leading to a catastrophic loss of drive and potentially dangerous handling on the road.
Electrical and Electronic Quirks
As the decade progressed, Ford's reliance on electronic systems grew, and the 2007 Explorer was no exception. The dashboard and console wiring harnesses are notorious for developing faults over time. These faults can cause intermittent malfunctions, such as flickering dashboard lights, inoperative power windows, or a complete failure to start the vehicle. Diagnosing these issues requires specialized knowledge, as the problem often lies in a corroded connection rather than a faulty module.
The in-dash navigation unit and radio head unit are also common points of failure. The touchscreens were known to crack, and the internal components could fail, causing the screen to freeze or display incorrect information. Replacing these units is expensive due to the integrated design, and sourcing a direct factory replacement can be a challenge years after the model year ended.
Suspension and Steering Concerns
The independent rear suspension (IRS) system, while advanced for its time, introduced reliability concerns specific to this generation. The IRS system uses a complex linkage and a transverse fiberglass leaf spring. Over time, the mounting points and control arms can wear out, leading to a noticeable clunking sound over bumps and vague handling. Repairing the IRS is labor-intensive and costly, often requiring the differential to be dropped to access the components.
Steering column issues also plague this model year. The tilt-adjustment mechanism can develop excessive play or, in severe cases, bind entirely. This not only affects the driving position but can also prevent the ignition key from turning smoothly. Inspecting the steering column for worn bushings and metal-on-metal contact is a critical part of any pre-purchase inspection for a 2007 model.
Maintenance and Reliability Tips Owning a 2007 Ford Explorer successfully hinges on proactive and preventative maintenance. Regular fluid changes are non-negotiable; transmission fluid should be changed frequently using the correct Ford specification fluid and a proper exchange method. Ignoring this single maintenance item drastically shortens the transmission's life. Similarly, the transfer case fluid requires regular service to ensure the all-wheel-drive system operates smoothly. When inspecting a used unit, potential buyers should prioritize a pre-purchase inspection by a mechanic familiar with Ford's older SUVs. Pay close attention to the rear axle for any signs of leakage and test the steering and suspension for any unusual noises. Verifying the service history, especially concerning the timing belt (which is internally located and expensive to fix if it fails), is one of the best ways to mitigate future risk.
