Is the 1999 Ford Explorer Worth Buying?
The 1999 Ford Explorer is a compelling package on paper, but its long-term reliability is significantly hampered by several critical known issues. While capable for its time, prospective buyers must proceed with extreme caution and be prepared for substantial maintenance and potential repair costs, especially concerning its drivetrain. This is not a 'buy with confidence' vehicle for the average consumer.
Unless you are a highly experienced DIY mechanic with intimate knowledge of these vehicles, or can secure a meticulously maintained 5.0L V8 model at an exceptionally low price, the 1999 Ford Explorer poses too many significant and costly reliability risks for the average buyer. Its widespread engine and transmission…
Best Model Years
If pursuing an Explorer of this generation, the 1996-1997 models with the 5.0L V8 are marginally better due to slightly different transmission variants (4R70W) and pre-SOHC 4.0L options.
Years to Avoid
Absolutely avoid 1997-2001 models with the 4.0L SOHC V6 due to the timing chain issues. The 1999 model year falls squarely in this problematic period.
Biggest Strengths
- Rugged frame-on-body construction
- Available V8 power (5.0L)
- Good off-road capability for its class
What Tends to Fail First on the 1999 Ford Explorer
The systems that tend to fail first on the 1999 Ford Explorer, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The overhead cam design utilizes plastic timing chain guides/cassettes that are prone to premature wear and failure. This can lead to loud rattling, timing chain jumping, and catastrophic engine damage. It's a design flaw, not just wear…
This transmission is notorious for various issues including delayed shifts, slipping, harsh engagement, solenoid failures, and eventual complete failure. Valve body issues and worn internal components are common culprits, leading to expe…
Common problems include failures of power window motors/regulators, HVAC blend door actuators (resulting in no heat/AC direction control), and erratic behavior of the Generic Electronic Module (GEM) causing issues like 'door ajar' warnin…
1999 Ford Explorer Mileage Danger Zones
The mileage windows when the 1999 Ford Explorer most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Early Warning Zone
At this point, you're primarily looking for early electrical gremlins or neglected basic maintenance. Suspension components might start showing very early signs of wear, especially if driven hard.
Pre-Emptive Maintenance Zone
This mileage range typically sees the onset of more significant wear items. Be vigilant for early transmission symptoms and suspension component fatigue. The blend door actuator is also a common failure point here.
High-Risk Trigger Zone
This is where critical and costly failures often begin. The 4.0L SOHC timing chain and 5R55E transmission are prime candidates for major problems. Extensive rust can also become apparent.
Terminal Risk Zone
Beyond this mileage, virtually all major components are at high risk of failure or have already been replaced. Economic viability for major repairs becomes a serious question. Expect high maintenance.
1999 Ford Explorer Ownership Cost Outlook
What it typically costs to keep the 1999 Ford Explorer on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.
Annual Maintenance
$600-900 (for routine maintenance and minor age-related repairs)
Moderate Repairs
$1,000-2,000 annually (likely due to electrical issues, suspension, or exhaust work)
How Long Does the 1999 Ford Explorer Last?
Given the severity of potential drivetrain failures, I would strongly advise against purchasing a 1999 Ford Explorer with the 4.0L SOHC V6 if it has over 70,000 miles unless documented timing chain service has been performed. For a 5.0L V8 model, I'd still be wary of anything over 120,000 miles without extensive ser…
