All 2 Known Issues

On the 2000-2010 Ford Explorer, many Ford vehicles of this era, including the Explorer, were subject to recalls for the speed control deactivation switch mounted on the brake master cylinder. The switch can leak brake fluid internally, overheat, and in some cases cause an underhood fire even when the vehicle is parked and the ignition is off. This is a well-documented safety defect with multiple recalls and widespread owner awareness.

This issue also affects: Ford F-150, Ford Ranger

Common Symptoms

brake fluid leak at master cylinder switch
cruise control inoperative
burning smell from engine bay
smoke under hood
melted electrical connector
battery drain

How to Fix

Owners should verify recall completion by VIN and inspect the master cylinder area for signs of fluid seepage at the cruise control switch connector. The recall repair generally installs an updated fused jumper harness and/or replaces the switch. If there is any evidence of melting, smoke, or fluid contamination in the connector, the vehicle should not be parked indoors until repaired.

TipRun the VIN through Ford or NHTSA recall lookup before buying an older Explorer; many trucks changed hands without all cruise switch recalls being completed.
TipIf you notice brake fluid around the switch or a melted connector, disconnect the battery and avoid parking near structures until the recall repair is confirmed.
UpgradeIf the recall harness is damaged or missing after prior repairs, owners often seek the updated fused jumper harness specified in the recall campaign. (Motorcraft Cruise Control Deactivation Switch Harness)

On the 2000-2010 Ford Explorer 4.0L SOHC V6, the 4.0L SOHC Cologne V6 is notorious for timing chain guide and cassette failures, especially the rear cassette that is difficult to access with the engine installed. Plastic guide material breaks down over time, causing startup rattle, persistent chain noise, cam timing errors, and eventually severe engine damage if the chain jumps timing. This is one of the best-known Explorer engine problems of the era and is documented across owner forums, repair databases, and NHTSA complaints.

This issue also affects: Acura MDX, Buick LeSabre, Buick Park Avenue

Common Symptoms

rattle at cold start
timing chain noise from front or rear of engine
check engine light
rough running
misfire
loss of power
no-start if timing jumps

How to Fix

Diagnosis includes listening for chain rattle at cold start and idle, checking cam/crank correlation codes, and inspecting timing components if noise is present. Proper repair requires replacing the affected timing cassettes, guides, tensioners, and often chains; because rear timing components are at the back of the engine, labor is extensive and many shops remove the engine. Replacing only external tensioners may reduce noise temporarily but does not fix broken guides.

TipA brief startup tick is one thing, but repeated chain rattle lasting more than a second or two on a 4.0 SOHC should be investigated quickly before guide debris circulates through the engine.
UpgradeComplete timing service kits are commonly used when repairing these engines because replacing only one guide or tensioner often leaves other worn components behind. (Cloyes Timing Chain Kit for Ford 4.0L SOHC)
