Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module (BCM). The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad.

The failure pattern owners describe
The 2008 Explorer shows a clear pattern of ignition switch failure where the key cylinder loosens inside the housing. Road bumps, keychain weight, or simple jiggling cause the ignition to register a false key-removal signal, activating the "easy entry" memory seat function and dome lights while the vehicle is still moving. Owners report the driver seat sliding all the way back—sometimes so far shorter drivers can't reach the pedals—combined with interior and exterior lights flashing on and off, especially problematic at night. The problem starts early (under 25,000 miles reported) and escalates from occasional incidents to happening almost every few minutes over bumpy road or even highway driving. Dealers often initially can't replicate the issue, but it's reproducible when the ignition is jiggled. A TSB exists; Ford has refused warranty coverage for out-of-warranty vehicles, quoting $250–$500 for key cylinder replacement.
Secondary electrical issues include alternator failures causing sudden power loss and warning light storms at highway speeds, engine stalls with complete loss of steering assist and throttle response, and one fire originating in a seat heater. A couple complaints cite thermostat housing leaks and faulty wiring harnesses, though these may be cooling-system issues reported under the electrical category.

Failure modes owners describe
Faulty Ignition Switch / Key Cylinder Loosening
The key cylinder loosens inside the ignition housing over time. Key movement from bumps, road conditions, or keychain weight causes the ignition to register false 'key removal' signals, triggering memory seat and light functions while driving.
When: Occurs as early as 22,500 miles; progresses with vehicle age and mileage, reported up to 76,000+ miles
Symptoms owners cite: Interior and exterior dome lights turn on and off while driving; Driver seat retracts to 'off position' without warning, especially when hitting bumps or dips; Seat moves back so far driver cannot reach pedals; Problem triggered by keychain movement, road bumps, braking, or jiggling the ignition; One complaint reported the key partially coming out of ignition during driving; Frequency escalates over time: initially hours apart, then every few minutes to almost continuously
Repairs/costs cited: Dealer estimates $250–$500 for ignition switch or key cylinder replacement; one owner reported $300 repair cost after ignition tumbler replacement; Ford Motor Company refused to cover costs despite acknowledging TSB (Technical Service Bulletin)
Recalls/TSBs owners mention: TSB exists acknowledging the issue as a common complaint; no recall issued; Ford refused financial assistance in multiple complaints; dealerships often unable to replicate problem initially
Alternator and Charging System Failure
Alternator fails to maintain proper charging voltage, causing repeated instrument cluster warning displays and power loss while driving. One complaint reported a control module failure (P0607 code).
When: Mileage not specified; one incident occurred within 3 months of prior alternator/battery replacement
Symptoms owners cite: Dashboard warning lights illuminate en masse ('lit up like a Christmas tree'); Check Engine light, Check Charging System light, and other warning indicators come on; Audible alarms sound from dashboard; Complete loss of power and stiffened steering at highway speed (65 mph); Loss of throttle response while driving; Engine does not labor or appear to fail, but vehicle stalls mid-drive; Vehicle can be restarted and operates normally thereafter, but problem recurs
Codes mentioned: P0607 (Control Module Failure or Corrupt)
Repairs/costs cited: One owner replaced alternator and battery at cost of approximately $700; problem recurred within 3 months; replacement covered under independent shop warranty; cleaning battery cables and achieving 14+ volts from alternator did not resolve the issue
Engine Stalling and Loss of Power
Engine stalls suddenly while driving at various speeds. Owners report loss of propulsion, steering assist, and throttle control. One complaint attributed root cause to throttle-body wiring routed near cooling hoses, causing wire degradation and cracking over time.
When: No specific mileage reported; one owner noted incident while trying to maintain highway traffic speed
Symptoms owners cite: Vehicle fails to accelerate and stalls out while driving; Steering stiffens due to loss of power assist; Complete loss of throttle response; All warning indicators illuminate simultaneously; Vehicle restarts successfully after stalling; One complaint referenced wires rooted next to cooling hoses that rot from heat and crack/snap
Repairs/costs cited: One owner reported massive coolant leak from cheap plastic thermostat housings; thermostat and housing replaced in 2014; vehicle eventually scrapped due to recurring issues
Recalls/TSBs owners mention: No recalls issued for throttle-body wiring or thermostat housing failures despite owner research showing design defect
Thermostat Housing Coolant Leak
Plastic thermostat housing fails, causing continuous coolant leakage. Owner reported this as a design defect Ford did not recall.
When: First failure at 76,194 miles; second failure (thermostat replacement) in 2014
Symptoms owners cite: Strong burning odor inside cabin while driving at 55 mph; Continuous coolant leakage onto ground; Massive coolant leak underneath hood
Repairs/costs cited: Thermostat housing replaced at independent mechanic; thermostat and housing replaced again in 2014
Seat Heater Fire
Passenger seat caught fire, likely from faulty seat heater element. Vehicle sustained massive fire damage while parked unoccupied in driveway.
When: No mileage or timing specified
Symptoms owners cite: Passenger seat ignited while vehicle parked; Massive fire damage to vehicle
Right Rear Turn Indicator Failure
Right rear turn signal indicator stopped functioning due to faulty wiring harness.
When: No specific timing provided
Symptoms owners cite: Right rear turn indicator light failed
Main Computer Module Failure
Main computer chip failed, causing vehicle to stall with all warning indicators illuminated. Vehicle could not be restarted.
When: 62,334 miles
Symptoms owners cite: Vehicle stalled during left turn; All warning indicators illuminated; Vehicle unable to restart after stalling
Repairs/costs cited: Diagnosed at independent mechanic as main computer chip failure; vehicle not repaired
4x4 Module Malfunction After Battery Service
4x4 module stopped functioning after battery was changed, suggesting improper electrical sequencing or module reset issue during service.
When: Occurred during or immediately after battery replacement
Symptoms owners cite: 4x4 module became non-functional after battery change

We have a 2008 eddie bauer Ford explorer that we purchased from the dealership in 2008. Earlier this year when we went over a bump, the electronic drivers seat moved back and the interior lights turned on. It took a moment for the lights to turn off, but the seats did not move back in to place. I mentioned it to the dealership during an oil change and they couldn't replicate the problem.…
My 2008 Ford explorer has been having issues recently where it turns over and will not start, then will start. Today while driving on the freeway at 65 MPH my check engine light came on with the service wrench and the car lost all power and the steering stiffened up and was hard to steer at all almost causing me to wreck on the freeway. I lost all power and control at the gas pedal and then the…
Tl* the contact owns a 2008 Ford explorer. While driving approximately 55 MPH, the front driver's side seat moved backward independently as the interior dome light illuminated. The vehicle was taken to the dealer for diagnostic testing. The technician stated that the key cylinder would have to be replaced. The vehicle was repaired but did not remedy the failure. The failure recurred…
