The failure pattern owners describe
The 2006 Ford Five Hundred's electrical system exhibits multiple interconnected failure modes that owners describe as dangerous and costly. The most common issue is intermittent instrument cluster blackout—gauges bottom out or go completely blank, knocking out speedometer, tachometer, turn signals, window controls, door locks, and brake lights. These events last anywhere from seconds to weeks, then clear up temporarily. Owners report this happens during driving and at idle, and no dealer can consistently diagnose or fix it despite wiring inspections and component replacements.
Separately, headlight sockets are catching fire due to catastrophic arcing, with both driver and passenger side failures occurring within days of each other. The electronic throttle body is surging uncontrollably at idle (700–2000 RPM), causing the vehicle to lunge forward unless brakes are held. This problem recurs even after Ford's reprogramming and replacement.
Most alarming: several owners report trunk and engine compartment fires while driving or parked, with fire forensics tracing one to a chafed wiring harness to the rear lights. Others report the side mirror security light melting and burning, and a parked headlight igniting spontaneously. These fires total the vehicle quickly.
A persistent theme is chasing a wiring fault: owners replace batteries and alternators multiple times (one replaced three alternators) before the root electrical problem surfaces and fries the PCM, making repair uneconomical. Ford issued a 2006 TSB but no recall and offered limited assistance.

Failure modes owners describe
Side mirror security light fire
Security light on underside of side mirror melted and caught fire, creating acrid smoke and burned electronics. Fuse took prolonged time to blow, allowing fire to burn uncontrolled.
When: Immediately after turning vehicle off and opening trunk
Symptoms owners cite: Smoke billowing from side mirror area; Fire visible behind mirror housing; Completely melted and fused light/mirror; Strong smell of acrid, melted plastic and burned electronics
Repairs/costs cited: Light was completely melted and fused; no repair action documented
Instrument cluster electrical dropout
Instrument cluster loses power intermittently or completely, with all gauges dropping to zero or blanking out. Problem comes and goes unpredictably, lasting from seconds to weeks. Coincides with loss of turn signals, fans, radio, windows, door locks, and brake lights (though brakes still function mechanically). No wiring defects found on inspection.
When: Intermittent; occurs while driving or sitting still. Can last one week to six weeks, then clear up
Symptoms owners cite: All instrument cluster gauges bottom out or go blank; Turn signals inoperable; Fans inoperable; Radio inoperable; Electric windows inoperable; Door locks inoperable; Brake lights inoperable (backup and brake pedal lights still work); All warning lights illuminate randomly; Traction control shuts off; Air conditioning shuts off
Repairs/costs cited: Wiring inspected and cleaned with no defects found; all fuses checked; cluster panel replaced in some cases but problem recurred after 500 miles in one documented case
Recalls/TSBs owners mention: TSB 06-17-9 dated 9/4/2006 issued but no remedy provided. No recalls issued despite being reported in 2006–2007. Dealers unable or unwilling to locate problem.
Headlight socket catastrophic arcing failure
Low beam headlight socket contacts show evidence of severe electrical arcing, with burned plastic, broken socket shell, and severely burned pins. Problem affected both driver and passenger side within one week of each other. Lamps themselves remain functional except for burned pins.
When: Sockets failed within one week of each other; mounted height and weather protection rule out moisture
Symptoms owners cite: Severe arcing damage visible in socket contacts; Burned plastic in socket housing; Broken socket shell; Severely burned lamp pins; Loss of low beam headlamp function
Repairs/costs cited: Replacement sockets from Ford described as very expensive
Electronic throttle body failure and surge
Engine revs uncontrollably at idle, ranging from 700 to 2000 RPM. Causes vehicle to lunge forward uncontrollably if brakes not applied. Vehicle shuts off without warning during normal driving. Problem persists or recurs even after throttle body cleaning/reprogramming and replacement.
When: Intermittent surging at idle and stalling during highway driving. One case had recurring problem in June 2012, two years after July 2010 repair
Symptoms owners cite: Engine racing to 1500–2000 RPM at idle; Vehicle lurches forward uncontrollably; Vehicle shuts off suddenly while driving; Engine dies at speeds from 10 to 65 MPH; Backup lights come on during shutdown; Multiple engine error codes appear; Loss of power steering during stall
Repairs/costs cited: Throttle body cleaned and reprogrammed by Ford dealer (January 2013); replaced by independent mechanic (2014). Throttle body and accelerator replaced in another case along with both sensors, did not fix. One case involved PCM replacement attempt.
Recalls/TSBs owners mention: Ford offered customer satisfaction program reimbursement in one case (November 2012, reimbursement issued 2013). Ford declined assistance in another case.
Wiring harness fire in trunk
Wiring harness in rear section of vehicle ignites and burns uncontrolled. In one documented case, fire forensics determined harness to rear lights chafed against body, causing short to ground that led to fire. Vehicle becomes fully engulfed rapidly.
When: While driving or parked; one case had 64,000 miles; another incident while trunk was loaded
Symptoms owners cite: Smell of smoke while driving; Smoke visible from trunk area; Trunk fire spreading rapidly; Vehicle becomes 80–85% destroyed
Repairs/costs cited: Vehicle totaled in both documented cases
Recalls/TSBs owners mention: Ford dealership denied responsibility in one case despite servicing vehicle 25+ times
Headlight spontaneous fire
Left front headlight catches fire spontaneously while vehicle is parked and engine off. Fire destroys left front engine area and totals vehicle.
When: Parked 30 minutes in garage with engine off
Symptoms owners cite: Headlight ignites spontaneously; Fire spreads to engine area
Repairs/costs cited: Vehicle totaled by insurance
Battery charging system failure and cascade electrical damage
Chronic battery drain and charging inadequacy leads to repeated replacement attempts (2 batteries, 3 alternators) before root cause identified as wiring problem. The wiring issue ultimately fries the vehicle's computer, making total repair cost exceed vehicle value.
When: Ongoing problem; computer failure occurs after repeated battery/alternator replacements
Symptoms owners cite: Battery goes dead overnight; Low charging output; Check engine/charging system lights illuminate; Airbag light illuminates; Computer eventually fried by wiring fault
Repairs/costs cited: Replaced battery twice and alternator three times before identifying wiring problem; computer frying made repair uneconomical
Signal light melting
Signal lights melt and cease functioning. Occurs alongside cluster panel shutdowns.
When: Timing unclear; occurs with cluster panel failures
Symptoms owners cite: Signal lights melt; Signal lights stop working
Transmission shift-lock or shift failure
Vehicle unable to shift out of first gear after electrical cluster failure. In one case, transmission started slipping after fluid change at recommended interval and eventually required replacement.
When: Occurs after instrument cluster electrical shutdown in one case; transmission slipping began after service in another
Symptoms owners cite: Unable to shift out of first gear; Transmission slipping and erratic shifting
Repairs/costs cited: Transmission replacement required in one case
Oil life warning light stuck illuminated
Oil life warning message illuminates and cannot be reset, blocking visibility of odometer. Remains lit constantly despite attempted reset.
When: At 54,000 miles
Symptoms owners cite: Oil life warning constantly illuminated; Odometer visibility blocked; Warning cannot be reset
Repairs/costs cited: Oil change attempted but did not resolve issue
Air conditioning failure
Air conditioning system fails to cool. In one case, system was drained but failure persisted; mechanic determined entire A/C system needed replacement. In another case, A/C blows hot air only and does not cool while idling in hot weather.
When: One case at 94,000 miles; another related to idling in hot weather
Symptoms owners cite: A/C blows hot air; A/C does not cool while idling if outside temperature is high; Complete A/C failure
Repairs/costs cited: One case cited refrigerant control valve failure; full A/C system replacement recommended in another
Door ajar message stuck and door latch freeze
Driver door froze shut. After manual opening, driver door ajar and passenger door ajar messages remain stuck and cannot be reset, preventing access to driver controls. Diagnostic codes unrelated to door sensor malfunction.
When: After door freeze event
Symptoms owners cite: Driver door frozen shut; Persistent 'door ajar' message for both doors; Unable to reset driver controls; Messages remain even when doors are closed
Codes mentioned: P0193 (Fuel Rail Pressure Sensor)
Unexpected surging and lurching
Vehicle lurches forward violently when shifting gears or coming to a stop, even at low speeds. Also lurches when sitting still if not in park or with brakes not applied. Engine tachometer shows corresponding spike.
When: Intermittent; occurs during gear shifts, braking, and when vehicle is stationary
Symptoms owners cite: Violent forward and backward lurch during gear shifts; Violent lurch when coming to a stop; Unexpected forward movement when not in park; Engine tachometer spikes; Engine acceleration heard without driver input
Repairs/costs cited: One case: motor mounts replaced (3), new battery, safety sensor replaced; did not resolve. Another case: dealer initially unable to duplicate, then diagnosed bad alternator sending faulty signals to PCM
Alternator signaling fault to PCM
Alternator fails or sends faulty voltage/signal information to the powertrain control module, causing engine surge and unintended acceleration.
When: Intermittent; associated with engine surge during idle and driving
Symptoms owners cite: Engine surge during idle and driving; Tachometer shows unexpected RPM spikes; Unintended acceleration; Engine audibly accelerates without driver input
Repairs/costs cited: Alternator replacement in one case

During normal driving vehicle dash lights went completely out and then began to flicker while both gauges speedo and tach went left to right on and off repeatedly causing a loss of power on vehicle rendering vehicle unsafe to drive and almost causing collision.. Brought to Ford dealer replaced alternator and problem still exists after 500 dollar expense. *tr
While driving, the instrument cluster bottoms out on the speedometer, tach, and all other warnings - backup lights come on and the instrument panel lights go out.. Sometimes it will come back on by pretty quickly, other times it will be that way for a week or more. This is very dangerous and from research I've done is happening to many people. Why has there not been a recall to fix the…
