The failure pattern owners describe
Forty-three owners report electrical failures on 2006 Ford Focus models. The dominant issue is wiring harness degradation in the rear hatch area: insulation cracks, broken wires, and short circuits disable the trunk light, interior door locks, brake lights, and tail lights. The harness flexes where it transitions from body to hatchback, and several owners discovered the foam protection already worn through at dealer inspection. One owner's dealer applied electrical tape as a "fix," which wore through identically to the original insulation. A second major category involves the ignition lock cylinder: the key becomes stuck and cannot be removed. Repairs cost $300–$400 at dealerships. Some owners report the lock sticking repeatedly even after dealer replacement. The third issue is rear door locks that fail to engage electrically, leaving the vehicle unsecured; owners emphasize this as a child safety and carjacking risk. Additional electrical failures include engine compartment wiring rubbing against bare metal, causing alternators to fail and creating fire hazard conditions; a new 2006 Focus caught fire at 2,000–3,000 miles. One owner's dealership blamed a soda spill for the ignition failure and refused warranty coverage. Several owners discovered recalls posted years earlier for identical problems but not applied to their 2006 model year.

Failure modes owners describe
Rear Hatch Wiring Harness Cracking/Breaking
Wiring harness running from interior to rear hatch door develops cracked insulation and broken wires due to flexing and bending when hatchback is opened and closed. Poor design lacks strain relief at connection points. Causes intermittent shorts affecting multiple circuits.
When: Various mileages; failures reported early in ownership through higher mileage
Symptoms owners cite: Hatchback does not open electrically via button or fob; Fuse #63 blows repeatedly, disabling interior door locks; Trunk/hatch light does not illuminate; Door open indicator stays on even with all doors closed; Brake lights do not work or blow fuses; Parking lights and tail lights fail; Marker lamp operation affected; Dashboard lights malfunction; Intermittent electrical contact causing noise in trunk area
Repairs/costs cited: Ford dealer and independent mechanics replace wiring harness. Owners report costs of partial repair authorized by extended warranty, but full replacement recommended. Some owners perform DIY repairs using electrical tape over damaged sections; tape wears through like original insulation.
Recalls/TSBs owners mention: Extended warranty programs cover some repairs, though owners report dealers authorize only temporary fixes. Complaint mentions Ford knew of harness problem since 2000 models but no recall issued for 2006 models.
Engine Compartment Wiring Chafing/Burning
Wires in engine compartment rub against bare metal components or wear through protective foam covering, causing insulation damage, short circuits, and fire hazard. Lack of proper wire clips and routing creates contact with metal surfaces during normal operation over bumps or potholes.
When: Early ownership through mid-life of vehicle
Symptoms owners cite: Running lamp fuses repeatedly blow; Burning smell from engine area; Battery warning light flashes; Wires fused together from heat damage; Alternator failure; Engine continues running after key removed; Fire hazard identified by electrician
Repairs/costs cited: Independent electrician identified wires touching metal and burning back to firewall. Foam protection on wires found worn through. Alternator replacement required; electrician stated fire hazard exists. Owners report powertrain warranty does not cover electrical damage.
Early Engine Fire
New vehicle (2,000-3,000 miles) ignited under the hood shortly after normal operation and parking. Flames and burning parts fell from undercarriage. Owner noted battery warning icon appeared on earlier occasions when idling with radio on.
When: 2,000-3,000 miles (6 months after purchase)
Symptoms owners cite: Flames under car within 15-20 minutes of parking; Flames about one foot high at rear of engine on left side; Melted and charred engine compartment parts; Prior battery icon warning on dash during idle; No warning noises or odors before fire
Repairs/costs cited: Fire extinguished by owner with portable extinguisher. Vehicle examined after fire but no repair details provided in narrative.
Ignition Lock Cylinder Failure
Key becomes stuck in ignition and cannot be removed. Occurs intermittently or persistently. In some cases key will not turn ignition at all. Safety concern as gear shift cannot be properly controlled when key is stuck.
When: Various mileages, from 18,000 to 123,000 miles; some recurrence after dealer repair
Symptoms owners cite: Key will not turn in ignition lock cylinder; Key stuck and cannot be removed from ignition; Key sticks temporarily (hours to weeks) or permanently; Gear shift indicator may engage without depressing brake when key stuck; Resumes sticking after dealer repair with new part; Problem occurs more frequently on warm days
Repairs/costs cited: Dealers replace ignition switch/lock cylinder assembly. Costs reported at $300-$400. One owner had locksmith build new cylinder around existing key. Warranty coverage varies; several owners report being out of warranty or warranty denial. One owner reported soda spill blamed for failure.
Recalls/TSBs owners mention: Ford customer service provides no assistance when warranty expired. One dealer stated repair needed per manufacturer authorization.
Rear Door Lock Failure
Rear passenger side door lock does not lock via remote, manual, or key operation. Lock mechanism appears to engage (sounds locked) but does not actually secure. Safety concern for child occupants and vehicle security.
When: Mid to later ownership; sudden onset
Symptoms owners cite: Rear passenger door does not lock despite appearing to lock; Remote locking does not secure door; Manual locking ineffective; Door can be opened from outside while owner thinks car is locked; Child lock feature does not prevent unlock; All other doors lock normally
Repairs/costs cited: No repair details provided in narratives.
Engine Stalling While Driving
Engine stalls and stops running while vehicle is in motion or at idle. Occurs multiple times over short period. Dashboard warning lights illuminate during stall events.
When: Early ownership; one 2006 model stalled multiple times in first week and weekend of ownership
Symptoms owners cite: Vehicle stalls while driving at various speeds; Stalling occurs multiple times over days; All dashboard lights illuminate during stall; Engine will not restart immediately after stall; Braking electrical system suspect by owner
Repairs/costs cited: Dealer inspection at Lansing Power Motors found nothing wrong. Dealer suggested purchasing new computer for vehicle. One owner involved in T-bone accident believed caused by brake failure during stall.
Recalls/TSBs owners mention: Vehicle recalled per manufacturer notification received by owner, but specific recall details not provided in narrative.
Airbag System Wiring High Resistance
Airbag warning light illuminates and remains on. Wiring system develops high resistance, rendering safety airbag system inoperative.
When: Not specified
Symptoms owners cite: Yellow airbag warning light on dash remains on; Airbag system inoperative
Repairs/costs cited: Repaired by Ford dealer under 5-year warranty by replacement of clockspring (wiring/plastic tape) in steering wheel hub.
Recalls/TSBs owners mention: Repair covered under 5-year Ford warranty.
Alternator Repeated Failure
Alternator fails multiple times on same vehicle within short period. Possibly related to wiring harness damage causing electrical surge or inadequate charging.
When: Three failures at 12,500 miles, 61 miles later, and 20,500 miles
Symptoms owners cite: Complete electrical failure; Alternator goes bad; Vehicle loses electrical power
Repairs/costs cited: Wayne Akers Ford replaced first two alternators. Owner sought second opinion from independent mechanic for third failure.
Headlight and Electrical Flickering
Headlights and all exterior lights flicker continuously when turned on at night. Condition ongoing.
When: Not specified
Symptoms owners cite: Headlights flicker all the time when on at night; All lights flicker continuously
Repairs/costs cited: Shop inspection found everything OK, but problem persists. Owner reports being pulled over by police due to flickering lights.
