severe NHTSA 07V140000 March 26, 2007

On certain trucks equipped with a 6

Long term contact could cause wire chafe, resulting in copper wire being exposed. If this condition occurs, the battery b+ wire could short to ground increasing the risk of a fire.

Fix: Dealers will inspect the battery b+ wire location and, if necessary, reposition the wire. The recall began on april 3, 2007. Owners may contact Ford at 1-800-392-3673.

Is there a fix? Manufacturer service bulletins

The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe

The 2008 F-250 diesel cluster shows a dominant pattern: sudden, unwarned engine shutdown caused by a frayed wiring harness in the high-pressure fuel pump (HPFP) assembly. Ford acknowledged this defect in TSB 07-26-2 (August 2007), citing unprotected wiring, yet has not issued a recall. Owners report the engine dying at 50, 55, 60, and 70 mph while towing or cruising—one instance at 276,000 miles included engine fire. Braking and steering also lose power. Vehicle won't restart; towing required. Repair involves replacing the HPFP gasket and wiring harness, typically costing $2,500–$3,000+, and requires removing the cab. One owner had the identical failure recur after replacement.

Beyond the HPFP issue, owners report other electrical problems: cab rubbing wiring harnesses, causing shorts and complete electrical blackouts; charging system failure at 41,690 miles that burned the battery and starter; ignition switch stuck in crank position; alternator and battery failure cascades; instrument cluster going dark; and complete front-lighting loss while driving. One truck experienced unintended acceleration surging from 0 to 60 mph at stop lights despite replacement of the gas pedal, throttle body, and sensors—likely a software issue the dealer cannot replicate or fix. These are unverified consumer allegations, but the sheer overlap with a known manufacturer defect raises real safety concerns.

Failure modes owners describe

High-Pressure Fuel Pump (HPFP) Wiring Harness Short

Unprotected wiring in the HPFP gasket wiring harness frays or abrades, causing a short circuit that triggers sudden engine shutdown with no warning. The wiring lacks proper shielding and can rub against the cab or internal components. Ford issued TSB 07-26-2 in August 2007 acknowledging the defect.

When: Early service life through high mileage; multiple reports between 2007 and 2015; one instance at 276,000 miles with fire in engine compartment

Symptoms owners cite: Engine shuts down instantly while accelerating or cruising at highway speed; Loss of all power and acceleration; Loss of power steering and braking assist; Vehicle will not restart after shutdown; Intermittent power loss to brakes and steering before complete failure; Engine fire in engine compartment (one report at 276,000 miles)

Repairs/costs cited: Replacement of HPFP gasket and wiring harness required; cab removal necessary to access. Repair costs reported at $2,591.89 to over $3,000. Replacement wiring harness re-engineered with protective guard. One owner reported failure recurring on second replacement harness.

Recalls/TSBs owners mention: TSB 07-26-2 issued August 2007. No recall issued despite known defect. Owner reports indicate dealer acknowledgment of recurring issue.

Unintended Acceleration (Drive-by-Wire Malfunction)

Vehicle experiences sudden uncontrolled acceleration from a stop, with vehicle surging from 0 to 60 mph without driver input. Owner suspects software issue in the engine control module related to electronic throttle control. Persists despite replacement of gas pedal, throttle body, and sensors.

When: Intermittent, occurring at stop lights; vehicle has 60,000 miles but driven infrequently

Symptoms owners cite: Unintended surge forward to 60 mph when stopped at traffic light; No check engine light illuminated when failure occurs; Requires multiple key-off/on cycles to regain normal operation; Problem persists after gas pedal replacement, throttle body replacement, and sensor replacement

Repairs/costs cited: Gas pedal replaced, throttle body replaced, both sensors replaced—problem remains unresolved. Dealer cannot diagnose unless failure duplicates in shop; charges $200+ diagnostic fee.

Electrical System Shorts and Wiring Harness Damage

Cab rubs against internal wiring harness causing electrical shorts, erratic gauge and lighting failures, instrument cluster blackouts, and engine stalling. Wiring not properly protected by manufacturing design.

When: Early service life (3 weeks after new purchase in one case); recurring after initial repair

Symptoms owners cite: Electrical shorts causing multiple system failures; Engine shuts down while driving; All lights fail (high beams, driving lights, blinkers); Vehicle will not start intermittently; Instrument cluster displays zero on all gauges; Check engine light and battery light illuminate; Vehicle requires towing

Repairs/costs cited: Entire cab removal required to access and repair electrical shorts (per Ford consultant). Repair cost described as 'thousands of dollars.' One owner states they cannot afford the repair.

Charging System Failure (Alternator and Battery)

Alternator fails prematurely, burning out the battery. Starter subsequently fails. Results in complete loss of electrical power and vehicle unable to operate.

When: At 41,690 miles

Symptoms owners cite: Alternator failure; Battery burned up by failed alternator; Starter failure following battery burnout; Complete loss of electrical power; No lights or accessories operational; Vehicle unable to start

Repairs/costs cited: Alternator, battery, and starter replacement required. Vehicle out of service for approximately 2 weeks.

Accelerator Pedal and Sensor Malfunction

Loose electrical connection or faulty sensor in accelerator pedal assembly causes vehicle to decelerate without brake application. Multiple replacements of the accelerator pedal and sensor do not resolve the recurring issue.

When: Early service life; first failure at 2,310 miles

Symptoms owners cite: Vehicle decelerates from 70 mph to 40 mph within five seconds without brakes applied; Failure recurs three weeks after first repair; Failure recurs again three weeks after second repair

Repairs/costs cited: Loose connection re-secured (first repair); accelerator pedal replaced and APC sensor replaced (second repair). Problem recurred within three weeks both times.

Engine Control Module (PCM) Failure

PCM fails and requires replacement. Dealer initially accuses owner of unauthorized PCM modification, though owner denies any such work. Replacement PCM requires reprogramming, with Ford technical support needed to complete the job.

When: Early service life; difficulty starting precedes failure

Symptoms owners cite: Multiple-attempt starting required (unusual for vehicle); Check engine light illuminates; PCM error code indicates failed modification attempt

Repairs/costs cited: PCM replacement cost approximately $1,000. Dealer had difficulty reprogramming new PCM and required Ford technical support contact.

Ignition Switch Malfunction

Ignition switch does not return from START/CRANKING position to normal RUN position when released, leaving all instruments inoperative and power accessories non-functional until engine is shut off and restarted.

Symptoms owners cite: Ignition switch stuck in START/CRANKING position; Instruments remain blank and inoperative; All power accessories fail to operate; Requires shutdown and restart to restore normal function

Lighting System Failure with Intermittent Starting

Complete loss of front lighting (high beams, driving lights, blinkers) with backup sensor malfunction. Flashers work intermittently only when engine running. Vehicle exhibits intermittent starting problems and requires towing.

Symptoms owners cite: All front lights fail while driving at night; Flashers work only when vehicle running; Wrench icon and all instrument warning lights appear; Brake system warning illuminates; Backup sensor not working properly; Vehicle intermittently will not start
