On the 2004-2014 Ford F-150, 2004-2014 Ford F-150 brake lines, hoses, and ABS hydraulic components corrode aggressively in salt-belt states. Steel brake lines along the frame rust through, causing sudden loss of brake fluid and reduced or no pedal feel. Front and rear hard lines and rear axle flex hoses are most commonly affected. NHTSA has received numerous complaints but no recall has been issued — replacement is owner-paid ($800-$2,000+ depending on which lines need replacing). Most failures occur after 100,000 miles in northern/coastal states; southern-state trucks rarely show the pattern. Inspect annually if you drive in salt regions.

This issue also affects: Chevrolet Silverado 1500, GMC Sierra 1500, Honda Accord

Common Symptoms

Brake pedal fades to the floor
Sudden loss of braking power
Brake fluid loss or leaks
Rear brake hose separation
ABS light on with poor braking

How to Fix

Inspect all steel brake lines, rear flex hoses, calipers, ABS hydraulic components, and the master cylinder/booster interface for leaks or corrosion. Repairs commonly include replacing rusted lines with pre-bent or custom nickel-copper lines, new rear hoses, and sometimes a master cylinder and booster; typical cost is about $300-$1,500 depending on how much of the system is affected. Bleed the full system and verify ABS operation after repair.

On the 2004-2009 Ford F-150, 2004-2009 Ford F-150 (11th-generation) suffers from Fuel Pump Driver Module (FPDM) corrosion. The aluminum-housed module mounts directly to a steel frame crossmember above the spare tire — the dissimilar-metal contact creates galvanic corrosion, accelerated by road salt and moisture. The aluminum case cracks, water shorts the internal circuit board, and the module stops driving the fuel pump. Symptoms: crank-no-start (most common), stalling after hitting a bump or stopping at lights, intermittent loss of power. Ford issued a recall for 2005-2006 F-150 FPDMs specifically; 2004 and 2007-2009 are not recall-covered but suffer the same defect. Owners typically pay $150-$400 for module replacement plus relocation hardware that mounts the module away from the steel frame.

This issue also affects: Alfa Romeo Giulia, Alfa Romeo Stelvio, Jeep Grand Wagoneer

Common Symptoms

Crank but no start
Sudden stall while driving
Loss of power
Fuel pressure-related warning or code
Intermittent starting problems

How to Fix

Inspect the fuel pump driver module and its mounting bracket for corrosion, cracking, or water intrusion, especially on rust-belt trucks. Repair usually involves replacing the FPDM and often the corroded mounting hardware or bracket, then confirming fuel pressure and wiring integrity; typical cost is about $150-$450. If the truck still will not start, test the fuel pump and rail pressure sensor circuit next.
