On the 2005-2010 Ford Mustang, on 2005-2010 Mustangs, the passenger seat occupant classification system (OCS) can fail or become inaccurate, illuminating the airbag warning lamp and causing the passenger airbag to be disabled. Ford issued Customer Satisfaction Program 15B24 for certain vehicles because the OCS may not properly detect an adult occupant. Owners commonly report an airbag light, 'pass airbag off' staying on with an adult seated, and failed state inspections.

This issue also affects: Ford F-150

Common Symptoms

  • Airbag warning light illuminated
  • Passenger airbag off indicator stays on with adult passenger
  • SRS fault messages
  • Failed safety inspection due to airbag light

How to Fix

Scan the restraints control module for OCS-related faults and verify passenger seat weight sensor operation with IDS or equivalent capable scan tool. Repair typically involves replacing the passenger seat cushion/OCS mat or related seat sensor components, then performing the required OCS calibration procedure. Wiring under the seat should also be inspected for connector damage or high resistance before replacing parts.

Typical repair cost:$700 - $1,800

On the 2005-2014 Ford Mustang, many 2005-2014 Mustangs were included in the Takata airbag inflator recalls. The driver airbag inflator can degrade over time, especially in hot and humid climates, and may rupture during deployment, sending metal fragments into the cabin. This is a major safety defect documented by federal recalls and owner notifications.

This issue also affects: Ford Ranger

Common Symptoms

  • no warning symptoms before failure
  • open airbag recall notice
  • SRS concern only if related components are disturbed during service

How to Fix

Check VIN status through Ford or NHTSA and have the inflator replaced immediately if open recall status exists. There is no maintenance workaround; the only proper fix is recall completion using the updated inflator module. Owners buying used Mustangs should verify recall completion before purchase.

On the 2005-2010 Ford Mustang, s197 Mustangs from the mid-2000s have a documented pattern of fuel tank cracking or leaking, often near the seam or around the evaporative emissions components. Owners report strong fuel odor in garages, visible dripping after fill-ups, and EVAP-related warning lights. Because the issue involves fuel leakage near the rear of the vehicle, it presents a fire risk and can require full tank replacement.

This issue also affects: Ford Ranger, Ford Transit Connect, Ford Escape

Common Symptoms

  • strong gasoline smell near rear of car
  • fuel dripping or wetness around tank area
  • check engine light
  • fuel smell after refueling
  • failed emissions or EVAP test

How to Fix

Inspect the tank shell, seams, filler neck area, and EVAP connections with the tank partially filled and under smoke test if needed. Replace the fuel tank if cracked; also inspect/replace damaged seals, vent valves, and straps as needed. Clear EVAP codes and verify no leaks remain after repair.

Typical repair cost:$900 - $1,800

On the 2010-2014 Ford Mustang, 2010-2014 Mustangs commonly develop paint bubbling and corrosion on the hood, especially along the front lip and around panel edges. Owners frequently report blistering under intact paint that later spreads, often attributed to aluminum panel corrosion or paint adhesion issues. While not usually a drivability problem, repair often requires refinishing or hood replacement to stop the spread and restore appearance.

Common Symptoms

  • paint bubbles on hood edge
  • blistering under paint
  • white oxidation or corrosion under finish
  • cosmetic deterioration on front hood lip

How to Fix

Inspect the hood edge, underside seams, and any bubbling areas for corrosion under the paint film. Minor cases may be sanded and refinished, but widespread bubbling usually requires stripping and repainting or replacing the hood. Proper corrosion treatment and edge sealing are important to prevent recurrence.

Typical repair cost:$500 - $1,500

On the 2005-2010 Ford Mustang 4.0L SOHC V6, the 4.0L SOHC V6 used in 2005-2010 Mustangs commonly develops coolant leaks from the composite thermostat housing and related seals. The plastic housing can warp or crack with age and heat cycling, causing external coolant seepage and sometimes overheating if the leak worsens. This is a well-known issue across Ford applications using the same 4.0L engine and is frequently documented in owner forums and repair databases.

This issue also affects: Ford Aerostar, Ford Bronco Sport, Ford Crown Victoria

Common Symptoms

  • Coolant smell from engine bay
  • Visible coolant leak near thermostat housing
  • Low coolant warning or reservoir level dropping
  • Engine running hot or overheating
  • White residue around housing seams

How to Fix

Pressure-test the cooling system and inspect the thermostat housing assembly, crossover area, and sensor ports for seepage or crusted coolant residue. Replace the thermostat housing assembly with updated parts, install new seals, and refill/bleed the cooling system properly. If overheating occurred, verify there is no secondary damage such as a stuck thermostat or compromised temperature sensor.

Typical repair cost:$250 - $700

On the 2005-2014 Ford Mustang, a common S197 complaint is front-end clunking or popping over bumps, driveways, and low-speed turns caused by worn upper strut mounts, strut bearings, or sway bar end links. The issue is widely discussed in owner forums and often appears as mileage accumulates or after lowering springs are installed. Owners describe a loose-feeling front suspension and knocking noises that can be difficult to isolate without chassis-ear or pry-bar inspection.

This issue also affects: Ford Escort

Common Symptoms

  • front clunk over bumps
  • popping noise when turning into driveways
  • knock from front suspension at low speed
  • loose or unsettled front-end feel

How to Fix

Inspect front strut mounts, bearings, sway bar end links, control arm bushings, and spring seating. Replace worn mounts and links in pairs, then perform an alignment if struts or mounts are removed. On lowered cars, verify correct end-link preload and that springs are properly indexed in the perches.

On the 2005-2010 Ford Mustang, s197 Mustangs are known to suffer from water intrusion at the cowl/windshield area that reaches the Smart Junction Box (SJB)/fuse box, leading to erratic electrical behavior. Owners report inoperative or self-activating wipers, lighting faults, battery drain, no-start conditions, and multiple unrelated electrical issues after rain or car washes. Ford published service information addressing water leak diagnosis and SJB-related corrosion concerns on these cars.

This issue also affects: Ford Transit, Ford Bronco Sport, Ford F-150

Common Symptoms

  • Wipers operate by themselves or stop working
  • Headlights or interior lights malfunction
  • Battery drain after rain
  • Intermittent no-start
  • Multiple electrical accessories acting erratically

How to Fix

Inspect the passenger-side cowl, windshield seal area, body seams, and SJB/fuse box for signs of moisture, corrosion, or water tracks. Repair involves correcting the leak path, cleaning or replacing corroded connectors, and replacing the SJB if internal damage is present. Drain paths and cowl seals should be restored so the replacement module is not damaged again.
