POWER TRAIN:AUTOMATIC TRANSMISSION:FLUID/LUBRICANT:VALVES/VALVE BODY
Ford Motor Company (Ford) is recalling certain 2024-2025 F-150, Bronco, 2024 Ranger, 2025 Mustang, Explorer, and Aviator vehicles. The transmission valve body may have been machined incorrectly, which can cause reverse gear failure, or unexpected forward movement in reverse or neutral gear.
EXTERIOR LIGHTING:LIGHTING CONTROL MODULE
Ford Motor Company (Ford) is recalling certain 2025 Lincoln Nautilus, Mustang Mach E, and Mustang vehicles. The LED Driver Modules may contain a burnt diode, which can cause the low-beam and high-beam headlights, daytime running lights, front position lights, and front turn signals to fail in the affected headlight. On Nautilus vehicles only, this condition may also cause the rear tail light, rear turn signal, and rear position light to fail. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
EXTERIOR LIGHTING
Ford Motor Company (Ford) is recalling certain 2024-2025 Mustang, and Mustang GTD vehicles. Water may enter the body control module and cause a loss of communication with the exterior lighting, including the license plate light, side marker, and tail lights. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:GAS RECIRCULATION VALVE (EGR VALVE)
Ford Motor Company (Ford) is recalling certain 2025 Ranger, Lincoln Nautilus, Mustang, Maverick, Explorer, Escape, Lincoln Corsair, Bronco Sport, and Bronco vehicles. The exhaust gas recirculation (EGR) valve may fail, resulting in an unexpected loss of drive power.
VISIBILITY:WINDSHIELD WIPER/WASHER:MOTOR
Ford Motor Company (Ford) is recalling certain 2024-2026 Mustang and 2025-2026 Mustang GTD vehicles. During certain cold temperature conditions, the windshield wipers may function only at their high-speed setting and the washing system may fail to function properly.

Our known issues database covers the 1965-2025 Ford Mustang with 46 documented issues documented across 73,540+ owner reports.
A component within the door latches called the pawl spring tab may break, preventing doors from latching properly or giving a false sense that the door is securely closed when it is not. This is a serious safety defect as doors could open unexpectedly during driving. Ford identif… Repairs typically run $0-$0. Severity: high.
The MT82 6-speed manual transmission is notorious for multiple issues including gear grinding (especially 1st to 2nd and into 3rd gear when cold), high RPM lockout preventing shifts, notchy/difficult shifts, premature synchronizer wear, and in severe cases complete transmission f… Repairs typically run $150-$6,000. Severity: high.
The 2.3L EcoBoost engine in 2015-2019 Mustangs is prone to head gasket failure, particularly in vehicles that experience repeated heat cycles or are driven hard. Block distortion over multiple thermal cycles creates gaps between the engine block and cylinder head that the gasket… Repairs typically run $1,500-$4,500. Severity: high.
Early 2.3L EcoBoost Mustangs can experience coolant intrusion into the combustion chamber through cracked cylinder head or head gasket failure. This can cause white smoke from exhaust, coolant loss, and potential engine damage if not addressed. Repairs typically run $1,500-$4,500. Severity: high.
Early 4.6L SOHC Mustang GT models used a composite intake manifold that is known to crack around the coolant crossover/thermostat area, causing sudden coolant loss and overheating. This was a widespread Ford modular V8 problem and appears repeatedly in owner reports and service l… Repairs typically run $600-$1,400. Severity: high.
Ford has recalled certain 2025 Mustangs because the exhaust gas recirculation (EGR) valve may fail. When it does, the car can suffer an unexpected loss of drive power. NHTSA's concern is straightforward: losing power without warning — pulling out of a junction, merging, or in tra… Severity: high.
Ford recalled approximately 6,500 US-market 2015-2017 Shelby GT350 and GT350R Mustangs (built Feb 2015-Aug 2016) because the engine oil cooler tube assembly was crimped with insufficient force, allowing a hose to separate from the tube and leak oil. A sudden loss of oil can cause… Repairs typically run $0-$0. Severity: high.
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… Repairs typically run $700-$1,800. Severity: high.
The 3.8L Essex V6 in 1994-1995 SN95 Mustangs (the V6 was introduced with the SN95 redesign in 1994) is notorious for premature head-gasket failure. The combination of aluminum heads and a non-asbestos gasket that degrades over time allows coolant to wick into the gasket edge unti… Repairs typically run $1,200-$2,600. Severity: high.
On the 5.0L Coyote Mustang, P0016 sets when the Bank 1 intake camshaft (passenger side) drifts out of sync with the crankshaft by roughly 6+ degrees. The dominant root causes are Coyote-specific: a stretched primary timing chain (the tensioner bleeds down and the chain elongates,… Repairs typically run $150-$2,500. Severity: high.
The 1996-1998 Mustang GT's 4.6L 2-valve SOHC modular V8 uses an all-composite (DuPont Zytel nylon) intake manifold with an integrated coolant crossover passage at the front near the thermostat housing. The plastic crossover fatigues and cracks with age and heat cycling, causing c… Repairs typically run $400-$950. Severity: high.
The first-gen Mustang is a unibody car built from thin stamped steel with essentially no factory rustproofing, so the structure that holds the car together rots from the inside out. The worst spots are the front and rear torque boxes (the boxed brackets that tie the frame rails i… Repairs typically run $1,500-$12,000. Severity: high.
The cowl/plenum under the windshield was never painted or sealed at the factory, so the internal 'cowl hat' baffles and the floor of the plenum rust through and the seam sealer around the hat dries out. Leaves and debris also clog the cowl drains so the plenum fills with water. T… Repairs typically run $150-$1,800. Severity: high.
Early first-gen Mustangs left the factory with 4-wheel drum brakes that fade badly with repeated or hard stops and pull when wet — dangerously undersized for the V8 cars and for modern traffic. Worse, pre-1967 cars use a single-reservoir master cylinder, so a single hydraulic lea… Repairs typically run $600-$2,500. Severity: high.
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… Repairs typically run $0-$0. Severity: high.
Fox-body 5.0L Mustangs (1990-1993) mount the Thick Film Ignition (TFI-IV) module directly on the side of the distributor, where it is continuously baked by engine heat. The heat breaks down the module's internal electronics, causing intermittent misfire and stalling once the engi… Repairs typically run $60-$350. Severity: high.
2011-2014 Mustangs equipped with electric power steering can experience sudden loss of steering assist, often accompanied by a wrench light and a 'Service AdvanceTrac' or steering assist warning. Ford issued recalls and service actions on certain vehicles for steering gear or pow… Repairs typically run $0-$2,200. Severity: high.
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 th… Repairs typically run $900-$1,800. Severity: high.
The S550 Mustang's independent rear suspension (IRS) is prone to developing clunking or knocking noises when going over bumps, accelerating from a stop, or during cornering. Common causes include loose sway bar end links, loose subframe bolts, worn or binding shock mounts, loose… Repairs typically run $50-$600. Severity: medium.
The 10R80 10-speed automatic transmission exhibits issues including harsh or jerky shifting, gear hunting (constantly searching for the right gear), hesitation during acceleration, unexpected downshifts, and transmission whining. The transmission's aluminum outer shells can devel… Repairs typically run $0-$7,000. Severity: medium.
