TIRES:BEAD
Ford Motor Company (Ford) is recalling certain 2020 F-150 trucks equipped with 17-inch spare tires. The spare tire could have been damaged when it was installed on the rim.
EXTERIOR LIGHTING:HEADLIGHTS
Ford Motor Company (Ford) is recalling certain 2018-2020 F-150 trucks equipped with high series LED headlamps with Autolamp (On/Off) functionality. The Daytime Running Lamps (DRL) may remain activated instead of dimming to parking lamps when the Master Lighting Switch (MLS) is manually rotated from the "Autolamps" switch position to "Headlamps On." As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices and Associated Equipment."
ELECTRICAL SYSTEM:12V/24V/48V BATTERY:CABLES
Ford Motor Company (Ford) is recalling certain 2019-2020 F-150 vehicles. The fastener securing the Power Distribution Box (PDB) 12V cable and Battery Monitoring System (BMS) eyelets to the positive battery terminal may loosen and affect the vehicle's systems such as instrument panel displays and braking or steering assist. The engine could also stall.
BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
Ford Motor Company (Ford) is recalling certain 2020 Ford F-150, F-250, F-350, F-450, F-550, Explorer, Mustang, Transit, Expedition, Escape, Ranger and Edge, and Lincoln Nautilus and Corsair vehicles. Due to a poor electrical connection, the rearview camera may intermittently display a blank or distorted image. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
ELECTRICAL SYSTEM:STARTER ASSEMBLY
Ford Motor Company (Ford) is recalling certain 2020 F-150 vehicles. An incorrect attachment nut may have been used to attach the battery positive (B+) power supply cable to the starter motor, possibly affecting the electrical conductivity, resulting in excess heat and electrical arcing.

The 1997 Ford F-150 has 15 known issues documented across 1,523+ owner reports. 8 issues are rated critical: Spark Plug Thread Blowout and Internal Radiator Transmission Cooler Fails — Coolant/ATF Cross-Contamination ('Strawberry Milkshake') and 4.6L / 5.4L 2-Valve Triton Timing Chain Tensioner and Plastic Guide Rattle and 4R70W / 4R75W Automatic Transmission Failure — No Reverse, Loss of Forward Gears, and Slipping and Fuel Tank Strap Corrosion — Straps Rust and Break, Tank Can Drop (Recall 11S21 / NHTSA 11V385) and Speed Control Deactivation Switch Underhood Fire (Recall 05V388) and Carbon-Coked Idle Air Control Valve Causing Stalling at Stops and In-Tank Fuel Pump Failure — Whining, Hard Starting, Stalling Under Load, and No-Start. Prospective buyers should inspect for these issues and factor potential repair costs into their purchase decision. Regular maintenance following the manufacturer's schedule helps prevent many common problems.
Repair costs for known Ford F-150 issues range from $0 to $3,500, depending on the specific problem and whether you choose DIY or professional repair. The most critical issue, Spark Plug Thread Blowout, typically costs $150-$500 to repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
The aluminum cylinder heads on Triton V8 engines have only 4 threads for spark plugs instead of the standard 8-10. This can cause spark plugs to blow out of the head, damaging threads. Helicoil repair kits are available. Repairs typically run $150-$500. Severity: high.
F-150s with an automatic transmission route ATF through a cooler built into the radiator end tank. When the internal barrier cracks or corrodes, the two fluids cross-contaminate: pink/foamy 'strawberry milkshake' ATF appears in the coolant and coolant gets into the transmission. Repairs typically run $400-$1,500. Severity: high.
The 2-valve 4.6L and 5.4L Triton V8s (distinct from the later 3-valve cam-phaser motors) use hydraulic timing-chain tensioners and plastic chain guides that wear and fail with age. The tensioners bleed down oil pressure overnight, so the chains slap on cold start; over time the b… Repairs typically run $800-$2,500. Severity: high.
The 4R70W (and later 4R75W/4R75E) 4-speed automatic behind the 4.2L V6 and 4.6L/5.4L V8s is prone to several high-mileage failures: a broken reverse (cast) band that produces a loud POP and loss of reverse; a cracked forward-clutch drum snap-ring groove on 2005+ units causing los… Repairs typically run $1,800-$3,500. Severity: high.
Ford recalled roughly 1.1 million 1997-2003 F-150s and 2004 F-150 Heritage trucks (plus 1997-1999 F-250 under 8,500 lb) because the steel fuel-tank support straps rust and can fracture in salt-belt regions. A broken strap lets the fuel tank shift, potentially separating fuel line… Repairs typically run $0-$600. Severity: high.
Ford recalled 1994-2002 F-150s under NHTSA campaign 05V388 (September 2005) — eventually expanded to roughly 14 million vehicles across multiple campaigns — for a defective cruise control deactivation switch screwed into the brake master cylinder. The internal seal fails, brake f… Repairs typically run $0-$0. Severity: high.
On 1997-2003 F-150 pickups with the 4.6L and 5.4L Triton modular V8, P1507 is most often set by a mechanically restricted idle air bypass circuit rather than by an electrical fault in the IAC circuit, though wiring and connector faults are a documented minority cause and should n… Repairs typically run $25-$260. Severity: high.
The in-tank electric fuel pump on 1997-2004 F-150s wears out at high mileage (commonly 150k+), producing a loud whine from the tank, hard starting, and stalling that gets worse when the engine is warm or under load (climbing hills, towing). It often fails intermittently first, th… Repairs typically run $250-$700. Severity: high.
The 4.6L and 5.4L Triton V8s use one coil-on-plug per cylinder, and these coils are a very common failure item — subjected to heat, vibration, and moisture from cowl leaks — typically starting after 80k miles. A failed coil sets a cylinder-specific misfire (P0301-P0308) and often… Repairs typically run $200-$800. Severity: medium.
The Delta Pressure Feedback EGR (DPFE) sensor and the EGR throttle-body spacer passages are a chronic Check-Engine source on 1997-2004 4.2L/4.6L/5.4L trucks. The ceramic DPFE sensor drifts or cracks, and the narrow 90-degree EGR elbow passages carbon up until flow is blocked, set… Repairs typically run $50-$250. Severity: medium.
The Passive Anti-Theft System (PATS) on these trucks disables fuel/injection when the PCM cannot verify the key transponder, leaving the truck cranking but not starting with the dash theft/security light flashing rapidly. Common triggers are a worn or dead key transponder, a loos… Repairs typically run $100-$500. Severity: medium.
On electronic shift-on-the-fly 4WD F-150s, the transfer-case shift motor (and its internal encoder that reports gear position back to the control module) is a common failure. Owners see a flashing 4WD indicator or 'Check 4x4' message, the system fails to engage or disengage 4HI/4… Repairs typically run $250-$650. Severity: medium.
F-150s have a long-running problem with rainwater entering the cab from the top rear of the cab. Two sources dominate: the foam/rubber gasket behind the high-mounted third brake light dries out and cracks, and the butyl-tape seal around the fixed rear window (or the slider track)… Repairs typically run $100-$600. Severity: medium.
Many 1998-2004 F-150 4x4s with a one-piece driveshaft develop a clunk or grunt during light-to-moderate acceleration or braking and when moving off from a stop. Ford issued a TSB attributing it to the slip-yoke splines: the factory grease dries and gets tacky, so the shaft won't… Repairs typically run $60-$300. Severity: low.
The door-ajar switch built into the door latch sticks or corrodes so the truck thinks a door is open. The result is a 'door ajar' warning that stays on, interior/dome lights that won't shut off, chimes, and a parasitic battery drain that can leave the truck dead overnight. It is… Repairs typically run $40-$200. Severity: low.
