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.
Common Symptoms
- Loud popping noise from engine
- Sudden loss of power
- Engine misfire on one cylinder
- Spark plug ejected from engine
How to Fix
If not yet blown out: Use anti-seize compound on spark plug threads, torque to spec (11-15 ft-lbs), and change plugs every 30k miles. If blown out: Install a Helicoil or Time-Sert thread repair kit ($50-150 DIY, $150-500 at shop). Preventive repair kits are also available to reinforce threads before failure.

The Ford F-150 Lightning is under recall (NHTSA 25V131000, Ford 25S18) for a supplier manufacturing defect in the high-voltage battery cells that can cause an internal short circuit. Production process deviations at the battery cell supplier caused misaligned electrodes in some cells. An internal short circuit in the battery pack increases the risk of thermal runaway and fire. Ford is aware of five vehicle fires and one injury claim that may be related. Affected vehicles were built between March 16, 2022 and August 14, 2024. Until the recall is completed, Ford advises owners to charge only to 80% maximum.
Common Symptoms
- No symptoms may be present before failure
- Unusual heat or warmth from floor/battery area
- Burning or chemical smell from under the vehicle
- Battery warning messages on the instrument cluster
- Reduced range or unexpected battery behavior
- Charging faults or errors during charging sessions
How to Fix
Contact your Ford dealer immediately to check if your Lightning is affected by recall 25S18 (NHTSA 25V131000). Until the recall is performed, charge the vehicle to a maximum of 80% state of charge. The dealer will inspect the high-voltage battery array and replace it if necessary, free of charge. Park the vehicle outdoors (not in a garage) as a precaution until the inspection is complete. Monitor for any unusual smells, smoke, or heat from the battery area.

Parts and tips from 420+ owners who fixed this issue
- TipUntil the recall is completed, set your charge limit to 80% in the vehicle settings or FordPass app. Park outdoors, not in a garage. This is a precautionary measure — the actual incidence rate is very low (5 fires out of ~100,000+ vehicles), but battery fires are serious when they occur.
Many Ford F-150 Lightning owners report persistent issues with DC fast charging, including charge fault errors, unexpectedly slow charging speeds, and sessions that terminate prematurely. Some vehicles charge at only 40-70kW at stations rated for 150-350kW. The charging speed often drops dramatically after 2-5 minutes at a fast charger, settling well below the advertised 150kW peak rate. The battery charging control module (BCCM) can develop faults that prevent DC fast charging entirely, displaying an orange charge ring and "Vehicle Charging Fault" errors. Ford has released software updates to improve charging performance, but many owners continue to experience issues.
Common Symptoms
- Orange charge indicator ring and "Vehicle Charging Fault" message
- DC fast charging speed significantly below advertised peak rate
- Charging speed drops dramatically after 2-5 minutes on fast charger
- Charge session terminates prematurely before reaching target SOC
- Level 2 AC charging works normally but DC fast charging fails
- Error messages in FordPass app during charging sessions
How to Fix
Visit the Ford dealer for the latest BCCM and powertrain software updates — Ford has released multiple OTA and dealer-applied updates that improve charging behavior. If charging fault errors persist after software updates, the BCCM may need replacement ($500-$1,500). Try different DC fast charging networks as compatibility varies. Pre-condition the battery by driving for at least 15-20 minutes before DC fast charging in cold weather to improve charging speed. Use the FordPass app to schedule departure time, which pre-conditions the battery.

Parts and tips from 340+ owners who fixed this issue
- TipAlways make sure your Lightning has the latest software update before a road trip. Ford has released multiple updates that improve DC fast charging performance. If your truck is on older software, the charging speed will be significantly slower. The dealer can check and update for free under warranty.
- TipIn cold weather, drive for at least 20 minutes before stopping at a DC fast charger. The battery needs to be warm to accept high charging rates. Use the FordPass app departure scheduling to pre-condition the battery if starting from cold. Cold battery = slow charging on all EVs, but the Lightning is particularly sensitive.
The HVAC blend door actuators can fail, causing clicking noises from the dashboard and inability to control air temperature. Air may blow only hot or only cold regardless of settings. Multiple actuators are used and any can fail.
Common Symptoms
- Clicking from dashboard
- HVAC only blows hot
- HVAC only blows cold
- Temperature doesn't change
- Air from wrong vents
How to Fix
Replace failed blend door actuator. Actuators are located behind dashboard and require some disassembly. Consider replacing multiple actuators if one fails as others may follow. OEM parts recommended.

The Ford F-150 Lightning has a recall for the integrated park module (IPM) which may fail to lock into the park position when the driver shifts into Park. Unlike conventional vehicles with a mechanical parking pawl connected to the transmission, the Lightning uses an electronic park module. If the module software fails to properly engage the park lock, the vehicle can roll away when the driver exits, increasing the risk of a crash or injury. Ford issued recall 25C69 covering 2022-2025 model year Lightning trucks.
Common Symptoms
- Vehicle rolls or creeps after being shifted to Park
- Park system warning message on instrument cluster
- Green "P" indicator does not display after shifting to Park
- Unusual delay when shifting from Drive to Park
- Parking brake required to hold vehicle on flat surfaces
How to Fix
Contact your Ford dealer to have the integrated park module software updated under recall 25C69, free of charge. Until the recall is performed, always engage the parking brake manually after shifting to Park as a redundant safety measure. Avoid parking on steep inclines without the parking brake engaged. If the vehicle displays a park system warning or does not show a green "P" indicator when shifted to Park, do not leave the vehicle unattended.

- TipAlways engage the parking brake on the Lightning, even on flat ground. This is good practice for any electric vehicle since the park mechanism is electronic rather than mechanical. Make it a habit: shift to Park, then pull the parking brake, every time.
The two-piece driveshaft uses a center support (carrier) bearing that can wear out, causing vibration and noise. The rubber support degrades over time, especially in hot climates or with heavy towing. Ford TSB addresses this issue.
Common Symptoms
- Vibration at highway speeds (40-70 mph)
- Humming or howling noise from underneath
- Vibration worse under load
- Visible cracking in carrier bearing rubber
- Clunking when shifting into gear
How to Fix
Replace the carrier bearing assembly ($150-300 parts). Consider upgrading to a heavy-duty carrier bearing if towing frequently. The job requires dropping the driveshaft and is about 2-3 hours labor. Some owners upgrade to aftermarket carrier bearings with greaseable Zerk fittings for longer life.

The vacuum pump that provides brake assist on EcoBoost F-150s can fail, resulting in a hard brake pedal and reduced braking assist. Since turbo engines don't produce intake vacuum like naturally aspirated engines, they rely on this pump.
Common Symptoms
- Hard brake pedal
- Increased stopping distance
- Brake warning light
- Whining noise from pump area
- Reduced brake assist
How to Fix
Replace vacuum pump. This is a safety-critical repair - do not drive with failed pump. Check for diagnostic codes related to brake booster. Inspect vacuum lines for leaks as well.

Certain 2023-2024 Ford F-150 Lightning trucks were recalled because the front upper control arm ball joint nut may not have been properly tightened during assembly. If the nut loosens, the control arm can separate from the steering knuckle, causing a sudden and complete loss of steering control. This is a manufacturing assembly defect rather than a design flaw, but the consequences are severe — the affected wheel can tuck under the vehicle causing the driver to lose all directional control.
Common Symptoms
- Clunking or knocking from the front suspension over bumps
- Steering feels loose or wanders at highway speed
- Uneven front tire wear
- Visible play in the front wheel when lifted off the ground
- Sudden loss of steering control (catastrophic failure mode)
How to Fix
Contact your Ford dealer to verify if your vehicle is affected by this recall. The dealer will inspect the front upper control arm ball joint torque specification and re-torque or replace the hardware as needed, free of charge. If you hear clunking from the front end or experience wandering steering, have the vehicle towed to a dealer rather than driving it. Do not drive if you suspect a loose ball joint.
What Owners Are Using
Parts and tips from 180+ owners who fixed this issue
- TipIf you hear any new clunking from the front end of your Lightning, get it inspected immediately. A ball joint separation at highway speed is one of the most dangerous suspension failures possible. Have the dealer check the torque on the ball joint nut even if you are not part of the recall — it only takes a few minutes to verify.
The 10R80 10-speed automatic transmission can develop a shudder during light acceleration, typically between 25-50 mph. This is caused by torque converter clutch issues and affects many F-150s. Ford has released multiple TSBs and fluid updates to address this.
Common Symptoms
- Shudder during light acceleration
- Harsh or jerky shifts
- Vibration between 25-50 mph
- Clunk when shifting at low speeds
- Shudder disappears under heavy throttle
How to Fix
Perform transmission fluid flush with Motorcraft Mercon ULV and add Ford friction modifier. Adaptive learning reset via FORSCAN or dealer may help. Multiple fluid changes sometimes needed. In severe cases, torque converter replacement required under warranty extension.
