On the 2025 Ford Bronco Sport, this recall applies to 2025 Bronco Sport vehicles that were built with a 1.5L or 2.0L MPC engine and an engine block heater. Ford reports that the block heater may overheat when the Bronco Sport is parked with the heater plugged in, and NHTSA's stated consequence is an increased risk of fire. Only the 2025 model year is listed for the Bronco Sport in this campaign. Since the hazard exists only while the heater is energized, it presents itself when the vehicle is parked and connected to power - typically overnight in cold weather. The 6,781 units NHTSA lists is the size of the whole campaign across every model included, not a Bronco Sport-specific count.

Common Symptoms

  • Block heater overheating when left plugged in with the vehicle parked

How to Fix

Ford dealers will perform the fix at no cost under recall 25S52: replace the engine block heater element and inspect the block heater electrical cord, replacing that cord if required. Owners who would rather not keep a block heater at all can choose Ford's alternative remedy - the element is replaced with a threaded blanking plug and the electrical cord is removed. Owner letters were mailed June 9, 2026. Verify your specific Bronco Sport by entering its VIN at nhtsa.gov/recalls, or contact Ford customer service at 1-866-436-7332 (Ford recall 25S52).

On the 2021-2026 Ford Bronco Sport, ford issued a 'Do Not Drive' safety recall for about 4,653 vehicles (roughly 2,296 of them 2021-2026 Bronco Sports) because the front lower control arm ball stud may not have been fully inserted into the front wheel knuckle (pinch bolt secured before full engagement) at the Hermosillo assembly plant or during a prior repair. Partial engagement can let the lower control arm ball joint separate from the knuckle, causing sudden loss of vehicle control.

Common Symptoms

  • Clunking or knocking from the front suspension
  • Loose or wandering steering feel
  • Abnormal tire wear or wheel alignment changes
  • Sudden loss of steering control / wheel detachment in severe cases

How to Fix

Covered under the Ford/NHTSA front-suspension ball joint recall (reported to NHTSA in late May 2026). Dealers inspect the front lower control arm ball joint on both sides to confirm it is fully seated in the wheel knuckle and repair as needed at no cost. Affected owners should not drive the vehicle until inspected.

On the 2025 Ford Bronco Sport, on 2025 Bronco Sport models with the 2.0L EcoBoost engine, the exhaust gas recirculation (EGR) valve can fail, leading to weak acceleration, engine vibration, a no-start condition, or an unexpected loss of motive power (typically at low speeds around 15 mph or below). Ford recalled roughly 12,860 Bronco Sports built 11/15/24-5/7/25 as part of a ~48,000-vehicle multi-line EcoBoost campaign and advised affected owners not to drive until repaired.

This issue also affects: Ford E-Series, Ford Escape, Ford Explorer

Common Symptoms

  • Weak or sluggish acceleration
  • Engine vibration or rough running
  • No-start condition
  • Sudden loss of drive power at low speed
  • Check engine / powertrain warning light

How to Fix

Covered under Ford recall 26S10 / NHTSA 26V122. Interim owner letters were mailed March 20, 2026; the final remedy is still under development (anticipated September 2026), at which point Ford will repair/replace the EGR valve free of charge at a dealer. Owners should check VIN status on NHTSA.gov and follow do-not-drive guidance until the fix is available.

On the 2021-2025 Ford Bronco Sport, bronco Sports with the panoramic sunroof experience water leaks into the cabin due to clogged drain tubes. Leaves, pollen, and debris collect in the sunroof tray and block the four drain tubes that run through the pillars to exit points near the wheel wells. When blocked, water overflows into the headliner and can drip onto passengers, electronics, and floor areas. The front drains clog more frequently than the rear ones.

This issue also affects: Ford Escape

Common Symptoms

  • Water dripping from headliner or dome light
  • Wet headliner fabric
  • Water pooling in footwells after rain
  • Musty smell from AC vents
  • Water stains on A-pillar trim

How to Fix

Clear the drain tubes using compressed air blown into each of the four drain openings in the sunroof tray. Follow up by flushing with water to confirm flow. The drains exit near the front and rear wheel wells — verify water flows out at each exit point. For prevention, open the sunroof periodically and wipe debris from the tray, especially in fall. Install mesh drain tube filters ($10-15) to prevent future clogs.

Typical repair cost:$0 - $500

On the 2021-2025 Ford Bronco Sport, bronco Sport windshields develop stress cracks without any apparent rock chip or impact. Cracks typically start from the edges or corners of the windshield and propagate across. The issue is attributed to body flex in the unibody structure, windshield mounting stress, and the steep windshield angle. Some owners have had multiple windshield replacements. Temperature changes (hot sun to cold AC) can trigger crack propagation.

Common Symptoms

  • Crack appearing from windshield edge with no impact
  • Crack propagating across windshield
  • Multiple windshield replacements needed
  • Crack appears after temperature change
  • Small crack grows rapidly overnight

How to Fix

Replace the windshield. OEM windshield with ADAS recalibration (for Lane Keep Assist camera) costs $500-900 at a dealer or $300-600 through a mobile glass company plus $100-200 for camera recalibration. File a complaint with NHTSA if no impact caused the crack. Some owners have gotten Ford to cover replacement as goodwill, especially if the vehicle is under the bumper-to-bumper warranty.

On the 2021-2025 Ford Bronco Sport 1.5L EcoBoost, 2021-2025 Ford Bronco Sport with the 1.5L EcoBoost 3-cylinder engine has three overlapping documented issues: (1) Oil separator housing cracking — NHTSA recall 22S21 covers 345,451 vehicles (2020-2022 Escape + 2021-2022 Bronco Sport) for cracked oil separator housings causing oil leaks and fire risk; dealers inspect and replace under warranty. (2) Fuel injector cracking — separate recall covers 2020-2023 Escape and Bronco Sport for cracked injectors leaking fuel near hot exhaust components. (3) Oil dilution from short-trip driving — unburned fuel washes past the rings into the crankcase, causing oil level to RISE above the full mark with gasoline smell on dipstick. Ford handled the oil dilution issue via Customer Satisfaction Program 21N12, which offers a one-time 10-year engine replacement covenant capped by age/mileage (many second-owner vehicles fall outside). Owners experiencing rising oil level or fuel smell should document via dealer service writes and request CSP 21N12 evaluation.

This issue also affects: Ford Aerostar, Ford Bronco, Ford Edge

Common Symptoms

  • Oil level rises above the full mark on dipstick
  • Oil smells strongly of gasoline
  • Oil appears thin and watery on dipstick
  • Reduced oil pressure (oil pressure warning in severe cases)
  • Increased fuel consumption
  • Check engine light in severe cases
  • Rough idle during cold starts

How to Fix

No permanent fix available from Ford. Mitigation: change oil every 3,000-5,000 miles instead of the factory-recommended 7,500-10,000 mile interval. Use full synthetic 5W-30 meeting Ford spec WSS-M2C961-A1. Monitor oil level monthly - if rising above the full mark with fuel odor, change oil immediately. For owners who primarily make short trips in cold weather, consider an engine block heater to reduce cold-start enrichment. This issue is inherent to the 3-cylinder direct injection design and is more pronounced in cold climates.

Typical repair cost:$50 - $300

On the 2021-2025 Ford Bronco Sport, the Bronco Sport Badlands and other AWD models with the twin-clutch rear drive unit can overheat during sustained off-road use, towing, or spirited driving. When the rear differential fluid overheats, the system disengages the rear axle to protect the clutch pack, leaving the vehicle in front-wheel-drive only. A "Rear Axle Disconnected" message appears on the dash. The issue is exacerbated in hot weather, steep inclines, and deep sand or mud driving.

Common Symptoms

  • Rear Axle Disconnected message on dash
  • Loss of AWD traction
  • Burning smell from rear of vehicle
  • Reduced power or limp mode
  • AWD warning light illuminated

How to Fix

Allow the system to cool for 15-20 minutes before resuming. For frequent off-road use, install an aftermarket rear differential cooler ($200-400). Change the RDU fluid every 20,000-30,000 miles with the correct Ford-specified fluid instead of waiting for the factory interval. If overheating occurs on normal road driving, have the dealer inspect the RDU fluid level and condition — low fluid from a seal leak accelerates overheating.

Typical repair cost:$0 - $1,500

On the 2021-2025 Ford Bronco Sport, the 8-speed automatic transmission in the Bronco Sport exhibits a noticeable delay when pulling away from a stop, particularly when the vehicle has been idling for a few seconds. The driver presses the accelerator and the engine revs but the vehicle does not move for 1-2 seconds before the transmission engages. This is most pronounced in cold weather and during the first few stops after startup. The issue creates a safety concern at intersections and when merging.

This issue also affects: Ford Contour, Ford Crown Victoria, Ford Edge

Common Symptoms

  • 1-2 second delay before vehicle moves after pressing gas
  • Engine revs but vehicle does not accelerate
  • Hesitation worse in cold weather
  • Clunk when transmission finally engages
  • Issue worse after sitting at a red light

How to Fix

Have the dealer perform the latest TCM (Transmission Control Module) calibration update — Ford has released multiple software revisions improving engagement timing. If the issue persists after the update, a transmission fluid change with Mercon ULV may help. Some owners report that switching to Sport mode eliminates the hesitation. Persistent engagement delays beyond 2 seconds should be diagnosed for possible valve body issues under powertrain warranty.
