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, Hyundai Santa Fe, Jeep Cherokee

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.

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.

This issue also affects: Volkswagen Atlas, Ford Mustang Mach-E, Jeep Compass

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.

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.

What Owners Are Using

Parts and tips from 920+ owners who fixed this issue

TipCheck your oil level monthly on the 1.5L Bronco Sport. If the oil level is ABOVE the full mark and smells like gas, change the oil immediately regardless of the oil life monitor reading. Shorten your change intervals to 5,000 miles maximum if you do mostly short trips.
NoteDo NOT rely on the oil life monitor in cold climates with short-trip driving. The monitor does not account for fuel dilution. Oil diluted with gasoline loses its lubricating properties and can cause premature engine wear. Check the dipstick - if it smells like gas, change it.

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: Acura CL, Acura ILX, Acura MDX

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.

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.

This issue also affects: Land Rover Range Rover Sport, Ford Flex, Land Rover Discovery

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.
