6.6/10
1 walk-away risk, 3 serious faults, 4 minor faults documented for this generation, weighted by severity and repair cost. Biggest factor: 1.5l cracked fuel injectors and underhood fire risk. Score methodology.
The Bronco Sport is a useful compact SUV when bought as an Escape-based daily driver with better packaging, not as a mini full-size Bronco. The expensive traps are the 1.5L fuel-injector fire recall sequence, 12V battery degradation and module logic that can cause sudden loss of electrical power, rear brake lining compliance recalls, rear drive unit seizure on early AWD vehicles, and water/moonroof bonding issues. The safest pick is a 2023-2025 Badlands with the 2.0L EcoBoost, clean rear-drive-unit history and no warning-light record, or a 2024-2025 1.5 only after the latest injector and battery campaigns are complete. Owners should re-check Ford recall status regularly because this model has had repeat actions where an older completed remedy was not the end of the story.

Engines and trims
Which Ford Bronco Sport should you buy?
On most used cars, the engine and trim choice changes the risk more than the mileage does. Narrow this down before you start viewing cars.
1.5L EcoBoost three-cylinder
2021-2025
BUY ONLY WITH CURRENT RECALL PROOF
This is the common engine and gives good economy, but it carries the Bronco Sport's biggest fire-risk story: cracked fuel injectors and repeated Ford/NHTSA actions. A clean, updated 1.5 can be fine; a fuel-smelling one is not a normal used-car negotiation.
2.0L EcoBoost four-cylinder
2021-2025 Badlands / higher-output trims
BEST ENGINE
The 2.0 avoids the 1.5 injector recall chain and suits the AWD chassis better. It costs more to buy and fuel, but for BYBA buyers it is the Bronco Sport powertrain that removes the largest known engine-specific worry.

2025 selected builds
VIN-CHECK CYLINDER HEAD RECALL
Some 2025 Ford 1.5L/2.0L MPC engine recall material involves manufacturing defects such as cylinder-head ball-plug oil leaks. Treat 2025 as a VIN-specific check year rather than assuming a new car is automatically cleaner than a 2024.
Year notes
Year-by-year buyer advice
Use this to narrow the search before you spend time travelling to view a car.
2021
Launch year for the C2-platform Bronco Sport with 1.5L and 2.0L engines, early suspension, moonroof, rear-drive-unit and brake recalls.
Buyer: A 2021 needs the longest recall audit. The 2.0 Badlands is preferable if the AWD system is quiet.
Owner: Keep early recall receipts together; launch-year buyers will ask for proof.
2022
Fuel injector recall exposure continues for 1.5L cars; rear brake compliance recall still affects many examples.
Buyer: Check injector campaign status and rear brake work before valuing mileage.
Owner: Fuel smell or brake noise should be documented with Ford while campaigns are active.
2023
More mature production, but 1.5L injector recall coverage and 12V/module concerns remain central.
Buyer: A clean 2023 can be good, especially 2.0. Do not skip battery and module scan checks.
Owner: Replace a weak 12V battery early and keep BCM/PCM update invoices.
2024
Major 12V battery/control-module recall applies to 2021-2024 Bronco Sport; later injector recall activity also matters.
Buyer: Good target year only if battery logic and injector campaigns are closed.
Owner: Sudden no-start or loss-of-accessory power is recall-relevant, not just battery age.
2025
Carryover model with newer engine-manufacturing recall context and ongoing Ford recall churn.
Buyer: Run the VIN even on nearly new stock. Check 1.5/2.0 engine recall applicability and software status.
Owner: Keep dealer update records because 2025 resale depends on showing the car is outside affected populations or repaired.
Common problems
Faults to check before buying
What fails, what it looks like, what it costs, and the quick checks you can do at the viewing - ranked by how badly each one can hurt you.
Fault 1
1.5L cracked fuel injectors and underhood fire risk
Affects
Certain 2021-2024 Bronco Sport 1.5L vehicles; repeated Ford/NHTSA recall actions.
Symptoms
Fuel smell, smoke, hot-engine odor, fuel pressure codes, recall notices, underhood fire history.
Typical repair cost
EUR 0 under recall; EUR 700-1,800 injector/rail repair; much more after fire damage.
Codes / scan clues
P0087, P008A, P00C6, misfire or fuel pressure faults.
Root cause: A high-pressure fuel injector may crack and leak fuel in the engine bay.
Quick check
- Run VIN for 22S73, 24S16, 25S76 or successor injector actions.
- Smell the engine bay after a warm idle.
- Inspect around injectors, rail and drain tube for wetness or staining.
- Scan for pressure-drop and misfire history.
Buyer note
A fuel-smelling 1.5 is a stop sign, even if it drives normally.
Owner note
Do not wait for a second warning if fuel odor appears after recall work.
Fault 2
12V battery degradation and BCM/PCM state-of-charge logic
Affects
2021-2024 Bronco Sport and related Maverick vehicles under 2024-2025 battery/module actions.

No-start, dead battery, accessory shutdown, warning lights, vehicle loses electrical power.
Typical repair cost
EUR 0 under recall; EUR 200-900 battery/software/module diagnosis.
Codes / scan clues
Low-voltage U-codes, BCM battery monitoring faults.
Root cause: Control modules may fail to detect 12V battery state changes; some batteries can degrade and fail suddenly.
Quick check
- VIN-check 24S24 and 25S02-style battery actions.
- Load-test the 12V battery, not just voltage-check it.
- Scan BCM/PCM for low-voltage history.
- Check that software updates were completed after battery replacement.
Buyer note
A dead battery on a Bronco Sport lot can point to a known recall pattern.
Owner note
Low-voltage faults can trigger unrelated-looking warnings; fix power supply first.
Fault 3
Rear brake lining manufacturing recall
Affects
Certain 2021-2022 Bronco Sport and Escape vehicles.
Symptoms
Longer stopping distance, rear brake noise, uneven pad wear, open brake recall.
Typical repair cost
EUR 0 under recall; EUR 300-900 for rear brake service.
Codes / scan clues
Usually none; ABS codes if related faults exist.
Root cause: Rear brake linings may have been manufactured incorrectly, affecting FMVSS brake performance.
Quick check
- VIN-check rear brake recall status.
- Inspect pad thickness and rotor condition on both rear wheels.
- Perform a straight-line braking test in a safe area.
- Check service invoice for actual lining replacement, not just inspection.
Buyer note
A compact SUV with unresolved brake compliance work is not ready for handover.
Owner note
Brake recall paperwork helps resale more than aftermarket pads.
Fault 4
Rear drive unit seizure from inadequate lubricant
Affects
Certain 2021 Bronco Sport AWD and related C2-platform vehicles.
Symptoms
Rear axle howl, binding, vibration, loss of AWD, metal debris, recall notice.
Typical repair cost
EUR 0 under recall; EUR 1,500-3,500 rear drive unit repair.
Codes / scan clues
AWD module faults, rear drive unit temperature or clutch codes may appear.
Root cause: Inadequate lubricant in the rear drive unit can cause seizure of the rear drive axle.
Quick check
- Confirm AWD and run VIN recall lookup.
- Drive tight circles and listen for binding or groan.
- Inspect rear drive unit for leaks and fresh replacement marks.
- Scan AWD module for clutch or overheating history.
Buyer note
A noisy RDU turns a cheap AWD Bronco Sport into an expensive one.
Owner note
Do not keep driving with rear-end binding; the unit can fail fast once dry or damaged.
Fault 5
Moonroof glass bonding failure
Affects
Certain 2021 Bronco Sport vehicles with moonroof.
Symptoms
Wind noise, loose glass, water leak, rattle, open moonroof recall.
Typical repair cost
EUR 0 under recall; EUR 800-2,000 for glass/frame repair.
Codes / scan clues
None unless roof motor faults are present.
Root cause: Moonroof glass may not have been bonded correctly to the frame, creating detachment risk.
Quick check
- VIN-check moonroof recall.
- Inspect glass edge bond and frame for lifting.
- Open and close the roof through full travel.
- Look for water marks on headliner and overhead console.
Buyer note
A panoramic roof is not a bonus if the glass-bond recall is unresolved.
Owner note
Fix wind noise early; it can be the first hint of bond or alignment trouble.
Fault 6
1.5L oil separator housing crack and oil leak
Affects
Certain 2021-2022 Bronco Sport 1.5L vehicles.
Symptoms
Oil smell, smoke, oil on engine, low oil level, recall notice.
Typical repair cost
EUR 0 under recall; EUR 300-1,000 separator and cleanup outside coverage.
Codes / scan clues
Low oil pressure or crankcase ventilation related faults possible.
Root cause: The engine oil separator housing may crack and leak oil.
Quick check
- VIN-check 1.5L oil separator recall.
- Inspect separator housing and nearby heat shields.
- Check oil level before and after test drive.
- Look for smoke or burnt-oil smell after warm idle.
Buyer note
Oil smell on a 1.5 with injector recall history deserves a dealer check before purchase.
Owner note
Keep oil leaks away from hot exhaust parts and document the repair.
Fault 7
Early lower control arm and rear subframe fastener recalls
Affects
Selected 2021 launch-year Bronco Sport vehicles.
Symptoms
Alignment pull, clunk, uneven tire wear, suspension warning from recall lookup.
Typical repair cost
EUR 0 under recall; EUR 500-1,500 suspension repair outside support.
Codes / scan clues
Usually none; stability/ABS codes possible if alignment is severe.
Root cause: Some vehicles were built with incorrect front lower control arms or loose/missing rear subframe bolts.
Quick check
- VIN-check front control arm and rear subframe campaigns.
- Inspect subframe bolts and witness marks.
- Check tire wear across all four corners.
- Drive straight on a flat road and note steering-center position.
Buyer note
Launch-year suspension recalls are manageable only when the fix is documented.
Owner note
Get an alignment printout after any suspension campaign.
Fault 8
2025 cylinder-head ball plug oil leak recall population
Affects
Certain 2025 Bronco Sport / related Ford vehicles depending engine and build.
Symptoms
Oil leak, oil smell, smoke, low oil level, recall notice on nearly new vehicle.
Typical repair cost
EUR 0 under recall; EUR 1,000-3,000 if cylinder-head work is unsupported.
Codes / scan clues
Oil pressure or cam timing faults possible if oil loss becomes severe.
Root cause: Improperly manufactured cylinder head ball plugs can fail and leak oil.
Quick check
- Run VIN for 25V343 / 25S61-style recall applicability.
- Inspect cylinder head and block for fresh oil.
- Check oil level and smell after a hot test drive.
- Ask whether the car was held or repaired before delivery.
Buyer note
Nearly new does not mean campaign-free on late Ford small SUVs.
Owner note
A 2025 oil smell should be handled as a recall question first.
