What stands out
Of the 4 model years of Ford Bronco Sport we track for electrical problems, this one carries the most owner complaints on file — 150.
Owners have filed 150 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
Buyer takeaway: The 2021 Bronco Sport has serious, recurring electrical and battery issues that can cause sudden total power loss while driving, stranding owners in traffic with no warning. Even after battery replacement and dealer recalls, the vehicle has continued to fail; parts for the most recent recall remain unavailable into 2025, leaving owners without remedy and bearing out-of-pocket costs for diagnostics, towing, and replacement batteries.
Owners report the 2021 Bronco Sport experiencing sudden, complete electrical shutdown while driving—engine stalls, all lights go black, and the vehicle becomes immobilized without warning. No hazard flashers work, the shifter locks, and the electronic parking brake engages, trapping the vehicle in traffic. Multiple owners have been stranded at busy intersections and highways, at serious risk of rear-end collision. Some experienced these events multiple times despite battery replacement.
The root cause appears to be chronic battery undercharging due to module faults. Ford's Recall 24V-267 addresses Powertrain Control Module and Body Control Module undercharging; Recall 24S24 replaces batteries with AGM units; and NHTSA Campaign 25V019000 covers a 12V electrical system defect. However, parts for the final remedy remain unavailable as of Q2 2025, and owners report the problem continues even after battery replacement.
Additional electrical faults include gateway module failures (affecting state emissions inspection), fuel pump and injector control module failures, infotainment system blackouts, and warning light cycling. One owner reported underhood fire with smoke and burning smell when attempting to start.
Dealerships have often blamed low battery and blamed owners, even when vehicles were still under warranty or within days of software updates. Multiple owners paid $200–$510 out of pocket for battery replacement and towing when outside warranty, while others could not obtain reimbursement. Dealers frequently cannot replicate failures or identify root causes, leaving vehicles unresolved for weeks or months.

Repairs/costs cited: Powertrain Control Module and Body Control Module firmware flashes performed at dealership. Gateway module reprogramming required but covered under Customer Satisfaction Program 22N15 for vehicles manufactured at Hermosillo plant Feb 2020–Oct 2021 (some dealers incorrectly denied coverage). One owner paid $260 for gateway module repair after dealer denied coverage. Software updates sometimes introduced new failures; one owner reported check engine light returned within 24 hours after recall software update and subsequent engine stall. Costs range from dealer diagnostics (sometimes free, sometimes $100+) to firmware flashes and part replacements.
Recalls/TSBs owners mention: Recall 24V-267 (software flash). Customer Satisfaction Program 22N15 (gateway module reprogramming, one-time coverage regardless of mileage/warranty for Hermosillo plant vehicles). Multiple owners report Ford denied coverage or delayed indefinitely; some dealers refused to acknowledge the program existed or incorrectly stated vehicle VIN did not qualify.
AC drain clogged, causing internal water leak and electrical corrosion
Air conditioning drain becomes clogged, causing water to accumulate inside vehicle cabin. Water intrusion leads to electrical short circuits, mold growth, and loss of critical systems including power steering. One unconfirmed but detailed report of systemic defect.
When: One detailed report; owner notes other 2021 Bronco Sport owners report same issue.
Symptoms owners cite: Water accumulation inside cabin; Mold and mildew smell; Loss of power steering; Multiple warning lights on dashboard; Dead battery; Vehicle no longer drivable
Repairs/costs cited: Independent service center confirmed clogged AC drain as root cause. No repair cost stated; vehicle deemed undrivable pending investigation.
Recalls/TSBs owners mention: No recall issued for AC drain issue. Ford corporate notified but has not acknowledged as recall or defect per owner report.
Fuel pump and fuel injector control failures
Fuel pump control module faults and fuel injector failures cause engine stalling and failure to start. One owner reported white smoke and burning smell under hood when attempting to start, prompting fire department response. Fuel injector recall 22N18 parts unavailable for extended period.
When: 2023–2024. One critical incident with white smoke in July 2024.
Symptoms owners cite: Vehicle will not start but keeps clicking; White smoke from under hood; Burning and fuel smell; Fuel pump control module alert; Engine stalling while driving
Repairs/costs cited: Fuel injectors replaced under Recall 22N18. One owner paid $249 tow (reimbursed only $140) plus $300+ battery replacement when vehicle would not start after parts replacement and warranty expiration. After service, owner reported continued burning smell, slow starts, and odd rubbing noise when turning. Vehicle smoked again on subsequent start attempts. Dealership later claimed burning smell was 'old fuel burning off.'
Recalls/TSBs owners mention: Recall 22N18 (fuel injector replacement). Parts unavailable for extended periods; one owner's recall was reportedly closed without parts being replaced. Owner reports dealership cleared recall without performing repair.
MyKey activation restricting vehicle operation
MyKey system becomes activated on used vehicle without current owner's knowledge or consent, restricting speed, radio volume, and requiring seat belt to use radio. Can only be deactivated with admin key and dealership labor. Owner of used vehicle (39k miles) liable for removal cost despite not activating it; previous owner had access via Ford app and set restrictions.
When: May 2024 (end of month). Owner purchased vehicle in January 2024.
Symptoms owners cite: MyKey activated message on startup; Speed restricted; Radio volume limited; Seat belt required to operate radio; Unable to deactivate without admin key
Repairs/costs cited: Dealership (Hendrick) offered to cut admin key but would not cover labor (~$400 total). Ford offered no assistance. Owner escalated to second Ford dealership which confirmed MyKey activated only via Ford app, indicating previous owner retained access and set restrictions.
Recalls/TSBs owners mention: Ford media specialist suggested owner pay for removal and keep receipt in case future recall issued (no guarantee of reimbursement). No investigation into previous owner's continued access via app. Treated as owner responsibility despite design flaw allowing prior owner to restrict vehicle remotely.
Auto start/stop feature triggering catastrophic power loss
Vehicle's engine auto start/stop feature engages at traffic lights or stops, then vehicle fails to restart, causing total power loss and immobilization. Occurs without any prior warning of low battery or electrical fault. Dealerships sometimes claim auto start/stop is cause but suggest owners simply disable it as workaround rather than address underlying issue.
When: 2023–2025, random occurrences at traffic lights or stops.
Symptoms owners cite: Auto start/stop engages as expected; Vehicle does not restart when accelerator pressed; Complete power loss follows; No warning lights or messages prior to failure; Vehicle unable to move out of traffic; Subsequent instances even after battery replacement
Repairs/costs cited: Battery replacement attempted by most dealers. One owner paid for tow ($125) and battery/labor after vehicle died at red light. Dealership blamed auto start/stop draining battery and suggested disabling feature as 'solution.' Multiple owners report no warning of low battery before total failure, making the feature inherently dangerous.
Recalls/TSBs owners mention: No formal recall for auto start/stop malfunction per narratives. Dealerships attribute to low battery but offer no system-level fix; recommend owners disable feature.
Starter failure with underhood fire hazard
Starter or starter-related electrical circuit fails catastrophically, causing underhood fire or near-fire with smoke and acrid burning smell. One owner's vehicle experienced underhood fire involving starter and battery; fire department contacted but would not respond (no visible flames). Parts damaged beyond inspection; dealership unable or unwilling to determine if related to existing recall.
When: Timing not specified in detail; vehicle owner reports 9+ months of attempts to get dealership to perform related recall (22V859).
Symptoms owners cite: Vehicle will not crank; All dash indicator lights, interior lights, and exterior lights flashing; Multiple random error messages on dashboard; Large plume of smoke from under hood; Acrid burning smell; Parking brake fault and will not disengage
Repairs/costs cited: Underhood fire confirmed by dealership; components damaged and unavailable for inspection. Dealership unable to remedy permeating smoke smell despite health concern (family member has disabling lung condition). Owner reports 9+ months of failed attempts to get dealership to perform Recall 22V859; dealer claims parts unavailable.
Recalls/TSBs owners mention: Recall 22V859 issued but parts repeatedly unavailable at dealership. Dealership refuses to state whether underhood fire is directly related to recall.
Transmission shift system failures and stuck gear selection
Electronic transmission shifter becomes inoperable or stuck, preventing driver from shifting vehicle into neutral or park. Occurs during power loss events or independently. One owner had transmission rebuilt for $13,000 due to reported short circuit in transmission wiring.
When: Various dates 2023–2024. One critical incident with $13,000 transmission repair.
Symptoms owners cite: Shifter locked in drive or park; Unable to shift to neutral despite pulling override cable; Electronic parking brake will not disengage without power; Error messages: 'Shift System Failure', 'Park Not Available. Apply Park Brake Before Exiting'; Park gear light blinking; Shifter stuck in gear during power loss events
Repairs/costs cited: One owner's dealership diagnosed short circuit in transmission wiring ($900 labor estimate initially), then discovered separate short circuit in transmission itself requiring $13,000 rebuild on a three-year-old vehicle. No parts breakdown or labor detail provided. Owner questions how transmission could fail so catastrophically on new vehicle. Vehicle had to be dragged onto flatbed tow truck because brakes locked and shifter would not engage neutral.
Recalls/TSBs owners mention: No specific recall mentioned for transmission shift failures per narratives.
Recall parts unavailability and delayed remedies
Multiple recalls issued but repair parts unavailable for months or longer, leaving owners without remedy and vehicle operating under known defect. NHTSA Campaign 25V019000 (Electrical System 12V battery defect) remains unresolved with parts availability extending into Q2 2025. Owners report VIN tool confirms parts not available but manufacturer provides no timeline or alternative remedy.
When: 2024–2025 (ongoing). Complaints span multiple recalls; 25V019000 particularly protracted.
Symptoms owners cite: Recall notification received; Parts unavailable at dealership; No timeline provided for parts availability; Vehicle remains defective and dangerous during waiting period; No alternative remedy offered
Repairs/costs cited: No repair cost to owner (warranty issue) but owners report repeated dealership visits with no resolution, time off work, towing costs, and use of loaner vehicles. Multiple owners report being referred to NHTSA hotline with no factory assistance. One owner's recall (22N15) was marked closed without parts being replaced.
Recalls/TSBs owners mention: Recalls issued: 24V-267, 24S24, 22N18, 22N15, 22V859, 25V019000. Parts for 25V019000 unavailable as of latest complaint dates; manufacturer referred owners to NHTSA and provided no reimbursement or alternative remedy.
Battery leakage causing cabin fume exposure and mold
Defective battery leaks battery acid or fumes that enter HVAC system, causing strong chemical/fume smell in cabin with associated headache and nausea. Battery installed without owner knowledge while vehicle in lender possession. Dealerships refuse to inspect HVAC system or provide safety diagnosis despite visible battery leakage.
When: Timing not specified; one detailed report.
Symptoms owners cite: Strong chemical/fume smell in cabin; Headache and nausea from fumes; Visible liquid residue and vent holes on battery; Fumes entering HVAC system
Repairs/costs cited: Owner forced to replace battery out of pocket to safely drive vehicle. Original leaking battery disposed of by dealership. No HVAC inspection or safety diagnosis performed by either dealership consulted.
Recalls/TSBs owners mention: None documented. One dealership admitted battery had 'traces of leaking fluid' but refused diagnostic inspection and attempted to close repair order without documenting safety concern.
Check engine light and warning light cycling after recall software update
After receiving and completing recall software updates, vehicle exhibits new or recurring check engine light and multiple warning light issues. Software updates sometimes introduce failures or fail to resolve underlying electrical faults.
When: 2024–2025, within days to weeks of software update.
Symptoms owners cite: Check engine light returns after software update; Service engine soon message; Multiple warning lights cycling randomly; Dashboard lights flashing on and off; Vehicle stalling immediately after software update; High RPMs and sudden loss of power while driving
Codes mentioned: Check engine light, Service engine soon
Repairs/costs cited: One owner's vehicle stalled while leaving dealership after software update recall was performed. Dealership blamed the software update itself as cause of failure. Same owner later experienced engine stalling on highway; dealership attributed it to a 'software bug' they had 'just fixed' with another recall update. Dealership also diagnosed metal debris in oil and quoted $13,000 transmission rebuild.
Recalls/TSBs owners mention: Dealers performed software updates per recall requirements but some updates appear to introduce new faults. No systemic acknowledgment of software update causing failures.

My daughter was operating the vehicle when it unexpectedly lost power and came to a stop without warning. The instrument panel began flashing, and she was unable to restart the vehicle to move it out of traffic. A jump-start was required to get the vehicle operational. It has been taken to Koons Ford Annapolis for evaluation. Vehicle mileage is aprox. 27,000
Vehicle experienced catastrophic power failure while I was driving. Without warning, the vehicle shut down completely. The engine stopped, the brakes engaged, the dash went black. There was no way to communicate with the vehicle -- no way to engage emergency flashers or even to push it to the side of the road (because the brakes were locked). There was a loud "pulse" sound coming through the…
