Owners describe a troubling pattern of electrical and electronic failures across 23 separate incidents. The most severe case involved unintended reverse gear engagement that caused the vehicle to drive uncontrolled for 35-40 feet, injuring the driver and a bystander. Another critical issue is sudden loss of engine power while driving—at highway merge speeds, in traffic intersections, and during normal acceleration—often with 'Charging System Needs Service' warnings. One owner found the vehicle completely immobilized and stuck in Park without warning at 13,000 miles.
Infotainment system failures are widespread: screens go black while driving, freeze on reverse camera images, and become unresponsive. Several owners report this began immediately after routine dealership service. Bluetooth constantly disconnects, and the center display sometimes fails to boot at all, leaving owners unable to access any system messages.
A recurring and concerning defect involves extremely loud digital distortion, crackling, or boom sounds emanating from the speaker system during startup or shutdown—some owners describe it as a gunshot-like explosion that causes ear pain and ringing loud enough to raise hearing damage concerns. Dealerships cannot replicate it, find no codes, and offer no repair. Ford released a software update for the F-150 but has not applied it to the Bronco Sport.
Additional electrical problems include keyless start functioning without the physical key present, battery drain forcing 'system sleep' mode that disables remote app functions, and repeated stalling at traffic lights. Multiple owners report these issues persist or recur even after manufacturer recalls and dealership repairs.
Failure modes owners describe
Loud audio distortion/boom on startup or shutdown
Extremely loud digital feedback, crackling, or boom sound emitting from the speaker system during vehicle startup or shutdown, sometimes accompanied by a high-pitched screeching or explosion-like noise. Sound is often too loud to control with volume knob and can persist even after engine shutdown. Multiple owners report the noise is so intense it causes ear pain, ringing, and concern for hearing damage.
When: At startup or shutdown; one case at 17,000 miles; occurs randomly without predictable trigger
Symptoms owners cite: Loud crackling or digital feedback through speakers; Boom or screeching noise resembling gunshot or explosion; Sound continues after ignition off; Volume control unresponsive during event; Ear pain and ringing reported; Smell of smoke reported in one case
Repairs/costs cited: Dealerships unable to replicate the sound during service visits; no fault codes displayed; Ford has released software update for F-150 but not applied to Bronco Sport; one owner told nothing can be done since fix is for F-150 only
Recalls/TSBs owners mention: Software update available for F-150 but not yet released for 2023 Bronco Sport
Infotainment screen blackout and display malfunction
Dashboard and infotainment center screen goes completely black or fails to boot properly, leaving owner unable to access radio, climate controls, navigation, or system status messages. Screen may freeze on reverse camera image and not respond to inputs. Bluetooth connectivity issues also reported alongside screen failures.
When: Multiple instances; one case at 4,100 miles; occurs while driving and during startup
Symptoms owners cite: Center display/infotainment screen goes black; Screen fails to boot up properly; Reverse camera image freezes on screen; Radio/power button becomes unresponsive; Bluetooth disconnects all devices when vehicle is turned off; Screen resets every time vehicle is turned off; Unable to see speed or system messages
Repairs/costs cited: One owner reports issue began after routine oil change/service; one dealership service director acknowledged vehicle is 'known for its electronic issues'; issues persist after multiple service attempts
Loss of power and charging system warning
Vehicle suddenly loses engine power while driving at highway speeds or during acceleration, often with 'Charging System Needs Service' and 'Shut the Vehicle Off' warning messages displayed. One case involved loss of power in heavy traffic intersection resulting in vehicle stall and lock-in; another involved inability to accelerate on highway merge. Charging system diagnosed as not charging fully.
When: While driving at 55 MPH, 5 MPH, and heavy traffic; mileage 4,100 to 34,000 miles; one case occurred after May recall for loss of power was performed
Symptoms owners cite: Sudden loss of engine power while driving; Vehicle stalls in intersection or on roadway; Charging system not functioning (vehicle not charging as intended); Wrench light and loss of power alert in Ford app; Vehicle fails to accelerate when pedal depressed; All doors lock when power lost; Intermittent power loss in traffic
Codes mentioned: Turbo codes (reported by one owner)
Repairs/costs cited: Dealerships unable to locate cause of failure in several cases; fuel system failure suspected in one case but not confirmed after 3 weeks in shop; owner requested recall be redone but was declined; owner notes recall for loss of power was already performed in May but issue recurred
Recalls/TSBs owners mention: Recall issued for loss of power (performed May 2024 in one case); manufacturer has referred owners to NHTSA Hotline; one case transferred to NHTSA by manufacturer
Transmission shift-to-Park failure / stuck in Park
Shift-by-wire system engages Park and becomes stuck, preventing vehicle from being shifted out of Park. Vehicle becomes completely immobilized with no warning. Multiple error messages appear after failure including Park Brake Fault and Pre-Collision Assist warnings.
When: Without warning; vehicle had fewer than 13,000 miles at time of failure
Symptoms owners cite: Uncommanded shift into Park while driving; Vehicle locked in Park and immobilized; Loss of essential vehicle control functions; Park Brake Fault error message; Pre-Collision Assist Not Available error message
Repairs/costs cited: Ford Service Center (Tijuana, BC) performed warranty repairs to restore functionality; vehicle had been serviced at authorized Ford dealership in US less than one month prior
Recalls/TSBs owners mention: Warranty repair performed by Ford Service Center; manufacturer notified of incident
Vehicle stalling at stop light with Auto Stop-Start enabled
Vehicle stalls intermittently at traffic stops when automatic stop-start feature is active. In one documented case, vehicle shut off immediately after releasing brake pedal while stopped at red light.
When: At traffic stops with Auto Stop-Start activated; mileage at 34,000 miles (one case)
Symptoms owners cite: Vehicle stalls at stop light; Engine shuts off immediately after releasing brake pedal; Failure occurs on several occasions
Repairs/costs cited: Multiple local dealers unable to determine cause
Recalls/TSBs owners mention: Manufacturer notified of failure
Unintended reverse gear engagement and vehicle uncontrolled motion
Vehicle suddenly engaged reverse gear without operator input and drove in reverse uncontrolled for 35-40 feet, resulting in serious injury to driver and bystander. Event occurred while owner was opening liftgate with automatic alarm active.
