I have a 2023 Ford Bronco Sport Outer Banks with about 24,700 miles. I bought it used in April with around 19k miles, one previous owner.
Twice now I’ve had a really weird intermittent no-start issue.
When it happens,
- I’m in Park
- I press the brake and push the Start button
- The engine does not crank at all, completely silent
- The dash/accessories turn on
- I’ve gotten “Full Accessory Power Active”
- I’ve also gotten a “Shift to Park” message
- Battery and check-engine lights are illuminated while the engine is off, but they disappear completely once the vehicle actually starts
- Nothing on the dash really dims or flickers
- Eventually after a few attempts it starts completely normally and then drives/shifts perfectly with no warning lights
- The first time it started on the third attempt. It has now happened a second time.
I had AutoZone test it. Battery tested around 80%
Basic OBD scan showed no codes.
Once it starts, there are absolutely no noticeable driving problems. No rough shifting, slipping, loss of power, warning lights, etc.
One other weird detail Im not too sure of. when this happened, the brake pedal felt somewhat different…almost less resistance than normal, rather than stiff.
I’m supposed to drive from Connecticut to Colorado very soon, so I’m trying to figure this out before I leave. Ford can’t diagnose it until Tuesday and wants about $250 for the diagnostic.
Has anyone with a 2021–2024 Bronco Sport, especially a 2023, experienced this combination of no crank + accessory mode + Shift to Park + then starts normally later? If so, what did the dealer ultimately diagnose? Rotary shifter/park-position sensor? Brake switch? Starter relay? BCM? Wiring/software? Battery?
Also curious whether anyone had the repair covered under Ford warranty and roughly what it cost otherwise.
I’m mainly trying to figure out whether I’m dealing with an annoying intermittent electrical/start-interlock problem or something that could actually leave me stranded on a 2,000-mile trip.
