Warning lights on other Bronco Sport years
No other Bronco Sport model year has enough reports of warning lights for a sheet of its own. See every Bronco Sport year.
What this problem usually is
This sheet is for the moment the whole dash lights up at once: a string of warnings for systems that seem to have nothing to do with each other. Sometimes features drop out. Sometimes it's all gone on the next start. When that many systems complain together, it makes sense to look first at what they have in common.
What got replaced
Owners who name the part that was replaced mention the battery (20 reports) and the module (3 reports).
Recalls and investigations
3 recalls on the electrical system cover the 2021 model year. A recall on the same system isn't always the same failure, so read the defect text.
The engine block heater may crack and develop a coolant leak, causing it to short circuit when the block heater is plugged in.
The 12-volt battery may experience degradation and suddenly fail.
The body and power train control modules may fail to detect a change in the 12-volt battery state of charge.

What owners wrote
“Car suddenly and dangerously braked on highway with no other vehicles around. Afterwards the tool and check engine lights came on. All advance trac systems failed. Dealership replaced the broken bolts and rear axle. In review it appears recall 21s04 should apply. Site shows 2021 broncos from Hermosillo plant apply. Rep stated building date range 7/22-11/24. How can this apply to a 2021 ford recall?”

“I was waiting to turn at a red light when the engine shut down and I lost all power including all lights and locking mechanisms. I was unable to get it off the road because it was locked in gear. It had to be towed and dropped off at the dealer. It is still there at this time.”

Should you keep driving it?
This page can't tell you that. 0 of 37 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
