[roger905]

I've had my BS almost 2 weeks, 1,000 miles and got the above warning. Have others had this issue?

Not much of a back story. Normal driving (all miles have been on paved roads) it just came on and started to run real ruff. Lost cruise control, drive modes. Since it has sat for a while those issue appear to be back (parked in the yard, I haven't driven it since I got home). It is idling very fast, running up to 3,000 rpm. Waiting to hear back from dealer. I was just curious if others have had that warning show up.

There has been a rash of corroded wiring connectors , where harnesses have had to be replaced , so hopefully thats all it is . The Dealer will also hopefully take care of it .

Whoa guy, that's a mouth full. If I had to guess I'd look at a ecu harness first considering the scope of your issues. Hoping for a quick fix.

Try unhooking the battery for 5mins?

I had that warning. I just got it back after being in the shop for two weeks to replace the rear drive unit. I don’t know if that can really tell you anything though, because it’s a pretty broad warning that could be from a wide range or issues with varying severity

So basically like an IT guy telling you to unplug it and plug it back in, makes sense.

If I had to unplug my battery that means something's wrong.
It could erase an Error code that may be needed for a proper diagnosis.
No thanks, I've got a warranty.
I'll let Ford deal with it.

This is a problem, both the ECU and an electrical junction box near it are below the depth that Ford claims the Bronco can traverse. They need move the location pronto and do the same with any units in for warranty for corrosion problems. I'm sure I'm not the only person that is wondering what is going to happen if I do a water crossing. I knew there would be first-year production issues, but that doesn't mean I don't expect more from Ford.

Last Thursday I got the Powertrain Malfunction/Reduced Power warning along with a couple of others. It ran horrible and I lost numerous functions, cruise control, drive modes and so on. I had it taken to the dealership and just got it back this afternoon. The problem was a broken vacuum plug. They replaced it and it runs like new (which it is ?)

So, I've seen similar issue somewhere else on this forum but they could not figure out what was happening.
In a manual I've come across something.
There is a safe mode if your engine gets too hot and only 2 cylinders used to drive and the others to pump air in to cool it.
Check your coolant if you have reduced power.

My wife started experiencing stalling, hesitation, and lack of power when the car hit 1100 miles. We barely got it back to the dealership without a tow. The dealership performed the diagnostics and found a faulty high pressure injection pump. The pump was replaced and the problem was fixed. the service department was great. The part was pulled from production line on an emergency basis. We were advised that at that mileage there has been numerous failures.

Meaning what?

Glad you got it fixed.

We just got the ERROR message this morning, only 3k miles on our new Bronco Sport Big Bend
