2022 BS BL engine revving up over 4k rpm while driving

[Gadget]

I have only 1150 miles on my Bronco Sport Badlands.
Last week I parked in the garage & the vehicle auto stopped as it typically does. As I twisted the dial out of Drive to shift into park, the car restarted and the transmission made a horrible "CLUNK" noise. Now it seems to me the tyranny is making a buzzing noise in low gears as I drive under 30mph.
Today as I was coming home, I was in ECO mode, going about 25 to 30mph on a residential street. Suddenly the engine revs up to over 4k rpm really quickly. All I could think to do was throw it in Neutral before realizing it wasn't necessary as it wasn't making the car move faster. It's like the tranny was disengaged as the car revved up. My foot was completely off the gas and my floormat was safely in place. My wife and I were surprised and were like "what the heck?"
As the car was in Neutral @ 4k rpm, after about 5 seconds the engine returned to normal rpm. I then switch the drive mode back no Normal thinking it might be ECO related.
I'm going to call Ford in the morning.
Anyone experience sudden engine speed increase?

Nope but haven’t used sport mode since the first and last time I used it. My dash turned into a Christmas tree and left me stranded. Hope you get yours figured out. Also fwiw, I have three friends that we wheel with who bought big broncos. Only one still has theirs. They had tons of issues and traded for a gladiator Rubi and a JL Rubicon. They’re much happier. I’d rather have my sport badlands than a big bronco.

so you were driving engine revved to 4k and yet vehicle didn't move faster? that means your transmission isnt linked to your engine, that isnt supposed to happen when you are in gear. Why i don't know, but id definitly call dealer as that sort of decoupling isnt supposed to happen unless you are out of gear.

Hey there! I can look into your Bronco’s engine concerns on my end if you’d like. Will you send us a message with your VIN and dealership info?

Yes, thanks, I'll send that to you.
I did get a scheduled appointment with my local Ford dealer on the 23rd. They squeezed me in due to the nature of the problem.

I have to ask were you in sport mode? It will rev match and hold revs longer if in sport mode.

I was in Eco mode

I hit the push button to start the (1.5L) engine and, in park, the RPM ran into 4K territory. Shut it down. Tried second time and did same. Now afraid to drive.

Wonder if an engine diagnosis tool will give some info.
.
I will admit rotating the goat mode dial a lot on a recent trip. I kept “over shooting” the sport mode. It’s just a rubber band CVT transmission right? I figure idiot proof.

Will contact Ford contact here.

Thank you for also reporting your issue. This reminded me that I need to post an update.
Ford took my car all day and did not find any issues. I am up to 4300 miles now without further trouble. I did notice that bouncing around the dial can cause the RPMs to bounce too. My problem came while remaining in ECO mode.

No, it is not a CVT.

No, it is not a CVT.

Thank you. Glad it’s not a toy.

I did splash some water on the shifter, and promptly dried the area. Wonder if that could cause this. Drove it 7 hours after that.

Not what anyone wants to hear (classic shrug “we cannot reproduce the issue”
I was parked in the garage.

Escape and Maverick hybrids are the CVT.

NOPE, if our BS’s were CVT equipped 90% of us would not have purchased one.
I would not have even test drove it.

I think your wrong on both counts.
The two models you mentioned have 8 speed transmissions just like our BS’s
I think, thunk, thought.
