I’m at 84,000 miles. ???. Does anyone think there’s any chance Ford would help with fix or should try to find a money tree? ??‍♀
Don’t want to get your hopes up but you can always negotiate with Ford

you are well beyond the 60k powertrain warranty however you can arm yourself by reading through the posts at the link I posted earlier - this will tell you there are a number of owners experiencing the same issue but of course the number of owners you will see that posted will be a tiny subset of the >500,000 Bronco Sports Ford has sold since 2021. You’ll also see the issue affects more than 2021 and you could argue with Ford the issue likely could impact all model years 2021-2025

(only Ford knows how many actual vehicles have experienced the issue)

Your owners manual provides an escalation section - I would try to negotiate with Ford and see if they would accept a sharing arrangement such as a 50:50 split where you pay 50% of the repair cost (keep in mind Ford’s “50%” split is much less than yours because you have to pay the full price for parts and labor while Ford of course does not) - often Ford will do such as split with the dealership service department (you at 50%, Ford and the dealership at “50%”).

Or maybe you would end up paying more like 70% because you are well over the 60k powertrain warranty but I suggest you start at 50:50.

It can’t hurt to try and if you use the escalation process and keep pushing to get a resolution you might get a decision in under a week if you are persistent in a nice way

Good luck!

I just got my car back today Tuesday, 7/22/25 after dropping it off last Tuesday, 7/15/25 for the RDU clunk. They performed the TSB-2386, replaced vent hose and flushed/refilled rear diff, and it seems good now. The paperwork was all set with a total amount due of $0.00. They basically said that if the noise comes back they'll replace the RDU. Part of me hopes it fails but the other part of me doesn't want to be bothered. We'll see how that works out.

I also got the recalls for the AGM battery and the BCM update. I had no problems with my 1st battery and I would've pushed it farther had the RDU issue not come up. It is nice though to have the assurance of a free new battery after more than 3-3/4 years.

Once I got home I had a set of Powerstop Z36 front/rear brake pads and rotors waiting to be installed and also the caliper pin/bushing set I got the parts for the rear brake moan TSB. I can't speak of the quality quite yet because I had to stop due to the loss of sunlight and a stuck rotor on the last wheel. I'll continue in the morning when hammering on a rotor is less distracting to my neighbors. I was thrown back a bit by the fact that all of my caliper pins were completely void of any signs of grease. I do recall reading of this here from some other members here. It kind of makes me wonder if the noise would be remedied just by lubing the pins rather than the redesign of the stiffer lower bushing. Ah, who knows? I am excited to have some nice new, and hopefully better, brakes. I'll report on the brakes after the break in and few miles of testing.

Wow, just traded our 2020 Escape in for the 2025 BS. It was making this noise you are describing! We had no idea! Dodged that bullet! For now...

They did the hose fix for me. If the rdu starts to go again, I'm getting a gearbox and ecu from a salvage fwd Escape. ?
I never need awd anyway.
Actually the torque converter is starting to act weird too so it might not be a bad idea.
