She said she would ask for the Julian build date.
She said she would ask for the Julian build date.
Went and took pictures of the bronco and now the driver side window doesn’t automatically roll up or down. I had stay inside to roll it up properly so the rain didn’t fill the truck and crawled out the back door. It looks like Bronco is within the HOT ZONE. Talked to the service guy and asked about a loaner and they said I couldn’t get one cause I didn’t purchase the extended warranty(which we do that right before the factory warranty runs out) but if the salesman had told us that at purchase I would of took it out then. Cause I’ve never had to have it before to get a loaner as long as it was under warranty I got a loaner. So gonna call Ford Customer Care service Monday morning cause due to me driving and hour back home and son has a football out of town I’m not gonna have time today. I talked nicely to service guy and told him I’m on foot and he didn’t care. I guess 20 plus years of loyalty and 12 purchases of new vehicles don’t mean nothing which I didn’t tell him that even thou I wanted too. So I go outside and see a 2022 Bronco Catus grey on the lot for sell, it’s engine had went and they made them but the bronco back according to a salesman that pulled us to the side. I got photos of it too. So frustrated and upset I’ve waited 8 years every since ford was toying with the idea of build the bronco to get my dream vehicle and it’s sitting there undriveable with engine failure.

I believe you asked how long it took to get it fixed…. Mine took 32 days, and they went ahead and replaced the recalled top while they were replacing the blown 2.7.

Notes:
- in October a Ford Lima employee (@Jay3630, deleted soon after) made five posts re 'bad batch of brittle valves' - 'April batch' - see posts #1, #2, #3, #4, #5
- if the failures are caused by 'bad valves', maybe that 'April batch' has been working its way thru the system - then the problems could subside ?
- late October a Ford Service Technician wrote a post re nationwide frequency of failures - he said 'about thirty in the last month . . recorded in the Ford Technicians Forum page'

-- 'Nano valve supplier issue was resolved with more robust design and material changes at the supplier.'

Both of my engine replacements took about 4-5 weeks end to end and I'd consider myself lucky with those timelines. Hard to see how to get it done much faster than that, maybe 3 weeks if a dealer had no other repair work.
The first time was ~5 weeks and took longer because they didn't realize they also needed a fuel pump and then had to wait on that part. My Ford CSR was awesome, got my rental covered, constantly followed up with me, etc.
The second time was about 4 weeks. It wasn't the same valve issue this time but still required a new engine. My CSR this time was not helpful at all - I heard from her once and then never again despite multiple inquiries from me via phone and email. No rental car, no loaner. Fortunately I was able to borrow a family car.
I finally gave up on the Bronco a couple weeks ago. Two engine replacements, ongoing issues with windows, rattling, roof, etc. Loved driving it when I had it, but didn't have it enough. Maybe I'll think about a 2 door as a weekend car in a couple years when things are more dialed in.

I am worried about my 21209 with 12k miles again now that it seems the mileage range is expanding.
Keep im mind that as you get further away from the center of the distribution, your chances of having a failure decrease exponentially (doesn't mean it won't happen, but we are talking decimal places above the 99%). I did the math a few pages back based on the average mileage and standard deviation... Keep driving, I have 35k on mine, it's going to blow any day now... I am sure of it. 
I got the extended warranty, just to get proven wrong.

Are we at 64 engine failures now with the I.G. Post shared by @Math4Fun77? Sometimes it can be hard to keep track.
This thread has been an good source of information. I'm not sure why I follow it because I'm getting a 2.3 7MT and consequently should probably be following a 2.3 Fuel Pump thread. But it has been entertaining to check this thread every few days for the latest.
