Out of the blue my dealer called and the part is in. Too little too late for my camping reservations, but atleast I got my truck back.

My car was traded out by the local dealer. It can be removed from the list. Ford had approved a buy back owing to the issues but the dealer would rather keep it and fix it, and sell it used later.

I'm now in the King Ranch I mentioned, not my idea choice of color, but it has nearly every option possible, AND, with all the goodwill discounts, I'm paying 120$ less per month than my old one.

In other exciting news. The Platinum in Smoked Quartz I ordered 1/6 is finally getting built, 8/10, totally unexpected otherwise I wouldn't have gotten this. Decisions decisions.

Congrats to you both (@70Mach1 & @PeaksFord ) for movement on your trucks (even if a different one).

I drove mine home, parked it and opened the hood. The next morning - no leaks and coolant was at Max. That is a weird but happy feeling.

Got the steering column wiring harness recall done (wiring connector was replaced) and the Trailer software recall done as well. I did note the truck struggled to find a gear leaving the dealership (20-30 mph, 4th gear was in there somewhere), but it settled down after that and the ride home was smooth.

Good luck all and I hope no one breaks my record. @DB63 - we need yours fixed now!

Good lord, I had no idea this was such a widespread issue.

I did not get any CEL related to engine coolant leak (though I did have one for autolamps not working which eventually fixed itself). However, I found there was a pretty good coolant leak when the engine bay fan turn on so loud and aggressively I thought the whole truck was about to take off. Dealer did an "emergency" order and we finally got it here 3 weeks later. Currently at around 20,000km on the truck. Dealership offered by a loaner or free bottles of Motorcraft engine coolant for hybrids. I declined in the loaner (we had a tornado rip through the southern part of the province so there's other people who need a loaner vehicle more than I do) and I'm on my second jug of coolant. Should be getting repaired Aug 11th. Fun times!

Mine got repaired today, but I confirmed it too late to pick up the truck, so that will happen tomorrow.

Let me know of any mistakes. Thanks!

The party finally came for my truck and it was replaced yesterday. The service center at my dealer says it sees what the issue is with engineering and is providing feedback to ford.

The Service Charging System warning magically went away and my dealer says it sees no issues with the battery or alternator so not sure what that was about.

Nice of you that you declined the loaner if you didn't need it. If you can get me your stats for the tracker, I'll add your data.

If by issue you mean the heat exchanger leak, that seems to be what is happening. My repair sheet did not state any other parts.

Good news - that was 2 months on your latest wait. See if you can find what issue the service center found regarding engineering. (Could it be a plastic part bolted to the metal exhaust?.):ROFLMAO:

Seriously though, it would be good to hear what they see.

The blend dates make me real nervous about getting mine next week, mine was 12/27. It took them until now to ship it so maybe it leaked right off the line and they fixed it already? Crossing fingers..haha.

Finally received my new exhaust pipe extension P/N ML3Z*5A212*W and the dealer installed it today. Fixed the P237C code I have had since March 2022. Never had any leaks, but did have the CEL and experienced reduced power while towing or in hot ambient temperatures. No issues so far and will continue to monitor. I did ask the dealer if I could have the old part to retain as a spare in case the new one starts leaking (old part never leaked, just had issues described above). They said they have to hold it for 45 days to see if Ford requests it under warranty otherwise I can have it. Figure it would be a good "spare" to have on long camping road trips, especially if the new one starts to leak or fails, at least I would have a known no-leak spare to get me home. So for me, it took about 4 1/2 months to get the part. So hope is on the horizon for all...
10 days post-part replacement and all operating normal with no leaks or messages. As a side note I was working with Ford Corporate on the issue and as a token of goodwill they provided me with a 4 year 60K mile maintenance plan (starting now) for my inconvenience. Plan takes care of oil changes, tire rotations, brake pads , etc. and routine maintenance items. Appreciate it, albeit after a long and frustrating journey. I also have an ESP purchased when I bought the vehicle so that should keep me covered for a while. My dealer in Janesville, WI was helpful throughout the process as well, but working with Ford Corporate I believe at least gave me another path and offered an additional outlet for my frustration :)

Made me wonder the same thing if the 12/20 week hold overs were leaking PB heat exchangers or other similar QC issues caught on the line and then waiting on parts.

I was wondering if you got your truck. They delivered on 7/28 and you still haven't gotten it?

When you pick it up, snap a pic or two and post them on the build week. We need closure on this saga (and the others still not getting their trucks from that week.)

Glad to hear it's working and Ford worked with you on it. If you can get me your info, I'll list it on the tracker. Good luck!

2022 F150 lariat powerboost
A little under 4000 km later and still no leaks for me
Had the first oil change this morning as well and the service manager met me at check in with the agreed settlement money ready to go
So looks like I finally have everything settled up and the truck is good to go

I also learned it can take a little while for the recalls to get registered as done in the system since I had them do the trailer brake controller recall when it was in for the heat exchanger and it hadn't registered as being completed yet when I was in this morning
