Absolutely agree. This is why I have changed the dealership. I was tired of my previous one (Montmorency Ford in Brossard QC) that replied to almost any complaint like "this is normal, nothing to do". New dealer I went to not only confirmed that they have seen that on _some_ trucks, but my invoice also mentions that the message has been sent to Ford technical support line. I actually even quoted the discoveries published here in this thread.

Next time I go there for service, I will ask them to check the status of this issue. I am sure this one won't go away on its own...unless with the drive shaft

Anyone have any updates on this for their truck? Right before the thxgiving holiday here, I took the truck to the 4th dealership, but I was unable to leave it with them at that time, but I was able to show the service advisor the issue, and after hearing one of the loud clunks, he called his service manager over as well. I showed the service manager my videos of the issue, and as he was exiting the truck, I started the engine and it made a very loud clunk. He said and I quote: "Oh yeah, thats not normal". I dropped it off at the dealership today, so lets see what they tell me.

So the service director met with me, he says that he has driven a couple of f150s that do this, and its normal. He says they called the techline and were told its normal. What BS!
anyone else make any progress, or y'all just gonna swallow?

One fix I was recommended so far was a non-Ford truck But still hoping Ford will come up something before trying that option.

FWIW, my 2018 XLT Screw 5.0 4 x 4 makes the same startup noise since day one. As with most others it will only make the noise when I apply the parking brake while still in Drive and foot on the brake, then shift to Park on the transmission. If I shift into park first, let the Truck rest on the Parking Pawl (my driveway is at a slight angle), then apply parking brake it will not make the noise. Not sure why the drive shaft rotates during start up when the vehicle is in park, Ford/Chevrolet might have an issue with hydraulic pressure leakage in the new 10-Speed allowing a drive clutch to momentarily engage during startup, causing the drive shaft to rotate and tap the parking pawl at startup, thus creating the noise.

I will bug my Service Writer and mechanics at the Dealership I go to, they are top notch and have never had a problem with anything they have done, including installing a new motor in my 14 GT500 under factory warranty.

This is true - and, I think, there was a conclusion that it does make a difference. I am not even sure how exactly do I stop my truck, the brain is not involved in the process I back up on the driveway, push the brake, move the transmission to Park while keeping the pressure on the brake pedal, engage the parking brake and then release the brake. And I get that clunk almost every time.

Another thing I have noticed - now I get a "smaller version" of that clunk when the truck is downshifting. Particularly, in the situation when I want to slow down and it shifts from the gear 3 to 1, sometimes this produces a "clunk". I did read recently about a TSB related to rough shifting which, apparently, requires new transmission software - if that's the case, I will request it to be done when I go to the dealer for the oil change in about a month.

jjandascog, welcome to the clunk club. I just submitted my arbitration paperwork to the BBB concerning this clunk issue. I've been trying to get some of the folks on here with this issue to cooperate and I've sent private messages and public postings to try to get something rolling with Ford, but no one on this forum seems to care. I have had the clunk happen while the weight of the truck is resting on the transmission on an incline and no parking brake set, and while the drive shaft doesnt appear to move, the clunk can still happen. Go to youtube and search for 2017 f150 driveshaft clunking on engine start. Then click on my name to see all the videos, including the clunk while resting on the parking brake. I really hope your service dept gives a crap, because the 3 dealerships here in Austin area dont care at all and said its normal. The dealership Service dept Director at Covert Ford on 183(not manager) told me he has driven one that did it as well. He also told me they called Techline and were told by Techline that the issue was normal as well. Here is the funny part for me. I attempted to show the service advisor the issue, but it wouldn't reproduce. Then as i was about to leave, I started the truck and it did a big clunk. He said "Hold on, my Service Manager has to hear this". He went and got the Service Manager, and again i couldnt reproduce it. He looked skeptical, and i played the youtube videos for him using the trucks sound system. Finally as i was starting the truck to leave, another big clunk! He said "Oh, thats not normal". So i dropped the truck off, then a day or so later, they called me to talk to the service Director (NOT THE MANAGER that had heard the clunk and said "thats not normal"), and the service Director said it was normal. The service manager that said it was not normal didnt join our conversation about my truck. Also, the regional Ford Service Engineer (FSE) was a joke, he wasnt the least bit technical and called the issue "a characteristic". I looked at his education and online resume, he was a glorified customer service person before becoming the FSE. I have emailed many people at Ford directly, engineers, engine and powertrain specialists and others. I have read receipts as well. The only response i get is the same "Executive" Customer service lady named Lynn Aldredge, and she just parrots what the dealership says, "its normal". She has lied to me on occasion and she doesnt even realize i know she lied. She has changed her story about talking to people at Ford about the issue, and her story changes a little each time she tells it. Here is my opinion of the root issue with Ford. The service techs dont make much money on warranty work and/or their level of apathy for the customer's issue is non-existent. I also think think they are just part swappers, most (not all) of the techs just arent technical enough to root cause something like this. Whats worse is that service managers want to make money, they have quotas to fill, and spending a techs time trying to troubleshoot an issue and not making money swapping parts is not allowed to happen. There are dealerships that dont follow this model, but the ones near me do. I would bet a lot of money that if i told them i had a salvage title and the engine and tranny weren't under warranty, they wouldnt say its normal. Anyhow, good luck with your truck, i hope they are more responsive where you live than here in Austin.

, That made me LOL,

I am heading to the dealership this afternoon as my son is purchasing his first new truck, 2018 F150 XL STX 2WD 5.0 10 speed, will be interesting to see if his has the same clunk even though it is a 2WD. My son is going thru the Ford ASSET program to become a Ford Mechanic and has been working his internship at a different Ford dealership that the one we will be purchasing from today. I asked him about the clunk and at his dealership they have not had a truck come back with the clunk as a problem as of yet.

I would agree with you on a dealer case by case basis and it all stems from the Service Manager at a particular dealership as to how his service tech act. When I was a service tech (many moons ago) putting myself thru college, warranty work was my bread and butter, I made almost twice the flag time about 80% of the time and a good service tech will still do the same. My step dad worked for Ford Motor Company for 30+ years on the parts and service side and he would always talk about the attitude of the Service Managers and how a good service manager was everything to a dealerships service department and that a "bad" service department really was the fault of the owner(s) as they usually hire the Service Managers.

While I am at the dealership I will go bug my service writer to see if he has heard of other clunking F150's.
