Yes. My 2021 had it. Sounds like it's coming from the speakers. Mainly the driver's side/forward area. I too complained about it with no answer or resolution. I traded in for a 2024 last year and it too has it but seems to be less aggressive. I went to the Ford ST SUV experience in Park City Utah last year and had a change to drive a 2019 ST for the day. I also noticed the sound, but it seemed to be much less than my 2021/2024 so I assumed it was normal. Very irritating and seems most noticeable when the car downshifts from 3rd-2nd-1st. My solution was to turn up the music. Jim

OK this is a good thread for me to ask a question. In the event that I wanted to buy a diagnostic code reader for download to my iPhone, which one is best for me. I have a 2024 Edge ST. I don't mind paying for it as the free stuff is usually very basic. Bottom line, what diagnostic program would you guys recommend for my vehicle. Free or not, I would love to have it on my phone. I also would need a Bluetooth adaptor. Thanks for the advice. Jim

Davidoo I have a 24 ST and mine does have the cooler with the hoses and electric motor that circulates the engine coolant through the PTU. My 21 ST had the same configuration. When you shut the vehicle off this electric motor continues to run and circulate coolant through the PTU to possibly help with heat soak. I climbed under the car after I shut It off and heard the electric motor running. I don't know how long it runs. Personally, I wouldn't worry about the studs. Ford wants to make as money as possible so of course they want them changed. They could probably be re used multiple times without any issue. Be sure to use blue Loctite and torque them to spec. What I can't figure out is why your vehicle does not have the cooler. Also, I don't know how much the cooler helps as it takes circulates hot 200-degree coolant through the PTU. How hot does the PTU fluid get? I think Ford attempted to do some last model year fixes to help the heat issues they had with the PTU? Just unsure why your model year did not have this mod. One good thing, your setup allows to drain the PTU fluid easily,

I use my parking brake all the time. Especially when parked on any type of hill or incline. It is there for a reason.

Wubster100 thank you for the info. I too could not find that in my digital owner's handbook. I did see on some previous threads that there are some possibly better alternatives via Redline or Amsoil. One of the popular ones was Redline Shockproof for the PTU?

Thank you so much for breaking that down for me. I just don't understand why Ford would do that, unless there is a safety issue?? I am recently questioning why I bought a Ford product, other than the fact that it was in my heart to buy an American built (assembled) vehicle, Especially with all the reliability issues compared to the foreign competition. I really love my Edge ST! I am blown away EVERY time I drive it. I sure hope I made a good decision.

Sorry for being ignorant, but what does this mean in journeyman's terms. What would the reason be for ford to do this? I have a 2024 model, so I am curious to what is going on with Ford.

There's a very good chance that the new tires and alignment will cure the issue.

I bought a 2021 ST and it was delivered to me in September of 2021, which means it was probably one of those timebombs. It had some weird transmission issues which scared me and they could never resolve, so I traded it in for a 2024 last year. Looks like I may have dodged a bullet.

Jetboy 47, I recently acquired a FT4Z-581178-C and have a 2024 ST. A big Thank You to rafeeki for selling me his extra one! I have not yet installed it, but from my measurements and visual observation, it will work. The screw holes and light plug cut out match up. I may have to do some slight modification to the center area around the hitch, but it is plastic and can be cut out very easily. I am planning an install soon and will post my results. If you can get either one (-C or -D) I believe the D would be the exact fit and no modification would be needed. But since they no longer exist, get whichever one you can at this point. I was just at my local ford dealership and there were 2 2024's on the floor. Both of them were missing this part. Shame on Ford for doing this to a brand-new vehicle.

Might have got a little off track. I was referring to the hood insulator blanket. Not the engine cover, although it does look pretty nice. The hood insulator blanket doesn't do much for sound, but it looks so much better. Also, I think it protects the paint from heat damage. Thank you to this forum!!

So sad to see Ford delete needed items from newer model year vehicles, shame on Ford.

I agree. With tires you get what you pay for. I was lucky enough to attend the Ford ST/SUV experience in Park City Utah and put the ST with P Zero tires to the test. It was about 75/78 degrees, and they are awesome in warm weather. They stick like glue. Hard to break free until you force them. I only have about 6800 miles on my ST so I don't have much input on the lifespan, guess it depends on how hard you drive. I live in so Cal so they are good tires for year around use. They do seem a bit rough riding and noisy, but I don't have anything to base that on. I do plan on replacing them with Scorpion Zero all season tires when the time comes. From what I have been able to research they are a good all-season alternative and give good all-around performance.

Thank you for all the great info. Haz directed me to another thread, and I was able to locate one through another forum member. The part number he has is KT4Z-5811778-C which I believe can be easily modified to fit. I too had to order and install the missing hood insulator blanket. In addition, the little rubber mat that goes in the forward passthrough of the center console was missing. It was about 45 bucks! And the little plastic tray that goes in the center console wasn't there. What a joke. Shame on Ford for doing this. Do they really want vehicles out on the road with missing parts? Let alone parts of the vehicle flapping around while driving down the highway? Sad.

Davidoo could you give me the part number. Mine has the factory installed tow package.
