***UPDATE*** I had all that good news to report last night and this morning it seems as if the noise is partially back. Went to the store this morning and naturally checked for the noise after startup and sure enough it's there. Yesterday I started the truck several times and shut it off checking for it and I heard nothing. It still seems like everything is shutting off after turning the key off as i've not heard a noise but it was a short trip this morning. If & when I get time i'm going to visit a dealer and look for other 12's..sports in particular and start them up and see if I hear the noise. If not, my truck is going back to the dealer yet again. If I do, then I guess i'll chalk it up as normal, however annoying it may be.

Finally got home to the truck today and drove it across town making a few stops here & there and I am happy to report that the dog whistle has been removed from my truck. As I had originally stated it would go for hours after the truck was turned off and I discovered the day the dealer picked it up from my house that it was actually making the noise the entire time the truck was on as well...as soon as you started it about a second would go by and then bam it was at it. Turns out the culprit was (must've been) a faulty gear shift lever. The sales manager said they put their master tech on it (figured they would because of pissed off customer) and he found that even though the selector was in park and the truck would not move and all, that the cpu didnt know it was in park due to the faulty lever and continued sending power to the solenoid thinking it was in reverse. I have no noise what so ever at startup now, while driving, or after parking. I love ford..lol. Seriously though i'm just happy its fixed. I've been the owner for 3 1/2 weeks and this is only day 7 in my posession. I will try and post a few more vids I had tomorrow to help anyone identify with thier noise in the future (or rule out). Tired tonight

Dealer called me earlier and claims its fixed. We'll see. They agreed to split the cost of remote start with me for my troubles, but they wont have parts till Monday so I told them to keep it. I will update when I can after the truck is back. It probably wont be until late next week or the following week until I get back home to the truck.

Thanks autom8r. I too agree with solenoids not whining but this is what the dealer is claiming but they can throw all the parts they desire at it until trip #4.

Hey autom8r, If u still have the service manual available and wouldnt mind looking...is this shift lever just a mechanical assembly or are there some electical parts to it. I figure the shift lever is a mechanical lever with circuitry inside when u choose a gear that then energizes a circuit to the solenoid...is this correct or could you educate me otherwise. Im just trying to understand the likelihood of this fix

Got a phone call... They have ordered a gear shift lever and are expecting it thursday. I didnt really even go into detail with the service guy who called as I am just tired of the whole situation but basically they are saying the gear shift lever is defective (I guess) and its causing the solenoid to stay on after the car is parked. We'll see....

Just spoke to the dealer and I was told the wheel bearing has been replaced (hooray, im jumping for joy) and as far as the whine..im told it is a solenoid staying on inside the trans (so now we're back to it being inside the trans) and they are waiting to hear from ford hotline on how to proceed...yawn

Ok thanks for the info but let me ask you this...If the system only has a check valve do you think its possible that that check valve could be worn/defective and remaining open causing the fuel pump to run for hours (assuming that it is indeed the fuel pump making the sound after shutoff)? So then my next question is what do u think makes it quit squealing whenever it decides to quit. If a spring in the valve is broken or whatever what then allows the valve to hold at some point. If it were like a viscous / thermal clutch setup or something on the check valve assembly..then what you say could make sense and coincide with what I said as it seems like a issue related to how long the vehicle is operated and potential heat, but I certainly dont see that being the case. I am certainly not up to par on ford designs or any manuf designs but I just dont see how this scenario works.

Yeah we know its not a wheel bearing making that noise and I didnt mean to imply that in my post cuz the lady that called me wasnt trying to make that connection either. She just said that they found a bad wheel bearing and they heard the noise I had been referring to but have not been able to reproduce the sound since. I know why they havent though...they've had it sitting in their bay since saturday and have not moved it since most likely. The wheel bearing in my opinion is most likely fine but they want to change out something to make me feel like they did something. At this point its all good....2 more trips to the dealer and its a wrap. I like the thought process on the dump valve though if it is indeed the fuel pump making the noise. Makes perfect sense.

Thanks I dont really have any questions at this time. The dealer called me this morning and said they found my truck has a bad rear wheel bearing. Yet another thing that makes me laugh. This was a cpo vehicle that hasnt even seen 200 miles since I had it and it miraculously has a bad wheel bearing. Then the lady tells me they heard the noise that I was talking about but they havent been able to replicate it. I told her they need to drive it and put even more miles on it and i'll just make the payments. This is such a f@cking joke anymore. I really hope they return it without solving the problem which im 99.9% sure they will. That'll be trip #2 to the dealer..only 2 more to go after that and im done with ford.

I understand how the diodes inside, if fried could allow reverse current flow therefor allowing something to remain powered. However A. I dont have the truck anymore its at the dealer and B. If it were as simple as a diode it would always remain on until the battery saver kicked in on the truck and maybe even beyond that. In this situation what I learned this morning is that it seems relative to how long u operate the vehicle as to how long it will remain squealing after u park. After the 20 min drive home from dealer last night I know it went longer than an hour as I quit going outside after that. After my roughly 8 miles this morning it went on for an hour pretty much exactly. I then drove it for about 4 miles so it would be squealing when they got here to pick it up and it actually stopped while we were all standing there listening to i...so it only went for about 10-15 mins that time. I dont know if this is a heat related issue of some sort that the longer its operated the warmer something gets and the longer it stays powered and squeals.

Basically the fuel pump issue with the whining I would agree with but the noise continuing after shut off not so sure. If it is the fuel pump constantly running I have never in my life heard a fuel pump hit that particular frequency. Also, you would think you would hear the the pump struggling at some point due to the system being pressurized being that there are no fuel leaks or relief valves that im aware of, but the high pitch whine is consistent after shutoff.

Ok so this just keeps getting better. Called the dealer this morning and raised civilized hell. The manager proceeds to ask me what would I like my solution to be...really? So after picking up the truck last night and driving it home at which time I made the posted video above, the truck made the same noise that continued on after it was shut off. This morning after getting off the phone with the dealer I went out to document all noises properly for myself and this is what happened... 1. Started the truck and a second or two after being started at idle I opened the door and heard the noise (high pitched whistle). 2. Shut off truck and noise stopped (as I had stated before had to be driven to continue after shut off). 3. Took the truck around my neighborhood (not letting it warm up to temp) and parked it again...no noise after shutoff. About 1/4 mile. 4. Cycled key on and off several times, as you would to prime your fuel system or suck every drop out of your tank when low on gas. No noise. 5. Drove truck about 7 miles around town to let it come up to and operate at temp and returned home and parked it, no noise after shutoff. Started a few times for 10-20 secs and u can always hear the whistle while its running which now might sway me to believe in the fuel pump being that culprit. Also I could hear the pitch of the whine change as I put load on and off the engine so I would definitely agree with fuel pum being the source of the 'whistle while vehicle is running' (which is certainly horrible) but I guess ford's stance is this is normal. Normal trash...i digress....... 6. Stroke of luck my son wanted cereal and we had no milk so I went around the corner to the gas station (about 1 mile round trip, if that) and got milk. Returned home and parked it and she's currently sitting in the driveway singing ever since. Update literally just went out to do another 15 min check and it quit. So it went for 1 hr this time. I had timed it before taking it to delaer once, and it went at least 2 hrs but I had stopped checking, so I guess I should smile due to this improvement. The dealer has guys en route to pick it up and take it to their dealership. Ford is seriously working on losing a customer here. I have owned 4 fords in my life and dont think i'll ever buy another.

It is not coming from the back and its such a hard noise to pinpoint because of the frequency but its definitely from the front or middle of the car. They supposedly used a stethescope in the shop to narrow it down to the bcm. Then they supposedly replaced it, telling me that it wasnt shutting off when the key was turned off and thats where the noise was coming from. In the vid u can hear the whistle clearly and even now its been a couple hours since i've been home and i'd bet its still going. It lasted for probably 2-3 hrs before I took it to the shop this week. trim.7D9E2C65-F48C-4C88-B490-0DDB2B1262C7.MOV

Well just picked up my edge tonight finally after being at the dealer ALL WEEK waiting on the body control module to come in which is what they diagnosed as the cause of the 'dog whistle' sound. NO CHANGE. Started it up and checked to see if I heard anything and nothing (same as before)...but when I drove it home and parked it...bring on the noise. Same exact noise as prior to going into dealer and at the same time (after being driven). Startup and idle wont cause the noise, only after being driven. What a joke. I will be calling the dealership I purchased it from tomorrow morning and we'll see what happens
