    My 05 gt auto mustang is making the whine and howling sound loud enough to hear over the sound of the radio on at average volume. it sounds like it is coming from the back of car The dealer ship has put a new crown and pinion gear plus bearings in. this did not rectify problem. So from what i have read in this forum the exhaust hanger or auto transmmision need replacing Please send more info on this problem you mustang owners, it is much appreachated. thanks

    Yes graphicguy, we do get some sounds with a powerful V-8 that most other cars might not have. Of course there is the exaust, and most people WANT that rumble. Also, espicially in 2nd gear, you can hear the "whine" coming from the tranny, and it is damn welcome, for it is a whine that you get with a muscle fact, it reminds me a little of the whine you get with a drag racer equipped with "gear drive", and I love it! :) I think most Mustang owners love it too. But vibrations that are not supposed to be there are irritating, and I must give credit to Mustang owners, because I think most of them can tell the difference between a sound that is supposed to be there, and a sound that is not supposed to be there. It's irritating when you go to a doctor, and he says "there's nothing wrong" when you KNOW that there is, and you know he probebly knows it, but dosen't know what the problem is, so he will conveniantly dismiss the problem saying it is normal....and that causes several problems...

    For one, no progress can be made if a technician won't admit that there is a problem. For another, it makes you feel like there is something wrong with YOU when your told 'nothing is wrong", and that can be degrading. But mainly, when you spend $30K for a car, you WANT THE DAMN THING FIXED as fast as you can, because it puts a damper on owning your brand new car you worked so hard for, and you find yourself asking "why didn't they test the car more throughly BEFORE they released it to the public?...and "can they fix the bugs before the new car smell wears off"?

    I know we are all human and make mistakes. But the bottom line is this: Any new car design will have many bugs in it. Ford should of tested this more througly before putting it into showrooms. That was just sloppy.....

    t.....I wasn't directing my comments to you, specifically. I was just making a general statement.

    My previous car was an RX8. Rotaries are notorious for "flooding". Post upon post regarding the engine flooding was made. Using that as an example, the dealer should have warned the buyer that you have to warm the car up first if you're taking it on a short jaunt (less than a couple of miles). They didn't. I blame some of that in the dealer. The owners should have also read the owner's manual warning against shutting down the RX8 when cold. That would have allevaited much of the problem.

    Talking about the Mustang (specifically the GT), I've found it to be smooth running. If you've got some untoward vibration, then by all means, have the dealer service dept. take a look. If one can't find the problem, go to another.

    Having followed the '05 Mustang's development, over the last 3 years or so, I'd say it's one of the most thoroughly tested and engineered cars Ford has brought out in recent years. From what I've read about (in numerous other Mustang boards), whatever issues the Mustang has had, Ford made running changes at the factory to fix quickly. For the most part, those built from March on, have had few, if any problems.

    While I know you must be frustrated with the vibration you're experiencing, I don't think it's as common, nor as widespread as you believe it is. It sounds like your dealer service dept is "hot on the case" and has narrowed down, at least, part if the issue. They sound like they can get the rest taken care of, too.

    Personally, my GT is probably one of the best built cars I've owned over the last 5 years. It's been perfect since the day I drove it off the lot over 2 months ago. Talking to other owners both locally and throughout the country (via the other Mustang boards), I think the vast majority of us feel the same.

    The only thing I've had mine back to the dealer for was to activate the "windows down from the remote" feature that comes with active anti-theft option. That was done the day after I took delivery (and after reading the owner's manual where I found out about the feature in the first place). It took all of 5 minutes.

    I appreciate what you are saying. I know you were only making a general statement, and I was only replying on behalf of some frustrated owners. I know there are quite a few frustrated owners, because I have been reading this forum. And I know my vibration problems are more widespread than you might think, because my dealer told me that Ford told him the problem was widespread!

    Mabey it was well tested...but mabey not quite well enough. Those little bugs are not earth-shattering I know, but it is frustrating to order your car, wait two months only to have several "bug-a-boo's" when you get it. What's worse is that Ford was hiding this one ;) , according to a guy who posted earlier around page 4 or 5, and according to my tech! However, your right my tech is on it, and over time I'm sure we will work the 3 bugs out that I have. Now that I have said that, let me agree with you on this...

    This is one car WORTH finding the bugs and fixing! It handles like a track car, it rides like a luxory car, it sounds very sweet, runs very smooth, and the looks....well more people in this town will turn to look than they did when I owned a new 98 Corvette! :) The interior is wonderfully nostalgic, very functional, and quite beautiful. I'm having more fun with this car than I did my Vettes, and the tires for this are a LOT LESS.
    All in all, this 05 Mustang GT is a very nice package. If it wasn't, I guess I wouldn't have been so upset at the 'bug's" in it.

    Hi there,

    I just got my first '05 gt automatic transmission last thursday 02/06 and allready seem to have my first problem. It's the same described here; When form park to reverse or drive on my automatic shifter it makes a clunk sound.

    Anyone had this same problem and if so, anyone got it fixed allready? What was the cause?

    Besides that, it runs gr8!

    My Mustang was built in Oct. 04 and was purchased Nov 6th. I have absolutely loved my mustang considering it is my first. I've been experenced many of the same problems that others have had.

    I've been having the gas tank problem since I first bought my car. I have since had it replaced and now the new gas tank is having the same problem as the original.

    Also I am about to have my 3rd radio installed. The original would eject the CD and say bad disk and also while playing a song it would stop and skip to the next track for no reason. The 2nd radio installed worked fine until I realized that the lights wouldn't work and the speed volume doesn't work either. Without checking it out they told me that they would replace it again.

    Now here's one thing that I haven't heard anyone talk about and I was wondering if anyone else has had the same problem...... When my fuel gets down to 3/4 tank full, my gage will go to E and my gas light will come on. It's happened on my original gas tank and on my new gas tank. Ford has ordered me a new fuel sensor and I'm waiting for it to come in to replace it. I'm about to the point that I am starting to check out the :lemon: laws for some information.

    I took my '05 V6 in to dealer for 5000 mile service... I had a couple of things I wanted them to check. One was a humming coming from the rear at about 40mph and above. BUT I only heard this when I had my foot on the gas. This problem started at about 2500 miles. I thought it may be the tires at first, but when I'd take my foot off the gas and coast, the sound went away. The dealer called the Ford main office and described the problem to them; the office told them to order a new rear axel assembly and replace the entire assembly rather than taking the thing apart (under warranty). They've had my car now for 20 days....... I had to also get the gas tank thing fixed, and that's the part I've been waiting for on back-order.... Hope everything goes well for you..... but your problem sounds very similar to mine.

    That 3rd radio you are about to have installed will not work either if the technicians don't read the TSB and do the proper programming of the OLD and NEW unit. Your 2nd radio isn't broken, it wasn't programmed. Tell you service manager to have his/her technicians READ THE TSB's. Once the proper programming happens, the lights in the buttons and speed volume will work fine.

    This same thing happened to me and it really pisses me off that the technicians don't read TSB's when you bring in your car. Shouldn't that just be standard operating procedure whenever you bring your car in? Now you are about to take the trouble to bring in your car and be without it for a day because some lazy technician didn't read the TSB that SPECIFICALLY says if your don't do the proper programming the lights on the buttons won't work. :mad: .
  • hot_rodhot_rod Posts: 13
    I figured that it was something that wasn't connected or something small like that. I thought it was kinda weird when I told the service dept. what was going on when I got there and after waiting for over an hour the tech came and asked me what it was doing also. Seems like to me that they would rather get rid of you asap instead of making you wait forever and then do nothing while you wait. I've had problems with other Ford dealers on past vehicles, but I think that this takes the cake.

    Here's my list of issues with my 05 stang V6 automatic:
    Exhaust Vibration - fixed
    Front End Popping
    Paint Stripes Peeling
    Slow Fuel Fill
    Passenger Air Bag Light Stays Lit
    Hesitation in Acceleration
    Clunking Sound From P to R

    Other than that, I love the car.
  • jaddayjadday Posts: 4
    Looks like we're having the same problem with the clunking sound. I'm taking mine 2morrow to see what's wrong.. I'll keep ya'll posted...

    I have a V6 Coupe. Built in April, 05.

    I have it in the shop right now for a couple of issues, but they called and said it's ready to be picked up now.

    The only thing major is the fuel tank. I have filled my car about four times so far and it’s only done it to me at the Kroger pump.

    I went to fill it from about 1/8th of a tank and it cut off on me twice right away. After that, it filled fine until I got to $14.99 and it cut off. I didn’t figure this was enough gas, so I tried to add a little more and it overflowed.

    I got in the car and I had only about 5/8 tank. I went to Citgo and filled it the rest of the way without incident.

    They’re going to replace the tank.

    Anyways, the only other issues I’ve had are that there is a small part of the driver’s floorboard that pops when pressure is applied to it. Like a piece of the metal above the floorboard, but under the carpet, is bubbled up or something. Similar to those little popper things that you train a dog with or use to “buzz in” in a board game.

    Also the passenger door is rubbing against the striker when the door closes. This isn’t a big problem, I just want to get it fixed. When you close the door slowly you notice that it rubs it and the door actually lifts up ever so slightly as it closes.

    The last thing is the drop glass on the driver’s side is rubbing against the frame when it opens.

    No driving problems at all. I’ve got about 1,100 miles on it so far and it has driven flawlessly.

    Anyways, they said it is done now and they replaced the tank. The driver's door drop glass is fine. They looked at others on the lot and they rub the frame as well. They adjusted the passenger door and I will have to schedule an appointment with the body shop about the popping in the floor board.

    I'll let you know all the details after I pick it up.
  • I also took my auto v6 in for the clunking sound. They told me it was normal for that car. They even had me try 3 new cars on the lot and they all had the same sound from park to reverse. Let me know what you find out. I still do not believe that a new tranny should sound like this.

    In August of 2004 I placed my order for the GT Mustang Automatic. In four months the car appeared at the dealership. It had everything wrong with it that has been discussed here, and I refused to take delivery of a car with so many things wrong with it. This car also had one problem that I have not seen in this thread: The rear suspension bounced up and down so hard that I thought that Ford had forgotten to install the springs. After reading this entire thread, I am glad that I would not take this car. I decided at that time to wait for the 2006 car and see if the problems have been corrected. It seems that little if anything has been done by Ford to this date. Car & Driver tested the convertable recently, and went on and on about how Ford had corrected the rough ride of the coupe by several suspension changes, and my question to anyone here who might know, is has that change been incorporated into the 2006 GT coupe. I intend to order another GT coupe, but only if these problems have been corrected. Does anyone here know anything about what changes might be made on the 2006 cars? I really feel that this Mustang would be a great car if it worked right. Who wants a car that spends most of its life in the dealers repair shop? In my opinion, a car that is not reliable is worthless, and the makers of such a car should be punished by the consumers not giving them their money. They would soon get their act together if the buying public stayed away in droves. Look at GM.

    Hey Guys,

    Anybody have any luck with the hesitation problems on the GT automatic? I swear there is a hesitation in the low gears. Also when I am in stop and go traffic seem to rev engine after braking and getting that feeling of a "thunk" from the engine. Do you guys think driving with overdrive off would give the GT a smoother ride in the stop and go traffic.

    Any ideas?
  • graphicguygraphicguy SW OhioPosts: 10,137
    I think there were running changes made to the suspension (both coupe and convertible) from those that were tested by the trade rags with early models. While Ford won't say, I don't think there were any major changes to the suspension, just tweaks.

    That said, the Mustang is NOT going to ride like a Lincoln. What you should notice is the ride is firm and the suspension planting the wheels firmly on the road.

    Mine was built March 23. I've never noticed any "bounce" in the suspension at all. Maybe the one you drove had a broken shock from hard test drives?

    I do think some earlier builds had the slow fuel fill and skipping shaker stereo, but I believe the changes made at the factory from the end of March going forward, fixed these issues.

    No changes to the '06 aside from colors and wheel/tire options.

    Try this on...

    I order my GT in a beautiful "Mineral Grey" and pick it up, and I notice the light bounces differently off a small part of the front of hood (about the size of my hand) then it does the rest of the I take a closer look. I go to the car wash and the problem is still there, and I realize my worst fears are confirmed: It looks as if some DOPE mechanic shut the hood leaving a bit of dirt on the hood, so then stupidly wiped the dirt and grease off with a rag, destroying the clearcoat in that area. I don't kow if it was in Michigan, or here at the dealership, but after spending 30K this IDIOCY does not make me happy. Going to FORD right now and see about it...
  • Oh boy, that hurts. My GT is the same color, and I'll wash it whenever it gets dirty. :P
  • hughes200hughes200 Posts: 7
    I thought the stiff ride in the rear suspension on my V6 was the way the car was designed. After reading some of the posts, it seems like it's not suppose to bounce if it goes over a small bump. Has anyone had any corrections made to the rear suspension to get a smoother ride?
  • snakerbillsnakerbill Posts: 272
    Graficguy suggested that my car ( which I did not take) had a broken shock, or perhaps I was expecting a softer ride. None of these things are the case. The one I ordered was so stiff that even the salesperson agreed that it was way too bouncy, and when Consumer Reports tested the 05 GT, they too said that it was too harsh in the rear. Ford cheaped out by using a solid rear axle instead of IRS, and they gave a bunch of hot air excuses for the 50 year old design that makes no sense in the 21st century, and the more I think about the Mustang, the less inclined I am to order another one. When I refused to take the car I had ordered, I went and purchased a 05 Honda Accord EX V6 coupe, and after 22,340 miles, it has never been back to the dealer for anything except oil changes. It has IRS, a 240hp engine, a five speed automatic and every luxury item known to exist, it is silent, fast, fairly good handling, with excellent brakes and on trips, it gets 32MPG. I got this car as a substitute for the Mustang until Ford cleaned up their problems, but the more I use the Honda, the better I like it, and the chance of my ordering another Mustang seem to be fadeing away. I may try the convertible, but I think I will stay away from the coupe. It is just too stiff. I just wonder how many of you guys on this thread wish that they did not take delivery of their car, or wish they could get their money back. I would really like to know the answer to that...Anyone?? This car just has too many problems to give Ford my money,

    "The one I ordered was so stiff that even the salesperson agreed that it was way too bouncy"

    Well, I'll say you and the salesman must have an awful sensitive bodies. Today was our day to go an p/u the long awaited GT convrt. My wife (who's car this is) drives a Chrysler T&C Ltd Minivan and I drive a Taurus. Neither had ever driven the GT prior to ordering. We drove it today for the first time and let me state that one of the first things that impressed both of us was the smoothness of the ride (particularly on bumpy roads). My wife even indicated she thought it rode much smoother than her Minivan and that doesn't have IRS. Maybe because it's a convertible, but we were both impressed.

    "More I use the Honda, the better I like it, and the chance of my ordering another Mustang seem to be fadeing away" I'd say go drive the convertible it'll make a believer out of you.
  • gtforme2gtforme2 Posts: 23
    First time ever driving the new GT was today when p/u'd up Windviel Blue model with the auto trans. It's been so COOL driving this thing since. Absolutely loving it. The sound of the V8 needs to be heard to believe, it's the sweetest thing.

    For fun tonight, I really jumped on it leaving an empty parking lot (back end of airport), had TC set to off, then put it to floor (acting like an imature little kid, this car does that to you) and although super quick takeoff couldn't spin the tires. Seems like should have gotten the Stick if wanted to that eh? Just curious if anyone else tried this and is that just something not going to happen with an Automatic? Also, car does seem to hestitate (when stepping on gas) little bit which surprises me, but when talked with Sales guy he didn't have any ideas, other than engine is new and maybe needs to have some time on it to eliminate the hestitation? Appreciate some feedback on this and wether I should be concerned at all.
  • Regarding noisy rear brakes, I had that. I took it to my dealer and they replaced the pads. But I think that was not the cure. The tech also put swirling grooves on the rotors. It looks bad but this is a good fix. That was 3 to 4 months ago and the noise has not come back. :)
  • graphicguygraphicguy SW OhioPosts: 10,137
    If you like the Accord more, looking for 30+ MPG, soft ride, quiet, etc, I'd say you were never a good candidate for the Mustang. Accords are fine cars. They aren't performance cars, though. The Mustang is. It's going to have a firm ride. It's going to handle very well. It's going to be loud. It's not going to get 30 MPG. It's going to be "in your face".

    I wouldn't think that anyone who is a performance car fan would be satisfied with an Accord or Camry or any car of that ilk.

    Enjoy your Accord. I don't think a Mustang or GTO fan would consider one to meet our expectations of what we want out of our cars, though.

    I never said that I liked the Accord more than the Mustang. I said that I liked the Accord on its own merits, and a Mustang with all of the problems stated on this thread is not a car that I would want in preference to an Accord which has no problems at all. I am very familiar with performance cars, and I have owned several Camaro Z28s and Mustangs of prior years, and I know what to expect from such a car, and I can tell you that the 2005 Mustang which I would not accept was not right. The last performance car I had was a 2002 Z28 Camaro, and It was a very good car from day one. It had very few problems, (alignment from factory was off) but other than that I drove it 63, 000 miles with no trouble. My last Mustang, traded for the Z28 was also a very decent car and a body creak was the only problem I had with it. I am telling you that the 2005 Mustangs V6 and GTs are just not right, and you can make excuses for them if you want to, but I will not spend my cash on a car with all of the problems mentioned on this thread. Also, I find your assumption that I have no knowledge of performance cars, and your put=down of me because I made a comparison between a reliable, fuel efficient car and a car which has all kind of problems just seems to me that you have your mind made up and you do'nt want to be confused with facts, or another view of reality. Yes, the Mustang GT is faster, and handles better when it works, it just don't work often enough.You may like getting your car fixed so many times, but I have better things to do with my time than standing around in the dealers shop hoping he can find out what is wrong with the car. If Ford starts producing these cars without all the problems, I will be getting another Mustang, or even, by that time a new Z28 Camaro. Word is, that they (GM) are considering a new Camaro on the new rear drive platform, maybe that would wake Ford up, I hope so.

    I've had my 2005 GT, manual trans, since December. It has always had, among other problems, a clunking noise in the rear-end, especially when turning. I see alot of people here heve this problem, has anyone had it fixed yet? A Ford Racing Performance "Tech Advisor" at the Nostalgic Drag Races this weekend told me Ford knows what it is but he "wasn't allowed to tell?" I'd like to know if anyone has gotten an answer.
  • jaddayjadday Posts: 4
    Well I went to the car dealer but believe it or not the clunking sound did not sound there :mad: I couldn't believe my ears at that moment and untill today it didn't come anymore neither. I do believe too that it wasn't a normal sound but I hope that it stays this way..

    Besides that, now, the dashboard (interior upgrade package) has been tickling sometimes by the passenger side. I think/hope this is easy to fix by my dealer. Also when running like 30 minutes and then taking a left turn, I've starting to hear a strange noise in the back. It's like a gear on gear sound.

    Anyone has heard this sound? Besides these ones, I still DO love my 2005 GT. :)
  • m1miatam1miata Posts: 4,556
    From the talk here of all these problems, I take it a best bet is to buy a pre-'05.
    Looks like the typical two to three year blues for domestic new model cars. Oh
    well, the more things change, the more they stay the same. - Loren
  • tmerrisstmerriss Posts: 42
    the "ticking" noise by the passenger side is a problem I had too but I too care of it. Do you have manual tranny?

    It was bugging me and I just could not figure out just where it was coming from. Then I noticed when I shifted into second gear, the sound "broke" for a second. My radar told me to look at the shifter. It seems I had the shifter twisted to the left (toward me), which is something I did on purpose weeks before because I liked the way it looks (the manual shifter is easliy turned either way if you haven't noticed). It seems the leather shift boot which was slightly twisted (because I had slightly twisted the shifter) and it was the SHIFT BOOT making the sound! :surprise: I strightend the shifter and no more problems....
