Ford Mustang (2005 & newer) Problems and Solutions

I just bought a 2005 mustang 3 weeks ago and I want to share so far fords first year production "bugs" with you. With 250 miles on the OD, I went for my first fill up and the pump keeps cutting off. I tried 3 different pumps at 2 different stations. There has to be a problem with the filler neck. The floor heat and bi-level control doesn't work properly-stuck on bi-level. Anybody else have this?


  • We have had ours about a week now. No problems so far, except for people stareing. I've read on other forums where other people are haveing the same problems as you. I don't know how accurate this info is, but, I heard that Ford had been replaceing the gas tanks, but they have stopped. Try to turn the nozzle upside down when fueling, some people say this seems to help.

    There is a TSB regarding the gas pump early shut off. Dealer should fix under warranty. The ones coming off the factory floor now should already have a fix. I've had other cars that had "premature fuel shut off issues". As suggested, turning the fuel nozzle upside down or slightly sideways usually cured the issue.

    Haven't heard about the heater issue before. I'm sure your dealer can fix that under warranty, too.

    I just got my 05 coupe 2 weeks ago and am having the same problem with the floor and defroster - it seems to be stuck on defrost. Did you get yours fixed?

    Got a GT about a month ago and I love the drive and the looks I get - well you would think it is a fararri. One problem that I have is it has some dash board and driver side door rattles/vibrations. Every time I hit a bump I get these annoying vibration noises and it's driving me crazy. I'm gonna break down and bring it in and ask if they can do something but it's one of those things that will probably be hard for the technician to reproduce. For the most part the interior - even on the GT is cheap plastic, low budget. My F150 has a nicer interior!
  • I checked with the dealer 2 days ago about the heat defrost problem. I was told Ford is working on it and still has no fix. P.S. I know this is out of order(I am a male) I get asked if this car is a "chick" magnet. I say no, but I sure get alot of guys checking it out.

    Well I noticed a few things, like my CD skips, the fueling shuts off and my clutch seem to slip sometimes. I did a 2nd gear burn out and it burnt rubber real fine one night, and another time the clutch didn't seem to engage and just smelt like burnt clutch, so I haven't tried this anymore for now, but it does great burn outs in first and lays rubber in 2nd around 6000 rpms, other than that I think I may have had a clutching mishap and everything is just fine, but still leery about that second burn out in 2nd gear. It could be time to look into a better system, the only upgrade was a SCT Excalabrater Flasher system, its made a world of differents with the gas pedel no more half way throttle at launch it full throttle baby.
  • What is a TSB? I can go to the dealership and under warranty they will fix it so it won't cutoff halfway during fillup? It bugs me so bad.

  • graphicguygraphicguy SW OhioPosts: 10,276
    TSB=Techical Service Bulletin. When was your's built? Mine was built on 3/23. They had the "fuel-up" issue corrected already.

    Your dealer should have the TSB and should be able to correct it if they've got the right parts in stock. If not, it will take them a few days. It will be done under warranty at no-charge.

    A TSB is a recommendation from factory to dealer. The dealer is not under any warranty obligation to do what the TSB suggests.

    How is the throttle by wire working? Can you give the gas a little blip on down shifts to match the RPMs? Is the response instant? How about dropping speed after you let off the gas? Never owned a car with that system. They have used it on Corvettes for some time. Still not sold on electric steering assist. Anyone know if Ford is getting into that?

  • graphicguygraphicguy SW OhioPosts: 10,276
    Can't comment about electric steering, but the "drive by wire" in the Mustang works instantaneously. If anything, the response is quicker than the usual mechanical connection between throttle and response.

    If you are ignorant enough to do burnouts in 2nd gear then you should be prepared to pay for premature clutch wear.

    I am getting a Mustange V6 coupe built on 18 Jan05---When did they fix the fuel tank problem??
  • silvergtsilvergt Posts: 3
    I read in another forum that they started putting the new tanks on the cars on Jan. 24.
  • datangdatang Posts: 5
    We haven't had a problem with the gas tank, but we have had a problem with the cd player acting crazy. My 3 week old v6 has been at the dealership since Monday. They are replacing the cd player. My other problem is a noise in the back-end when I engage the shift from park to reverse. Dealer claims there is nothing wrong with the car. Sounds like a U-joint problem. Any clues?
  • graphicguygraphicguy SW OhioPosts: 10,276
    Mine was built in March. I've had no issues with gassing it up. My Shaker plays fine. I don't hear any noises in the driveline. So, in short, I have no clue what's up with yours datang. I'm assuming it's an automatic tranny?

    Mine is a manual trans. It works great.

    I don't know that a new car would have a u-joint issue. What's it doing? What kind of noise is it you're hearing? If the dealer says it's normal, have they given you an explanation of exactly what you're hearing?

    Yes, mine's an automatic. There is a knock coming from the back-end when engaging from park to reverse. The dealership's explanation to us is that the other 'stang on their lot does the same thing. I beg to differ with that response. I've been able to listen to 2 other automatic '05s this weekend & those cars are not making this noise. Anyone whose around when I put it into reverse questions the knocking sound & most have said it sounds like the u-joint is bad. The dealership's maintenance manager heard the knock, said they checked it out but found nothing wrong & since Ford has not posted a bulletin on the noise, there's not much they can do about it.
    Totally frustrated & disgusted with our local Dealership!

    Just got my new Mustang V6. I do have the fuel tank problem! Nothing seems to work to get the gas in except "trikling" in the gas oh so slowly. Also, at times when accelerating from a complete stop it acts as if the gas just cuts off and then it "catches" again. Doesn't happen every time though. My Shaker 1000 Cd does act up at times and I do have a "thunk" when shifting from reverve to drive(automatic Trans). So I guess I'm so lucky to have ALL the problems. I am getting nervous about owning this possible "lemon". Tell me something good here!!
  • graphicguygraphicguy SW OhioPosts: 10,276
    Tell you something good? OK, all those issues are minor and are known. TSBs have been issued by Ford for the fuel problem. You might try turning the fuel nozzle upside down when you re-fuel. That seems to solve the issue in the short term.

    Your Shaker needs a new head unit, also known by Ford and a simple swap out by your dealer.

    The "thunk" you're talking about seems to be an issue with auto trannys. Can't comment on that since I've never driven one, but be sure to let your dealer "hear" it. I think auto trannys in the Mustang are of the learning variety. My guess is the hesitation you feel is some sort of "map" the computer is trying to adjust to. You can do a couple of things to see if they help. First, drive the car hard and see if the tranny "relearns" or re-maps itself. Or, second, disconnect the battery overnight to see if the computer resets itself.

    I have had my 05 mustang 2 weeks, and am currently having the same problem with the gas tank, it was even mentioned at the dealer when the guy returned from filling it up. It is extremely annoying!
  • mcd2mcd2 Posts: 3
    Went to the dealer today and had no problems. The new fuel tank is on order. The hesitation on acceleration from a complete stop was explained by the mech that more than likely my traction control was kicking in to avoid a spinning of the wheels--makes sense. I forgot to mention the Shaker problem though. I'll see if it keeps happening.
  • 68wanabe68wanabe Posts: 1
    Just got my GT and its super. No problems yet. Have a question on break-in period. I know there is no formal break-in period but I'm kind of old school and tend to take it easy the first 1000 miles or flat out accelerations, etc. I've heard from another Mustang guy that with a car like this you should drive it like you will normally so the piston rings will seat properly. If I "baby" it now it will not respond like it really could later on. Any opinions out there on this subject?
  • john_324john_324 Posts: 974
    When I bought my '02, I had the same concern. So I called Ford, and the only thing they could tell me was "follow the owner's manual" (gee...hadn't thought of that... :mad: )

    So I ended up doing that (I think it recommends for the first 1000 miles to drive it normally, but avoid cruising at a steady speed for any length of time). 30,000 miles later, she's doing just fine.
  • graphicguygraphicguy SW OhioPosts: 10,276
    Most people are all over the map regarding break-in. Personally, I think manufacturing techniques and metalurgy have advanced so much over the years, that break-in is kind of passe. That's why I think manufacturers are so vague. But, as they say, no special break-in is really needed.

    While I do subscribe to varrying speeds (and more importantly, RPMs) and subjecting the engine to different load conditions for the first miles, outside of that, drive it like you normally would.

    I'll not take the RPMs past 4K in the first 500 miles. Between 500-1,000 miles I'll run it to redline a few times. Then, past that, It's "katy bar the door". I'll try to keep most of my driving limited to "city" driving (which by it's very natrue varries speed and RPMs). I've made a couple of short runs on the interstate. Will probably gradually increase that after 500 miles.

    More importantly, don't slam on the brakes for those first several hundred miles to give them a chance to "seat" and keep the rotors from warping.

    I've done this routine with all of my cars over the past 10 years. All (save one which was totalled) went well over 100,000 miles with no problems.

    I'm having all the same problems as you except for the gas cut-off & catching again. Just got my 2nd Shaker Cd put in & now none of the buttons light up @ night & the speed control volume doesn't work. Still have the "thunk". Service guy says he hears it, but doesn't know how to fix it. I bet if it wasn't under warranty he'd figure a way. Today was the first time I tanked-up since we bought the car & I noticed the fuel tank problem. I'm afraid next the tires will fall off as I'm cruising down the road. Sorry to say this, but I'm glad someone else out there is having some of the same troubles.

    I drived it like I stoled it from the git go, so far so good.

    The manual just says vary the RPMs. EVERYTHING ELSE is just people's speculations, biases, opinions.

    "Drive it like you stole it" sounded fun and was 100% consistent with manufacturer's directions - so that's what I did.

    I have a GT 5-speed. When backing up and turning I hear a popping sound as if
    the transmission cross member was loose or a rear end linkage bushing was
    missing. Has anyone else heard this?
  • graphicguygraphicguy SW OhioPosts: 10,276
    Don't know the build dates of those of you experiencing problems, but I know around early-mid March builds have the fuel fill-up fix and the "B" series shaker that alleviated the CD skipping problems. For a self test to see if you have the "B" series Shaker, turn your stereo on. Switch it to "AM/FM". Hold down the 3 and 6 numbered keys simultaneously.

    The Shaker will go through a series of "self-tests". At the end of those tests, a number will pop on the Shaker screen. At the end of the series of numbers will be displayed. If the letter "A" is at the end, and you're having skipping problems, the dealer has a TSB to replace it with a "B" series model.

    Speed/volume control of the Shaker has to be programmed. See the owners manual on the procedure.

    I don't have any answers for the "clunking". I'd take it to another dealer's service dept and get their opinion.

    Mine was built on 3/24 and I've had none of these issues. Guess I'm lucky.

    Yes, I have a 05 V6. The front end sounds like a 40 year old car that has bad bushings. And, it makes a ping or snapping sound on occation like a bracket of some sort is snapping back and forth. The dealership drove it and said Ford is aware of the problem and is working on a universal repair that should be announced at the beginning of May. It will require new suspension parts, possible new control arms. They are not announcing the problem for some reason. Probably because not all cars are having the problem.

    I was under the impression that most automotive engines today are turned over by electric motors for a few hours so that the "break-in" period is almost eliminated. The electric motors are used at some point during the assembly of the engines so the piston rings are most likely seated by the time the engine gets to the consumer. However, it is probably still a good idea to avoid using the cruise control for the first 1,000 miles or so. The rings are less likely to take a "set" for a particular rpm.
