Ford Mustang (2005 & newer) Problems and Solutions



  • mschmalmschmal Posts: 1,757
    Since it is fuel vapor that causes the problem, I was wondering if people noticed the pump shutoff to occur more frequently during warmer periods of the day.

    I know that you should try to buy your gas in the morning because during the day if its a hot day, the gas expands and since you are paying for volume, you don't get your money's worth...

    I think the problem also occurs more frequently if you try to add gas to a tank that is already half full or more.

  • I have a 2006 Mustang and have had the fuel fill problem a couple of times. The interesting thing is that it's only been when I go to a Shell station. I have had no problems at Exxon or Lukoil (I think this was previously Mobil). At one of the Shell stations depending on which pump I'm at the fuel pump shuts off prematurely and other times I'm OK. The Ford service manager gave me a similar explanation to yours about the vapors.

    I also think it's important for all of you to note that this is not unique to the Mustang. A couple of weeks ago I was getting my car filled and while there a guy with a brand new Corvette and someone with an SUV (I think it was a Suburban) were also having problems. The station attendant (in NJ we don't have self-serve) tried maneuvering the pump in different angles until those vehicles were filled.

    On a recent service apt. at the dealership I overheard a woman complaining about her Mercury having a similar problem.
  • I do appreciate everyone's input here, it's part of why I posted to begin with. I was told by the Military Car Sales folks about filling at a different time of day and possible problems because the weather is warm. I think our weather has been getting consistently cooler since I bought the car (it is that time of year of course). The next time I fill it I will try in the morning.

    I realize that every car may have this problem at some point, no matter the make or model; my parents have an F-250 (or F-"something" anyway) that has a temperamental second tank. If they don't pump the gas in just perfectly, it locks and then they must wait hours to try to refill, because no amount of moving the nozzle around gets them anywhere. On my own Explorer, I had the pump shut off on me a couple of times, but just backing the nozzle out of the tank a bit fixed the problem immediately, and then I just pumped that way all the time and never had an issue again.

    If I can figure out what the trick is with the Mustang, I guess that's okay, but the impression I'm getting is that it's not consistent in what you have to do to get the Mustang tank to fill, even with each individual car. I absolutely hate things that don't act the same way all the time; either work properly, or have a workaround that's consistently effective, but don't give me the in between stuff, I just don't have time or patience to figure it out every time. I'm like that with computers, too. :)
  • Excuse my anger and my language, but this *&^%$#fg car is gonna get me killed! First was just annoyances, I can't put gas in it, the old vapor lock thing, I have to wait and wait to pull out into busy traffic, the old throttle lag thing, last week, I pulled out into traffic from a side street there was a car coming faster than I thought, so I hit the gas, well it took off like a trooper, then,,,,,,the transmission TOTALLY DISENGAGED.......just UP AND QUIT.....only lasted a few seconds, but geeeeeze a few seconds is all it takes for a semi truck to shove you off a damned cliff!!!!!!!! THENNNNN today pulling off the interstate off ramp, the car just "DIED" for a few seconds....I've never seen anything like simply went totally limp so to speak, then took off so hard it jerked my head back. What if that had happened ON the interstate at 80 mph? I'd be toast! I"ve been reading this forum since I got my car, and I see a lot of you are having similar problems. My dealer is trying to get an address for me to as "high up" in Ford as we can go. Would you all join me in a writing campaign before someone is damaged WAY beyond simple annoyance? I love my car, but it's not worth getting run over for! :surprise:

    You have a Mustang GT?

    When you say died, you mean the engine shut off?

    There is a TSB regarding throttle lag on certain cars after cruising on the highway then comeing to a stop haveing throttle lag.. This is caused by airbubbles forming in the fuel pump and the fix is to replace your fuel pump.

    Someone mentioned that you can recalibrate the electronic throttle also.

    I'm not trying to imply that something is not wrong with your car, I just wouldn't be surprised if there was somethign that someone was missing.

    I would strongly encourage anyone that is failing to get redress at the dealership level to try a different dealer.

    Ask around to find out if there is a dealer in your area with a particularly good service department.

    I've worked for dealers where the sales floor was A+ and the service department was F-.

    If changing out the fuel pump doesnt fix it I would recommend finding a competent tuner to reprogram the computer to eliminate throttle lag. This lag is a well known issue and retuning is one of the ways to be rid of it.

    Regarding fuel filling problem:

    In another forum a member posted instructions on what they did to resolve the problem since changing the tank didnt solve it.

    Maybe your mechanic can do this. And if it works we can bring joy to the world.

    I also am hearing noise in the rear of my 2007 Mustang GT/CS. Mine was a whining noise around 60-65mph. The dealer has now replaced the ring & pinion twice now. However after resetting the pinion depth about 5 times to get pattern correctly the noise is gone but now I have a bad vibration at about 60 mph and also at 75 mph only! They tried to re-index the drive shaft but no luck. I now also here a noise when turning sharply at very low speeds. I was wondering if you had any of these problems I have?

    I got the same problem. THey changed the driveshaft 2 times. It is much better, but it still has a little vibration between 60 and 70 mph. Please update if you have any news.

    Some 2005-2007 Mustang GT vehicles equipped with the 8.8 inch limited slip axle may exhibit a moan/groan noise when making tight low speed turns. This may be more noticeable when the axle is at full operating temperature. The noise may also be confused as originating from the brakes or steering system.

    This is a documented problem and the dealer should replace the limited slip clutch pack. Since your dealer seems to be unaware of this, maybe you should get to a dealer that knows what he/she is doing.

  • What your dealer needs to do is fix your car or find some other dealer to do it. There are technical service bulletins (TSB's) for the hesitation after the highway driving. It is the fuel pump getting a couple of tiny air bubbles in it and causing the hesitation after prolonged driving. Get the dealer service manager to look up the TSB. Pretty much every issues with these first production models have been documented and can be fixed. Find a dealer to do the work for you and that wants your business. Describe to them in technical detail what the car was doing and how you were driving. Concentrate on find the right dealer to fix it because chasing Ford will get you nowhere.

  • Thank you for this link!!! I am taking my car in to the dealer next week I hope, and maybe I can point him to this "repair." It all sounds logical to me, except for the fact that my car is only a month old, so I wonder how that filter could be clogged, but you never know.

    Thanks again, I will let everyone know if there is any joy!
  • Thank you all for your replies and I have great news! I (we, with your help) have outsmarted the service dept. and their "we can't find a thing wrong with your car" attitude. Took it in AGAIN last week with ANOTHER list of things wrong. Tank won't fill, died after coming off the interstate, trunk won't pop open, transmission totally failed (see my first post), etc. Called them the next day, oh yes maam, we've ordered the gas tank replacement. Ok, cool, how about the fuel pump? No we can't find anything wrong with it. Hmmm says I to the nice man,that's funny because I just paid $20 bucks this morning to download Ford's very own TSB's and the one about hesitation after a long cruise is exactly as if I'd wrtten it myself. Do you not have access to these TSB's, I asked the nice man, by now not feeling very nice myself. Oh yes maam, our "techs" look them up, but often they don't really match the problem. Hmmmm, I said, give me your fax number. I faxed him the TSB's, later that afternoon, he called and says, yes we've ordered your fuel pump. THAT'S RIGHT you've ordered my fuel pump! They don't realize that we are not the "in the dark" consumers that we used to be. Do your research! So to make this (my apologies, but I think you will find it worth it) long thread a bit shorter, they did what I told them, lol, AND i'm getting a free oil change in return for the $20 I had to spend diagnosing my OWN car!!!!! My theory is, that the fewer warrantied repairs a dealership makes, they probably get some kind of perk from Ford....AND....these TSB's?...if Ford has to repair enough of them they will be forced to do a recall....and you KNOW they don't want that! So they hope the customer will just lie down and accept that nothing can be done. WELLLLLLLL hehehe, "dey don't know who dey messin' wit here"! lol There have been soooo many problems with my car, they've FINALLY admitted that it just may be a bad car, and the call I got yesterday blew me away! They want to meet Monday to discuss buying it back! LOL, after I told them I'd had the car back one day, the NEW tank STILL won't fill properly, went to one station, it cut off at $10, better than the 4 cents it usually gives me granted, but certainly didn't fill, stopped at another station down the street, oh boy it sure let me fill up AND HOW, when i turned around there was a stream of gas down the side of my car and a puddle on the stereo started messing up, wouldn't accept a cd, skipped on "homemade" ones....well what do you know there is a TSB on that too!... so they know they gotta get a new stereo now, also, it's having cranking issue and won't go into gear quickly, so I guess they figure they'd lose less money buying it back than the total rebuild from the ground up the thing seems to need (and it's pretty obvious by now I AIN'T giving up lol). My dealer is truly a great guy, he's stuck with me and defended me through the whole thing. And the service dept. is very nice, BUT they DO have to answer to Ford, so ya gotta watch em. This sight has been a Godsend for me and I thank you all! In return, for any of you who want to see the TSB's, don't pay for them, email me and I'll scan the one you want for you, hehehe, I was also smart enough to print them ALL out before my one month subscription runs out. You can go to Ford's main website and type in TSB, pick the first suggestion it comes up with, it will take you to Motorcraft and you can see the main title of all the TSB's (41 of them I think!!!!!!!), but you have to pay to see the whole thing. Heck, let's let Ford pay for ALL our repairs with that free oil change they are giving me! And please mention my name when you carry in your little TSB printout, *wink*! Wish me luck Monday, I'll let ya know what happens, either way I WILL win!! :blush:
  • Dear Lady

    Can you tell me if there are TSB's for the 2007 Mustangs? If you can provide me with the titles of the 41 TSB's, I would appreciate that, too. I am interested in buying a new GT. I just want to know what I am buying.
  • lmmlmm Posts: 70
    good for you.

    FYI, there are OTHER forums out there that have the TSB's listed for free. This forum is good for listing problems but other forums provide much more technical information.
  • TSB's are listed on this, the Edmunds site, under maintenance.

    "TSB's are listed on this, the Edmunds site, under maintenance."

    I learn something new everyday. :)

    They're a little difficult to find though (at least they were for me :blush: ). Here's a direct link:
  • Yes they are, but they are the "headings" and "summaries" only. The full TSB shows every part # needed, down to what bolts to loosen.
