2005 Ford Mustang GT Problems

If a squeaking noise is heard while turning the steering wheel, the outer tie rod ends may be worn and should be replaced.

4.0L V6 engines may develop a buzzing type noise from the upper engine area at about 1900 RPM, under light acceleration. Our technicians tell us this can be caused by loose ignition coil bracket bolts. Coil bracket bolts should be checked for the correct torque before further diagnoses is performed.

Our technicians tell us the spark plugs in this engine can be very difficult to remove. Ford has issued a service bulletin (08-7-6) to address this issue, which includes a recommended procedure on how to remove the plugs. Failure to follow the recommended procedure can result in the one or more spark plugs breaking off in the cylinder head.

The recommend procedure is as follows. Using this procedure will greatly reduce the chance of breaking a spark plug.

1. Break the spark plugs loose when the engine is warm.
2. Turn each plug 1/8 to 1/4 turn and soak the treads with 1/2 to 3/4 teaspoon of Motorcraft Carburetor Tune-Up Cleaner or a quality penetrating oil. Do not try to remove the plugs at this time.
3. Let the threads soak for at least 15 minutes.
4. After the soak period, tighten and loosen each spark plug, working it back and forth until the turning effort is reduced. Then, you can remove the spark plug.

There are special tools available to remove the broken spark plugs and repair shops will often charge additional labor time, over and above the quoted spark plug replacement cost, for the removal of each broken spark plug.

2005 Ford Mustang GT Reviews

As soon as my car dropped out of warranty it basically fell apart. It's almost as if key components are designed to fail. If this car was brand new it would be replaced under the lemon law, but since it worked perfectly up until the warranty expired, I'm now stuck with a total POS. 27k miles - California owned car. It looks like its in perfect condition but its a perfect piece of poo.

Nothing but problems with throttle body after the warranty was up. Rocking sound system but burned cd's skip to the point that they can't be played at all. Beautiful car but will not buy another one.

I have a 2005 Red mustang GT--bought it brand new in dec. 2004. basically love the car--goes 0-60 in 5.5 seconds. 1st problem, the cd player always skips especially on cd's i burn. very disappointing because the stereo system rocks, 2nd problem, #8 cylinder wiring harness took a crap at 16,000. 3rd problem, "fail safe mode" light comes on, turn engine off and back on and it goes out. but if ...
