2005 Ford Mustang GT Problems

What owners report

Owners of this model year most often report instrument cluster problems — speedometers, tachometers and fuel or temperature gauges that read wrong or quit — and, separately, incomplete Takata airbag inflator recalls with parts unavailable for long stretches. A recurring fuel-fill problem (the pump clicking off and fuel spitting back) and, in wet weather, water collecting on the passenger floor and reaching the fuse/junction box also show up repeatedly in complaints.

   Gauges read wrong or stop working

   • 31 complaints (19%)
   • median 50,000 mi at 6.4 yrs old (28 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $600 (median of 5 quotes)
   • filed 2008–2018

   Complaints describe the speedometer sticking, reading high or low, or showing speed while the car is stopped, and other cluster gauges (tachometer, fuel, oil pressure, temperature) failing in the same pattern. Several owners say the problem appears or worsens in cold weather and can sometimes be reset by restarting the ignition. According to complaints, dealers often treated it as out of warranty and quoted several hundred dollars for cluster replacement, and Ford was said to have no recall for it. Reported from roughly 20,000 to over 100,000 miles, often with the first symptoms in cold weather.

   What to check: Before buying, start the car from cold and watch every gauge at idle and while driving; confirm the speedometer matches a GPS reading and that no needles rest off zero.

   “I have a 2005 Mustang Gt that when temperature drops below 50 my speedometer will stay at different speeds when I am at 0. Sometimes 40 70 when I am stopped. When you turn off key restart car it will usually drop gauge 5 to 10 MPH. I have been reading online of numerous gauge failures on this year model. Sometimes my gas gauge will not work properly.”

   NHTSA complaint #10441188, filed 2011-12, 50,000 miles

   “My speedometer and tachometer stopped working around 45000 miles. I took this to the Ford dealership as there is numerous complaints online about this problem expecting this to be fixed. They said it was uncommon and I was out of warranty and would have to pay for this. This should be a recall by Ford for repair.”

   Air bags

   Takata airbag inflator recall not completed

   • 41 complaints (25%)
   • median 61,000 mi at 11.9 yrs old (15 state mileage)
   • 6 mention a crash, fire or injury
   • filed 2008–2018

   Many complaints are about the passenger frontal inflator recall notice being received but the replacement part not being available, in some cases for a year or more. Owners describe being told by the dealer that parts had not arrived or been authorized, and some report being unable to carry a front passenger or use the car as intended in the meantime. A few complaints describe airbags that did not deploy in a crash or deployed with what owners felt was excessive force. Mostly reported between 2015 and 2018 on cars with roughly 50,000 to 120,000 miles, long after the original sale.

   1 related service bulletin

   What to check: Ask for a recall-status printout by VIN and written confirmation that the inflator recalls are closed; the bulletin covers airbag module quality inspection.

   “Takata airbag - I received a recall notice in march of 2017, it is now december, and when I called the dealer, they are doing nothing, as parts or repairs have not yet been received or authorized. It was in for a previous recall a year earlier for the takata airbags but this is another follow up to replace the whole airbag, not some minor parts as previously.”

   NHTSA complaint #11051686, filed 2017-12, 60,000 miles

   “Takata recall takata is filing for chapter 11. My dealership does not have parts for my car and can't get them because of the chapter 11 , so that means I can't drive my car with a passenger without risking the life of the passenger. The driver side has been replaced.”

   Fuel system

   Fuel pump clicks off and fuel spits back when filling

   Mentioned in 9 of 60 sampled complaints

   Complaints describe the fuel nozzle shutting off almost immediately, needing to trickle fuel in slowly, and fuel spitting back out of the filler. Owners report the tank was sometimes replaced under warranty and that the difficulty returned, and several say they were told this is simply characteristic of the car. Reported at any mileage, including on nearly new cars, and complaints note it is worse in cold weather.

   What to check: Try filling the tank before purchase and see whether the nozzle clicks off early or fuel overflows; ask whether the tank or filler has been replaced.

   “Many of the complaints already filed are mine. The gas tank on my 2005 Mustang Gt will not take fuel, spits back (ruining a good wax job), and is extremely inconvenient to fill in cold weather due to having to spoon feed gasoline into the tank. I started complaining 6 years ago when I purchased the vehicle new, but the dealer and Ford both say it's not a problem - that this is just characteristic of this car. The newer fuel tank was installed, but did not help the situation. …”

   NHTSA complaint #10370434, filed 2010-12, 100 miles

   “Just bought car 1 month ago and there are several technical service bulletins on my 2005 Ford Mustang Gt. All of which my car is experiencing. Hesitation on acceleration , loud knocking noise from under hood at low speed turns , extremely difficult to pump gas , pre-mature automatic shut-off , most of which pose safety issues . I called then 48 hours after buying car to ask can I bring it back to repair which they quoted me 2000.00 for a differential issue on a car that has 17,646 miles. …”

   Electrical system

   Water leak on passenger floor affecting electrics

   Mentioned in 9 of 60 sampled complaints

   Owners report water pooling in the passenger footwell, sometimes after rain, soaking the fuse and junction box area. Complaints link this to electrical faults such as lights, windows, gauges, wipers and door locks cutting out, and in some cases the car stalling or not restarting; some say the dealer cited a service bulletin for the water leak rather than a recall. Often described after rain or a car wash, at mileages spread from about 17,000 to over 90,000.

   What to check: Lift the passenger-side carpet and inspect the fuse/junction box area for water stains, corrosion or dampness, and ask whether the leak has been addressed.

   2 excerpts from owner complaints in NHTSA records

   “Since the car has had around 45000 miles on it I began having intermittent electrical issues. Speedometer, wipers, instrument cluster, brake lights, head lights, and blinkers all stop working while driving. I am forced to shut the ignition off while driving and recycle the key just to get the blinker work and then shut it off again to turn it off! Doors will no longer lock or unlock and cannot pop the trunk using fob. …”

   NHTSA complaint #10586656, filed 2014-05, 94,000 miles

   “My car is a 2005 Mustang Gt with only 20250 miles. I usually keep it in the garage, mainly driving on pleasant weekends. On wednesday the 11th, I was driving in a heavy rain when the car suddenly lost almost all electrical components (I.e. No power to any lights, radio, power windows, door locks etc.). All of the idiot lights came on indicating failure across the board. The traction control was also turned off. When I got it home, I noticed that the passenger side carpet was wet. …”

   Brakes

   Parking brake drags or sticks in cold weather

   • 7 complaints (4%)
   • median 42,000 mi at 7.6 yrs old (5 state mileage, few)
   • filed 2007–2014

   Complaints describe the parking brake staying partly engaged after a cold night, causing sluggish acceleration, a burning smell and hot rear brakes. One owner reports a seized caliper and a cracked, deteriorated parking brake cable boot; another reports the brake cable detaching from the lever. Owners say dealers inspected or repaired only when the fault could be reproduced. Typically reported after freezing overnight temperatures or on cars around 14,000 to 55,000 miles.

   What to check: Park the car overnight with the parking brake set in cold weather and check for drag or heat at the rear wheels afterwards; inspect the cable boots for cracks.

   “I have also had problems with my parking brake freezing on my 2005 Ford Mustang Gt last winter. I took it into the shop after it thawed 3-7-07 - they said no damage was done, but they were out of parts. I took it in later and they said they could not warranty it unless they saw the problem. Now a year later it is stuck in my driveway again - I am missing work because of it. Why has there not been a recall yet???? It is bad engineering, and bad customer service. The service has been performed at joe cooper in midwest city, ok.”

Buying note. Check the instrument cluster carefully and confirm by VIN that the airbag inflator recalls are complete, since parts availability has delayed many cars. Also test a full fuel fill and look for dampness in the passenger footwell, which are the other recurring items owners raise.
