  • 92,500 miles


Returning home from work, the engine stopped operating. I pulled onto the median and managed to bring my vehicle to a stop. The check engine light as well as other icons were lit up on the information panel which indicated there was still electrical power. After a couple of attempts the vehicle started and I proceeded on my way. Traffic was heavy by this time. Within the next mile or so the vehicle stalled an additional 4-5 times particularly when stopped at intersections. I managed to restart the vehicle and proceeded directly to the auto dealership since it was on my way.

Our 2005 Ford Mustang V6 started showing no fuel on the gauge approximated in June of 2013. At first it was random but now it never shows gas in the tank even when the tank is full. We keep track of the miles and keep it filled because we have no gauge. As of March 2014 the car has a check engine light on and has started to stop when at intersections. It acts like it has no gas. It is frightening when your car is sitting in busy traffic and won't move. So far it has started up after a few tries. We are very concerned after reading other Mustang owners have the same problem and Ford has done nothing to recall or try to help owners fix this issue.

I own a Ford Mustang 2005 V6. The first thing to happen around December of 2013 was my gas gauge dropped to empty and the low fuel light came on with a message of failure to read the amount of gas of vehicl when in fact I had a full tank. This started doing it every so often and now does it on a daily occurrence, the check engine is on and I have dificulties to pass pollution test in Illinois because of that. This is happening to many Mustang oweners and really sounds like a defect on these Ford Mustang. It is not a cheap fix and Ford needs to step up to the plate and a recall needs to be done. This is a safety hazard that needs to be repaired.[xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Recently purchased 2005 Ford Mustang and was told upon sale that there was a problem with the fuel gauge. I figured it would be easy enough to fix so wasn't really concerned. Now a week later I noticed the speedometer doesn't work as well. It sticks on 15 mph for periods of time or then will show at least 15 - 30 mph faster than I am actually going. I searched online for a fix and found thousands of threads of individuals with the exact same issue and even copies of letters sent to owner stating that there wasn't a recall because it's not a safety concern. I bought this car for my daughter. Running out of gas late at night because her fuel gauge is broken is a safety issue. Sure can she write down mileage every time she gets gas, yes. But after reading so many comments by so many people it seems as if this issue should be resolved by Ford. Seems to be isolated on the 2005 only. In addition not know your speed limit is also a safety concern and also a financial concern should you get pulled over having no idea how fast you are driving. Its seems as if the entire cluster of gauges are faulty and need to be addressed. Your response or help in getting Ford to rectify is greatly appreciated.

Gas gauge erratic. Then failed last August. Ford says must replace entire cluster at cost of $450-650 plus labor this seems to be a common problem on this model. Only 45000 miles on this car. Cost seems excessive. What is Ford doing to back this up? updated 06/10/13

Speedometer, tachometer, temp, and fuel gauges fail intermittently. Gauges get stuck or provide false readings.

The first thing to happen around June of 2011 was my gas gauge dropped to empty and the low fuel light came on when in fact I had a full tank. This started doing it every so often and now does it on a daily occurrence. The next thing approx. A month later my tach started acting strange and is now stuck in one position and has been that way for about 6 months. Starting last September the speedometer would drop down to 0 while driving, sometimes it shows going 20 or 25 miles per hour when in fact I am probably doing 55 or 60. This is very distressing as I love my Mustang and bought it brand new in December 2004. It now has a little over 70000 miles and I am seeing where others have this same problem. This is not a fluke but sounds like a defect on these Mustangs. It is not a cheap fix and Ford needs to step up to the plate and a recall needs to be done. This is a safety hazard that needs to be repaired.

First the gas gauge hand would stay on empty even when filling up or it would go straight down way past the full mark. Never know how much gas I have. Now the speedometer is not working properly. It will either stay at 0mph while I'm driving or say I'm going 20-30mph when the car is shut off and not even running. At times it says I'm going 110mph when I'm driving through town which is a 35mph and clearly I am not driving 110mph. I find this to be a great hazard to other drivers since I never know how fast I'm going. After doing internet research it seems many Mustang owners have this same issue. I feel that having a defective speedometer is a safety hazard that needs to be addressed if safety is really important to the NHTSA.

The fuel gauge began to act erratically before ceasing to work altogether. I took the car to fairway Ford (placentia, ca) and reported the problem. The service writer dismissed me by saying the repair was too costly and that there was no known universal problem with the 2005 V6 Ford Mustang. He did not document the problem reported on my service record. I have a colleague with the same year and model who has the same problem.

Failure of instrument cluster and water leak in passenger side foot well. Speedometer non-functioning, fuel indicator non-functioning, and engine temperature gauge non-functioning. Provides serious safety hazard without knowing vehicle speed. Any substantial rain results in water pooling in passenger side foot area, and saturation of fuse box area, which provides concerns for a vehicle-wide loss of electrical power and brake/steering control. I have looked at several online owners' forums and there are numerous cases of this commonly-documented safety problem, but Ford Motor Company refuses to address it until NHTSA issues a recall. I have called fmc, and they refused to address the issue.

My fuel gauge on vehicle has quit working and says I have no gas when I have just filled up, the speedometer also goes erratic and says I'm going 120 when actually going much slower, the cold hot gauge either reads hot, regardless of if I just started the car or if its been running for an hour.

  • 70,000 miles
Approximately a year ago, the speedometer and fuel gauges on my 2005 Ford Mustang started to malfunction. Since then, they have been giving me false readings. Examples include my fuel level will read at half a tank when I will actually be near empty, the more pressing issue however, is that my speedometer keeps giving me increadibly inaccurate readings, saying I'll be going 90 mph, when I'll really be going 20, or saying that I'm constantly going well over 150mph...even though my car will be parked and turned off. I have read that many other 2005 Mustang owners are having this problem and being told they are having to pay anywhere from $500-600 for the repair when it is clearly Ford motor's fault. I cannot afford to pay this, but I cannot afford to continue having to guess my speed either, it is unsafe, and potentially causing me to break the law by speeding. A recall order needs to be issued to save me and my fellow Mustang owners from having to pay this excessie cost for a problem that is the maker's problem.

  • 28,000 miles
My Ford Mustang has now 32K miles on it purchased new and only one owner/driver. All of my instrument are no longer working or work erratically. I am having problems knowing what speed I am traveling, if there is gas in my car. I am a woman who does not like to get stranded on the highway and this is now a big fear. I cannot tell what my speed is and therefore am very leary driving unless with traffic so I can keep with them. It is apparent alot of others are also complaining about the same problem to the point it starts to cause transmission problems. Is there something we can do to get this up as a recall, what options do we have" I cannot afford to replace all clusters for 600-700 dollars and find out it is still having problems. Any suggestions"

  • 77,000 miles
In 2008 Ford replaced the gas tank on the Ford Mustang because of a defect in the gas tank for refueling. Engine light comes on indicating either low fuel pressure or emitting emissions. Verified problem at perry Ford poway ca with [xxx] explained that the new gas tank needed to have new fuel pump cell to match the new gas tank. Ford customer service verified only new gas tank installed in 2008. Ford wants me to pay for correcting their error of not matching the right fuel pump cell to the new gas tank. If the gas tank is leaking fumes this should be considered a risk to me and other that had a gas tank replaced.

2005 Ford Mustang been to the service department 3 times for not being able to fill gas tank, spews out even at a trickle from the pump 4th time returned to dealer and said there was a repair but now my warranty has run out. They knew the repair was available long ago. Surely this qualifies as a defect in the system. When it happens my wife gets covered in gas shooting out the filler neck.

When attempting to put gas in the vehicle you have to run it in real slow or the pump will shut off. It acts as if the tank is full even though it is almost empty. Apparently the gas is pooling where the end of the pump releases the gas, there is a sharp slightly uphill right angle for the gas to travel and there is not enough room to for it to move through like other cars. The gas float stopped working as well, the gas needle is buried on the far right side of the guage inside the car, it is worthless, I believe these are related because they happened right around the same time.

Gas tank will no longer accept gas from a gas station pump. We have repeated shut offs of the pump. Can only use pump by turning gas pump upside down. This is a public safety issue as gas will overflow the tank and will spray into the ground. Ford is aware of problem as a design defect, but will only cover expense if car is under warranty. This is a problem in 2005 and 2006 Mustangs which are most likely out of warranty. Ford should be required to fix this problem when it occurs.

2005 Mustang V6 automatic. Stalling unexpectly this has happened several times. Repair shop unable to find out what is wrong. Also temperature gauge not working already replaced the sensor and it worked for a while now not working again. Now my transmisstion is slipping. And of course filling the car with gas is also a problem. Seems to be that all these problems are very commong and I think Ford should be taking care of fixing them.
