Speedometer at times sticks or shows the incorrect speed. Even sitting idle the speedometer will show 5 miles an hour or even 20 mph. It's extremely inconsistent, so determining the correct speed is difficult to do. The speed will display both, higher than actual speed and lower than actual speed without ryhme or reason. Additionally the needle moves in a sporadic behavior, like a second hand tic on a clock, rather than a smooth consistent flow. The tachometer appears to also be affected although it's much less noticeable.

My complaint is on my 2005 Ford Mustang. The speedometer and RPM went out a few years ago when it had approximately 40,000 miles when the warranty expired. At looking online there are many complaints on the same vehicle same problem. I called gene messer Ford and they said it would cost $99 just to diagnose problem. Apparently it appears that the clusters on these vehicles were not made to last. It is not safe to drive without not knowing your speed. My vehicle begin with the speedometer and RPM jumping around and not displaying right speed and then just stop working! we have replaced the transmission speed sensor and it is still not working. The fuses and relays are fine. So it has to be a bad cluster!

I am the owner of a 2005 Mustang. I have already had to replace the throttle body as my car (which is an automatic) would randomly stall out at lights. One time leaving me stranded in the intersection. It is very difficult to fill my gas tank as the gas pump nozzle kicks back for some reason while pumping. My speedometer will read inaccurately at times, sometimes reading extremely high numbers, sometimes not at all. I am using gps and my own discrection when gauging how fast I'm going. After a heavy rainstorm, when making left turns, my passenger floor becomes flooded by water pouring out from under the passenger side dashboard. My passengers feet get soaked as well as carpet, floormat and any other things I have in the floor board.

On September 1, 2010, the gas gauge on the vehicle failed - reading more than full, and other various irregular readings. Repaired for $75, then failed again next day. Have not repaired again as dealer estimates cost at $1500 due to multiple failures according to their tests. Gas light still works when fuel is very low. On November 1, 2010, the speedometer failed - reading 80 mph when vehicle is stopped. Have not repaired, using gps to estimate speed. I contacted Ford about these issues as they seem very common with this model & year vehicle by a quick search online. They advised that I should just get it fixed at the closest dealership. Given the frequency of this failure I feel they should be responsible as the original parts must be faulty given the number of people posting the same issues online. Ford advised that your Agency was the only one that could order a recall. I would think that knowing how much gas you have or knowing how fast you are going are valid safety issues that Ford should be required to fix at their expense.

Three times in the last 3 years, my daughter's Mustang experienced uncontrolled acceleration. The engine raced without pushing on the accelerator. The brake was useless. Twice she was in traffic and narrowly avoided a crash. This week my wife was using the car and it did the same thing, and she crashed into a building. She was backing out of a parking space when it happened, hitting a pole. Then, when placed in drive, the car raced forward. Again the brake was ineffective. Two years ago, this was reported to a Ford dealer, who didn't find, nor fix, anything. Strangely, they now have no record of the problem being reported. However, Ford does.

I was driving 30-35 miles on a busy street (over pass) in a 2005 Ford Mustang with my wife. The car went crazy unintended sudden acceleration with a frightening noise. I tried desperately to stop the car by braking hard and meantime to avoid the cars ahead and opposite coming cars. The car would not stop. I applied hand brake, that did not help either only to leave heavy skid mark and the car to spin once thankfully in a corner of a three way road, at that stage I tried to put the car in park position, but the second the gear reached the reverse mark the car went full speed backwards crossing the busy nordhoff way hitting a pole and fire pump and with car tires spinning at full speed at the moment I managed to put the car in park position and turn off the engine. Luckily nothing serious happened to me and my wife and no car or other person.thanks to god. How.? I don't know, someone up there must have taken care of us and the others because this street is near a shopping mall and the day was Saturday 15 April and tim was 1 pm afternoon. The police and fire team got there immediately and there is a police report of the incident. I have hard time to convince insurance allstate and Ford dealers to assign an engineer to look into the matter. I need your advise please. W E are emotionally disturbed.

I was driving through a shopping center parking lot at a speed of approximately 5-10 mph, approaching a stop sign. There were about three cars ahead of me. As I applied the brakes, the engine suddenly revved and bucked 3 times right into the back of the vehicle in front of me. The brakes were applied throughout, but did not stop the vehicle. That Monday vehicle was taken to Ford dealership and they could not duplicate problem, therefore no assessment was made. They suggested the after market floor mat I was using could have possibly been the cause for the sudden acceleration. I disagree, the floor mat was very heavy and did not shift about and was not in the way of the accelerator pedal; although, I have removed the floor mat. Any further incidents will be reported.
