Mustang 6-cyl

  • 98,000 miles


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 2005 V6 Mustang gauge cluster is erratic. RPM run high/low and stick. Gas gauge has spun past full and points toward the floor. Temp gauge sits at 3 O'clock most of the time. Speedometer intermittently works fine, reads incorrectly or doesn't work at all.

The contact owns a 2005 Ford Mustang. The contact stated the speedometer failed to function and does not register the correct mph while driving. The speedometer would only display the maximum speed or zero. The dealer stated that the contact would be responsible for paying $100 for a diagnostic test and $600 if the speed cluster needed to be replaced. The repairs were covered by a recall or warranty. The manufacturer stated there were no recalls and offered no assistance. The vehicle was not repaired. The failure mileage was 36,550.

I have a 2005 Ford Mustang with a speedometer failure. Having accessed the internet have found an amazing amount of other folks within the same problem. The failure can lead to problems with the transmission shifting causing unsafe operation of the vehicle. It's unbelievable how many other people have had this problem. When contacting Ford Motor Co. Their response has not been to side-step the issue and not acknowledge the problem. Their rep suggested that a recall would have to come from your Agency. Those of us that have the problem feel that the repair cost($500.-700.) should be Ford's responsibility, not the owners of these vehicles. It's a shame that when something as obvious as this defect is cannot be admitted to be the faulty manufacture of the component by the company that produced it. Makes one reconsider what brand of vehicle one should buy next! please help. I'm sure you've had plenty of complaints about this same issue.

Speedometer works intermittently. Sometimes does not register speed at all. I consider this to be a dangerous situation. This apparently has happened to many 2005 Mustangs. Ford should be required to repair free of charge.

Speedometer on my 2005 Ford Mustang does not work properly. It stuck and does not move. Other owners of 05 Mustang V6 have this same problem as well as malfunctions with other gauges. It is a huge safety issue when gauges don't work properly. This is not an isolated malfunction, as it is problematic in so many 05 Mustangs.

It had rained in the day, but was not raining at the time. Turned the A/C on as the glasses were foggy. Dashboard warning system went off with all kinds of warnings. All electrical components including lights, radio, locks failed while the car was being driven. The engine was running ok. Drove home as it was during the day. Found water in the fuel cutoff switch on drivers side and on the floor on passenger side near the fuse box. Used paper towels to dry both. Did not help. Left the car for an hour or so and then it was working fine. Could have been a major safety issue if it happened at night. Car has been running fine since.

There is a manufacturer's defect that allows water leakage into the instrument panel/smart box junction and subsequently into the vehicle itself. Resultant issues include the inability to drive the vehicle (frozen shift), electrical failure with loss of instruments including various gauges, brake lights, ventilation/ac, power windows, and headlights, and physical water damage (mold/mildew). Ford is aware of the defect and later models were redesigned to compensate for the flaw. However, Ford refuses to issue a recall or acknowledge the deficiency, nor will they provide any kind of financial assistance with the necessary repairs directly caused by this defect. Should the Mustang experience the above mentioned electrical failures while being driven, an accident could occur. There are numerous similar incidents reported about this exact same issue, and Ford must be held accountable. I spoke to Ford "customer service" on 5/5/11 to report the issue and request financial assistance for the repairs. I was told to take my vehicle to the dealership, pay for the diagnostic test, and have the dealership confirm the "defect". I made a follow-up call to Ford "customer service" on 5/9/10 to report that the service manager did confirm the defect and that he had seen similar problems. However, Ford said they were not responsible, would not provide financial assistance, and that I was "misinformed" by my initial call to Ford in giving me hope they could somehow help me. Additionally, they stated that I "should not expect my Ford vehicle to last beyond 100K miles". in the meantime, we are responsible for the towing, diagnostic, and repair bills, so the Ford service department is profiting from this. This was our fourth Ford vehicle, and it will certainly be our last.

2005 Ford Mustang - instrument cluster failure. The speedometer gauge shorted out, heat gauge improper reading, and tach stuck. Concern of an electrical fire. In reading more information, many 2005 Ford Mustangs have this problem that can cost up to $800. Ford should recall.

My 2005 Ford Mustang V6 has been having speedometer malfunctions weekly. These malfunctions cause the speedometer to start at numbers that are not 0, resulting in an inaccurate reading of my speed. It read 120 while I may only be going 40 and even when I shut down the vehicle it will remain at 40+. a temporary fix is to turn the vehicle on and off which sometimes causes the needles to slowly drop, but usually it will stay over 20 for extended periods of time, and when I do succeed in reaching 0 within a week or two the problem will occur again. I have been in contact with many other owners of the same model and year of this vehicle and all are having similar problems, most of us have gone to a Ford dealership and have been told that it will be a $500-$650 repair/ replacement of the instrument cluster which seems to be the reason for the problems, but since so many are having a similar problem shouldn't this be a recall?

  • 75,000 miles
The contact owns a 2005 Ford Mustang. The contact was driving 25 mph when the speedometer malfunctioned. The contact called the manufacturer and the manufacturer took a complaint from the contact but did not provide any assistance regarding the instrument cluster. The dealer advised to bring the vehicle in for diagnostic testing. The vehicle was not repaired. The contact was concerned because he was not aware of what speed he was traveling and believed the manufacturer should be liable for the repairs due to the numerous complaints he discovered online in regards to the failure. The failure mileage was 75,000.
