Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

I own a 2005 Ford Mustang GT rain leaks into the passenger side interior above the fuse and smart junction box. When I was driving it in the rain I lost all electrical functions ie headlights, brake lights wipers, horn and so on. Luckily I was driving during the day and could see had it been night time I would have crashed. I called my Ford dealer and they stated that are aware of the water leaks with the Mustangs but did not offer to fix for a defect on their fault. A search of the internet shows many people with the same problem.

I have a 2005 Ford Mustang. There seems to be a problem with the panel the rpms do not work, the gas gauge doesn't work and the cold to hot gauge does not work. I contacted Ford they said there is not any recalls and it my problem. And I needed to have it fixed thought it seems to be a computer system error with the start the rpms would work then not work. I thought well not big deal might work its self out then I noticed when adding gas the gas gauge would spin around like a clock and you could not read it or know when you were running out of gas that is very unsafe to be on the road with out knowing how much gas is in your car. And the low on gas light does not come on to tell you either. Then what failed was he cold to hot gauge. Nothing works on the panel at this time. I cant drive the car feeling safe.everything seems to be some sort of computer problem with the car and Ford does not want to step up to the plate and say there is a problem with there car but there is and there refusing to fix it like they told me its not there problem. I told them they need to pay for and fix this problem I didn't build the car they did they refused.

I was driving on the 407 traveling 110 km per hour. Windows, radio, fan, lights, emergency lights started to fail. The car was losing speed. It broke down on the highway and emergency lights nothing would work. I called 911 because I was scared of getting hit. Police came and my car was towed to the Ford dealership. They replaced the alternator and battery costing $566. A month later the same thing happened. I find out that this is a common problem with Ford vehicles, a faulty firewall seal causing water damage to the smart junction box. I found many Ford consumers online with the same problem. This is a danger to our highways. Ford is now telling me this will cost $3000 to fix, not only is their manufacturer's defect a danger, it is costing consumers thousands of dollars. They have lied to me saying it is caused by a crack in my window. They are trying to cover up a bad defect.

The contact owns a 2005 Ford Mustang. The contact stated that the instrument panel was inoperable including the fuel, temperature and speedometer gauges. Both the dealer and manufacturer advised the contact to replace the instrument cluster and advised her that there were no recalls associated with the failure. The vehicle was not repaired. The current mileage was 121,000 and the failure mileage was 100,000.

The car's instrument cluster suddenly completely malfunctioned, the "fail-safe" engine system light came on, causing the engine to shut down and to suddenly stop the car in moving traffic. This was truly a life-endangering situation. The speedometer and the engine temperature dials of the instrument cluster had been erratic in the past weeks before the incident. Obviously, this car is unsafe to drive. For more than five weeks Ford Motor Company has claimed to have no instrument clusters available to fix the problem.

Speedometer failure. The speedometer in my car started showing I was going 10mph while the car was not moving.I had to turn the car off and restart it to get a correct reading. Eventually that didn't work. The speedometer would stay at 10 or 20mph till the car warmed up, then it worked fine. Then it started staying at 20mph if the weather was cold. (at night it didn't work, in the daytime when it was warmer outside it worked). Now the speedometer doesn't work at all any more. Its permanantly stuck on 55mph even when the car isn't running. I did research on line and found a large amount of 05 Mustang owners with the same exact problem. This is a safety issue and an obvious manufactured defect and needs to be recalled to fix the problem.

I have an 05 Mustang, automatic, V6 it has about 65,000 miles. I like everyone else am having problems with the gauges and the car stalling for no reason. I noticed no one has been killed yet so I guess that is what Ford is waiting on before doing a recall. This is crazy. Someone should make them take a look at what is happening with this vehicle and issue a recall.

When stopped suddenly the car will remain idle for about 30 seconds before it will kick back into gear. When this happens, car will roll backwards in drive. If you try to press the gas to force the car to move it will stall completely. Car has been doing it since 2007. Ford dealership could not find anything wrong with it. Car currently has 44,000 miles on it. Also gas, temp and speedometer gauges have started going crazy the last three weeks.

While driving in the evening the engine temperature and fuel gauges failed. The temperature gauge gradually kept climbing higher above the red line. An inspection of the engine compartment reveled that the engine was operating at normal temperatures. The fuel gauge also started registering incorrect reading; gradually moving past the full line even though no fuel was added. Starting and stopping the engine caused the fuel gauges and temperature gauges to turn clockwise (or higher). Both gauges currently point down and are effectively useless. The repair shop in researching how to replace or repair the component and how much the part will cost. The failed components appear to be linked to the vehicle's speedometer.

All of my gauges are out..I don't know my speed, temp of my car, etc. Dealership advising the cluster is out & its a common problem. Estimate for repair is about $1200. I see multitudes of complaints for this same reason..same year & make & model. This obviously should be a recall.

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.

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.

The contact owns a 2005 Ford Mustang GT. The contact was driving 40 mph in heavy rain when the entire electrical system failed without warning, including the lights and dashboard gauges. The contact continued to drive with caution to a nearby service station. The engine was turned off and restarted after five minutes. The vehicle resumed normal operation until the failure recurred within twelve miles. The dealer was notified and informed the contact that the failure would be difficult to diagnose since the vehicle was operating properly. The failure mileage was approximately 66,200.

In reference to tsb-08-26-7 and tsb-07-14-6, there is a difficult to diagnose water leak in the floor board of the vehicle. The water leak coming from the passenger side of the vehicle from the wheel well into the floor board of the vehicle comes into contact with the smart junction box (sjb) of the vehicle. When water seeps into the sjb, it short circuits the majority of the electrical system of the vehicle including: Headlights, tail lights, A/C, instrument panel, radio, windshield wipers, rear defroster, windows, door locks, and a variety of other items. If all the correct conditions prevail, such as, night time driving in the rain and the water seeps into the sjb and short circuits it, the driver is left in the dark with no lighting, no wipers, or instrumentation of any type. Quick fix for dangerous condition was to pull the kick panel out of the floor board, unplug the sjb connector, and allow to briefly air dry before reconnecting. Vehicle was taken to dealer only to be claimed the "instrument cluster" was bad. Even though the tsbs were mentioned by the owner, nothing was said of the sjb being the problem.

Water leak in passenger side kick panel Ford knew of water leak issue when vehicle was manufactured. I had about an inch of water on my passenger floorboard after a storm. Also rear brakes stick after using emergency brake. If I ever have to use my E-brake in an emergency the rear wheels will lock up and be even more of a hazard and danger. Both these issues are very safety related. Searching the internet you will find literally hundreds if not thousands of complaints about this water leak and E-brake damage issue. Please do something about this. I am currently thinking of suing Ford for the water leak and the fact that the technician at the dealership admitted this is a known Ford problem but not enough people have complained for them to care...

Took my 05 V6 to the dealer because there was a collection of lights on the dash lit up, check engine, brake, oil pressure, traction control, traction control off, low fuel, fuel gauge not working and the turn signal lights on dash didn't work either. This happened after water leaked into my car after a hard rain. Dealership said smart junction box got wet due to bad sealant, which caused the leak. However, smart junction box is not covered under warranty and my car only has 65K miles. This is now the third time this has happened due to their mistake.

Driving on wet roads, front passenger side leak, shorting fuse box. Car lights, turn signals, instrument panels, and radio all go dead. When car is put into park it will not shift back out. Dries out, and all is well again. This is an extreme safety issue.....imagine if you will driving on a highway late at night in traffic only to have all your lights and turn signals go out.
