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.

For about 3 years, constant problem with water leaking onto my passenger floor board. I have to put plastic bags outside the windshield underneath the wipers every time it rains. This doesn't keep all the rain from coming in but it helps. I can no longer go through a car wash because it floods the inside of my car. I now have a plastic bucket on the passenger floor board in case it rains while I am driving so the interior doesn't get flooded. There is now a mildew smell in my car. There have been many complaints about this so it is ridiculous that we consumers have to foot the bill for an issue that Ford has known about for a long time. The last time I checked with a dealer a few years ago they said it would cost approx. $800-900 to try to fix; I'm sure some people have an extra grand laying around but I sure don't. Ford needs to issue a recall on this issue!! it is a safety as well as a health hazard, especially if people have small children. I am the second owner of the car and it started at about 70,000 miles.

For a while now I have been experiencing after rain - water flowing through the passenger side firewall and along the passenger side kick board where the smart conjunction box (fuse box) is. I have taken it to a Ford dealer who said he didn't know what I was talking about and would be $95 to start looking in to what the problem is. This past Saturday, I parked my vehicle the key was stuck in the ignition and the car will not shift out of park. After searching online it seems this issue can be directly related to water damage. Water seeping in to the fuse box. I also found online where there are a number of model years that have had this issue. Now I am going to be stuck with a gigantic repair bill for a design flaw that Ford knows about and could of issued a recall for.

PCM module/crash data report says that the throttle position sensor went to 100% with accelerator at 60% and then the throttle stayed wide open until accelerator pedal was released to approx 23% percent. Why is there a 40% difference in the PCM data from accelerator pedal position to the throttle position. At the trial a guy from Ford said this is normal and the throttle is designed this way. My husband is now on his way to prison. Is this true and can anyone help or advise us.

In city traffic at a stop light, went to step on the gas to accelerate, the engine started extreme shaking & the car would not go. Shut off the engine & restarted it. The wrench light & check engine light came on the dashboard and car went into limp mode & lost all acceleration. After multiple attempts at restarting, the car was not drivable. Had the car towed to the dealership, advised service rep of consumer satisfaction program 13N03 & was informed that Ford will not honor the program for 2006 Mustang.

Around one month after I bought the car intermittently the I would encounter surges when starting to go at lights or parking the car, coming to a stop... now the car is stalling same as the surges... I have replaced many parts trying to resolve the issue. Now it has become a serious hazard to drive and costly!

The contact owns a 2006 Ford Mustang. The contact stated that during inclement weather, water leaked into the vehicle from behind the glove compartment. On one occasion, while driving 55 mph, all the electrical components failed. In addition, the contact stated that the battery would get wet causing the vehicle to fail to start. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 150,000. Updated 2/9/15

As of today my 2006 Mustang has 58,953 miles on it and it is on it's third alternator. The first one failed at around the 56,000 mile mark and was replaced. My friend and I had traveled about 60 miles N from sacramento to an area between alta and dutch flats and I had turned off the ac and put the windows down. I heard a strange crackling sound and I pulled over about a half a mile afterwards and shut off the engine, we smelled something burning and lifted up the hood. And that was the end of the 2nd alternator it had lasted about 1600 miles. The sparks that were shooting out of the alternator looked like a 4th of July sparkler, and we're stranded in the middle of nowhere. And I'm on the 3rd alternator with less than 59000 miles. Two months later maybe 600 more miles and water from the split in the wiper cowling runs into the car which went unnoticed for several days. I had standing water in the front passenger floor board and some in the rear as well. My repair estimate of almost $600, plus a rental car and not including pulling the carpet and heating the floorboard as rust prevention. My feeling is it's not over yet as I have read a lot of the other complaints from people with the same issue. I have noticed the engine has started to crank like it might not start. Ford posts record profits all the while refusing to acknowledge the financial hardship to loyal consumers who just wanted to own their pretty Mustang, and paid well for it. We are real, we have lives that are affected by this in real and meaningful us! listen to us, for every person that found their way to this web site and posted their complaint their are hundreds out there with the same problems who aren't even aware of this process. We haven't gone out and caused this damage to our cars, we are not at fault and we deserve remediation. Please help.

My car idles uncontrollable and jerks whenever it is driven. If I stop or drive at slow speeds it will just stop running on its own. I simply restart it and it will go, but it will keep jerking and idling.

When someone finally dies from this incident which has been reported numerous times by consumers both on this site and with tsb's from Ford issued as early as 2007 then someone will take notice just like what just happened at GM. Please do something before someone dies. There are multiple electrical failures due to a serious water leak affecting the entire car. My 2006 Ford Mustang has been at the dealership since Feb. 8 2014 and we just picked it up for this issue which was supposedly fixed once before. Now with another fee of $1,200 paid we picked up our car after 2 months and upon driving the car home the ac is not working and the sensor lights are on for the door!!! what does it take for someone to realize there is a major problem here? this comes after an extensive water leak that caused serious mold damage inside the car along with electrical issues, one of which a new battery was needed. This was first "repaired" in 5/2013 but was not repaired because in 12/2013 there was a massive interior flood which lead to a massive interior mold problem and the car also would not start and was towed to two separate dealerships. No one wants to assume responsibility and there is a huge amount of data out there supporting the fact that Ford has known about this issue as early as 2007. The manager at the Ford dealership told us that although he would assume no responsibility for the car because Ford has not issued a recall he would not let his wife or children drive in that car!!

2006 Ford Mustang. Consumer writes in regards to vehicle broke down and computer recall issues. The consumer was informed a new computer was needed for the vehicle, and Ford had recalled it due to a known issue. However, the part was on back order. After 2 months of not having her vehicle, the part was still on back order. Ford informed the consumer, to have the vehicle towed to a Ford dealership. The part neeed was an ECU, the main computer.

Water first noticed leaking inside the vehicle on 5/2013 and was -tsb performed on seals at cowl panel. Car leak was not fixed and started leaking again at same sight, this time with extensive mold spore damage which can be a significant health risk. This car has had multiple(at least 5 times)check engine light coming on, several times the car has just stalled while driving and so far 2 batteries and 2 alternators have been put in to this car and it makes you wonder if water has been leaking since purchase into the electrical system of this car. This has been a known problem at Ford since 2007 but a recall was never issued. I am not sure what it takes to issue a recall but I would hate it to be a respiratory illness or a crash that would bring it to this.

2006 Ford Mustang-car brought into dealership on 5/2013 with C/O water leaking on passenger floor board. This was supposedly fixed.check car engine light was on for the fifth time and this time they replaced the alternator for the second time. Car now(2/14) would not start and the interior of the car is full of mold spores! I have read the forums on line and it is well documented that Ford has known about this leak since 2007 and never recalled this because it was not a "safety" issue however I think it is a huge safety issue when there is water leaking on the inside of the car, the windshield on the inside looks like it is raining and the car has had multiple electrical issues several of which the car has stopped working while driving on the interstate. Now on top of this we have a major health issue and the dealer does not want to take responsibility for this.

Water leak issue coming from the windshield and cowl area leaking into the passenger side compartment shorting out the smart junction box causing the gauges and all electrical to go haywire such as the headlight to go out while driving and the traction control to turn off as well as the windows and power locks to quit working and could cause an electrical fire inside the care if gone un noticed. I have the vehicle in the shop and this is going to cost me $600 or more due to Ford knowing of an issue they will not own up to fix to ensure safety.

2006 Ford Mustang has a windshield vent leak problem, the problem is that the windshield rain vent becomes clogged and drips water into the passengers side kick panel were there is a computer control box the connection become corroded and causes electrical problems. Ford is aware of the problem but refuses to issue a recall to correct the problem. This is a safety issues as it one could cause a fire, two could cause the car to loose power and therefore controlled braking or steering, simply replacing the parts dose nothing to prevent the safety issue. I am told this is a problem with the 2005, 2006, and 2007 Mustangs.

This is really unbelievable [and yes this is yet another leak thread]. I have been hawking the entire leak issue, and a member here in a recent post has identified the smoking gun - clear proof that Ford is hiding a known leak problem with a band-aid. Many have asked and wondered why a piece of white foam exists over the electrical box (sjb) within their passenger compartment side kick panel. Well, in response to one of the threads here, one of our members has now posted this: "... in Ford's factory service manual under the section on replacing the electrical box...(sjb)... inside the passenger side kick panel, Ford refers to the foam sheet over the sjb as a "watershield" and cautions not to remove it when installing the new box..." if this is true, and it should be verified by someone with access to the manuals [which I do not have], here are the facts: Ford designs and builds a vehicle with an electrical box (sjb) located inside the passenger cabin of the vehicle. In fact, the sjb is nestled between the outer fender and the interior kick panel. But for some reason - clearly known to Ford - they find the need to include a foam "watershield" to protect the sjb from water infiltration. Certainly this is [xxx] product quality at its finest, but it would seem that it is far more. It would appear that it is proof positive for those with the problem to demand that the National Highway Traffic Safety Administration (NHTSA) force a recall of the vehicle if only enoughowners notified NHTSA accordingly [another topic/strategy discussed on these forums]. it's black and white. The SN197 leaks, and Ford has know about it for a long time, and has yet to take appropriate action. And no; a tsb does not qualify. The manufacturer is responsible for fixing the vehicle. Writing a checklist - to be used only when a owner complains about the problem - is not the same as fixing the problem.

1. trunk too high; back windows slope blind driver from street light reflection. 2. hood and windshield designed deny driver from seeing the curves coming on side angles. (causing vehicle ending up on curve) 3. ABS auto activate when vehicle going over pothole, causing slipping and driver cannot control the braking distance. 4. ac/heat fan auto activate without consent even when sitting on off. I have a V6, 2006 Mustang. The safety issue that I have is the fact that the design of the vehicle that jeopardizing the children under 3 feet tall.: their trunk are too high and the slanted mirror block visibility. At night time backing out is very hard and there are many blind spots. I have backed up into another car already due to the poor visibility and light reflection: Back window design with an angle that blind drivers when night light hits. The owner and I settled in cash. The front hood of the vehicle center line formed an upside down V-shape whereas it highest peak is in the middle and at night time driving it has limited my viewing ability: Ended up on two curve, because the ceiling height were too low.
