The car in front of me came to the stop and so did I but as I hit my brake something blew up in my face and made me put my arms up and I lost visibility. The weird part is they went off at a rolling stop under 3 MPH .also last week my car brake switch almost started an electrical fire.

I have written to Ford concerning a fuel leak on my 2000 Mustang. I was advised to take it to my dealer to diagnose the problem. The service technician informed me that the fuel filler neck was rusted out and had a hole in it due to the placement of a shield on the tube. The shield held in dirt and water which allowed it to rust. It will cost approximately $431.35 to repair. This problem was caused by a design flaw by Ford. It is extremely dangerous. I cannot put gas in my car when my children are in it for fear that it will catch on fire. The gas just pours out onto the pavement. Ford needs to issue a recall on this immediately. I should not have to pay for Ford?s mistake. I have a copy of the invoice as well as the repair quote from ramey Ford in johnson city,tn. I will fax it to you if you wish. Ford has sent me an email stating that not all complaints get investigated. …
My gas tank began leaking fuel before I drove it in the first part of 2011. Not only was the grommet corroded but the filler pipe was leaking. I was unaware of the leak in the pipe because of the plastic tube around it and was LED to believe it was either just the grommet or the tank itself. I got the grommet replaced and then through process of elimination found that the pipe needs replacing as well. The replacement process was so easy because so many people have had the same issue with mustangs from '99-'04. This is a dangerous defect because the gas leak can cause gas vapors to get trapped underneath the car and ignite easily. Gas vapors are light but still heavy enough to where they will not disperse completely from underneath the car. Gas also evaporates very quickly so this could happen in the short amount of time it takes to fuel your car. …
I went to fill up my gas tank and after 12 gallons smelled gas everywhere and noticed gas racing out from under my car. There had to be atleast half a gallon surrounding my shoes and if there had been a spark I would have been burned to death. After researching this problem on the internet I found out that hundreds of other people that own mustangs between the years of 1999 and 2004 have all had the same problem with what Ford calls a defective gas nozzle grommet. Not something the 1999-2004 Mustang is a stranger too. I remember the 1974 pinto and I owned one I really am uncomfortable with the thought that my Mustang is even more prone to explosions then my old pinto. Please pay attention to this matter before it becomes the next 1974 pinto. …
I went to fill up my car (gas) and I smelled more gas than what I would consider normal. I looked on the ground under the car and there was a pool of gas, and it was leaking as I was filling. I stopped filling the tank and asked the attendant for something to clean up the gas. When I got the car home, I looked underneath and upon close inspection found the filler neck was where the problem was. There is a piece of plastic surrounding the filler neck, which holds moisture and rusts the metal filler neck. This is the same problem I had with another car I owned!!! Same year. I asked several people I know who own mustangs, and each and every one of them had to have the same part replaced!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! If you search online, there are tons of articles and complaints about mustangs from 99-2004 with the same problem.! This is so dangerous, how come this hasn't been recalled?
On 8/27/2001 I took our car to our Ford dealer due to it feeling lit it was running out of gas even thought it had gas. They could not find anything wrong. On 09/02/2001 while driving to california we had the same problem. Due to it being a holiday weekend it could not be looked at until 09/04/2001. Future Ford of roseville calif. Had to replace the fuel tank sender, cluster asy. Sndr & pump asy. And filter asy. On our way home from a trip to ca. On 05/30/02 we had the same problem again, this time while on hwy 50 in utah. The car bucked and acted like it was out of gas. It stalled resulting in no power for steering or braking. While trying to steer the car to the side of the road on a curve, it went across the road in front of oncoming cars, almost resulting in a accident. ***dimsii ivoq entry posted after 12/12/02 cut-over to artemis****762652
So I thought I had a simple thermostat issue. Went to change the thermostat and noticed the manifold housing (plastic) had a nice crack in it. When doing research on this, I noticed there have been numerous complaints/instances of this happening to other people. Now I am in the process of finding a new intake manifold and will have to pay to have it installed. This seems to be an issue that the department of transportation should be involved in. Poor manufacture design with numerous incidents of failure that result in unnecessary high repair costs placed on the consumer. I am the original owner of this vehicle and think it is ridiculous!
Fuel filler neck leaks. This occurs directly over the hot exhaust pipe of the vehicle. The gasoline drips directly on the exhaust pipe under the bend. And next to the gas tank. This is a very dangerous situation as I had a long way to go home and didn't have any water to wash the hot pipes of fuel. The gas continued to drip on the pipe most of the way home. My kids could have been in the back seat if the car caught fire. I have read that this is a common problem on 2000 mustangs. This should be a recalled problem.
Tl* the contact owns a 2000 Ford Mustang gt. The contact stated that the fuel tube net is rusting out on the vehicle. The contact stated that because of the failure, fuel spills out of the gas tank whenever it is filled. The dealer had not inspected the vehicle, but stated that the tanks are on back order because of the high number of failures. The failure mileage was 82000 and the current mileage was 83000.
