This has happened since purchasing my personal 2006 Mustang GT new in 2006. I also see early S-197 Mustangs (2005—2007) in my shop that cannot be reliably refilled because fuel shoots out of the filler neck, splashes the operator, the side of the Mustang, and puddles on the ground. The defective On-board Refueling and Vapor Recovery (ORVR) system causes high internal fuel tank pressures that will also cause the filling station pump to cut off and prevent putting fuel in the tank. This creates a fire hazard as the spillage contacts the left hot tail pipe and muffler as well as a puddle of fuel that can be ignited by a spark, cigarette, etc. This problem is in direct violation of the Environmental Protection Agency emission standards that clearly state the operator is “expected to fill the fuel tank without spit back or spillage during the refueling event.” EPA emission regulations also require that service vents, also known as safety and vacuum relief valves, be installed in tanks to prevent excessive pressure or vacuum that can build up “due to tank filling or emptying.” The parts of the Ford ORVR system that contribute to the fuel tank pressure spikes and fuel spills include: 1.Poor fuel filler design. The filler pipe is narrow (5/8” to 3/4”) with a severe an S-bend before it reaches the tank. There is a spring-loaded plug at the top of tank built into the fill neck that closes the fill pipe until fuel pushes the plug down to open the fuel tank. 2.Poor fuel tank design. The saddle style tank has two sections that “saddle bag” over the drive shaft making the opening between the two tanks very narrow and at the top of the tank. 3.Insufficient tank venting system. The capacity of this vent system is not sufficient to vent the fuel tank during refueling. Please see attached file that documents the problem and possible solutions. I also recommend sharing your many complaints on this problem with the EPA as the problem is also in their area.

Did not sustain some sort of accident in order for me to notice thank God, I simply noticed thanks to multiple virtual methods which told me-considering how stupidly fast this car is and how important air bags are whe combined with that I thought id do this. Ford doesn't really care unless it can somehow bleed more money from something so...kinda just letting y'all know. Not much else I can do..other than drive really carefully (5-speed and I suck with Manual :()
Dealership refuses to do recall
The contact owns a 2006 Ford Mustang. The contact stated while driving approximately 40 MPH, the front end of the vehicle made an abnormal clunking sound and shuddered significantly.

I have a 2006 Ford Mustang GT; 100,000 miles, excellent condition. While driving and when turning, at any speed, the steering wheel locks making it impossible to steer. I took it to two different mechanics who would not work on the problem as they believed it to be a defect, and they did not want the responsibility of the repair required. I then went to the Ford dealership, and the service manager said he had never heard of such a problem. It is very dangerous, and impossible to determine when it will happen again. Therefore it sits in the driveway. I want to keep the car, and don't want to sell it to an unsuspecting person. Please help if you can. Thank you. The owners manual advised and encouraged me to contact the NHTSA.
No a pasado nada están encendidas las luces de advertencia del airbag solo eso
While driving the car goes into limp mode randomly causing the RPM’s to fall. There is no power to get off the road safely and has almost caused an accident numerous times. I have had Diagnostics ran and the mechanic has no clue what’s causing this. Ford forums are full of these mustangs doing this. It is a huge safely risk!!!!
On June 18, 2023, my throttle unexpectedly stuck open after intentional acceleration, causing the car to continue to accelerate uncontrollably after releasing the accelerator pedal. The engine continued to increase RPMs and speed. After using all of my leg strength to apply the brakes to fight the uncontrolled acceleration, the throttle unexpectedly eased up and returned to normal. This was the most frightening instance. On two other occasions, I noticed similar uncontrolled acceleration that seemed to correct itself immediately after shifting, where the tachometer approached 5k RPMs. I have not had the vehicle inspected, and there were no warning lamps, or other symptoms prior to this failure.
I bought a 2006 Mustang convertible for my wife on her 40th birthday. We store the car every winter and bring the battery into the home. Car has 40k miles. 6 years ago we began experiencing amperage draw while the vehicle is off. I have went through 4 batteries, 1 alternator, several flat bed truck tows, and weeks into service at my local Ford dealer - only to have the dealership continue to tell me how difficult it is to find 'parasitic' amp draw because it is intermittent. My wife has had it being stuck and now afraid to drive the car, and contemplating to get rid of it. I work for a major tier 1 automotive supplier in engineering and know how my company pays special attention to NHTSA complaints and investigations relating to our products. I am hopeful that Ford engineering will get a hold of me and get this right before I take the Mustang to the scrap yard!
For nearly a year now I’ve been in touch with Ford and its dealerships to get this recall rectified to no avail. I spoke to corporate Ford customer care on 2/6/23 and was told that the vehicle in question with the recall will not be repaired due to its age! So I responded on a recorded line to make it clear Ford is refusing to repair the recall and is opening its self up for a major law suit. Mind you my teenage son is the primary operator of the vehicle and Ford simply doesn’t care. Please file a violation to the said recall on our behalf ty.
The contact owns a 2006 Ford Mustang. The contact stated the front driver’s side seat belt failed to latch properly. The contact stated no warning light was illuminated. The contact took the vehicle to the local dealer, where it was diagnosed with needing the front driver’s side seat belt latch to be replaced. The vehicle was repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 61,200.
Sudden failure of rear differential bearings
Rear differential bears wore out
I have documented eight separate unsuccessful attempts to repair outstanding recalls on my vehicle due to Ford’s repeated refusal and continued failure to provide a loaner vehicle for the duration of the repair. Whether the required time is half-day or one week it makes no difference, I cannot run my business without a vehicle. Please advise how to proceed. Thanks
Vehicle was involved in a very serious accident which caused injuries and well as scared me away from driving fords….our young child was also in the car….. it is so scary that the air bags did. It work on vehicle at all……..
