There's a chronic hesitation when you push the accelerator from a yield/merge type situation at low-speed. It's not every time but many times. Today I was going around a car that was sitting in the road with it's flashers on (ie double parked) and there was a car in the other lane on the 2-lane one-way street and I stepped on the peddle to accelerate slightly and it totally choked and I thought I was going to get hit in the rear and then it kicked in. I noted this way back when I bought it and at that time I thought it had something to do with the gearing which it still could. I told service about the issue and I even took them for a drive but of course that time it didn't happen. I've tried over years to id the problem more but while I can see somewhat of a pattern it's not guaranteed. …
Hesitation in gas pedal/throttle body. When pulling out from a stop the car will not take the gas until the gas pedal is down to about half throttle at which time it will lunge and I must let off the gas pedal only to repeat the process until the speed reaches about 30 MPH. Very dangerous. This is a very common problem with this model, 2005-2014 Ford Mustang. I have three of these and they all have the same problem and the previous owners say the problem has been there since the mileage was pretty low. How many must die or be injured before someone forces a recall for repairs on these vehicles?
This has happened multiple times, yesterday being the most recent. While driving down the highway, the car will drop into limp home mode and the check engine light will come on. It is the exact same problem described in Ford's consumer satisfaction program 13n03. They will not cover the Mustang, as it was not part of the program. It should have been.
The engine on my 2007 Ford Mustang was revving high when I started the vehicle. When I put it into drive, the vehicle took off on me hitting another vehicle and crashing through a wall across from the spot I was parked in. This unintended acceleration has not happened prior to this incident but the vehicle only had 5,075 miles on it.
When trying to pump gas, the sensor cuts the flow of gas off at about one half gallon. If you remove the nozzle, gas splashes back and all over the person pumping, the car and the ground. When you continue to pump, the sensor cuts off every second. There is no way the tank can be filled in its entirety. I have had the gas set up rebuilt by my local mechanic, thinking something might be blocking the connection of gas entry to tank, but there was nothing and the problem was not resolved. I was then informed that this is common, that I must find a gas station that has a specific pump with no sensor (not a single station anywhere near my residence), I have to tilt the pump at a 90 degree angle. Well, I tried all of the suggestions, yet my car is still splashing gas, etc. This is a hazard! Not only spilling gas on the ground and vehicle, but myself!! …
Both issues I have had with my car numerous times. The engine light has never come on and through research, I guess it has happened to many others. When in traffic moving slowly, warm temperature, my car stalls for no apparent reason. Today, it did while turning left at a corner. I almost got hit. I have to immediately shift to neutral and restart the car. It happens during rush hour so I end up making other drivers angry which is dangerous. The other ongoing issue I have is the car accelerating by itself. This has been happening for years and has got increasingly worse. I now have other witness' people who have driven the car and had it happen. At midas where I get my car repaired, they drove it and couldn't figure out the issue but definitely scared him. The mechanic thought it is computer related. They tried to find a fix online but couldn't. …
I have a 2007 Ford Mustang 4.0 v6 with approximately 42K miles. It has recently developed a very serious safety-related defect which the Ford dealership has refused to investigate. For no apparent reason, while stopped in traffic and with my foot firmly on the break pedal,, the engine will suddenly go full throttle. This forces the car to suddenly lunge forward as the rear tires start spinning, overriding the front breaks. This has caused me to come dangerously close to colliding with the vehicle in front of me or entering an intersection into oncoming traffic. The only recourse is to quickly turn off the ignition which seems to reset the problem. This happens with some regularity, approximately 2 to 3 times a day but is not reproducible on demand. The Ford dealership has offered to investigate, at my expense, but with no assurance that this problem would be corrected. …
Ford shelby gt500 2007, accelerator stuck! While going around some cars on a 4 lane highway at first I didn't bother to downshift and depressed the gas pedal to the floor. When I realized I needed to downshift and took my foot off the gas while depressing the clutch the RPM's went up and I immediately knew the gas pedal was stuck down. It felt like it snapped or locked down. Luckily I was able to keep control of the car by holding the clutch down and tapping (more like stomping) the gas pedal till it released. I feel fortunate that the shelby has a governor than keeps the RPM's under 6,000. My prior experience with older cars in my teens with sticky accelerator cables was also a life saver. I show this car and floor mats are a non issue removed while driving to preserve them. After I got home I was unable to duplicate with car safely turned off. Will contact Ford dealer tomorrow.
I purchased my 2007 Ford Mustang gt in August of 2007. It was a floor model that the dealer had done modifications to. On 24 jan 08 I went to fill "top-off" the fuel which was below 3/4 of tank. After only getting about 1.87 gallons in, the pump clicked off. I tried to pump more gas into the tank and was surprised when it started to overflow. (after starting the car back up, the fuel gauge was still in the same spot before I started fueling) I also noticed that in the recent weeks my "passenger airbag light" does not read it is in the "off" position when no passenger is present, even though it did read this before. I have since contacted my dealership and am bringing the car in to have them check these problems as well as others I am concerned with after reading the forums.
Tl contact owns a 2007 Ford Mustang. The contact stated that he could only pump six gallons of gas into the vehicle. The pump handle suddenly stopped pumping gas and there was no overflow, warning indicators, or noises. The fuel gauge indicated that the fuel tank was half full. The vehicle was taken to a dealer and they stated that there was a technical service bulletin for the 2005 model that was related to NHTSA campaign id number 10014651 (fuel system, other). The dealer could not repair the failure and stated that the gas tank had two parts and was not transferring the gas to the second tank. No repairs were made. The current mileage was 3,065 and failure mileage was 2,500. Updated 3/4/08
