problem #6

Mustang 6-cyl

  • Manual transmission
  • miles


2005 Ford Mustang accelerates on its own. Consumer states that the vehicle will accelerate on its own. He states that the RPM's would be up to 1500. He states that since then, now it accelerates up to 2500 RPM's. a flight recorder was installed in the vehicle. The flight recorder captured the problem the consumer was referring to. The flight recorder was then sent to Ford engineering and they stated the computer was demanding the vehicle to accelerate. The consumer also stated the transmission did not shift smoothly. The transmission would clunk when the clutch was let out, especially in lower gears.

Transmission stuck in neutral four times within the first six months. It happens when you are going slow and you shift into 1st gear and don't let the clutch out and you try to bring it back into 2nd gear. The 3 times it did this in parking lots it was not a scary problem but when it did this at a busy intersection I almost got rear ended. At first Ford could not make it stick while testing and didn't know why it was doing this. Now they are saying when it does stick you either have to come to a dead stop( which I figured out myself) or double clutch it. I haven't double clutched a car since way back in the 60S. They say it has to do with the sensors not working at slow speeds. And they say there is no repair because it is a normal operating characteristic of this transmission. By the way this is the 2nd transmission put in this car. I hope you can help other people with this info before someone has a serious wreck. Thanks.

(1 and 2) the manual transmission on the vehicle has intermittent problems where it will not go into gear (up-shifting). Regardless of type of driving (fuel efficient, hard driving), the vehicle will lock out of the next gear. For example, from first to 2nd gear. The transmission will go approximately half-way into gear and stop. The result is an inability to continue accelerating. The vehicle must be taken out of the locked gear, put in neutral, clutch released and re-engaged, then shifted back into the previously attempted gear (2nd gear in the current example). Possible results of this incident include accidents and injury. I have almost been rear-ended several times. (3) the vehicle has been taken into service twice for the issue. The first time (June '05), the dealership adjusted the linkage resulting in no change. The dealership also told the consumer (me) to make sure the clutch was completely engaged. The second time (10/18/2005) the vehicle was put in for repair, the dealerships service advisor and service manager informed the consumer that it was a design flaw in the transmission. Ford is "looking into it, but there is no solution available at this time and may not be available in the future.

Initial problems: 1. pin strip on driver side was peeling off 2. A/C vent fell out of console 3. convertible top got stuck in the down position. Stopped by closest dealer because I was on vacation and we pulled the top back up. Brought it to a local dealer for repairs and they said it was not covered under warranty because the entire convertible top frame was twisted. They stated this was because I most likely had driven while the top was half way up/down. After several weeks Ford engineers decided to cover the repairs for the top. Took the dealer five weeks to get all parts and replace the top. 4. gas tank replaced because gas pumps would constantly cut off while refueling. 5. A/C makes popping noise every once in while. Current issues: 1. noise in front end while turning at slow speeds 2. after car warms to driving temperature, there is a thumping noise heard in engine, very prominent in interior 3. driver side exterior door handle sticks in the out position 4. convertible top making a thud noise when raising and lowering top 5. exhaust is making a popping noise when if engine is revved right after starting the car 6. slight vibration/rattling noise coming from console while car idles 7. A/C making popping noise every once in while.
