My 16 yr old son was driving and the speed gauge started reading 90 then 60 then 100 also the temp gauge went into the red. He panicked that car was going to blow up and pulled off the highway at night to call to see what he should do. I find this to be very unsafe in both aspects of not knowing if the car could of caused an accident and also the fact of him being on the side of the highway at night. I have read of others having this same problem, this differently needs to be addressed before a major accident does happen. Ford should be ashamed of this and offer a correction on this problem.

My son was driving his 2005 Ford Mustang yesterday when it burst into flames. He was pulling onto I 95 when the car suddenly shut off. He couldn't even make if off the driving area when it came to a complete stop. Once it stopped black smoke started pouring out. He jumped out of the car and ran away from it when it burst into flames. The car was in perfect condition. Never even missed an oil change. No warning signs of any issues. I am thankful that my son is safe but very upset at the Ford car and have now read many Ford fire issues that Ford has not corrected.

The car's instrument cluster suddenly completely malfunctioned, the "fail-safe" engine system light came on, causing the engine to shut down and to suddenly stop the car in moving traffic. This was truly a life-endangering situation. The speedometer and the engine temperature dials of the instrument cluster had been erratic in the past weeks before the incident. Obviously, this car is unsafe to drive. For more than five weeks Ford Motor Company has claimed to have no instrument clusters available to fix the problem.

I am the owner of a 2005 Mustang. I have already had to replace the throttle body as my car (which is an automatic) would randomly stall out at lights. One time leaving me stranded in the intersection. It is very difficult to fill my gas tank as the gas pump nozzle kicks back for some reason while pumping. My speedometer will read inaccurately at times, sometimes reading extremely high numbers, sometimes not at all. I am using gps and my own discrection when gauging how fast I'm going. After a heavy rainstorm, when making left turns, my passenger floor becomes flooded by water pouring out from under the passenger side dashboard. My passengers feet get soaked as well as carpet, floormat and any other things I have in the floor board.

Lost power steering when belt came off. The harmonic balancer separated with the pulley part moving 1 1/2" toward the motor taking it out of alignment with the rest of the belt.

Lost power steering when belt came off. The harmonic balancer separated with the pulley part moving 1 1/2" toward the motor taking it out of alignment with the rest of the belt. Ford admitted this has been an ongoing problem with the harmonic balancers and there is a nationwide back order on them.

While driving my 2005 Ford Mustang (V6 with 7,000 on the odometer) at approx. 40mph the gas pedal suddenly became totally inoperative. This occurred only once but was followed in two subsequent events with the check engine light coming on and the (yellow wrench light) for the throttle control. This then activated the "limp home" mode. Obviously loosing all gas pedal response while driving was the frightening part of all this.

The contact owns a 2005 Ford Mustang. While backing the vehicle up she noticed a banging noise coming from the front of the vehicle. She exited the vehicle to look for a failure but did not notice any so she proceeded to her destination; however, noise became louder. When the contact reached her destination she discovered that the crank shaft pulley was laying in the frame of the vehicle. The vehicle was taken to a local repair facility and a mechanic stated that the serpentine belt was damaged and was no longer on the pulley. The vehicle is being repaired at a cost of $700. The contact is in the process of notifying the manufacturer. The failure and current mileage was 74,000.

On Saturday April 18, 2009 my daughter called to say that her car was hard to steer. She pulled over and her main belt had come off, which in turn caused the car to overheat. Upon further investigation and turning the ignition over, the belt fell off again and so did the pulley on the harmonic balancer. We had to have the car towed to a shop. Upon arriving at the shop I was told that the harmonic balancer broke off the crank shaft. When the new part arrived you could clearly see that it has been redesigned. We paid $600 to have the necessary repairs done. I was told by our mechanic that he has never seen anything like this and there should be a recall on it. I hope this will make that happen.

The consumer stated when pulling into a parking lot at a very low speed the vehicle suddenly accelerated when brake pressure was applied. The vehicle slowed then quickly surged forward. He placed the vehicle into neutral and turned the engine off. He took the vehicle to the dealer, who inspected the vehicle. The diagnostic test did not show any codes. They could not duplicate the problem. The dealer insisted there was nothing wrong with the vehicle. No repairs have been made at this time. Updated 12/07/05.

Purchased vehicle on April 27, 2005, and the engine blew out on August 12, 2005. There was a ticking noise, stopped vehicle, and checked the oil, put oil in it, kept ticking, and the engine blew out. The safety lights on the dashboard did not come on. Contacted dealer, they hooked vehicle to the machine. They said water got into the air intake valve. Called another Ford dealer to get second opinion, they said that was impossible and it was hydro locked. It should be covered under warranty.

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.
