Im having a hard time with my car to get it started. It takes about a minute to start it. I took it to autozone to get it checked and they gave me the report issue the report shows: p0607 control module performance. Also I been having to refill coolant box more often I bealeive it has a leak. Iam very concerned its my only car and I have 2 kids that I have to drive to school and daycare.
When I first got the car in 2007 about a week later got off the freeway got to the stop light the car shut off no warning signs, I was able to start the right up. The car has done this a few times (6) no mechanic can tell why this happens. I'm afraid that one day I'm going to be on the freeway and the car is going to stop and their is going to be a deadly accident.
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. …
My 2007 Ford Mustang has had a water leak under the passenger side area that has and is still causing electrical shortage in the car. Everytime it rains water gets into the vehicle and causes major damage. Ford dealership will not repair it under warranty and my out of pocket expenses to fix this problem would be enormous. This water leak is a TSB on Ford's site which means they know something is wrong with the 05-09 models. My car is now out of commision and will not start. I have replaced two batteries over the last year because of the water leak causing shortages in my car. This car is now a lemon beccause of the severe water damage Ford has caused my vehicle to receive. I have a vehicle that will not start and Ford will not repair without payment. I am sending this complaint so that a recall can be issused so I can repair my car. …
I pulled off the freeway into a rest stop area. My foot was on the brake, and only on the brake. I stopped in a parking space and moved the automatic transmission lever from drive to park. The RPM instantly increased from approximately 600 RPM in drive to approximately 6000 RPM in park. I took my foot off the brake pedal and gave the gas pedal a quick tap. The RPM returned to normal, about 750 RPM in park. The dealership inspected the car, but could not find anything wrong. They contacted Ford, who maintained the incident could not have happened the way I described it. They further told the dealership not to perform any repairs unless a similar incident recurred. The dealership thinks the problem is with the fly by wire, throttle body and/or control of the flow system. The consumer had concerns about brake fluid. The owner's manual stated to use dot 3 brake fluid. …
Driving at interstate speed car lunging acting as if the engine was wanting to cut out and then seems to 'catch'. I have since noticed it doing the same with in town driving. So speeds seem not to be an issue. I have done some online searching and have found Ford has issues with auto throttle body and the symptoms sound exactly like the issues I'm having with my car. I found this, and filed the complaint and am going to be in contact with my Ford service center in regards to the feb. 2014 update where affected owners should contact Ford and mention consumer satisfaction program 13n03. …
Tl* - the contact stated the throttle on his 2007 Ford Mustang gt became stuck, he had just shifted into 2nd gear. He was traveling at 25 MPH, but does not remember what speed the vehicle reached before he was able to stop.

The contact attempted to restart the vehicle and the throttle again became stuck. The failure mileage was 2489 miles. The vehicle was towed to a Ford dealership. The contact has not yet spoken with the dealer. Updated 6/9/08 the engine RPM increase instantly and caused the vehicle to speed up out of control. The consumer was a told the vehicle had a faulty mass air sensor. Updated 06/09/08
This has been a recurring problem that I have been experiencing for quite awhile. I was researching a lunge problem, discovered it is frequently happening to others. It happens when I am going a very slow speed. It has happened in traffic many times which is scary, in my housing developments, we have speed bumps so you must drive slowly and making turns. It just immediately all shuts down and the car stops. I actually try to avoid traffic on freeway because it has happened so many times. I have discussed, in the past, this with my mechanic various times and made sure everything in my car is fine. I have replaced everything and my car is well maintained. Extremely dangerous.
