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. Although one of the most likely situations is going up a hill, turning slightly to the right while slowing for a yield sign but not stopping and then pushing the accelerator only to get a hiccup or choke or whatever you want to call it. There are also issues filling the tank because of a lack of enough space for fuel to replace air causing the self-shutoff of the pump to kick-in not filling your tank. I raise this up as this could be some type of pressurization consistency. There's also the aggressive accelerator where you push it a tiny bit and it wants to take off enough to squeal the tires sometimes.

The transmission would not go into overdrive on the highway so I pulled over and then the automatic transmission had to be manually switched from gear to gear and then drove fine. The the vehicle starts doing the same thing after warming up. Now reverse and 3rd are out when the vehicle is warm. Ive had sensors bands and other things replaced. Everything short of a new transmission has been replaced. Now I cant find a transmission repair shop that will rebuild it due to so many problems with these transmissions they do not want to put a warranty on it. Please look into this problem. It needs to be a recall. Something is clearly defective or licensed technicians would repair them and wouldnt care to offer a warranty. My vehicle has had transmission problems off and on since 2017. This is ridiculous that all the complaints have not resulted in a recall.

Ford oem part no.: 8R3Z-7210-C - shifter assembly automatic console shiftier blind may bind up in the track or break completely like mine did. This can cause difficulty in the shifter going in to gears or park, or show proper P R N D 3 2 1 selection on selector. A broken blind can allow things to fall down into the gear sector, that could cause gear selection or park not to work properly. Stationary or moving I don't see how this is a this is a unsafe condition of the part. The whole part has to be replaced at $283 + labor unknown as they do not sell replacement rebuild parts to fix the automatic shifter. Https://www.youtube.com/watch"V=xerutmnrwig https://www.youtube.com/watch"V=en5ijpmhwlk keep in mind people trying to fix the problem themselves generally leave themself with no gear section indicator because Ford does not sell parts for rebuild, only to replace the whole thing.

The clutch is slipping at only 10,000 miles, the car cant even make it up a gentle grade with the cruise control on ! it cannot maintain speed it cant handle when you give gas to accelerate to freeway speed when entering the onramp to freeway. This has to be the slowest shelby on the road.

The vehicle while shifting gears is in 3rd gear is changing RPM's. the RPM's are moving vastly from lower end to top end. The car has very low miles and recently purchased 7 months ago and only placed 3000 miles since purchase. The warranty company will not cover the problem. I reached out to Ford because there are some forums that state this part that is making car do this is the clutch and gives out very early after manufacturing of the car, they said they are unable to help me but if there is a recall they will let us know. We feel this part is defective to give out in 3000 miles since purchase and see there are several people with same complaints online.

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.

In traffic transmission intermittently locks you out of 2nd gear. Ford would not repair under warranty their tech said repair might not resolve the issue and might make the problem even worse. Vehicle is a bit dangerous and unnerving to drive in traffic, especially heavy traffic. Suspension bounces vehicle up and down heavily on the interstate at interstate speeds. Vehicle is a bit dangerous and unnerving to drive at interstate speeds on the interstate, especially if the road is course and curvy.

Affected parts: Clutch. The clutch has required replacement (slipping) three times in 44,571 miles. First problem occurred at approx. 10,000 miles (replaced by Ford under warranty). The second problem occurred at approx. 24,000 miles (replaced by Ford under warranty). The third problem occurred at 44,571 miles and Ford is refusing to do anything, the Ford premium care extended warranty refuses to honor the extended warranty. They now claim it is a "maintenance" issue. My vehicle is a 2007 shelby Mustang GT500 and it is not listed in the above drop down box.

I was driving eastbound on the 91 freeway in California. I went to accelerate and the accelerator revved up and increased my speed to over 90 miles per hour which I had no control of. I realized that the accelerator was stuck and put my car into neutral. I was able to come to a stop on the side of the freeway with the help of a dirt field without doing this I would have crashed and either been killed or I would have killed someone. I contacted Ford corporation about my problem and they insisted that this was the first time they have heard of a Mustang doing this. I researched this online and apparently this is happening alot with the Mustang. My car has only 33,000 miles on it.

- Stanton, CA, USA

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. However, the dealer used dot 4 brake fluid. Updated 11/09/15.

When I start my car in the morning, and it is overcast out or has just rained, my shifter will not go into first or reverse. It takes a few minutes until I can force with all my strength the knob into gear. As I am driving though, I still have a hard time getting it into first gear after a stop, and many time cars have had to go around me into oncoming traffic and a few times have come close to an accident. The first dealer I went to in victorville told me to bring it back when it is acting up really bad. I brought it there one day when it was acting up and they told me they would get to it later. I called them a few minutes before they closed and they said they found nothing wrong, so I insisted to leave it and have them try it in the morning. The next day I called right before they closed again and they informed me everything was working fine. When I went to pick it up, I noticed they had not put even a mile on my car after checking the milage. I drove home and on the way home it was acting up very bad so I went back and told them. The guy that runs the counter went on a ride with me and I showed him when it happened and he said he thinks I'm probably not pushing the clutch down all the way and basically blew it off. I was a little insulted by his assumption of my incompetence, so I contacted Ford corporate about my issue and they said I should possibly try another dealer. A week later when I was getting my oil changed at a shop, they informed me that my water pump had a large leak. I took my car into the dealer in san bernardino, where they fixed the leak, but once again found nothing wrong with my shifter, and also found that my transmission was leaking. I went to a dealer in san diego when my car was still acting up bad, and they fixed my transmission leak, which took 10 days, but said my shifter was working completely fine.

The first indication that there was a problem was when the car would not shift into reverse. I noticed this and mentioned it to the service writer when the car was in for a routine oil change. I was told to try different things to get it to go into reverse more easily. Soon after the reverse issue I started the have problems shifting into gear while driving. The car would not shift into the next gear at times. At some point the car started to slip out of gear while accelerating. This can be dangerous when merging into traffic. I at first thought maybe I was at fault, but soon realized that the problem was with the car. When I investigated the problem I found out that this is a known defect. There was a tsb put out on the model years 2007-2009. Ford never informed us the issues with the transmission and/or clutch. Now they tell us that our 3/36,000 warranty has run out, so that if the clutch is part of the problem it won't be covered. Ford should have informed the owners of this potentially dangerous defect in the car. They obviously knew about it, and did repair many of them. I realize that the newer model years are also having these issues. There should be a recall put out on these cars. There are many shelby GT 500 owners who may not know about this safety issue.
