Owner reports
Selected complaints filed with NHTSA by 2007 Ford Mustang owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2007 Ford Mustang. The contact stated while driving and depressing the accelerator pedal, the vehicle failed to accelerate as needed. The contact indicated that when the accelerator pedal was slightly depressed the vehicle decelerated. The vehicle was taken to the local dealer who diagnosed that the clutch was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure and the contact was informed that an extended service for the failure was issued but the VIN was not included. The failure mileage was 17,000.
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. …
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 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.
06/30/09 7973 miles 15 months old brought car to dealer for leak in manual transmission at drive shaft. Seal changed. Brought car to dealer 02/26/13 same leak, seal changed. Car to dealer 02/19/14 same leak, change seal and flange. Flange defective, unable to exceed 30-35 MPH. Back to dealer. Two more flanges installed and found to be defective. Picked up 02/28/14. Car to dealer 02/12/15 now out of warranty needs seal,flange and now a drive shaft, cost1100 dollars. Feel if this is the real problem causing leak dealer misdiagnosed for too long. Now I'm stuck paying repair bill.
While executing a left turn across a six-lane intersection, I noticed another vehicle approaching the left side of my vehicle at a speed of at least double the limit. I accelerated hard to get out of the way. The throttle "stuck" for an estimated two to three seconds which caused loss of control and impact with a foot high curb at the far side of the intersection. Damage to my car was over $8,000.00. There have been no repeat episodes to this date.
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.
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.
Tl* the contact owns a 2007 Ford Mustang. While driving at 60 MPH, the vehicle decelerated without warning. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 5,500.
I drive a 2007 Ford Mustang. At 7:00 am on my way to work my car decided to turn into christiene. : -). The throttle body or the accelerator decided to stick. The RPM's were racing. I burnt up the back brake pads and the rotors, of trying to get the car to slow down. I even tried gearing the Mustang down. When I finally got to a safe spot, I then turn off the ignition. I started it up to if sitting and resetting the computer would fix the problem. I pressed on the accelerator and the problem started again. I started the car three times and I got the same response. After setting for a hour and a half I pressed on the accelerator again. It was fine. I did immed. Took it to a near by Ford dealership to have them hook it to a computer. …
