2007 Ford Mustang Owner Comments

problem #5

Mustang 6-cyl

  • 5,075 miles


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 contact owns a 2007 Ford Mustang. The contact's wife passed another vehicle at 60 mph and, when she attempted to decelerate, she could not. She released the accelerator pedal, but the speed would not decrease. She pumped the brakes, but the failure continued. Eventually, the vehicle shifted out of passing gear on its own and then decelerated. The contact had not taken the vehicle to the dealer or consulted the manufacturer. The current and failure mileages were 18,000.

Mustang 6-cyl

  • Automatic transmission

The car is a 2007 Mustang with 4.0L V6 and 5R55S automatic transmission. The car makes a whining sound when accelerating in 1st gear, and a lesser noise in 2nd. It seems to be coming from the transmission. I checked with several Mustang owners who told me that their cars normally don't make that kind of noise. Ford service checked the car and contacted the factory and concluded that the noise is from the planetary gears and that it's normal. They did no corrective work. Afterwards, I found that an earlier version of the transmission, 5R55E had problems with planetary gears which were replaced under warranty - tsb# 02-22-2. also, I found 2 or 3 people said that their Mustang transmissions made whining noises due to internal parts rubbing on the transmission case. In one case, the noise went away on the car after the transmission housing was changed. In another case the transmission failed. One person describes a similar problem in ODI id number : 10209790.

Mustang 8-cyl

  • Automatic transmission

Just driving normally, when automatic transmission reaches its operating temperature, a loud whine comes from the transmission in 2nd gear only. Brought the Mustang back to the dealer and the service advisor could not verify the noise and they refused to take further action.

Mustang 8-cyl

  • Automatic transmission
  • 2,500 miles
2007 Mustang GT equipped with the 5rss5 automatic transmission. "whining" sound coming from the transmission when in 2nd gear after it has reached operating temperature. Service advisor advised that its normal and no service is required even without mechanic to inspect the problem. Advisor did not write up service ticket. Later discovered a fellow owner had same problem and it found that the 2nd gear clutch was faulty and was rubbing the case from the inside causing the whining sound. Case was replaced and sound was gone. Another incident was discovered, and owner stated it led to complete failure due to metal particles circulating in the system destroying the other gears after prolonged use.
