  • Automatic transmission
  • 41,000 miles
A valve keeper inexplicably failed on my 2005 Ford Mustang with only 41,000 miles on it causing the #4 cylinder valve to go into the cylinder and damage the piston and cylinder. End result need a whole new engine.

problem #4

Oct 252005

Mustang 6-cyl

  • Automatic transmission
  • 5,700 miles
Purchased vehicle in 4/05-problems started in 10/05. Engine light on and engine idle rough on 4 separate occasions. Two sensors, a solenoid, and spark plug replaced on those occasions. Now car is at dealer because it will stall when idle and lose power. This is really not safe when you are entering traffic! still waiting for the outcome of this. The fuel sending unit needed to be replaced due to erratic fuel gauge-the gauge would show empty when the tank was full.

problem #3

Mustang 6-cyl

  • Manual transmission
  • 500 miles


- the contact stated that while idling the engine would suddenly rev up to 2500 RPM. The 2005 Ford Mustang would then lunge forward, causing the vehicle to accelerate without touching the gas pedal. The contact stated that he has been experiencing this failure since he purchase the vehicle. The contact currently has the vehicle at sheltz Ford and this is the first time he has brought it to this dealership, but took it to four different dealership trying to fix the vehicle's malfunction. The dealerships stated that there isn't anything wrong with the vehicle and that he might be driving the vehicle incorrectly. Updated 1/29/2006 - when the vehicle was taken to the dealer they informed him that the high rev would go away and that it was a normal break-in condition.

problem #2

Jul 032005

Mustang 6-cyl

  • Automatic transmission
  • 2,500 miles
After driving my Mustang approximately 1 to 1 1/2 hours at highway speeds, I exited the interstate. At the top of the ramp I attempted to merge into traffic but when I pushed the accelerator the car shut off right in the path of oncoming traffic. It did restart so I avoided being struck. Since then it has done it several times even while driving along then accelerating. I have had several close calls due to this problem. I have returned the car to the dealership on three different occasions. The first time, they replaced a O2 sensor. The last two times they said they can not find a problem.
