2014 Ford Mustang Owner Comments

problem #7

  • 7,150 miles


This is the second time this has happened. Upon starting the car, the motor revs uncontrolled to about 7000 rpms. I have to turn ignition off to stop the motor from damaging its self. If my foot was to ever slip off the clutch, we would race uncontrolled in reverse! the car is always parked and started while in reverse. Almost afraid to start this car.

When downshifting in the manual transmission version of this vehicle, the car doesn't slow down on any decline and instead accelerates (without touching the gas pedal). Also, while slowing down on a flat road (at 1,500 to 1,700rpm) the car accelerates by itself and fights the brakes while in gear.

Mustang 8-cyl

Upon acceleration to pass a slow vehicle a strong odor started to fill the vehicle, almost like a propane smell. This I later learned to be exhaust fumes, or I should note, unburned fuel passing through the system. This is the 3rd time this has occurred, and only does this under acceleration when passing slower vehicles or using more power to ascend hills or mountain type roads. Vehicle thrown no ses codes. Vehicle does not stutter or hesitated, but as noted does produce a foul smell under harder acceleration.

2014 Ford Mustang. Consumer writes in regards to engine problems. The consumer stated she heard a ticking sound, after driving for 15 minutes. The dealer stated the entire long block needed to be replaced. After the long block was replaced, the engine light started flashing, and the engine was revving higher than normal. The vehicle accelerating by itself in gear and there were pressure issues with the brake pedal. The dealer was unable to replicate the consumers concern. The next time the consumer returned to the dealer, the ignition was replaced. The RPM's continued to rev, idle was very rough, even with the ac off. The ticking noise was still present, and the brake pedal was hard to the touch.

The car was making a dry pass by at a drag strip (non racing) while driving the car ignition cut off, causing a loss of control. Car hit rear quarter panel and then hit the front tire and suspension ripping the front bumper off. Driver was injured but not bad. Had car towed to a Ford dealer, where we were told we would have to pay $4,000 to have a Ford represenative look at, to determine cause for the car to shut off and air bags not deploy.

There is small jolt in the vehicle while driving. The motor then presses against the underpinnings and bottom motor guards. This is the second time this incident has occurred.

While driving the Mustang (which is a manual transmission) I noticed that the speed of the car doesn't decelerate when I take my foot off the gas pedal. The car is given gas (more than an idle amount) when I do not depress the gas pedal. It happens in all 6 gears but it's most noticeable when in first or second. Also, while the car is in gear, the engine fights to slow down while depressing the brake pedal. This doesn't happen every time but when it occurs while in a parking lot with people around it becomes a serious safety issue.
