2012 Ford Mustang Owner Comments

problem #3

Dec 202014

Mustang 6-cyl

  • 60,300 miles


Driving down the highway full speed in heavy traffic, and engine just shuts down. Wrench light and check engine light come on. Have to coast through traffic to pull off to the side of the road and stop. Restart the car a couple of times, and then it's fine. Took to Ford dealer, who said I had a bad throttle body. Charged over $800 to repair. Completely losing power while driving down the highway is definitely a safety issue! Ford has agreed to fix defective throttle bodies on other models, but not the Mustang. This really looks like the same problem, and should be addressed by Ford.

Fuel system problem: Evaporative emissions system related failure, fuel fill neck failure (possibly at connection to fuel tank) and unknown other leak. Dealer claims not covered by California or federal emissions required warranty. Dealer reports seeing fuel filler neck problems on Mustang and other Ford vehicles. (possible concern for fuel or vapor leakage, safety related concern) Mustang uses "nascar" style fuel door that is clearly suspect, doesn't stay sealed tight, opens unexpectedly and allows raw fuel emissions into atmosphere. Prior software patch applied to ECM due to nascar style fuel door at 2,900 miles.

problem #1

We were driving on the freeway and the car started acting like it was running out off gas. The steering wheel jerked and the brakes locked up. We now know the problem occurs only when someone sits in the back seat behind the driver. We have duplicated the problem numerous times. Sitting it the back seat causes something to short out and the car dies. This was very dangerous in real driving conditions and we are lucky no one was hurt.
