Selected complaints filed with NHTSA by 2010 Ford Focus owners, lightly cleaned up (personal details are redacted by NHTSA).

When driving this car and the speed reaches about 40 MPH the traction control light comes on and the car reduces speed and you can push the pedal all the way down and it will go no faster than 30 MPH. The only fix is to hit the traction control switch on the dash and this turns the traction off and allows you not to get killed. I took it to the shop to see if any trouble codes would pop up and the scan said the car was fine no issues. When you drive the car it tells a whole different story .it will not be long until some one gets to an intersection and a truck is barring down on them and the car will not safely accelerate to get you out of danger. I have found nothing that will fix this problem so I will try to sell it back to a dealership. Sad thing is we still owe $5000. On it but don't feel safe in it. …

This vehicle is part of the national fleet owned by the us postal service. The driver was trying to come to a complete stop at an intersection. The engine began revving as the driver was applying the brakes. The additional acceleration made it impossible to stop causing the Focus to collide into the rear of the vehicle stopped ahead. The Focus engaged the stopped vehicle once, pushed it ahead, then engaged it a second time. The vehicle was taken to a Ford dealership where nothing was found to be wrong. This incident is consistent with past complaints filed with NHTSA for same model year Ford Focus vehicles.

I turned on the engine in the morning and the car seem to start fine, but when I put the gear selector in reverse and pressed the gas pedal suddenly the check engine came on and the car started shaking violently, I instantly turned off the car after a few seconds I tried turning the car back on, the check engine light went away, and it seem to work fine after that, but this now happens on a daily bases at random times of the day, I checked the car with an obd2 scan tool and it had codes p2111 and p2135 this keeps happening even after replacing the gas pedal and the throttle body

Two of those occasions occurred recently in March and April of 2017. On those occasions, it was not possible to stop the vehicle by normal braking.
