Grinding/rattling noise and heavy shuddering/shaking/lurching occurs at low speeds. Not normal sounds. I drove manual vehicles for over 15 years and never experienced this occurrence, with the exception of first learning how to drive a manual. It is currently in the shop for a recall (that this site doesn't note, for some reason, but Ford does find). I have never once (2 months time) gotten over 31 mpg either. This was purchased as a commuter vehicle, and for it to rarely get 30 mpg is sad, considering my driving an 8 year old, 175k mile corolla meant getting upwards of 34 mpg consistently. Have made 2 payments on the car and wishing I had never bought it.
I have only had to car for a day. The car makes an awful rattling noise and hesitates when going in and out of traffic. To make matters worse, today I was in a parking lot and when I was in drive I pushed the gas to go forward and the car went in reverse! please recall this car. It's so unsafe and someone is going to get killed. Luckily no one was behind me when this happened. Awful transmission. A danger!.
