One problem related to vehicle shudder has been reported for the 2008 Ford Focus. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2008 Ford Focus based on all problems reported for the 2008 Focus.
The vehicle does not exceed 50 mph. The car would stall and jump under the hood. The car does not accelerate up hill. The car also shakes continuously and roars loudly when 40-50 mph is reached. The wrench light comes on when driving but the wrench light also goes away when you restart the car. I took the car to mechanics who stated they could not service when wrench light is off. When I did take it to the mechanic when the wrench light was on the mechanic plugged up a system and informed me that it must just be a sensor. I avoid highways because the car does not accelerate after 40-50mph. I am concerned for my safety when operating the vehicle. I do not feel safe. I rely on my vehicle and am disappointed, afraid and uncertain what to do.
