For the fifth time in only eight months, the transmission has malfunctioned in this vehicle, causing it to stop accelerating or stall. It is a safety hazard, as it has happened on the highway twice and has been on the street in motion the remaining three times. Each time we have taken it to the shop at the owner's expense and it has required towing each time because it no longer accelerates. The transmission sensors (there are two) continue to misfire and fail, despite being replaced several times. This car was bought new in 2012 and has had issues since the purchase. We have two children and another is due at the end of January and I do not feel safe driving this car, as it has almost been the result of several accidents when it stalls and shudders.
The contact owns a 2012 Ford Focus. The contact stated that the vehicle was not shifting into gears properly, would stall sporadically and would jerk intermittently. Additionally, the steering wheel would often seize. The vehicle was taken to an authorized dealer several times who had not been able to replicate nor diagnose the failure. The failure recurred and the dealer replaced the transmission and transmission sensor but the failure recurred. The contact also mentioned that the lights intermittently illuminated and the radio was making a loud noise when it was powered off. The vehicle was taken back to the dealer who then diagnosed that the computer chip in the fuel pump failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 30,000.
