Two problems related to electric power assist steering system have been reported for the 2012 Ford Focus. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2012 Ford Focus based on all problems reported for the 2012 Focus.
Car has 122k miles. At the end of August 2021, the electronic power steering failed while my son was driving home from work, making the car difficult to steer while driving. The car displayed a notification of power steering failure. The dealer has had the car for two weeks, they confirmed a complete failure in the electronic power steering module. The dealer said they have to replace the entire steering rack at a cost up to $2500. I see this similar failure has led to a recall on the same year Ford fusion, but not on the Ford Focus. Clearly this has to be a manufacturer defect. 900 complaints in NHTSA for this issue and no recall issued.
Power steering was intermittent starting in 2014, usually on hot days or when driving for an extended period of time. By intermittent, I mean it would have power assist, then none, while driving with only a dash indicator "I". Finally, in 2016 the power steering utterly failed. Ford was unable to diagnose the issue if the car was not currently in the failed state. Ford wants the entire electronic power steering module replaced. Forums have indicated this is a known deficiency in heat-shielding the electronics within the module and failures while driving could lead to accidents and death.
