Safety recall 14s05 -as a result of the recall Ford upgraded the software in my car in Dec. 2015, but three months later the steering failed. (the car was parked on a quiet san francisco street when I tried to start it and realized that the steering wouldn't work. ) I first towed the car to my local mechanic, who looked at it for a week and then told me that it was related to this safety recall; he advised me to take the car back to Ford. When I re-towed the car to Ford dealership, they refused to honor their written commitment to repair the problem and instead tried to argue that because I got a software update, their responsibility was over. When I asked if the symptoms in my car matched those the recall was meant to fix, the dealership admitted the symptoms matched. They say they can't do anything b/c a "code" didn't trip. I also noticed that the recall says that software upgrades "may" fix the problem and should at least notify the driver by beeping. My car never beeped, but more importantly a software update that "may" fix the problem is not sufficient for safety! the steering issue should be fixed/replaced by Ford! Ford is negligently putting customer lives in danger. Moreover, Ford shouldn't be able to push the cost of a malfunctioning, core product feature onto customers. When I purchased the car, at the top of the market price for it, I was not told "in 50,000 miles you will have to pay several thousand dollars for a completely new steering column because this one will fail and people in your car may die. " please investigate as many consumers are complaining about how Ford is trying to push responsibility for recall 14s05 onto individual car owners.
