Was stopped at light vehicle steering would not turn i put the car in park turned off engine then on. steering work ok for time being. definitely a safety issue
I was driving at 70mph and started receiving warnings about my advance trac. i that point i slowed down and pulled over and lost all power steering.
Power steering suddenly failed. system warned of vsc fault, then steering assist fault, then there was no power assist, at 50mph. i was driving straight on an airport access road. the problem persisted for a 2 miles or so, when i was able to get it off the road safely. when i turned off the ignition and re-started a few minutes later, the problem was gone, as were the warnings.
On july 5, 2018 i was driving at 35 mph on a city road when a warning light with the words "steering assist fault, service required" suddenly came on and the steering stopped working almost entirely. there was very little manual ability to steer the car. fortunately we were on a very wide, empty road, so i was able to use both lanes and get the car to my house. if this had occurred on a busy city street or narrow lane, with any kind of traffic, we could have easily been in a serious, even fatal collision. i hope that other ford owners will report this problem if they experience it, so that a recall can be initiated if needed. this was a dangerous system failure that should be investigated.
My power steering failure indicator came on (while i was driving), indicating a need for immediate service. upon testing, it was determined that the steering gear was faulty...on a 2015 vehicle!! this could have caused an accident if the gear failed while i was driving. i would not expect such a failure in a 2015 vehicle. it looks like previous ford models have been recalled due to a similar issue. i think there must be a design or manufacturing flaw. given that this is related to steering and creates a high risk of injury in the event of an accident, i recommend that this be fully investigated.
