I have a 2013 Edge. For the past year it has been having intermittent steering problems. They typically occur when changing directions (in a parking lot) going from park to reverse to drive, and when turning into parking spaces. The steering gets stiff and you need to "muscle it" to make direction changes. It feels like a huge truck in 4 wheel drive low. The dealership has tried for a year to replicate the problem. Finally a service manager was driving car and felt the problem. They replaced the entire power steering system.'This did not correct the problem. Now they tell me the car drives fine, but it does not under the circumstances described above.
