I just had to deal with this issue, which caused me to find this forum
To say that dealing with my Ford dealer and Ford Canada has been a nightmare is an understatement.
The gist of it all is I had the intermittent wiper issue, which as has been shown in this forum, is caused by the faulty wiper arm.
My 2013 Edge was purchased in October of 2012 and I made my appointment to have the issue looked at on Sept 28 2015, and the dealer
scheduled me in for October 2nd, 8 hours after my warranty expired. The "service desk" clerk said oh sorry we can't cover that it's not under warranty,
and I told him well you scheduled me in for this time so cover it, all I got in return was sorry you can pay for the service today and we will gladly look at it for you.
Flash forward to today, after dealing with Ford Canada over the issue, I end up paying 140 for the replacement.
Wish I found this Forum earlier, But more importantly I wish I never purchased a ford. This combined with 3 other issues I've had with a vehicle with 35000 kms has been an absolute joke. To say DONT BUY A FORD EDGE would be a drastic understatement.
