I have been contacted by my dealership and was told they where told by GM that this situation with my rear window defroster is normal because the wires that go through the window are of different sizes? and this is normal for my 2011 Buick Regal.
I find this a VERY dangerous situation because it creates a large blind spot on both sides of the rear window. As a person that drives over 50,000 km. per year and mostly highway driving. This is NOT acceptable and it frustrates me to know I have been a GM owner for over 40 years and have never seen this on any of my vehicles. Nor have I heard of any other Buick Regal owners having the same problem.....
PLEASE GM look closer to the situation here before an accident occurs.
