Ed, all I can say is that is what my service tech told me. He is not with any dealership and is a certified independent tech in the area. I frankly would trust him over any dealership tech. I'm not an engineer so I can't tell you Yes or No on the subject but this is what I was told. It may have been air in the lines but it was funny that it only happened in the early spring when the weather was starting to warm up some! I'm just a Nebraska farm boy and don't know to much about these new fangled things!
