I bought a new Ascent three weeks ago and drove it off the lot with 3 miles on it. Now with 550 miles on it, I opened the hood for the first time and found this white substance all over the felt on each side of the engine compartment. What is it? It had of been there when I bought the vehicle. I have done no off roading, just simple to work and home commuting. It looks like battery sulfation. Any ideas?
