I have a 2017 Ford Edge and from time to time I get a strong chemical odor inside the cabin while driving. It's strong enough that I need to roll the windows down to air out the vehicle. Anyone have suggestions as to where this is coming from?

Also, at 50,000 miles, had to have the left front lower control arm replaced do to failed ball joint and at 55,000 miles had right front lower control arm replaced do to failed ball joint. (The dealer/Ford absorbed the cost of the second one)!
