During a random under-hood inspection of my wife's Escape (too much time on my hands!) I pulled the battery cover and noticed a lot of corrosion (green fuzz) on the forward battery terminal. Took it in to dealer on 5/1/2015 (just under two years and 11,986 miles) for inspection. They cleaned the front terminal and stated that the battery tested 100%. One month later corrosion had reappeared and I returned to dealer. On 6/1/15 they replaced with a new "maintenance free" battery.
I am happy that they replaced the battery under warranty without any hassle. The Escape, along with most newer cars, depends on the battery for essentially everything... without it the vehicle will not run. You cannot access the rear cargo compartment if the battery is dead. In the future I will replace the battery every two years. My cost will be approximately $5 per month... I figure the peace of mind is worth it.
