Coolant leaks coming from the underbody on vehicles equipped with rear heat/AC are common. The underbody hoses should be inspected as part of regular maintenance. If you drive on roads where salt is prevalent the problem is generally more severe. Some 2005 models are involved in a special service action, no government recall was issued.Google+

Chrysler Town & Country Underbody Coolant Leaks From Rear Heat/AC Are Common
Chrysler Town & Country Problem

Bought car in Feb.2011 and in June A/C stopped working. Called Chrysler and they told me this wasn't a problem, however that was not true. Now because it has corrosion in the compressor my warranty won't cover the repair costs. Cost to repair is a whooping $1200. I do live in the Midwest where we have snow and they salt the roads, but really were they not expecting anyone who gets snow to buy their vehicles! This should be a recall!!!

Coolant dripping from rear near the passenger tire.

Metallic Coolant hoses are made of cheap white metal, that rapidly corrodes. Fix, replace all metal hoses before you wind up broken down on the road.

A/C was working for a week or two then would lose coldness. Noticed antifreeze on ground on driveway. finally figured out that connection between metal tube and rubber hose was bad due to corrosion from road salt.
