We have a 2007 coupe and have been very happy with it. We recently started to notice a thin clear fluid on both sides of the car dripping on to the garage floor. This is mostly within about 16" behind the front wheel well and seems to be dripping from the rocker panels. No rust is evident. All the fluid levels - brake, oil, power steering, coolant and transmission seem to be stable and full. The fluid crystallized on the garage floor, is odorless and does not seem irritating to the skin. This has been happening in the summer in dry weather. The volume is not large ( maybe an ounce or two) but is persistent. The car has been washed several times since any contact with Michigan road salt (and we rarely drive it between November and April). The fluid was persistent even a week or more parked in the garage while we were on vacation over the summer. Any suggestions or similar experience?
