I have an 07 SEL+ FWD, found slighty red fluid on floor in garage, took to dealer immediately, they saw fluid but could not find where it was coming from,( it was on drivers side just behind half shaft ) then I remembered I was on the highway and had the OD off for about 12 miles, I was doing 70mph. No more leak, only thing I can think of is it had blown some fluid out the vent hole, hasn't leaked since. Great car, has 6500 on it and am getting 21.8 on highway, it has been improving since 5000 miles, and am pleased since most of the time I have 5 people in the car....
