2007 Jeep Grand Cherokee Limited 4dr SUV (4.7L 8cyl 5A)
We have had our Jeep in for service 3 times before the first payment is due. The Evap. System has been replaced. The check engine light hasn't gone on since but it seems as soon as we fill with E85 the gas mileage (not great to begin with) plummets to 14 miles per gallon. we expected a "slight change" but not a 5 mile per gal difference.
I love Jeeps. This one has the best ride of all of them I have been in.
The dealership/service department doesn't seem to know enough about the FlexFuel to answer our questions.
