I have a 2007 EL EB and have had my share of quirts and issues. Some bigger than others. I bought mine of my folks a couple years ago with only 115K on her, now at 160+.
Currently having a front vibration issue with speed. Noticeable at 60 MPH+ and when I even tap the gas on the highway. Occasionally shakes just accelerating on any road. I'm guessing either mounts, control arms, etc in the front. Gonna get it checked out when I go in for an oil change in a week or so. Hopefully not major.
Second is brakes. I replaced the rotors and pads last summer with HD Powerstops (cross drilled) and they worked good until I cooked them on a long trip from GA to NY and back. Lots of trucks pulling out and had to brake hard with it loaded down with family, luggage, and a roof storage box. Probably need the front replaced. But I have always had crappy brakes with this thing. I'm guess in need to replace either the lines or a caliper rebuild. Just don't have the time I used to as the kids have gotten older and need more "dad taxi".
EVAP leak, but I've just limped it along with cans of refrigerant from Autozone, $40 versus $1500. Easy choice. As long as it cools we are good. Cooling seats don't work, but heated ones do (I fixed those myself when it burned out 1.5 years ago)
Other than those I get compliments all the time on how clean it is and how good the paint is, etc. I keep her clean and tinted all the windows dark so its a good ride. Armrest and drivers seat is starting to crack a bit, but minor.
Overall its a good vehicle, but not as reliable as my Sport Trac (2003 XLT) was, but it has a lot more options on it.
