The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.

I thought the radiator was running hot. Had that fixed but it continue to run hot, then I found out it was was the in take manifold now it is being repaired and the cost for me is $1700.00. I am not a happy camper.
Small coolant loss at first. Later, when engine rpm are increased, coolant blows out big time, appearing to come from the area behind the alternator up toward the fan. Drive-ability is not feasible until repaired. I'm still weighing my options, a year or more later. This makes me very disappointed and displeased with the quality of this important part, on a so called "luxury car". Come on Ford/Lincoln/whomever, you can do better than this, if nothing else, stay with the tried and true metals of years ago.
