Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Coolant leak from crack in plastic intake manifold. This car only has 97,130 miles on it and well cared for. They should not be using plastic in this application - it should be iron or aluminum. This is a common problem I was told with the 4.6 v8 engine. Ford needs to recall these and replace at no cost to customer. I will be writing a letter to ford if the dealer doesn't cover this as a recall. Ridiculous to use plastic in this application.”
NHTSA complaint #10682192, filed 2015-02, 97,130 miles“While driving home on interstate 35 north of minneapolis, mn, the intake manifold cracked and lost anti freeze. Pulled off the highway at forest lake, mn and had to be towed to tires plus in forest lake to have the car repaired. Total cost for towing, intake manifold replacement and nights lodging came to almost $1500.00.”
