Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving the vehicle at 60 MPH started to smell anti-freeze. When I checked the engine compartment. I found that the left side of the plastic, intake manifold had cracked an was leaking anti-freeze. Contacted dealer, they wanted $580 for a new manifold plus labor to put it on. I feel that if a manufacture puts an intake manifold on on of thier vehicles it shoud last for the lifetime of the vehicle and should not have cracked, I think this is poor enginering, and should be replaced free of charge by the dealer, since Ford has replace all police vehicle intakes.”
NHTSA complaint #10086925, filed 2004-08, 88,900 miles“While driving vehicle overheated on its own. Vehicle hesitated while accelerating, then stalled. Consumer was unable to restart vehicle, and had the vehicle towed to dealer. Mechanic determined that the intake manifold needed to be replaced. This vehicle was not recalled by VIN or under warranty. Consumer informed the mechanic that part number f8a2-9424-bc, notification #97m91 for intake manifold was recalled.

NHTSA complaint #10090056, filed 2004-08, 107,000 miles“The stalling problem is a major safety hazard. The car stalls when the brake pedal is depressed (in neutral gear). The power steering and power brakes also lose power, causing me to do whatever not to crash. I know of other mustangs noticing the same problem. My car was serviced at the dealer for this specific problem, but failed to fix it.”
