New showroom 2002 Mercury Mountaineer. The engine in this vehicle malfunctioned twice without warning; no overheating, no dashboard light indicators either time. July 2004/odometer reading 92213, the mechanics at the freeway Lincoln Mercury were baffled. They advised me that all the fluids were in the vehicle. Later (one week) they found a "hole" in the radiator.
