Consumer Description

The cylinder head cracked while waiting for a light to change at a busy intersection, causing heavy smoke to enter the vehicle through the air vents with the heater on. The smoke filled the car quickly, causing my wife and me to exit the vehicle at the very busy intersection. A local independent service center diagnosed the problem. I was unable to drive the vehicle to the manufacturer for safety reasons and smoke filling the cabin. No warning lights were displayed. This vehicle was maintained following the manufacturer's recommendations throughout its 77,000 mile life.
