I had a friend who had a new car.  One morning it would not start.  
Called the dealership and the dealership had it towed to the shop.  The 
mechanics could not find any fault and gave the car back to the owner.  
Next morning same thing, no starty.  Another tow and another "nothing's 
wrong".  Next morning, again no starty.  This time he called owner of 
the dealership, I believe at home.  The owner, service manager and a 
mechanic came to the car and saw first hand it would not start.  Turns 
out dust from the clutch was landing on an optical sensor that detects 
rotation in the flywheel.  The computer would not turn on the gas pump 
until it detected the flywheel was turning.  Towing the car to the 
dealship on bumpy rural roads shook the dust off of the sensor.
