| 31000 mi | Radiator fan made squeaking noise as it wound down after shutoff. Tech and service advisor heard the noise. Said they would order the part. Came back a week later Had not ordered the part because it cost over $500 Lead tech did not hear it. Right radiator fan squealing on shut down and cold starts. Dealer finally fixed the problem. This time I left the car, received a G37 loaner and have since sold the car. |
