SUBJECT:
Diagnosis/repair of buzzing noise from front while driving
REFERENCE:
VIDA, VRC2, STB # 002
Description
There may be cases when a buzzing noise can be heard from the front of the car during normal driving. The noise may become louder as the vehicle
speed increases. Sometimes the noise can be more pronounced in a curve or when driving above a certain speed.
Diagnosis
There is no substitute for obtaining a complete and accurate understanding of the customer's symptoms. VRC2 contains a wealth of best practices and
resources on how to manage the customer service process. (Find these links under > Operations > CSI Improvement Tools.) Briefly, a technician should
be certain that he/she possesses thorough knowledge of the customer's symptoms before beginning a repair attempt. In many cases, especially cases
involving noise or an intermittent symptom, this should include a road test with the customer to verify the symptom.
