Car Maintenance & Repair Advice from The Factory
Factual explanations from our technical team — what a symptom usually means, what diagnosis involves, and when to get it looked at.

Squeaks are often caused by pad wear indicators, glazing or dust. Light noise after rain can be normal; persistent squealing, grinding or vibration should be inspected.
