Greetings,

What year, make model, and engine size? Where is the knocking noise coming from? Under the dash? In the engine area?

2009 Saurn Vue, 4 cyclinder. It sounds like it is coming from underneath the car. I only hear it when the car is in motion
Expert:  BigBob replied 8 years ago.
Many things can cause these symptoms. Have you had any service work done lately, like oil change or tire rotation?

There are some TSB bulletins for Saturn making knocking noise in front suspension and steering shaft of vehicle. It could be as little as a rock in brake backing plate, or the exhaust could be hitting the frame, driveline bushings could be bad, since it is under warranty probably, get it checked right away. Without hearing and seeing it very hard to diagnose over internet.

Good luck,
Bob
