Subject: | Rattle/Buzz Noise from Exhaust System Under Slight Load (Replace Exhaust Resonator) |
Models: | 2004 Saturn VUE Vehicles |

Built Between VIN Breakpoints 4S821610 and 4S855617 Inclusive |
Attention: | Fixed Operations Manager and Technician |
Some customers may comment on a rattle or buzz-type noise while driving vehicle at engine speeds between 1,800 and 2,200 RPM. This condition may only be evident with the engine under load.
This condition may be caused by a cold weld inside the front exhaust resonator (mid-muffler) assembly.
Verify that the exhaust resonator (mid-muffler) is the source of the noise by duplicating the noise at engine speeds between 1,800 and 2,200 RPM under load.
• | If the noise is NOT determined to be coming from the exhaust resonator (mid-muffler), refer to "Diagnostic Information and Procedures -- Exhaust Noise" in the Engine Exhaust section of the 2004 Saturn VUE Service Manual, Vol. 1 (SI Document ID #1271655) to diagnose exhaust system noise. |
• | If noise is coming from exhaust resonator (mid-muffler), replace exhaust resonator (mid-muffler). Refer to "Mid-Muffler Replacement" in the Engine Exhaust section of the 2004 Saturn VUE Service Manual, Vol. 1 (SI Document ID #1272104). |
