Date: April 29, 2009
Subject: Exhaust Rattle Noise from Center of Vehicle at Idle and Partial Throttle (Repair Exhaust Heat Shield with Clamp)
Models:
2008-2009 Cadillac SRX, STS
Condition
Some customers may comment on a metallic sounding rattle heard from the mid-section of the vehicle. The rattle can occur during both hot or cold
exhaust system conditions and at engine idle and/or partial throttle.
Cause
This condition may be caused by a cracked exhaust heat shield on the right front inlet pipe of the muffler assembly. The heat shield is typically cracked
at the rear weld to the pipe, which allows a rattle between the shield and the pipe.
Correction
Important
DO NOT replace the exhaust system or muffler for this concern.
1. Locate the exhaust heat shield on the right front inlet pipe (1). Verify that the heat shield rear weld to the pipe is cracked and loose from the pipe.
