Annoying Caddy

Owners of 2010-2012 Cadillac SRX vehicles may complain about a light vibration or exhaust noise under light acceleration load at 1,200 to 1,800 rpm. No misfires or codes may be present.

The concern may be caused by a resonance at the exhaust flex pipe. This is a dual-wall flex pipe, and the inner and outer sections of the pipe may be rubbing each other.

If this noise/vibration is present, loosen the flex pipe at both ends and allow it to settle. Tighten and re-evaluate. If the concern remains, replace the flex pipe.
