On the 2009-2014 Cadillac CTS-V, gM PI0430C covers 2009-2014 Cadillac CTS-V vehicles with Magnetic Ride Control when the Service Suspension System message appears with DTC C0575, C0580, C0585 or C0590. A 90-degree electrical connector at the top of a shock actuator may be incompletely seated or partially disconnected; the bulletin does not establish universal shock failure.

Common Symptoms

  • Service Suspension System message

How to Fix

Follow PI0430C connector inspection, seating and circuit checks before replacing a shock absorber. Continue normal service-information diagnosis if the connector path does not resolve the message or DTC.

On the 2009-2014 Cadillac CTS-V 6.2L Supercharged V8 (LSA), gM special coverages 13313 and N192210220 identify a bounded 2009-2014 CTS-V LSA supercharger condition: excessive rattle or knock is strongest at idle and usually fades as engine speed rises; progression can contaminate grease, produce bearing squeal and eventually damage or seize the supercharger. GM distinguishes this from normal low-level mechanical supercharger noise.

Common Symptoms

  • Excessive supercharger rattle or knock at idle
  • Bearing squeal
  • Possible no-start if the condition progresses

How to Fix

Have a Cadillac dealer verify the VIN, installed supercharger and exact noise pattern before replacement. The published special-coverage periods were time- and mileage-limited, so current eligibility and cost must be confirmed rather than assumed.
