On the 2005-2007 Cadillac CTS-V, certain 2005-2007 Cadillac CTS-V vehicles have a drive-axle differential seal that may leak because it did not meet GM specifications. Continued lubricant loss can increase differential noise, overheat bearings and, in an advanced case, allow the differential to jam or lock the drive wheels.

Common Symptoms

  • Open safety recall
  • Differential-fluid leak
  • Increasing rear-differential noise

How to Fix

Check the VIN and recall-completion history. GM campaign 07204C directs dealers to replace the affected drive-axle differential pinion seal; confirm current campaign status before service.
