Our technicians tell us that some vehicles may require a powertrain control module (PCM) software update to correct this issue. Other vehicles may have excess camshaft end play on one or both cylinder heads which will need to be corrected using special procedures outlined by GM.
The rear axle pinion seal may leak causing fluid loss and possible internal rear end damage. Replacing the faulty seal will commonly correct this concern. Some 2005-2007 models have been recalled for this issue.

2006 Cadillac CTS RecallsFuel Pump Failure And Leakage
The engine may stall and fuel may leak due to overheating of the electrical terminals in the fuel pump module, resulting in the melting of the flange material. Dealers will replace the fuel module and fuel tank jumper wiring harness free of charge to resolve the concern.
The weight on the key ring and/or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine and increasing the risk of a crash. In the event of a crash, if the key is not in the run position, the air bags may not deploy as expected. Dealers will provide two replacement key rings, and vehicles with slotted keys will receive key inserts to correct this concern. Note: Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring.
General Motors is recalling certain 2005-2007 Cadillac CTS vehicles. The front passenger seat occupant sensor may become damaged, disabling the passenger airbag and illuminating the airbag warning light. If the airbag does not deploy when needed, there may be an increased risk of injury to the front seat passenger. Dealers will replace the front passenger sensing system free of charge.
