What is the 2003-2014 Cadillac CTS Ignition Key Can Move Out of Run and Disable Airbags (Recall 14V394)?

What is the 2007-2011 Cadillac CTS 3.6L LLT Direct-Injection Timing Chain Stretch Sets Cam-Correlation Codes?
The 3.6L LLT direct-injection V6 used in the 2008-2011 CTS (and the 2007 gen-1 3.6L LY7) is among the best-documented GM V6 failures: the primary and secondary timing chains elongate well before 100,000 miles, throwing off intake/exhaust cam correlation. Chain wear is strongly ac… Repairs typically run $1,800-$3,500. Severity: high.
What is the 2008-2014 Cadillac CTS Electronic Door-Handle Micro-Switch Fails and the Door Will Not Open from Outside?
The front doors of the 2008-2014 CTS do not use a mechanical cable to the latch.

The engine-driven water pump on the 3.6L V6 (LY7, LLT and LFX) develops a weep at the shaft seal.

Severity: medium.
What is the 2004-2012 Cadillac CTS 3.6L V6 Oil Consumption Driven by a Restrictive PCV Orifice in the Valve Cover?
The 3.6L V6 pulls crankcase vapor through a fixed-orifice PCV passage integrated into the valve cover rather than a serviceable PCV valve. The orifice sludges up and the baffle behind it does a poor job of separating oil from the vapor stream, so liquid oil is drawn into the inta… Repairs typically run $250-$800. Severity: medium.
