Known issues on the 2013 CTS. Two recalls are on federal record for this model year. The first covers the ignition system: if the key is not in the run position, the air bags may not deploy in a crash, increasing the risk of injury. The second covers the electrical system, where the chassis electronic module can be internally contaminated and short, which can cause the vehicle to stall and increase the risk of a crash. Owners have filed 72 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're tracing a stall-inducing short in the chassis electronics or working through a supercharged LSA service interval, it keeps you on the OEM procedure and correct specification for your specific 2013 CTS.
