Service bulletin Circular 24FN

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

A software error in the Engine Control Module (ECM) prevents the remote start running time counter from being reset when a driver cycles the ignition. Instead, after 20 minutes of total remote start running time is reached, any further attempts to use remote start will be cancelled automatically (the engine will crank, run momentarily, and then stop). The software also includes on-board diagnostic (OBD) updates to improve vehicle diagnostics.

The document
