Service bulletin CC-20-90-02
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.

To promote the best possible customer experience, a replacement ESM should be installed prior to delivery of the vehicle to prevent any possible concerns or replace the module as per this bulletin if already delivered.
