Official summary

This Preliminary Information communication provides information to the technician about vehicles that may have a cold engine tick noise for 50 seconds at start up. Technician determines if the tick noise is possibly coming from the exhaust manifold, as this noise could easily be mistaken for an engine tick noise. If your SI diagnosis does not isolate the cause of this concern, this concern should be considered a vehicle design characteristic of the ECM calibration and no additional repairs should be performed.

Vehicles covered

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
