Service bulletin 14176B

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.

PIC5494F	2017-08-15. Service bulletin. This Preliminary Information communication provides information to the technician when the customer comments that their digital vehicle speed display is showing a different speed than the analog vehicle speed display. There may be up to 2 miles per hour difference between the digital and analog vehicle speed displays. This is a normal condition due to the calculation tolerances being different for the two driver viewing angles for the analog speedometer; it may also appear to increase the difference between both displays. No part replacement is required as this is a normal operating characteristic of the vehicle. For CTS vehicles built between April and June of 2011 or the 2013 ATS, SRX, XTS built before August 29 2012 may have a 3 miles per hour or more variation. The technician is to replace the instrument panel cluster for this concern.
