Service bulletins for the 2014 Jeep Grand Cherokee
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.

| 08-083-15 REV B | 2019-05-20. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. Flash: Bass, Mid, Treble Adjustment Causes Erratic Volume Increases This bulletin involves reprogramming the Amplifier (AMP) with the latest available software. The customer may describe when changing the radio tone settings (bass, mid, treble) the volume levels may be erratic. Depending where the volume is set, the volume changes may be very loud or very quiet. Example: When the volume is set to 8 and making adjustments to the tone settings, the volume can increase by 15 db. When the volume is set to 25 and making adjustments to the tone settings, there maybe no volume changes. The customer may also describe when listening with the volume set to 9 there is more bass and less mid/high. When the volume is set to 10 is less bass and more mid/high (WD,WK, W2 and W3 only). |
