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.

WPB (POL 14-11)_2018-04-23. Service bulletin. STRUCTURE. WPB: Toyota has received reports where some vehicles may exhibit cracked and/or sticky/melting dashboards as a result of heat or humidity. In Mid-December, 2014 Toyota announced the reimbursement Phase of this warranty enhancement program. Since prior to that announcement, Toyota has been diligently making parts preparations for the parts replacement phase of this Program. Due to the age, volume, and breadth of the covered vehicles subject to the Program and the size and complexity of dashboard manufacturing, Toyota will be launching the part replacement portion of this Program in several phases; please refer to the table below for part replacement model phasing. Although Toyota is increasing production levels, it is difficult to predict customer demand and where parts need to be shipped to support customer demand. It is important that dealerships explain to customers that there still may be a period of time the customer will need to wait before part replacement can be performed. Please be sure to take this into consideration when performing customer scheduling.
