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.

B18070B2018-08-06. Service bulletin. EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY. Service news article - If the On Demand Multi-Use Display? (ODMD) isn't responding to touch or is freezing up, the reason could be there's debris lodged in the gap between the touch screen and the bezel.

And since that gap widens and narrows with cabin temperature, this issue can be intermittent, especially in cold weather.
