Service bulletin T-TT-0496-18
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.

NHTSA's summary
TT: Vehicles may experience a MIL ON condition exhibiting codes P314A and/or P0C73 with evidence of water (corrosion) at the A9 inverter water pump connector. This condition may be caused by vehicles being equipped with an aftermarket windshield assembly with a poorly sealed or damaged deicer harness. Water can enter in through deicer harness, wick down to the common shared ground junction A72 and then wick from the A72 ground connector to inverter water pump connecter.
