Service bulletin A551536 2040628-

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

Customer complains that the trunk lid open warning is displayed in the instrument cluster even though the trunk is closed. No DTCs are stored. In certain driving conditions, a reverse current may be sent from the halogen trunk light if it is missing its protective diode. Because the trunk light and the trunk lock switch are on the same circuit, the reverse current falsely triggers the trunk open warning. Unlike halogen trunk lights, LED trunk lights are not produced with protective diodes.
