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

The dashboard lights and controls may briefly flicker under hard acceleration after downshifting or when the engine is revved while the vehicle is stationary. The issue does not occur during normal driving, and all instrumentation continues to operate correctly. During periods of low electrical load (and especially when the battery is fully charged), the energy spike generated by the alternator due to the rapid increase in engine speed cannot be completely absorbed by the vehicle electrical system. This leads to a voltage increase that can cause some modules to initiate overvoltage protection. The condition is very brief and is considered normal.
