Service bulletin TT 91-15-07

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

Tech Tips (Customer concerns of their iPhone not connecting or having sporadic connections when using Apple CarPlay in the AppConnect environment): Ensure a cable certified by Apple is being used (a cable purchased from Apple or the cable that came with the phone). Non-certified or cables that are knotted, worn or extremely long will exhibit connectivity concerns. Cable adapters may also cause connectivity concerns.
