Apple Inc. has been sued in federal courts in Illinois and California for allegedly knowingly selling iPhone 7 and 7 plus models with an audio chip defect, called the “Audio IC Defect” or “Loop Disease” by consumers, which causes an array of operational issues.

The bug gums up handset audio functions, grays out speaker buttons during calls, and degrades microphone fidelity.  And if that’s not enough it can kill Siri’s voice command capabilities.

The plaintiffs accuse Apple of actively concealing the Audio IC Defect while advertising the iPhone 7 as “the best iPhone we ever made.”

The plaintiffs claim that when they first experienced operational problems Apple didn’t offer complimentary repairs.

The suits allege breach of warranty and violation of California and Illinois consumer protection laws. Plaintiffs seek class certification, damages, attorneys’ fees, and injunctive relief. In Illinois, the plaintiffs may also try to force Apple to repair, recall, and/or replace current defective iPhone 7s in the United States and notify all purchasers of the Loop Disease.

Evidence shows “Apple’s internal acknowledgement and subsequent discontinuation of their out-of-warranty repairs without public announcement of the Audio IC Defect amounts to misrepresentation and concealment of the Audio IC Defect,”  the California complaint in Casillas v. Apple reads.
