A few quick thoughts about the massive Dell battery recall:
The relatively new Restatement (Third) of Torts: Product Liability proposes some modifications of the common law duty to warn after a sale (as opposed to a duty to warn — i.e., on the packaging — before a sale).
Of course, a manufacturer remains strictly liable for any damages proximately caused by a manufacturing defect before a post-sale warning or recall is announced. Under the Restatement (Third), Section 11, there is still never a “duty to recall,” unless imposed by the government.
Previously, the determination of whether there was a “duty to warn after the sale” was no different than any other test for duty: Did the benefits of a post-sale warning outweigh the costs?
