Tesla will voluntarily recall about 7,000 electric-car charging adapters after two reports of overheating resulting in melted plastic on the adapters.
The adapters are accessory items sold by Tesla online, but were manufactured by an outside supplier.
They haven't been sold in six months, according to Tesla.

Tesla's disclosure of the adapter overheating issue came in the form of an e-mail to customers, found by Bloomberg.
The e-mail said that two customers had reported overheating in November, and that no damage other than the melted plastic on the adapters was reported.
Tesla said it had notified U.S. regulators of its plans for a voluntary recall of the adapters.

The recall is reportedly limited to the U.S., and so does not affect Tesla customers in other countries.

Tesla will begin shipping new adapters to affected customers in the next few weeks, and recommends that customers should avoid using them in the meantime.
The company will also replace NEMA 10-30 and 6-50 adapters, which have a similar design.

No customers have reported overheating in either of those adapters, and owners may continue to use them, the company said.

This is the fifth recall for Tesla since the first Model S sedans were delivered to customers in June 2012, but the first for an accessory.
Last year, Tesla recalled every Model S on the road at the time to check that their seat belts were properly connected, after a single report of an improperly-fastened seat-belt mechanism.
In April, Tesla recalled 2,700 Model X crossovers to replace third-row seat backs, after a recliner unexpectedly slipped during seat-strength tests.
