Tesla to Upgrade Adapter on Reports of Garage Overheating

Tesla Motors Inc., which is under investigation by U.S. regulators over fires in its Model S sedan after battery punctures, will upgrade wall-charger adapters following reports of overheating in garages.

The charger connectors, which tether Tesla-issued cables to wall outlets, will be mailed out in the next two weeks, Chief Executive Officer Elon Musk said in an interview today. The replacements will be treated as a recall, though owners won’t be required to travel to service centers. Overheating can stem from inadequate household wiring, he said.
