Taking "an abundance of caution" to be on the safe side.
Tesla has announced it's recalling around 7,000 charging adapters according to Bloomberg after receiving reports from customers that they have been overheating. Specifically, the recall is for the NEMA 14-30 charging adapter used to connect a charging cable to a 240-volt outlet. Incidentally, Tesla stopped selling this adapter around two years ago, but it went back on sale earlier this year. As a precaution, the recall also affects the NEMA 10-30 and 6-50 chargers.
“In November 2016, we learned about two customers whose NEMA 14-30 charging adapters overheated,” Tesla said in an official statement. “These are the only two such incidents that we know of anywhere in the world and neither resulted in any injuries or property damage. However, out of an abundance of caution, we’re replacing NEMA 14-30, 10-30 and 6-50 adapters that were made years ago by our original supplier.” Tesla is advising Model S or X owners to use alternative methods to charge up their batteries, “such as with a Tesla Wall Connector or NEMA 14-50 adapter (if you have one), or by Supercharging.”
As for the 10-30 and 6-50, Tesla said that “they have some common elements with the NEMA 14-30,” so they are being recalled as a precaution. Since there have been no reports of these chargers overheating, you can still use them, however. The autocar maker expects the manufacturing and distribution of replacement chargers to take around three months. This isn’t the first time Tesla has issued a recall as a precaution. Earlier this year, the then-new Model X was recalled due to a faulty safety catch on the third-row seats. Overcautious, perhaps, but you can’t blame the manufacturer for wanting to protect its consumers.
