Tesla issued a recall on Tuesday on a power adapter that could have a defect which leads to shorting and even fire in some cases. The recall says that the NEMA 14-50 adapters used to charge Model S vehicles could exhibit higher than normal resistance when subject to corrosion, damage or fluctuating outputs of electrical sockets. When the adapters encounter resistance, they heat up, which could lead to melting in the adapter’s casing, the socket or the cord. This, in turn, could result in electrical arcing and fire. Interestingly, Tesla says that it will be able to ‘repair’ the charging receptacle with an over-the-air software update. Most likely this will regulate voltage in a more aggressive manner to prevent the issues. In addition, it’s engineering a new 14-50 adapter that will contain a thermal fuse, which will add in a physical cutoff if the charger gets too hot.
