Ford F-150 Lightning and Mach-e drivers may have to wait a little longer to plug into Tesla’s Supercharger network. After several had already received their NACS adapters, Ford emailed many to say it was replacing the unit. In the meantime, the company doesn’t recommend using the current one.

Ford replacing some NACS adapters over potential issue

Last May, Ford CEO Jim Farley joined Elon Musk on X to announce a partnership that would allow Ford EV drivers to access Tesla’s vast Supercharger network.

Ford was the first, with nearly every major OEM revealing similar plans shortly after. Although Ford’s electric models won’t have a built-in NACS port until next year, Ford said it would send drivers an adapter to gain quicker access.

After opening reservations for the adapter in January, Ford initially said drivers could order one through June 30. The deadline was moved to August 31, earlier this summer.

Now, Ford already is planning on replacing some of the NACS adapters that were sent out to owners.

Several Ford F-150 Lightning and Mustang Mach-E drivers are receiving emails saying, “As a part of ongoing testing, your adapter has been identified by Ford to have a potential issue that may result in reduced charging speeds over time, and in some cases, charge port damage.”

The email adds, “Ford does not recommend using the adapter initially supplied to you with any vehicle from this time on, and we will be sending you a replacement.”

While you wait on the replacement, Ford drivers can check FordPass or other public charging apps to find other options.

As part of its new “Ford Power Promise,” the company is giving new EV buyers a free Level 2 home charger and covering the cost of standard installation.

Ford says its new program is designed to make it easier than ever to go electric while closing the gap between perceptions about EVs and the reality. According to Ford, most people don’t realize the true benefits of driving an EV, such as waking up to a full charge every day.
