After offering its customers free NACS adapters for Tesla’s Superchargers, Ford is telling its customers to stop using them, according to a service bulletin spotted by InsideEVs. The reason cited is a “potential issue” that could reduce charging speeds over time and even cause charging port damage, the company wrote.
The automaker will send a replacement adapter “in the coming weeks” and requires customers to send back the existing adapter, both at no cost. “It is imperative that we receive all adapters affected to reduce the risk of potential vehicle damage,” it added.
After signing an EV-charging pact with Tesla in May 2023, Ford EV owners in Canada and the US got a green light to use Superchargers earlier this year. The original deadline for a free adapter was June 2024, but after multiple delays due to supplier issues, the deadline was extended until September 30, and may be further put off due to this latest issue.
The adapters convert North American standard CCS ports used on Ford EVs to Tesla’s proprietary NACS cables. Other companies (Nissan, Rivian, GM, Subaru and many others) that cut deals with Tesla offered similar adapters, though many will permanently adopt the NACS standard for future vehicles. Ford itself plans to make the switch in 2025.
Creating a NACS adapter isn’t just a matter of changing the pins around, as the latest V4 Superchargers are rated for 250 kW and 615 A — enough to power multiple homes. Earlier this year, Tesla sued the supplier of a cheap NACS adapter, saying it could lead to “catastrophic” injuries.
