Recall 21V311 affects 261 2019-2021 Arcimoto Fuv, Deliverator, Rapid Responder, and Roadster vehicles for an inverter software defect. Repair is free at Arcimoto.
Arcimoto is recalling 261 2019-2021 Fuv, Deliverator, Rapid Responder, and Roadster vehicles under recall 21V311 because a software error can cause inverter communication to time out and trigger an unexpected battery shutdown. A sudden loss of power raises the risk of a crash, and Arcimoto dealers will update the software free of charge.

What's wrong?
Each affected Arcimoto vehicle runs on two electric motor inverters that talk to each other over an internal data network called CAN. The inverters trade short messages many times per second to coordinate power delivery to the wheels. As long as both inverters keep sending and receiving those messages on time, the traction system stays energized and the vehicle drives normally.
On these 2019-2021 Arcimoto FUV, Deliverator, Rapid Responder, and Roadster vehicles, the second inverter can generate more communication traffic than its short-term memory can hold before sending it on. Frames get dropped. The receiving inverter is not built to tolerate missing frames or to keep driving on a single inverter, so it triggers a fault, opens the traction contactor, and shuts the battery off to the drive system. The vehicle loses propulsion without warning.
There is no warning sign before failure. The shutdown happens suddenly, and the driver only notices once power to the wheels is gone.
Who's affected?
Spans four Arcimoto models (Fuv, Deliverator, Rapid Responder, Roadster) across the 2019, 2020, and 2021 model years, all sharing the same inverter and electrical system software.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
A sudden battery shutdown cuts power without warning, which raises the risk of a crash. There is no warning sign before it happens, so schedule the repair soon and watch for any unusual electrical behavior in the meantime. If your vehicle was already repaired under Recall 19V834, it needs to return for the updated fix. Repair is free at any franchised Arcimoto dealer.
What should I do?
- Check your VIN to confirm your 2019-2021 Arcimoto FUV, Deliverator, Rapid Responder, or Roadster is included in this recall.
- Contact a franchised Arcimoto service center to schedule the free inverter firmware reprogramming that fixes the inverter communication timeout.
- Call Arcimoto customer service at 1-541-683-6293 and reference recall number 21V311 when you call.
- Return for this remedy even if your vehicle was previously repaired under recall 19V834, because that earlier fix is superseded.
- Drive cautiously until the software update is complete, since a battery shutdown causes an immediate loss of power.
What happens at the repair
At the dealer, an Arcimoto service technician reprograms the inverter firmware to correct the communication timeout between inverters. The update is free under the recall. If your vehicle was previously repaired under Recall 19V834, it needs to return for this new remedy. Owners who paid out of pocket for related repairs before the recall notice can request reimbursement under Arcimoto's standard reimbursement plan. Bring your receipts and any related repair paperwork to the service visit, or contact Arcimoto customer service at 1-541-683-6293 to confirm what documentation is needed before you arrive.

Frequently asked questions
What is recall 21V311?
Recall 21V311 covers 261 2019-2021 Arcimoto FUV, 2020 Deliverator, 2021 Rapid Responder, and 2020-2021 Roadster vehicles with a software error that can time out communication between inverters and trigger an unexpected battery shutdown. An Arcimoto service technician will reprogram the inverter firmware for free.
What should I do if my 2019-2021 Arcimoto FUV, Deliverator, Rapid Responder, or Roadster is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 21V311. If it is, contact Arcimoto customer service at 1-541-683-6293 to schedule the inverter firmware reprogramming. Reference recall number 21V311 when you call. The repair is free, even if your vehicle was previously serviced under recall 19V834.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to fix the defect at no cost, and an Arcimoto service technician will reprogram the inverter firmware free of charge. Vehicles already repaired under the earlier recall 19V834 must return for this new remedy, also at no cost.
What is the safety risk?
A battery shutdown causes an immediate loss of power, increasing the risk of a crash. Because the shutdown is unexpected, it can happen while driving and leave the vehicle without propulsion in traffic. The firmware reprogramming corrects the inverter communication error that triggers the shutdown.
What if I already had recall 19V834 performed on my Arcimoto?
You still need the new repair. Arcimoto's notice states that vehicles previously repaired under recall 19V834 must return for the updated inverter firmware reprogramming under recall 21V311. Contact Arcimoto customer service at 1-541-683-6293 to schedule the service. The repair is free.
