What's wrong?
The driveshaft on the 2021-2022 Xos RM01, SV05, and SA01 carries motor power to the wheels. At the electronic parking brake, bolts hold the parking brake rotor to the driveshaft so the driveline stays locked together and the parking brake can hold the vehicle when applied. Those bolts need the correct torque, meaning the right tightening force, to keep the joint clamped under load.
On affected vehicles, Xos used a torque specification that was too low for this connection. The issue came from an engineering oversight that misidentified the tightening value for the bolts. With too little clamping force, the bolts can loosen, and the driveshaft can separate from the electronic parking brake connection.
There is no warning sign before failure. An owner should not count on a sound, vibration, or dashboard message to appear before the driveshaft connection fails.

What's the safety risk?
Loose driveshaft bolts can let the driveshaft separate, causing loss of drive power and increasing the risk of a crash. Schedule the repair soon. Until it is done, treat any sudden loss of power as a reason to pull over safely and call for help. Repair is free at any franchised Xos dealer.
What should I do?
- Check your VIN to confirm your 2021-2022 Xos RM01, SV05, or SA01 is included in this recall.
- Contact a franchised Xos dealer to schedule the free bolt and hardware replacement that secures the electronic parking brake rotor to the driveshaft.
- Bring the recall notice if Xos sent one. If not, reference recall number 23V145 and Xos recall REC 002-23 when you call.
- Drive cautiously until the repair is complete, and stop in a safe place if the vehicle loses drive power.
What happens at the repair
At the dealer, a Xos technician replaces the bolts and related hardware that connect the electronic parking brake rotor to the driveshaft. The recall repair is free, including parts and labor. Out-of-pocket repairs already paid are handled through the manufacturer's warranty, not through a separate reimbursement program, because the affected vehicles remain under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
