Rivian has issued a recall for its R2 SUV after the company discovered that fasteners on its high-voltage battery pack might not be properly tightened, which can cause a loss of power while driving.

The company says only around 14 vehicles may have been affected, and that it will repair or replace damaged components on customer vehicles as needed. Rivian told TechCrunch that all of the affected vehicles are at service centers “being inspected to properly torque the fastener or replace damaged components at no cost to customers.”

This is the second recall Rivian has issued for the R2, which started shipping to customers this year. It’s an all-important vehicle for the company, as it’s the first Rivian EV meant for a mass market and is supposed to help it reach profitability for the first time. The first R2 recall, issued last month, had to do with the visibility of the backup camera and was addressed with a software update.
