Rivian has announced a voluntary recall for 12,212 vehicles to fix an improperly tightened fastener that connects the front upper control arm and steering knuckle.

In a letter to owners that InsideEVs senior editor and R1T owner Tom Moloughney also received, Rivian CEO RJ Scaringe said affected vehicles include certain 2022 model year R1T pickups and R1S SUVs built during a 13-month period and EDV vans produced between December 10, 2021 and September 27, 2022.

That’s pretty much all the vehicles Rivian has delivered so far, although the safety recall report submitted to NHTSA notes that only 1 percent of the total number is estimated to actually have the defect.
