- The fastener connects the vehicles' front upper control arm and the steering knuckle, and there have been two reports of the fastener coming loose, according to documents filed with NHTSA.EV startup Rivian, responding to reports of an insufficiently torqued fastener that could cause excessive noise, vibration, and harshness, will recall more than 12,000 R1S, R1T, and EDV commercial vehicles built between December 2021 and the end of September 2022.The company called it a potential safety issue in its filings with the National Highway Traffic Safety Administration (NHTSA) and said it will notify owners to arrange the fix by November 24.Rivian reported that its engineering staff reviewed one problematic vehicle on August 13 and listed six additional reports of problems with the fastener received by the end of September, including two where the steering knuckle "had become loose or separated."Other recalls for the new products have included one for an airbag sensor that did not work to deactivate the safety system if an infant seat was in the front passenger position, and another for an improperly attached seatbelt anchor."
