REUTERS/Mike BlakeMay 28 (Reuters) - The U.S. National Highway Traffic Safety Administration said on Thursday it has opened a preliminary probe into 114,922 Rivian vehicles over an issue with the rear toe link.The issue relates to the company's R1S and R1T electric vehicles.The agency's office of defects investigation received two vehicle owner questionnaires reporting that the left rear toe link separates while driving, causing vehicles to swerve across multiple lanes of traffic, NHTSA said.AdvertisementAdvertisementOne incident resulted in a collision with an adjacent vehicle and roadside barrier, NHTSA said.The probe will assess the sensitivity of the rear toe link joint to foreseeable road and service conditions and evaluate Rivian's current toe link repair procedure, among other steps.Rivian did not immediately respond to a Reuters request for comment.The company had in January recalled nearly 20,000 previously serviced R1S and R1T electric vehicles in the U.S., citing incorrectly assembled rear toe link.The automaker will replace the rear toe‑link bolts free of charge, the regulator had said then.(Reporting by Zaheer Kachwala in Bengaluru; Editing by Leroy Leo)
