U.S. auto safety regulators have opened an investigation into Rivian Automotive Inc. over the potential failure of a part that could lead drivers to lose control of their electric vehicles.

The National Highway Traffic Safety Administration said it received two complaints from Rivian owners describing separation of the so-called rear toe link, a suspension rod that connects the wheel hub to the vehicle chassis. Both incidents caused the EVs to “swerve across multiple lanes of traffic,” one of which resulted in a collision, the agency said in documents posted to its website.

The probe, known as a preliminary evaluation, covers about 115,000 of the company’s electric pickups and SUVs. Rivian didn’t immediately respond to a request for comment. 

Issues with the part previously led Rivian to recall of almost 20,000 vehicles earlier this year.
