The National Highway Traffic Safety Administration is investigating how electric car maker Rivian services its vehicles’ rear suspension components, after receiving two reports from owners who lost control of their cars while driving.
The federal safety regulator’s Office of Defects Investigation (ODI) said on Thursday that both vehicles had been previously serviced, one of which had been in a collision before the work was done. According to the ODI, Rivian first realized in March 2025 that the rear toe link — a critical part of the suspension that helps keep the wheel straight — had a “sensitivity to service procedures,” causing the company to update how it handled the part during service and repairs.
