NHTSA Probes Rivian Over Lane-Departure Risk

Why It Matters

The NHTSA probe highlights risks in ADAS and component integration that tech teams must consider when designing, validating, and monitoring vehicle software and hardware. Product, safety, and QA engineers need to address regulatory scrutiny, root-cause traceability, and field remedy processes as EV production scales.

Latest Changes

• NHTSA opened an investigation covering nearly 115,000 Rivian vehicles over unintended lane departures
