What this means for you
Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.
Our severity reasoning: Rubric level 3 covers risk-of-harm where injury has not yet been reported: several auxiliary functions may not start correctly, but the vehicle retains control and propulsion and no incidents are recorded.
