What this means for you
Our assessment, not the agency’s: severity 4/5 (Severe).
The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.
Our severity reasoning: Rubric level 4 covers structural vehicle defects: the source states the engine can stall, which is a total loss of propulsion, and the remedy includes installing a wire harness.
