NHTSA safety advisory

Park this vehicle outside

NHTSA advises parking it away from buildings and other vehicles until the repair is done — the risk exists even when the vehicle is switched off.

This is the agency’s own advisory, not our assessment. Contact the manufacturer or a dealer, and see the official NHTSA notice for the current guidance.

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: incorrect fasteners in the high voltage battery can produce a sudden total loss of drive power without warning.
