What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt. Owners’ complaints are counted on each vehicle’s page.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • How many have been returned or fixed isn’t in the notice.
