A vehicle safety recall has a fixed path. The manufacturer, on its own or pushed by an NHTSA investigation, decides that a defect affects safety. It files a report with NHTSA within five working days, and NHTSA publishes it as a campaign with a number. The manufacturer then has to notify registered owners by first-class mail, normally within 60 days, and offer the repair at no cost.
Two things often surprise owners. First, the campaign can be public long before the letter arrives, because the letter waits for parts. Second, the letter goes to the address on the registration, so people who moved or bought the car used may never receive it. That is why looking a vehicle up is worth the two minutes.
What the three NHTSA texts mean
Summary says which vehicles are covered and what is wrong. Consequence says what can happen, in one or two sentences: this is the hazard. Remedy says what the dealer will do and when owner letters are expected. The remedy text can say that parts are not yet available; in that case an interim letter is sent and a second one follows.
After you find a campaign
Take the campaign number to the VIN check at nhtsa.gov/recalls or to a dealer of the brand. If the recall is open for your vehicle, book the repair; you do not need the letter. If you already paid for a repair that a later recall covers, manufacturers have a reimbursement procedure described in the owner letter.
