Getting an unexpected letter in the mail about your vehicle—or finding out your car has a “known issue” at the mechanic—can instantly make your stomach drop. Is my car safe to drive? How much is this going to cost me?

Automakers regularly issue notices to dealerships to address vehicle issues, but not all notices are created equal. The three most common terms you will hear at the service desk are Safety Recalls, Technical Service Bulletins (TSBs), and Special Coverages.

While they all involve fixing your car, they differ drastically in terms of urgency, safety, and most importantly—who foots the bill.

1. Customer Safety Recalls: Mandatory and Free

A safety recall is issued when a manufacturer or the National Highway Traffic Safety Administration (NHTSA) determines that a vehicle model has a safety-related defect. This could involve a malfunctioning airbag, faulty steering components, or a fire risk.

What you need to know:

  • You will be notified directly: Automakers are legally required to mail a letter to the registered owner.
  • The repair is 100% free: The manufacturer covers the entire cost of the repair at an authorized dealership, regardless of your car’s age or mileage.
  • Urgency: High. You should schedule a service appointment immediately.

2. Technical Service Bulletins (TSBs): Helpful but Optional

This is where many drivers get confused. A Technical Service Bulletin (TSB) is essentially an internal memo sent from the manufacturer to dealership mechanics. It provides standardized instructions on how to fix common, non-safety-related quirks (like a squeaky suspension or a glitchy radio touchscreen).

What you need to know:

  • You won’t get a letter: TSBs are reference guides for mechanics, not customer alerts.
  • They are NOT free out-of-warranty: If your car is still under its factory warranty, a TSB repair is free. If your warranty has expired, you are responsible for the repair bill, just like any standard maintenance. The TSB simply helps our technicians diagnose and fix the problem faster.
  • Urgency: Low. Fix it only if the issue bothers you.

3. Special Coverage Adjustments: The Middle Ground

What happens if an automaker notices a non-safety part is failing early, but it doesn’t qualify as a recall? They issue a Special Coverage Adjustment (sometimes called a Customer Satisfaction Program).

This acts as a targeted warranty extension for one specific problem. For example, Chevy might extend the warranty on a specific sensor to 10 years or 120,000 miles.

What you need to know:

  • Coverage applies conditionally: Unlike a recall, you only get this fixed if your car actually exhibits the specific problem. If the part is working fine, no action is taken.
  • It is free (within the extended window): If you experience the issue within the new time/mileage limit, the dealership fixes it for free, even if your standard bumper-to-bumper warranty expired years ago.
