NHTSA a government agency can only require a recall if a failure will affect safety, emissions, fuel economy, or compliance with some other regulation or law. Manufacturers can voluntarily recall cars for problems that do not affect these, though. Recalls often apply to only some cars of a specific model year, rather than all of them. You should receive a letter from the manufacturer if your car has been recalled.

You can also check with the dealer, which will know which if any recalls pertain to your car. The primary purpose of TSBs is to inform dealers about known problems with a car and how to fix them. They are not the same as recalls.

As with recalls, TSBs often only apply to some cars, not the entire model year. Dealers often will not provide a preventive repair just because a problem described in a TSB might happen to your car.

Even if there are symptoms, a manufacturer doesn't have to pick up the cost of a TSB repair if the car is out of warranty, though sometimes they do.
