Both are manufacturer-issued instructions to dealers, but recalls and technical service bulletins (TSBs) serve different purposes and have different urgency.

## Recalls

A recall is a mandatory fix for a safety or emissions defect affecting multiple vehicles. The NHTSA oversees recalls; manufacturers must notify owners and fix the problem for **free** regardless of warranty status or mileage. You should respond promptly-safety is the point.

## TSBs (Technical Service Bulletins)

A TSB is guidance to dealers on how to fix a known issue that doesn't rise to recall severity. They're voluntary for owners and may not be free after the warranty expires. TSBs cover things like noise, vibration, or performance quirks that aren't safety risks.

## How to Check

Visit NHTSA.gov and search your vehicle's year, make, and model to see open recalls. Castle Chevrolet Service can look up any TSBs relevant to your car.

## What to Do

If you receive a recall notice, **contact Castle Chevrolet Service at (630) 279-5200** to schedule a free repair. Ask about TSBs during your regular maintenance visits-your service advisor will recommend fixes if they apply to your vehicle.
