**Recalls** are mandatory repairs for safety or emissions issues identified by the manufacturer or NHTSA. If your car has a recall, you must get it fixed-it's the law and it's free.

**Technical Service Bulletins (TSBs)** are optional guidance from the manufacturer about known issues (performance, comfort, or durability problems). A TSB describes the fix, but getting it done is your choice, though warranty may cover parts and labor if it's needed during the warranty period.

**Key differences:**
Recalls affect safety or legal compliance-you'll receive a notice in the mail, and dealerships are required to perform the work at no cost. TSBs address common but non-safety issues; you might discover them online or through your dealer, and coverage depends on your warranty status.

**How to check:**
Visit NHTSA.gov and enter your VIN to see any active recalls. Ask Castle Cadillac McHenry's Service team about TSBs relevant to your car-they'll advise on recommended fixes and costs.

**Peace of mind:**
Don't ignore a recall notice. Call **(779) 265-4427** to schedule the free work. Our service team ensures your car is safe and compliant.
