Recalls should be taken care of by your dealer. [i]Generally[/i] speaking there is no expiration on a recall, but some do not have to be performed at the manufacturers cost after certain time and mileage limits. Check with your dealer to see if there are any outstanding recalls on your vehicle that need to be delt with. Normally all they need is the VIN to run a check.
Service bulletins address known problems with a known solution. They do not imply any responsibility on the part of the dealer or manufacturer to fix your vehicle. Only that they know of a problem and a solution. They are strictly information. No TSB might apply to your vehicle if you don't have any problem. You might develope a problem later when your vehicle is long out of warranty that a TSB applies to.
