The check runs against NHTSA's live database and tells you which campaigns list your vehicle. 9 campaigns currently list the 2008 Mack Gu; your car may already have been repaired under some of them.
Is the recall repair free?
Yes. Under federal law, manufacturers must fix safety recalls at no charge for vehicles up to 15 years old from the date of sale to the first owner. Contact any authorised Mack dealer with your VIN and the NHTSA campaign number (for example 07V098000).
