I explained campaigns in my post above (but I did not use the term "campaign"):
"In the past, Hyundai Motor America has had some TSB's that must be applied by the dealer for any car in their lot, or any customer car brought in for service for any other reason, but customers were not notified of the TSB."
The original TSB for transmission fluid change from DOT-3 to DOT-4 on early Genesis models was a campaign in the USA. It was later escalated to a recall, so that anyone who had not already had it done (for applicable
VIN's) got a notice in the mail for a recall. In the TSB PDF document I have for this, it specifically says "SERVICE CAMPAIGN."
There was also a TSB "AIRBAG CONTROL UNIT UPDATE - SERVICE CAMPAIGN" for the early Genesis airbags, that was not a recall:
IMPORTANT: DEALERS MUST PERFORM THIS CAMPAIGN ON ALL AFFECTED VEHICLES PRIOR TO CUSTOMER RETAIL DELIVERY AND WHENEVER AN AFFECTED VEHICLE IS IN THE SHOP FOR ANY MAINTENANCE OR REPAIR.
IMPORTANT: WHEN A VEHICLE ARRIVES AT THE SERVICE DEPARTMENT, ACCESS HYUNDAI MOTOR AMERICA'S "WARRANTY VEHICLE INFORMATION" SCREEN VIA WEBDCS TO IDENTIFY OPEN CAMPAIGNS.
But a TSB can be something not even related to a problem, such as a publication of factory paint codes of the Original Genesis models that was not found in the original documentation.
