A TSB is not a recall. It's a Technical Service Bulletin. Or, a Service Bulletin that's technical in nature. It may be related to a recall, but that's because of the technical details.There were 300 Ascent TSB's?? Sheesh. Is that way above average?
In simpler terms, consider it a topic specific training guide. That's all it is.
So, the more the merrier.
NHTSA has many of them.Is there a website that has all of the Ascent TSB's in one place?
STIS has all of them, in their latest and most up to date form.
