2006 MACK CHN
This model year
What the record shows
The 2006 Mack Chn is the 5th model year of a nameplate NHTSA records from 2002 to 2008.
The federal record holds 57 service bulletins for it.
Counts are reports, not rates. A complaint is something an owner chose to file; it is unverified and unadjusted for how many of these cars were sold, so the useful comparison is against other model years of the same car. Recalls and investigations carry more weight because a manufacturer or regulator acted on them.
Reading this report
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
