2007 YAMAHA YP400
This model year
What the record shows
The 2007 Yamaha Yp400 is the 3rd model year of a nameplate NHTSA records from 2005 to 2012.
The federal record holds 2 owner complaints, 1 investigation and 2 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.
