What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2007 Yamaha YP400, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

SCOOTER STALLS AND IS HARD TO START AGAIN. JUST PURCHASED THE SCOOTER LESS THAN 60 DAYS AGO AND IT IS UNRELIABLE AS WE HAVE BEEN STUCK TWICE IN ONE DAY. *TR

Fuel system

From owner reports, verbatim
IN HOT WEATHER, THE YAMAHA YP400 FAILS TO START, STALLS AT IDLE, AND INTERMITTENTLY CUTS FUEL AT HIGH SPEED. SYMPTOMS ARE NONEXISTENT UNTIL THE AIR TEMPERATURE EXCEEDS ABOUT 95 DEGREES F. SIMILAR PROBLEMS WITH THE FUEL PUMPS ARE FREQUENTLY DOCUMENTED WITH OWNERS OF MAJESTY YP400 MODELS AS WELL AS T-MAX XP500 AND ZUMA YW125, THE LAST OF WHICH WAS SUBJECT TO A RECALL OF ITS OWN. *TR
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
