What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2004 Yamaha Road Star Warrior, 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.

CONSUMER HAD BEEN WAITING ON PARTS FOR THE ROADSTAR FOR OVER 60 DAYS. DEALER STATED PARTS WERE STILL NOT AVAILABLE. TOUSLEY MOTOR SPORTS, 1400 E. COUNTY E. WHITELAKE , MN 55110 651-483-8296. *AK
TO WHOM IT MAY CONCERN: I AM NOT BEING TREATED FAIRLY BY THE YAMAHA CORPORATION. DUE TO THE RECALL STATUS OF MY 2003 ROADSTAR WARRIOR, THE YAMAHA CORPORATION IS COSTING ME MONEY AS MY MOTORCYCLE IS SITTING IN MY GARAGE WAITING FOR PARTS FOR THE RECALL. I NOW HAVE A MOTORCYCLE THAT I CANNOT RIDE BECAUSE OF THE RECALL, BUT MY PAYMENTS AND MY INSURANCE PAYMENTS ON THIS MOTORCYCLE KEEP COMING? I REALIZE WHEN DEALING WITH MACHINES OF THIS NATURE RECALLS CAN HAPPEN. THE RECALL ITSELF IS NOT THE REASON FOR THIS LETTER. THE ISSUE IS YAMAHA'S HANDLING OF THIS RECALL SITUATION. MY MOTORCYCLE HAS BEEN SITTING GOING ON TWO MONTHS BECAUSE OF THIS, AND MY YAMAHA DEALER HAS NO IDEA WHEN THE PARTS FOR YOUR RECALL WILL BE AVAILABALE. PLUS THE FACT THAT MY DEALER SAYS THERE ARE MANY MOTORCYCLES IN FRONT OF ME FOR THE RECALL, SO I HAVE NO IDEA WHEN MY MOTORCYCLE WILL BE DEEMED SAFE TO RIDE AGAIN. THEY HAVE NOT COMMUNICATED ANY INFORMATION TO ME OR TO MY DEALER AS TO WHEN THESE PARTS WILL BE AVAILABLE. YAMAHA'S CUSTOMER RELATION'S PEOPLE HAVE NO IDEA WHEN THE PARTS WILL BE AVAILABLE TO RETURN MY MOTORCYCLE TO A SAFE STATUS. THIS, IN MY OPINION, IS UNACCEPATABLE. EVERYDAY THAT MY MOTORCYCLE SITS UNUSABLE, I GET ANGRIER WITH THE YAMAHA CORPORATION. AT THIS POINT THERE IS NO WAY I WOULD PURCHASE ANOTHER YAMAHA PRODUCT, NOR WOULD I RECOMMEND A YAMAHA PRODUCT. I KNOW I AM A VERY SMALL SPECK ON THE TOTAL LIST OF OWNERS AND I FEEL THEY WILL NOT GIVE THIS LETTER A SECOND THOUGHT. BUT HEAR ME ON THIS, I WILL TELL A LOT OF FOLKS HOW I HAVE BEEN TREATED BY THE YAMAHA CORPORATION. ALSO, IF I AM NOT MISTAKEN, AFTER 30 DAYS OF THE VEHICLE NOT BEING REPAIRED, THERE IS GROUNDS FOR A LEMON LAW CASE.
