Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“After 15 minutes in stop and go traffic the cycle overheated (the temp gauge was in the red area). The consumer pulled to the side and the cooling fan could not be heard.”

NHTSA complaint #10025092, filed 2003-06, 600 miles

“Motorcycle has a tendency to overheat when driven slow, ie., in traffic or when going through a construction area. This is very dangerous, as it takes away my concentration to drive, since I have to keep a constant eye on the temp gauge. This happened to me twice so far, once in a traffic jam, and the other in a construction zone. There is also the very real possibilty of loosing coolant in this overheating situation, and getting it on the rear tire, which would result in loosing controi of the bike. …”

NHTSA complaint #767570, filed 2002-09

“The design of the Honda goldwing cooling system fails miserably in heavy, slow moving traffic conditions found at construction sites, metro areas, parades, etc. In my cases as the engine temp rose to the upper limits I was hemmed in by traffic and unable to pull over to allow the engine to cool. Serious personal hazards are presented by this design flaw: 1) being struck by other vehicles while sitting along the side of the road. 2) many side road surfaces not suitable for pulling off onto. 3) many roads not having a shoulder. …”

“Recall notice on the frame weld of motorcycle. Dealership welded only about 45 percent of the frame instead of 100 percent. Recall#03v350000 the consumer also stated the dealer sold him the motorcycle knowing that it had an overheating problem and eventually a recall was issued.”

NHTSA complaint #10051661, filed 2003-12

“Engine will overheat during sustained low-speed operation, such as slow-moving traffic in a construction zone. Temperature guage needle will move all the way to the red mark, unless the motorcycle is either stopped or speeded up. Eventually, coolant is expelled onto the ground directly in front of the rear tire and onto the tire, due to the location of the coolant overflow tank and its overflow hose. Ts”
