Example complaints

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

“Engine creates excessive heat making the motorcycle almost unbearable to ride. If sitting in traffic long the heat almost burns the undersides of both thighs. Neutral light comes on when changing gears, it is very distracting at night causing rider to take his eyes off the road. Dealer said all of this is normal. Engine heat problem can be fixed but it will be at the expense of the owner. Neutral light coming on is normal dealer said.”

“I am writing to you because I sent a complaint in the other day for someone and had several things wrong. This is a mistake that I am sorry for. I should have had the other person proof over what I was sending in. He has had eight harley's in his garage. The heat comes from the crossover under the seat. Also, in the component information, the only thing close to the problem description was what I checked. I understand if this should be deleted, the consumer, lane tucker will try to send it in himself.”

NHTSA complaint #10198607, filed 2007-08

“Purchased a 2007 ultra classic electra glide harley davidson on july 27. I had to return the bike this week and get my money back. This model has a heat problem which harley davidson and the dealers are aware of, they are selling these and not letting the consumer know about it. Once you are aware of this, they don't know how to solve it but they will change some things at your expense. I paid alot of money for this, not intending to go home and have to change it right away. The pipe under the seat gets so hot that it glows bright red. It burnt the passengers leg. …”

NHTSA complaint #10198521, filed 2007-08

“The contact owns a 2007 harley davidson Flhtc motorcycle. The contact stated his exhaust pipe turned red after overheating. The over heating is caused by the exhaust pipe and cylinder head. The dealer is waiting for approval from the regional manager to make the repairs. The failure mileage was 2,800.”

“Motor runs hot; found by using 89 grade, runs cooler and better. Also dealer uploaded new ignition program - harley issued a fix. Getting it done under warrenty. Gearbox noise: harley uses motor oil 20-50. Change it to full synthetic gear oil 85-120 (or something near). This quietens gear whine and makes it shift better. As a mechanical professor and on my 16th harley; never use 20-50 motor oil in any gearbox! Thats wrong in so many levels.”
