Example complaints

“While waiting at a red light. I smelled coolant which I assume was coming from the car in front of me. I continued to smell coolant whenever I came to a stop. I arrived home and checked for any visible leaks and did not find any. A week later when I was washing my m109r I noticed coolant residue on the starter. I called to make an appointment to have the bike check. I was informed by the dealer that they have a lot of m109rs coming in for coolant leaks. Why is this not a recall?”
NHTSA complaint #10205080, filed 2007-10, 2,700 miles“I have been smelling coolant for the past few weeks on my motorcycle. I really never thought much about it just thought it was something else or another vehicle since my bike is only one year old. I checked the overflow tank today and it is empty. I got online and looked up my specific bike and found many owners having the same problem and having to pay to get this fixed themselves or fixing it themselves. I think this is too premature for a problem of this type and should be recalled. Other owners have gas leaks listed as well. …”
