BRP is NOT a publicly traded company, leaving few options to apply leverage to the company to take action. In the US the NHTSA regulates motor vehicle recalls. THe agency's website states:
NHTSA conducts defect investigations and administers safety recalls to support its mission to improve safety on our nation's highways. NHTSA is authorized to order manufacturers to recall and repair vehicles or items of motor vehicle equipment when investigations indicate they contain serious safety defects in their design, construction, or performance. NHTSA also monitors the adequacy of manufacturers' recall campaigns.
Before initiating an investigation, NHTSA carefully reviews the body of consumer complaints and other available data to determine whether a defect trend may exist. [emphasis added] The interpretation is that the agency is more likely to take action if they receive alot of complaints about the same issue. I believe that if everyone on this thread filed a complaint with the NHTSA there's a good chance there would be a recall and everyone's turn signals would be replaced; at least that's my hope. If you are interested in filing a consumer complaint with the NHTSA, the link is below. I filed mine today.
