This time the rider is placed in the middle of traffic, potentially causing a crash or risk of injury.On October 9, 2020, ODI received Honda?s Information Request (IR) response and learned that Honda was aware of 36 complaints, 87 field reports and 83 warranty claims of stalling related to clogged fuel filters. There were no claims of crashes or property damage associated with the alleged defect on the subject…
