I have read so many comments and reports on the forum and Ridgeline owner Facebook group about this problem and finally it happened to me. This high pressure fuel pump chirping noise is very annoying. At least there is a TSB about this issue but I've heard not all dealers will honor the TSB and fix it which is to replace the high pressure fuel pump and associated parts. The first complaints were from the pilots owner and since Ridgeline is practically the same under the hood we share this issue too.
