I have a new video showing where to find the origin of rattles and I included a mpg update. I have a few other videos about mpg on the Prius on that channel Here is the link to the rattle video youtu.be/9T9JcGyeJpE
Yeah, with the windows rolled down on my Gen 4, I get a rhythmic reverberating boom possibly from the passenger seat belt buckle too.
Nice video, Jimmy!! BTW, the link in the first post still gives a 404 error. But the embed in @davecook89t's post worked fine.
Thanks and thanks for watching. I just corrected it again then signed out and tried it and it works now.
Keep up the great work, sir! I enjoy all your videos. And that's a fine looking Silver Prius you have.
