A reader named Doug had a problem with the panoramic moonroof on his Limited Platinum Highlander. Fortunately, the dealer figured it out:
“I had an issue with a rattle in the panoramic moonroof. After two attempts, they found a Toyota note in the system about this issue related to loose screws in the roof. They found this issue with my vehicle and corrected the rattle. Makes me concerned with QA.”
Interesting. We have an XLE, so no panoramic moonroof. I’m not sure if this “note in the system” was a TSB or if it was something less formal, but… If your moonroof is rattling, a loose screw could be the culprit.
