Hi Tim. I just recently purchased a used 2018 Toyota CHR XLE from a dealer in the USVI in December 2020. And I just noticed that same damn annoying humming sound in the rear of the vehicle. I was sitting in the driver's seat for awhile then fell asleep. Woke up and there it was that constant "humming" in the rear.
