So, the brand new Toyota Highlander Hybrid makes very rude noises when braking at slow speed on uneven pavement. Sounds like a pop can crunching or something biological. I was thinking it was getting worse, so I took it to the dealer, and they couldn't figure it out.
Turns out that this is common, and it is the ABS happily grunting like a pig in sh*t. Some cars may be noisier than others, but the ABS now is so sensitive that it is detecting the uneven pavement. As well, it may be calibrating itself.
Some of the auto sites have an explanation, since this fills the Internet. So now, instead of always blaming the dog, I've got a new one: It's the car farting!
