Hmmm.... I just recently started hearing a high pitched whine coming from somewhere. I'm not sure that I would consider it loud- just annoying and concerning. It seems (from the drivers perspective) to come from the right front (tire? ). Increased pitch as car excelerates and decreases as it slows down. And it does seem less prominent at higher speeds (but that may just be because it increases pitch beyond human 20,000 hz hearing range). It also seems to be more evident in cooler temperatures, in the morning commute, but not always. I didn't consider the tranny but maybe? 2018 chr xls NA version 30,000 miles... Anyone else??? Any thoughts on this issue?

Thank you! Maybe I'm not losing my mind... Sounds exactly like my issue... Anyone else experiencing this?

The dealer said it's something in the transmission and it's making the oil turn dark and that's not good

The transmission is replaced at the same time as the torque converter because there is no available remanufactured tranny for the CHR available through Toyota. They sell the tranny with no torque inserted, you order the torque separate it will always be like this until a reman comes available. Not sure what's failing, sounds like bearing inside the transmission. I'm a service manager in Canada, we've done 3 so far all with 90km-106km.
Not good. Built in Turkey! Gwan

I bought mine 2018 but it's a new 2019 model with 11,000 miles as of today. I know what you guys hearing especially on the driver's side. That humming sounds like a turbo, I will bring this up on my next service and it seems like pretty concerning to me.

Bought my daughter a 2018 in 2017 and at 91,000 miles recently developed humming noise which increased with speed. Dealer said needs transmission and quoted almost $9,000.
Took it to transmission place I use for my Chevy trucks and they found it was a carrier bearing (in the CVS transmission unit).
5 weeks later after parts shipments from Turkey and Hong Kong, car is running great. Paid $3,500 with 1 yr. 12,000 mile warranty.

That is quite scary? - I am considering having my tranny fluid flushed at 25k miles then. I just pushed 21k miles on my 2018 C-HR last week (only drive it on weekends or when I feel like it). My 2018 Rav4 is my daily shuttle.
