Whinning noise when decelarate

Post by chr-lisbon » Fri Nov 29, 2019 7:33 am

Hi, anyone notice some high pitch noise while decelerate the chr hybrid while moving.

Its only noticeable from driver side and when the car is moving.
No sound when the car is stoped.

The sound start recently and its similar to some turbo whizzling accelerating in diesel car

A very high whisle sound is normal for a Toyota hybrid when its running on EV. Comes from the converter. ;)
Some people dont even hear it..

Thats sure possible.. i dont notice it all the time too. Just sometimes when running in town on EV or when slowing down to a traffic light.
When you push throttle and engine comes up its gone.. but when driving/rolling out on EV its there again.
Sometimes its more noticable as usual. Why? I did ask the system but got no answer.. :mrgreen:

Also the green EV light does sometimes not come up when i expect to.. its running on EV but there is no green EV light..
Mine has 41.000km on it now and i stopped wondering why.. My C-HR system knows it better i suppose. :roll: :D

The MPG is still great and it runs like new. Nothing left there for me as just enjoy my ride. ;)
