loud noise when in reverse

[annbrogan]

I have been told that the noise coming from the front of the car is to let the driver know when you are in reverse.   It is a safety feature because the car is so quiet.  I hear the noise once every 25 times I drive the car.  Also, could Lexus have come up with a less obnoxious sound?

I have a 2020 Lexus 250h

Any thoughts?

Sounds plausible I guess

Could be an issue with the brakes. It's one of the causes of why a car is making noise when reversing.

Have the wheels/hubs/brakes inspected...It is not normal.

I just bought a 2021 ES Hybrid. Mine makes the same sound only when I put it in reverse. I dont mind it..

Is this confirmed by a Lexus dealer ? Find the truth first. Thanks

Have it checked by a mechanic just to be sure.

It's a feature to alert blind or sight impaired folks that a vehicle is moving possibly toward them similar to a back up alarm of a dump truck on a contruction site. 

It's something started in Japan in 2010 and the US in 2011. There will likely come a day where electric vehicles are required to produce a certain amount of noise to notify pedestrians with vision issues of automobiles approaching them.

Loud noise when reversing is also an indication of worn out brake pads.
