2021 Highlander Whistling Noise

The all-new 2021 Highlander is making a whistling noise that has some drivers on edge. The problem seems to be most prevalent when the vehicle is first started, but it can also happen while driving. It’s unclear what is causing the noise, but it’s certainly not normal and Toyota needs to figure out a fix quickly.

In the meantime, if you’re driving a Highlander and hearing a whistling noise, you may want to bring it in to your dealer for inspection.

If you own a 2021 Highlander, you may have noticed a strange whistling noise coming from the vehicle. This is a known issue with the Highlander and is being addressed by Toyota. In the meantime, there are a few things you can do to help reduce the noise.

First, make sure that all of the windows and sunroof are closed tightly. The whistling noise is caused by air leaks and so sealing up any openings will help to reduce the noise. You can also try opening or closing the vents in the vehicle to see if that makes a difference.

If you’re still having trouble with the noise, contact your local Toyota dealer for assistance. They may be able to provide additional tips or help schedule an appointment for repairs.

-What is the Whistling Noise on the 2021 Highlander

If you’re the owner of a 2021 Toyota Highlander, you may have noticed a strange whistling noise coming from your vehicle. While this may be alarming at first, there’s no need to worry – the noise is simply caused by the car’s new design.

The 2021 Highlander features what’s called an Active Noise Control system.

This system uses sensors to detect unwanted sounds inside the cabin and then creates opposing sound waves to cancel them out. In most cases, it does a pretty good job of making the cabin nice and quiet. However, some people have reported hearing a faint whistling noise when driving at high speeds with the windows up.

This is likely due to the fact that Active Noise Control can’t completely eliminate all sounds – it can only reduce them. So, if there’s already a lot of noise coming from outside the car (such as wind), the system may not be able to completely cancel it out. If you’re bothered by the whistling noise on your Highlander, there are a few things you can try.

First, make sure that all four windows are fully closed. If that doesn’t help, try opening one or two windows slightly to let in some outside air – this can help reduce wind noise and make it less noticeable. Finally, if neither of these solutions work for you, you can always turn off Active Noise Control entirely (though this will also disable other features like Engine Sound Enhancements).

So there you have it – now you know why your Highlander is making that strange whistling noise!

Conclusion

If you’re the owner of a 2021 Highlander, you might have noticed a whistling noise when driving. This is caused by the design of the new model and is not a cause for concern. However, if the noise is bothersome, Toyota has released a software update that should fix the issue.
