My RX 330 is working fine and has no warning lights on. Periodically, I hear one loud beep, a digital sound, almost like something you would hear on a phone or oven to alert you to something. It may happen once or twice a day. It is unrelated to the rear gate and no warning light goes on when it happens. I have no idea what this is. Thank you.

 

Does it happen when you reach a speed of say 5 mph?

I will have to focus on that but several have been at normal driving speeds

 

It happened today when first starting and had not even accelerated and out of nowhere, at 50 mph, it happened again. This was in 2 hours of driving. Thanks.
