Lexus Rx300 - Electrical Issue

[The Lexter]

Hi!

I am new to this forum and I am not sure where to post regarding this issue.

Yesterday morning, I tried to start the RX300 and it would not start the car. After a few tries, it started just fine. I was able to drive the RX300 around all day without starting issue.

Today, the RX300 had no issue with starting the car. However, I do notice a slight issue in the head lights and the lighting in the dashboard. I notice if I look closely at all the lights on the dashboard, the lights are flickering. It's kind of the car battery is not giving enough juice to make all the lights in the dashboard stay lit without the flickering. The dashboard lights are not going on and off, it just doing the low to high lighting.

I think because I was trying to start the car yesterday to many times that it effect all the lightings in the dashbaord.

Is there an easy fix or do I have to take it in to the dealer?

Thanks for any advice!!
