Various Electronics Problems that are there 98% of time

My v will be 3 years old soon, and it has developed various electronics problem.

1. Night time GPS screen got so dark - now use Day time all the time as I learned that this was the prevailing issue.

2. The dealer swapped the GPS screen trying to fix the GPS screen issue. After the swap, I cannot switch back and forth between the map screen and audio screen. Once I am using the map, it just is a matter of luck to go back to the audio screen.

3. After using the windshield washer, the wipers do not come out automatically.

Now here is my problem - the problem 2 and 3 occur 98% of times - not 100% of times. When I took the car to the dealer, it was one of the 2% time and they could move back and force between the map and audio screen. Despite the fact that I showed them the video, the dealer said that they could not do anything as they could not duplicate the problem.

I am going to bring the car in again and tell them of the new problem 3. It was also videotaped.

Any suggestion what I would do these problems that are not there 100%?

Thanks!

 

Yes, I know the dimmer, and it is not the issue. It seems many people share the same problem. But the dealer thinks it is perfectly OK even if I could not see anything just the mark of your car.

To go back to the audio screen is just a mere luck. I could press the audio button 100 times and it would not go back to the audio screen. Turn off the engine, and turn the car back on next day, still stuck at the map screen. And all the sudden at no particular moment, when I press the audio button, it goes back to the audio.

The windshield washer issue is new. Again it works sometimes and does not work other times. Very frustrating.

 

I took the car in for 25000 mile service. We had the interesting argument with the rep at the desk - he claims that the wiper SHOULD NOT come on automatically upon use of windshield cleaner. I told him that all the cars that we had owned had that features. And then he said "maybe not your model."

I told him that I had the feature on my Prius from the start, and then suddenly the windshield wipers stopped coming in when using the windshield wipers. Really....
