I have a 2001 GS430 with Navagation and Levinson. Here's the issue my warranty expires at the end of this month. If I set my maintenance reminders specifically the A/C filter and Air filter I have anissue. When I start my car and the reminders pop up to let me know what needs maintenance they switch. Like the A/C filter is supposed to show up the Air filter does instead and vica versa. But when you go into the maintenance section the correct one shows up???? Also now my radio presets specifically number 2 and 6 switch themselves every so often. PLEASE HELP ME! I have the car in the dealer right now and so far this is the third dealer. The screen and the ECU in the trunk have been changed. This has not helped.

 

Seems like a very strange issue... I'm not sure if they are related, as I have never heard of this technical problem before. So your saying 2 Radio presets switch, adn the same with the AC and air filter reminders?

Minor attempt you can try: If you can switch to a 3rd Gen ECU? you will get more features, and tis the same one as the 02-05GS. See if the dealer will agree, since they tried so many times.

 

Thanks. Anyone else have ideas? Gotta pick the car up tomorrow.

 

No one else?
