Hey guys,

I just wanted to give everyone the opportunity to ask questions about their audio system and let you all know that I repair every Lexus amplifier from the original Nakamichi units all the way up to MY2021. There seems to be a lack of factual information available about the modern Pioneer and Mark Levinson audio systems and I'm here to provide guidance, assistance, and possibly do a little business. I hope that this isn't breaking any rules of the forum and if it is, I certainly apologize. I won't link my website at the time, as I assume that's discouraged. I certainly would like to be part of the community and be a resource, rather than pushing my services.

FYI - this particular vehicle has constant amp failure due to leaking floor vents. The base audio Pioneer amplifier is actually a reliable unit outside of getting wet.

Have you seen non-ML subwoofers go out?

OEMAUTOAUD

Yes, typically the voice-coils go electrically open. You can use a very cheap DMM to measure the resistance of the subwoofer.

any pics on this so we can be pro-active in preventing this? "this particular vehicle has constant amp failure due to leaking floor vents. The base audio Pioneer amplifier is actually a reliable unit outside of getting wet."

OEMAUTOAUD

No pictures of the vent currently, but it's mounted on the floor section and pretty easy to locate.

Hi, just got my son a 2014 IS250 F AWD. After a week with the car my son installed the Enform app on his phone and when he got to the car the radio asked for an upgrade. Now the radio plays for a few minutes and then reboots, another minute and reboots again, keeps doing it.
Any suggestion on how to fix it???
Thanks!!!

Sounds like the head-unit firmware is now corrupted or something along those lines. I don't currently offer repair services for the head-units. There's always a potential that a Lexus dealer can try a firmware update to recover the unit. If not, you'll likely need to replace the head-unit.

Within those few minutes it's working, try going into the navi menu and do a Factory Reset on the unit...likely if you were selling the car and doing a factory reset to clear out all your personal info.
For some that experience the boot loop after a software update, this fixed it.

@OEMAUTOAUD Welcome to the forum...have a look at this thread and see if there is anything you can suggest adding to the original post: https://www.clublexus.com/forums/is-...r-failure.html

I think the biggest question that some, or at least me, have...is this just a small part in the amp that goes that needs replacing, or is it a large pricey item? Is it typically the same thing wrong with each 3IS amp that fails? (speaking to mainly the non-Mark Levinson ones which I believe are Pioneers units).
I realize that expertise and equipment factor into the repair, so I'm assuming that this is not something the average person can tackle even with a soldering iron.

Yes, it did fix it (a least for now)and saved some $$.
Should we forget about trying the update again?? We don't care for the Alexa feature.

Thanks again!!!!!

Sasnuke

Check and confirm if the update actually took...it may have.
The factory reset i don't believe override software updates...of course we don't OTA updates in Canada (or at all), so I could be wrong.

When the radio was rebooting it had a button in the radio menu for “alexa” , after the navigation restore it is no longer there. Also the radio info on the instrument cluster was not working, now it is. I think the upgrade was somehow corrupted and never completed.

Sasnuke

You are probably correct that the update was corrupted.

You may want to contact the dealer, they may have the download available on a USB and can manually update the unit.
