Hello
 

I have a 14 and my trunk has had at least 50 gallons of water taken out of it. SMH

In response to water in the trunk were their any findings ?
 

My wifes 2015 impala i have found water in trunk , and ideas of the problem that was found , also in this 2015 that radio has taken a crap no screen and no sound spoke to Chevrolet rep- and tells me radio onl6 has a 1 year warranty that i think is bull i am a lifetime customer and enjoy Chevrolet and Gm products be for this 15 we bought a 14 and had no issue so now i am faced with this situation.

I thought I read somewhere, possibly in a service bulletin, that if there is water intrusion into the trunk, then the amplifier should be checked for damage from the having water in/on it. I've been looking where I saw this, but no luck yet.

I have been having the same problem and it got worse. I originally thought it was the HMI module or even the radio module, and changed both with new ones on my 2014 LTZ and sound would still go in and out. Not sure what to do now. I don't know where the factory amp is located to take a look at it. I changed the fuses of both the radio and amp with new ones (even though I tested them and they worked) and still nothing. I called the dealer and they mentioned that it would cost over 500 for the part and about 250 for labor. I shouldn't have to pay that much for just the stock stereo when I paid over that much for a new HMI and radio modules that are doing the same thing as the original. Just now I have android auto/carplay, but can't use it because of no sound, even blinkers have no sound. Please help, has anyone able to fix or know what the problem is with out just taking out the fuse which seems to do nothing. All I know is that everyone, if you turn off the car for about 2 mins or more, it will temporally reset the system, but after a short time the sound will go in and out again.

Please help.

Paul have you had the car scanned to see if there were any error codes?

Dont go to dealer
 

I had the EXACT same thing happen to me. Trunk somehow gets water in there. Radio began coming and going. Dealership wanted 800 to replace amplifier but they are not sure that it qould fix the problem. I spent 100 to replace amp. Door, turn signal, and oyher chimes now work but still no radio. I am stumped. I would like to fix problem, but no one knows how.

Reception on 2014 impala ltz
 

does anyone know how to fix the audio off problem of an impala 2014, I’ve tried everything the satellite radio receiver module and the radio are new, but I still having the same problem, and I don’t really know what to do next.
I already tried the hard reset with the door and remove the negative from the battery but nothing changed.

Same here on my 2015 1LT
 

Did you ever get a fix? Your issues is exactly what I'm experiencing and can't find an answer anywhere.
