Speaker wires and connectors corroded

this is currently happening to my 2015 corolla S. take the door panel off and check that the plastic covering that goes overtop of the electrical components is sealed (the black goop) all the way around. Thats what was letting water inside the door. If you need to reseal it use goop automotive adhesive, it works great. Goodluck

I found the same thing on my 2015 Corolla S today. Wires and speaker plugs coroded took the opportunity to replace the speakers as I was already taking the door panels off to repair the connections. Pretty easy job to do yourself if your handy. The connections on the factory speakers can be run straight with speaker wire if you have a soldering iron.

Please call Toyota to get a recall started for this. Funny they haven't had any other complaints except mine :/

My 2014 has the problem.

Me too.

me too.

2014 Corolla. I called the 1800 number and left a complaint

It happened to me. Mine is covered under warranty but,,,,,,,,they have to investigate it and charge me for the investigation. 65 bucks easy. I can get speakers from the wrecker and put them in for less. I'm going to send them a bill and do the Trump thing. I will say you owe me, they will say they don't. I will propose third party mediation. If they refuse I will win in court because the first thing the judge asks is, did you try to settle. They won't accept 3rd party mediation because it costs them more to attend than to pay my claim.

So, after attempting to negotiate with head office and the local Toyota dealership, I came to the conclusion that I wasn't going to win against them. I made an appointment to have the issue dealt with. I spoke with the son of the owner and expressed my upset, only to have him approach me (after I had waited for the repair to be done for over an hour) and inform me that they didn't have the "right parts ordered". How this is possible considering they sold me the car, had all the pertinent info and should have been able to do their job properly. I left with them promising they would call as soon as the right parts were in. I was extremely angry, to say the least! I drove to a local audio install shop, explained the issue and bing, bang, boom, the local guy fixed the wires problem and charged me, drumroll please... $10!!! I went back to Toyota and told them to take their parts and never contact me again! I don't trust them, they blatantly lied in order to just get me to pay for something I didn't need and didn't have the decency to apologize for their screw up! Never again will I deal with Toyota...when this one bites the dust, I'll choose a Honda, Nissan, Kia...hell, anything but Toyota!

On My Corolla S 2014 too !

So I fixed my speaker. The speaker connector was the problem inside the door panel. I opened it up, cut out the connectors, and spliced the wires directly. They are back to normal. Very simple fix... those connectors corroded or something. There was a lot of white residue materials that made the connection bad. I could not clean it since the connectors are very small. I suggest just bypassing the wires. In retrospect, I would not cut out the connector in case Toyota later changes their mind and do something about it. One can easily bypass the connectors with minimal electrical wiring experience. I used 14 AWG wires (american wire gauge). If you can find a thin 16 AWG, go ahead.

Same white corrosion powder on my 2014 Corolla LE+ also---both doors! Cheap wiring---not copper.

Not happy withToyota my 2016 have the same cheep wirers Toyota no more 4 me

I complained to the dealership, they initially said it wasn't covered by warranty, then the next visit, said my upgraded warranty does indeed cover it, provided I pay $115 for an inspection to confirm corrosion. I didn't feel that was fair, as a warranty should cover defects without an additional fee. I griped to head office to no avail. They used aluminum wires. That's all fine and dandy if they have something to prevent oxidation. Aluminum oxide doesn't conduct well, so the speakers crackle and cut out until the resistance-generated heat accelerates the corrosion until it turns to white powder.... it could also be a reaction to whatever the connector's made of. Aluminum is very difficult to solder without the proper prep chemicals. I may yet try getting a tube of conductive antioxidant paste for aluminum house wiring to see if that prolongs the in-service life of the wires, before I engage in a more involved process of rewiring the darn things.

Same thing happened to my 2015 Toyota Corolla S where the wire got stripped from the driver side speaker. Easy $10 fix, just solder it back on. https://www.amazon.com/dp/B087Q9NB8X/ref=cm_s w_r_cp_apa_fabc_4T59FbBYMTEJR

I'm currently having the same problem. I noticed it when I was on the phone and call sound went. Music works fine, I just can't hear phone calls. Is it a simple fix?

Keep complaining to head office. This cannot backfire. 2 hour job, max, that's under 200 total. I fixed it myself. Tell them you've teamed up with my friend nobodyimportant74@outlook.com. If enough people do we may get enough clout to win. Shame on Toyota to not cover an obvious design flaw. The internal cost for Toyota to repair this on warranty is peanuts.

It is aluminum wire and it is oxidizing because copper and aluminum don't mix creates a chemical reaction, so these people think they fixed the problem but by joining copper connecters to any part of the wire, will be a short term fix ,as mine was , and it will oxidize again until you use copper wire all the way thru back to the stereo system. That's why houses aren't wired with aluminum any more because of oxidizing and if you do join aluminum wire with copper you must use antioxiding paste on the connections
