The audio system on my Honda Pilot is failing with the error message "No audio connection". This problem appears usually after driving the car so it is warm to hot, it was 110+ in Phoenix on Saturday when it last failed. The problem seems to happen when the auto stop feature is enabled and the car restarts. The condition is not cleared by restarting the car. While in failure mode the system is very slow to boot, about 45 seconds.

After the car sits for a bit and cools off the condition clears, the system reboots quickly and audio is restored.

The car has both recall updates applied as well as the MOST connection service bulletin, 20-058.

It went about 400 miles between the service bulletin and the latest failure.

Has anyone else seen this failure message? I'm wondering if my problem is different than those that were supposed to be addressed by the recalls and the service bulletin.

I'm wondering if the battery may be marginal since the car was on the dealer lot for an extended period of time and they didn't replace it for me on delivery. It tests fine they say.

Also one of the recalls change the temperature threshold for the amplifier, but I'm wondering if the amp can actually operate at the new higher temperatures or perhaps my amp is marginal.

I've asked about both ideas from the dealership but I don't expect to hear back for a day or two. I'm grasping at straws. About 900 miles on the car. First failures at less than 500 miles, now recently less than 1000. I can't drive it this way forever.

From other posts that I have read, it sounds like an antenna problem. Most people seem to fix the issue with the installation of a new antenna. Since you report that it seems to be heat related, it may just be a loose connection at the antenna itself. Please keep us updated on what it takes to get this issue resolved.

I will certainly report back if they are able to sort out this issue.

Can you include a link to any thread here or elsewhere that describes the antenna solution? I'm looking but cannot find it.

Thank you so much!

Did they install TSB 20-047? Maybe the bulletin could be tied to the audio problem.

Spoke with the dealer service department today. He said without inspecting the vehicle in a failed state, they can't do anything. But, the tech said he'd seen it before and it was probably the amp overheating. Supposedly Honda says that they can repair it in firmware, but the tech's been waiting for 6 months. They won't replace the amp without Honda's permission, but Honda is not giving them permission.

It doesn't seem like all Honda's have this problem otherwise the Huns would be at the gates. So, some amps are more susceptible than others apparently. Swapping the amp would seem like a reasonable thing to do in the absence of a firmware repair.

I'm debating on trying to recreate the problem by driving around for several hours in the Phoenix heat and saving the diagnostics for them, or just swallowing my pride and trade the car for one I can depend on. Not sure what that would be though. I was pretty certain that the Pilot would be my ride for awhile after looking through the rest of them the first time.

I also don't want to be driving in the middle of New Mexico on the way to wherever and have the amp overheat and have no audio of any sort until the amp cools off. Then taking it to Honda and they say, "Sorry, we can't recreate the problem."

Very torn and discouraged.

For us, the progression of this problem was:
  1. Noticed occasional loss of BT phone connection
  2. Occasional crackling/popping with BT phone
  3. This weekend, we lost audio for the first time with "No Audio Connection" displayed at the top of the main touch screen during a 1-hour drive.
If you ask me, this has more of the earmarks of an electronic rather than a cable connection problem.

Related to this, family members with iPhones often lose their BT connection, resulting in call hang-up. This never happens with my Android phone. Is it possible that the Apple BT radio (in phone) has trouble maintaining a connection with the Pilot radio?

Thank you! My problem seems to be different. In my situation, I get no audio from any source, that includes FM, bluetooth, Car Play, everything. No matter what I select I get "No audio connection" on the head display.

It's very much like this thread here No Audio Connection available 2018 Elite but noone replied with a solution.
I’m having the same issue with my 2020 pilot EXL.” No audio connection “ with any source. Starts out with crackling like an intermittent audio connector sound. And then goes completely out. Initially thought it was related to the steering wheel controls but that was not the case and then I thought it was related to hitting bumps but it seems that had no bearing either. I really hope there is a solution to this issue seeing how I just bought this vehicle 2 weeks ago.

So, you haven't had that done yet?

We have not had a recurrence of the problem since the Fakra service a month or so ago.

The problem you are describing is an overheated amplifier (see the diagnostic screen). This will be be my 3rd summer of dealing with this and nothing being resolved. My understanding is the amplifier is located near the rear passenger tire. It's not an antenna is, harness issue, connector issue, or anything else. Honda America has done nothing to help either. It's extremely frustrating not to have any sound, Bluetooth phone, or Google maps working on a trip. This will be my last Honda!

How do you pull up that screen?

Hopefully, sometime in the distant future, Honda will finally come to their senses, remember how they originally built their reputation and refocus their energy on quality, reliability and service, not just shareholder value. Unfortunately, they lost their way.
