And then mine all of a sudden fixed itself…for now. For the heck of it, Even though the issue went away, i replaced the original battery with the top of the line one from autozone. Fingers crossed as otherwise we absolutely love the car!!

Update on our 2016 Honda Pilot. After the battery tested good, Honda replaced the start/stop on the extended warranty and the issue persisted. They kept the vehicle for a week, observed the issue but no error codes were triggered. The agreed the next step was to replace the keyless control unit for $750. We’ve had the vehicle back for 6 weeks with no issues. I’m keeping all records and hopefully they will realize a recall needs to be done.

There have been a few of these Keyless control units failing so there may be some sort of warranty extension or recall in the near future. Wise to keep all the documents just in case.

Looking to keep this thread active as i am AGAIN having this issue with the alarm randomly going off. I had about one month of normal activity and then all of a sudden out of the blue in the middle of the day the alarm started going off. Trying to determine if the best course of action is replacing the keyless control unit and if it’s anything that can be done DIY. If not what is the average cost of the unit and the dealer install?

I’m having the same issues with my 2016 Honda Pilot - random alarm going off (even when unlocked), lights turning on, flickering dash with clicking sounds. I’ve had it to the dealer 3x and they never found errors but they replaced the car battery & key fob batteries, and the start/stop button from the keyless remote issue.
still having issues…..
Is the keyless control unit the fix? Has anyone had issues since that was replaced?

We are having the same issue with our 2016 Pilot, starting yesterday morning. It's exactly like the pp's video. Removing all of that black plastic [email protected] that covers up access to the battery while I'm at work and re-attaching everything in the Texas summer heat is not an option. I am worried that it is going to run the battery down, so we are keeping it unlocked and have turned off the lights, radio, and AC when we're not in the vehicle. I can't get it in to the Honda Dealership until next week, as they are swamped with a recent unrelated fuel system recall. I did find that civic owners were having similar problems and had the BCM replaced. Is that the same thing as the keyless control unit in the Pilot?

I bought a 2016 Pilot EX-L in January 2020, and love it! However, in May 2020, I had the same problems as described above- clicking noises and flickering dashboard lights for no apparent reason. Took it to a dealer, and they found nothing. It happened again in Feb. 2021, and I was able to record what was going in. This past Monday I took it to another dealer, and they replaced the Start/Stop unit free of charge due to the warranty extension. They tested my battery and it’s fine as are both of my key fob batteries. Today, it starTed doing the same thing- clicking and flickering dashboard lights- HELP? Now what?

I would love to but was scared off in reading that after replacing the module, your keys have to be reprogrammed before you can operate your vehicle. I ordered the OEM part of the internet and am having my Honday dealership replace it in the next 2 weeks. I've got half a mind to have the dash already all disassembled so they can't charge me their ridiculous number of hours they claim it will take. I'll update all with the results and the cost when it is complete.

This issue with the dash panel flicker, relays clicking, and alarm going off unexpectedly started for me last fall. I already replaced the faulty start/stop switch last spring.
I replaced the battery, but the problem returned in February. It gradually got worse and the alarm was going off about every 5 days.
I found that the alarm could be disabled by disconnecting the sensor wires to the hood release, and turning off the auto headlight feature so the headlights wouldn't turn on intermittently. The problem still caused the interior lights to go on when the dash lights and relays went crazy.
I took it to my Honda dealer and told them to replace the keyless control module. This is the module part number for a 2016 EX-L (Control Unit, Smart Power - Honda 38320-TG7-A32).
It has been 3 weeks after replacing the module and no issues.

Selfishly I’m happy to hear that someone else had the same issues AND that the control unit resolved the issue. It stinks that Honda isn’t coming forward to say they obviously have a flawed part.
Can I ask how much you paid in labor at the dealer? I’m most interested in how many hours they charged you. Did they have to reprogram your key fobs and did they charge you for that as well?

thanks!

The control module was $427 and the labor including reprograming both key fobs was $225. I don't know the labor per hour charge. I watched from a distance the key fobs being reprogramed, and it took a few minutes per fob.
Good luck with your repair.

I just got my control unit replaced and fingers crossed that my beloved Pilot’s random car alarm issues are gone!!

For others, I bought the part myself online for $295 and the dealer only charged me for 1.5 hours of labor at $124 / hr which included the reprogramming of two keys. Still hated having to pay $500 for a faulty part that Honda should really have on a recall list!!!

Hello! Do you have an update on the issue? Was it ever fixed? My 2017 Honda pilot is doing the exact same thing. My kids left one of the lights on in my car, and I had my battery jumped what are you doing. Then my alarm started blaring randomly and my dash flickering just like yours.
We purchased our certified used 2016 Honda Pilot EXL AWD 1.5 years ago. I’m having an issue with the dash lights flickering and the anti-theft going off repeatedly the last two evenings. We had to unplug the battery last night for it to stop. Any suggestions on where to start?
