The horn appears extremely stiff. Large amount of pressure needed to honk horn – especially the lower half.
Bit of a safety issue. Tried most other models in showroom and they all were much softer and could be done with your pinky.
Is this a known issue?

Yes I agree, could not get it to work until I figured it out. Not happy with the new Acadia will look at a Cadillac XT5

A pal of mine had the same issue, but still works and sounds well. He had it for almost 2 months now.

Are you folks referring to the all-new model, or the first-generation Acadia limited?

The all new 2017 Acadia Denali is what I have. The horn is incredibly stiff and on some points of pressure almost non functioning.
Have had a terrible time with GM on this. The dealership called it “normal” for a new car. I submitted a video doing a “pinky” test on every model in the showroom – plus ford, Nissan and Chrysler show rooms. Every horn could be easily sounded using the only the pinky finger – except the Acadia. The 2017 Acadia needs heel of the hand whacking at the horn to make it work. Even then it misfires if you don’t get it right. My wife is petite and cannot use it with certainty that it will work when needed.
I am in a holding pattern for 30 days until GM responds with a possible remedy.
For us it is a safety issue.
Don’t get me wrong, the 2017 Acadia is a sweet driving vehicle. But he QC at GMC appears to be in need of life support. I had muffler stuffing trail out of the tail pipe on day 1. Day 4, the fuel pump and sensor needed replacing. Now there is a recall on negative ground or something – the dealership just mentioned it last week, but gave no details.
The strange thing is, there does not seem to be any standards for horn pressure/resistance? Seems odd for a safety mechanism.

Hmm OK my pal owns the first gen

My Acadia Denali delivered February ’17. The horn is nigh inoperable. Occasionally with a strong fist to the top half it will beep like a ’64 Volkswagen. To say it’s a safety issue is an understatement, even more than the ear splitting buffeting if a rear window is opened. I WANT MY MONEY BACK!!! Most disappointing $50k I’ve ever spent, and far from GMC quality, and literally painful to drive!!!

Same problem with my 2017 denali…horn takes more pressure to operate than physically possible while driving. GM is ignoring the problem. Took it back to the dealer and EVERY one like it had the same
Problem. NO FIX. GM has ignored this way too long. They don’t seem to care about customer satisfaction..or safety. See ya in court.

GM notified me, last week, that a service bulletin is out for a horn “enhancement” on the 2017 Acadia horn issue. One could chuckle at the “enhancement” label they used, but at least they are dealing with it. Does not explain how such an obvious flaw passed their engineers and QA and made it to the streets. Believe the enhancement is under warranty.

…brouhaha, can you be more specific? How did you obtain the notification and are you able to copy and paste it into this site? Did you get any indication when the service bulletin would be available to the dealerships? Thanks for any insight. There are a lot of 2017 GMC Acadia owners hoping this gets fixed before something bad happens. Good luck with your horn!

…does anybody pay attention to this website, or even the NHTSA website? This wide-spread HORN PROBLEM is potentially lethal. C’mon GM, fix it. C’mon NHTSA, do something about it. There is no proof of any “horn enhancement” service bulletin.

Hi.. hard time accessing this site. Had to create new user and use smartphone browser. Weird.
Anyway…. I was told today by gm canada that dealer has parts. If the case, they are long overdue, but did resolve. That is nice.
One does worry about their understanging of issue. Was not till I had lawyer write them a nice letter did they start to take it more serious.
Where was their QA during development of the car – or production.
They are calling the fix an enhancement! Grown up adults sat in a room and thought that sounded better than “sorry, our bad, we will look after you better in future”

gmbruhaha, that is good news, I think. Did they actually install the new parts in your Acadia and now everything works ok? Thanks for keeping us informed. At least GM Canada is doing something. Still no help from GM USA. I have written to the CEO of GM USA (Mary Barra) but no response from her. No word about any TSB down here either.
Please let us know what the final resolution is, and I will do the same.
There was something fluky about this website for a couple of days last week.

###HORN FIXED####HORN FIXED####HORN FIXED###
GM has come up with a fix for the horn problem on the 2017 GMC Acadia. Service bulletin 17-na-367 was released 11/20/17 that detailed replacing the steering wheel harness with a new one, possibly a new design. The repair takes about one hour and should be available at all GM dealerships. So there is no reason to continue driving an unsafe vehicle because the horn does not work. The fix was done on my 2017 GMC Acadia Denali and all is well. Good luck to those that have the same problem with their Acadia.
