In owners’ own words
Source: NHTSA complaint databaseFiled with NHTSA by the people who own these cars, about the electrical system. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.
The horn is very hard to honk. It takes my wife both hands to activate the horn. I have seen similar complaints on the computer. I have been back and forth with a GM representative for about 5 moths and have gotten nowhere. They apparently do not see this as a safety concern. I do.
Horn will not honk unless excessive pressure is applied. It takes 2 hands to honk the horn. I have never seen a horn that required more than 1 finger to honk
The contact owns a 2017 Gmc Acadia denali. While driving at an unknown speed, the horn failed to sound. The vehicle was taken to a dealer where it was diagnosed that the horn was poorly designed. The vehicle was not repaired. The manufacturer stated that the vehicle was functioning as designed. The approximate failure mileage was 400
I bought a new 2017 Gmc Acadia denali the end of february and the next day found out that the horn does not work. The horn is extremely hard to push and requires extra pressure with both hands and arching my back against the seat to try and make the horn to work. I have been back to the dealers 3 times in 2 weeks and it is not fixed.
Horn has not worked from day one. Dealer says can't fix until GM redesigns a solution. Sad
