2014 GMC Yukon Denali
A couple of month ago, the horn started honking randomly every once in a while when shifting into reverse as well as shifting from reverse into drive. Pretty sporadic at first but happened more and more as the weeks went on. Does not happen every time however. When it does happen, it is always within a minute or two of starting the car. Once operational for longer than that there never appears to be an issue.
Three times now in the past couple of weeks, the car has just started horn blowing when locked with nobody inside. The first time it started about 3-5 minutes after we got out and locked it and were already in the restaurant. Happened twice last night. Once right after getting out and once at 3am in the garage after sitting in there since 8pm. When this happens it is a constant honk like someone is in there just holding down the horn. The only way I can stop it is by opening the car and hitting the horn.
Any thoughts on what the hell is going on?
