“Issue with the trailer brake system keeps coming up on my dash. I know a lot of other people have had the same issue keeps dinging will not stop causes me to get distracted while driving. Unable to use other features because of this distraction and safety issue. The safety issue needs to be fixed this is an effective product with so many people having an issue you need to do a recall. I did let Graff Chevrolet in Mount Pleasant Michigan no and I took a picture and showed them.”
