This is a problem GMC knows about and laughs any time you call about it. When this flies off the next time and kills someone on a motorcycle, hope they have the same attitude. Remember, I've brought this up to my insurance and your reps., so have fun when the lawsuits start. You've known about this problem from the time you introduced this model. There is no excuse. This shows what you think about your customers. Kill a few more people and hopefully you will be out of business.
