I too am the victim of this ridiculous GPS antenna problem. I purchased a 2015 Suburban LTZ with all the options in Nov. It was in the shop twice with intermittent GPS problems before it finally failed all together. They said it was a bad GPS antenna. (Incidentally it first failed after sitting in airport parking lot after a heavy rain) Well they had to order the antenna that was back ordered for almost 3 weeks. Back in to service to have it painted and installed. Great finally fixed, all is good! Not so fast...

Was at a golf outing this week where we had a 15-minute downpour. Got in the car and have the dreaded red "X'" over the GPS symbol at top of nav screen...its has freaking failed again. This should not happen with a $70,000 vehicle. Chevrolet customer service/support please speak up and help!! as I think my dealership is clueless about what to do next and in the meantime I do have GPS, OnStar, etc. This is exceedingly frustrating...

Any members who have had the problem resolved...I'd love to hear from you as well.
