Lie!!! That is a lie. Go to the dealer and tell them to contact GM. It only melts w chrome bumper. The curve on the bumper creates a heat focal point that melts that point on Botha sides. I’m actually the first person to have noticed and now my dealer went out and checked their trucks. And found three trucks where they also melted. The dealer I contacted is martine Chevrolet in Torrance California. They are great. This is an issue that GM I now aware of and is starting to figure out the best solution. Mine was replaced and started melting a week later lol.
