While driving on the interstate at 75 mph, the top trim from my grill flew off unprovoked hitting my windshield and roof of the truck. Luckily there wasn’t anyone behind us but the noise definitely spooked myself and the passenger not knowing what just hit the windshield. I took it into the dealer from who I purchased the truck and told the entire grill must be replaced for a whopping $1571.26 not covered under warranty. The truck only has 24000 miles on it and cost near $80K. Thanks GMC!! Scorned customer.
