GMC Sierra 1500 Limited

The front grill deflector sheared off of the truck when driving in the highway. The highway speed was 65 mph and the deflector flew out in to traffic. There was no warning or symptom prior to the problem or failure. This is a common ongoing issue with the same make/model of the previous year 2022 with an actual open recall unfortunately.

The attachment points for the upper chrome grille deflector have fractured, causing the trim piece to detach completely while driving and fly over my windshield which startled me and made me swerve dangerously. This is a known recall for the truck year before me and should clearly affect my truck too since the same description happens here

The problem is in the power-locking manual tailgate’s exterior release switch assembly. Water intrusion into the switch can cause a short circuit, leading the tailgate to unlatch while the truck is in Park. Once moving, momentum and air pressure can cause the tailgate to open further, potentially dumping cargo onto the road and creating a hazard.

I was able to savely move forward in limp mode, but the shifting was harsh. I was able to find an empty parking lot to safely park. The…
