GMC SIERRA 1500 2024 UNKNOWN OR OTHER
lowThe screen shakes. Goes black. Zooms in randomly without prompting. Started dialing up people from recent calls. While trying to get the navigation working. I started drifting into oncoming traffic. Fortunately was able to course correct and avoid collision. Buttons are most time not responsive to touch. It is distracting. The system has never fully worked as promised and is a distraction. And as a result a serious safety hazard.

GMC SIERRA 1500 2024 STRUCTURE:BODY
mediumThe front upper grille deflector detached and hit my windshield and bounced off behind me during a drive at normal highway speeds. This created a random flying debris object that appears to have been a problem with the 2022 and later Sierra 1500 models; however, the recall only appears to address the 2022 model. It also appears quite common for the 2024 year model as well. Vehicle has never been in an accident so nothing beyond typical use would have caused damaged to the connections. The plastic connectors appeared to have failed.
