Brakes- when reversing the brakes make loud grinding / squealing noise. I'm worried at times it will give out by not braking. Electrical- my display panel with the reverse camera turns off which at times can cause an accident.
Intermittently, the center console (navigation) screen and system crash at random. All audio stop and the screen turns black for a few seconds, before resetting to the default view and disconnecting all previously connected devices. This has happened at least 10-20 times while driving during my ownership of the vehicle. I can confirm that it happens when my iPhone is connected to the vehicle via wireless Apple CarPlay, but I am unsure about other circumstances where this may happen. It had happened regardless of which phone is connected or what operating system version is in use - that is, this issue has persisted across several different iPhones and versions of iOS, so it does not appear to be related to the mobile device. When this issue occurs while driving it is very jarring and can be disorienting, as any navigation or other audio ceases. The issue has not been reproduced by a dealer, and the components have not yet been inspected. There were no warnings or other symptoms of this problem. The problem first appeared within 1-2 months of purchasing the vehicle.
