When driving vehicle, alert sounded lowered speed detection and my engine light came on. My vehicle then lagged power and it smelled like something was burning. Called dealer i bought vehicle from and i drove it in to them. I just bought the vehicle 8 months ago. I was just in to same dealer for a GPS tracker that was in my vehicle unknown to me that the Onstar stopped working and the dealer had stating they missed it in the pre certified inspection and they had to replace the telemax module do to the unknown GPS Tracker. My vehicle is now in for the lowered speed detection problem which my GM app stated it was an air induction system problem. I do not have paper work for the air induction system yet but i have sent photo of what my GM app produced.
Screen went black on 3 different occasions, since purchasing vehicle

The contact stated that while operating the vehicle, the service message was displayed, and the audible turn signal became inoperable, along with the collision warning and the On-Star feature. The cause of the failure was not yet determined. The dealer was notified of the failure, but no assistance was offered. The manufacturer was not yet contacted. The failure mileage was 22,000. The VIN was not available.
OnStar module failure Its backordered across the entire country, its only reasonable to assume it's a problem. Online information I've seen is it's an issue with a lot of vehicles
The vehicle has been having misfires and power liftgate since owning the vehicle. The vehicle has been to multiple dealerships and I have to this very day put 15k miles on the vehicle. Needless to say GM has not been any help in getting the problem taken care of. I have sent GM video of the vehicle misfire. I finally have conformation that the vehicle has had 53 misfires.
The infotainment center has a tendency to freeze upon starting the car. Subsequently, when the car is put in reverse the back up camera will remain on for several minutes after putting the car back into drive causing a distraction to the driver. The freezing of the infotainment screen will often stay frozen even after turning the car off. When the car is off and the door is closed and locked, the screen stays on and music stays blasting, unable to turn the music down or off even though the car is off and locked with no one inside. The screen has stayed on for over an hour and upon returning to the vehicle, the car took several tries to start. I can only assume that the freezing is beginning to cause the battery to drain. This is causing a safety concern as loud blaring music is distracting and the possibility of being stranded without being able to start my car is a scary thought. This problem has been occurring since I purchased the car and has not been able to be reproduced by the dealer as it only happens randomly a few times a month.
Mientras conducía el panel de instrumento digital donde están los relojes se apagó en su totalidad. El auto siguió funcionando pero no podía ver nada en el panel porque estaba literalmente muerto. Me moví hacia un costado de la carretera y apagué el carro. Lo volví a prender pero el panel siguió muerto. El carro si trabajaba. Llegue con mucho temor a casa y lo envié al concesionario donde lo compré. Me dijeron que era el panel de instrumentos y que lo tenían que cambiar.
