2024 GMC Terrain recalls

Infotainment System Crashed

The contact owned 2024 GMC Terrain. The contact stated that while stopped, the gear shifter independently shifted from drive(D) to park(P). The contact turned off and restarted the vehicle several times and the vehicle operated normally. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed, and it was determined that the transmission needed to be flushed because debris were found inside the transmission. The transmission was flushed and the vehicle was repaired. The manufacturer was notified of the failure and opened a case. The approximate failure mileage was 11,050.

I am reporting a recurring backup camera malfunction in my 2024 GMC Terrain AT4. Since purchasing the vehicle, I have experienced repeated instances in which the rearview camera display goes completely black when the vehicle is shifted into reverse. This prevents me from seeing the camera image while backing up. The malfunction presents a safety concern because the rearview camera is an important aid in identifying pedestrians, children, objects, and other vehicles behind the vehicle. When the display goes black, I lose that visual assistance, increasing the risk of backing into a person or object, particularly in parking lots, driveways, and other areas where pedestrians may be present.

GMC Adaptive learning transmission problems that lead to safety concerns, emissions reduction in MPG, and increased wear of the transmission. Regarding GM’s 9T45 automatic 9 speed transmission. Problem: - The GM Adaptive learning of the transmission does not have safe guards in place to prevent unsafe sift patterns and behavior. This results in shift flair behavior where the transmission will drop out of 3rd gear and pause before shifting to 4th gear.

And it will fail to downshift appropriately while driving leading to the operator wondering why the vehicle will not accelerate when needed; th

The Electric Power Steering (EPS) gear assembly / rack and pinion failed completely. Yes, the component is available for inspection upon request; it is currently located at the servicing dealership. A total failure of the steering gear assembly caused immediate loss of power steering assist, making the vehicle extremely heavy, rigid, and difficult to steer or control. This sudden mechanical/electronic failure puts the driver, passengers, and other motorists at extreme risk of a collision, especially if it occurs at highway speeds or while negotiating a turn. This did fail on me driving down the Highway! Yes. The problem was officially diagnosed and confirmed by the franchise dealership. They
