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. I have taken the vehicle to authorized dealerships for multiple service visits and repair attempts. Despite these efforts, the same backup camera failure continues to occur. Although different components may have been inspected, repaired, or replaced during these visits, the recurring problem remains the same: the backup camera display goes black when the vehicle is in reverse. The underlying cause has not been adequately resolved. The vehicle has been presented to authorized GM dealerships for diagnosis and repair, and the relevant service records should document the repair attempts and the recurring complaint. I have also submitted a repurchase request to GM because of the ongoing issue, but my request was declined. I am requesting that NHTSA document and review this recurring malfunction because of the potential safety risk associated with losing the rearview camera image while reversing. I am concerned that this issue could result in a collision or injury if the driver is unable to see a person or obstacle behind the vehicle. I can provide available service records and make the vehicle available for inspection upon request.

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. It will learn to lock out 9th gear and it will max out with 8th gear at freeway speeds reducing MPG. And it will fail to downshift appropriately while driving leading to the operator wondering why the vehicle will not accelerate when needed; this casual downshift delay then results in excessive downshifting to the lowest possible gear where the vehicle will then lurch forwards; and then it will pause and maintain said lower gear and continue accelerating for 1-2 seconds while the operator presses the brake pedal in response of the vehicle jumping forwards. Individual situations: 1) Lack of 9th gear use at freeway speeds. This is reducing the advertised emissions based on EPA testing. This behavior skews official EPA test results because vehicle operation is not as advertised. 2) Shift flair and unsafe shift delays. This is the most serious behavior. It leads to pauses and delays in acceleration of up to 5 seconds, and it leads to pauses and delays where the vehicle continues to accelerate up to 3 seconds after letting off the accelerator and pressing the brake. 3) Excessive wear. The badly learned behavior is causing issues with shift control pressure and logic, excessive clutch wear leading to damage and worn clutch packs. Analysis: - Resetting the GM Transmission adaptive learning to factory removes these problems, the trans will relearn bad behavior within 2-3 weeks of daily driving. Reset was performed using an Autel Hot function “Quick Learn” procedure for the transmission.

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 quoted $3,500 to replace the failed assembly. The vehicle displayed a "service power steering" warning message on the dashboard alongside an immediate loss of steering power assist. The failure happened suddenly while driving with no prior mechanical warning signs, symptoms, or gradual degradation.
