1 Transmission Failure problem

Failure Date: 08/16/2017

The transmission causes dangerous driving conditions. I have the same complaint as several others have reported. The transmission fails to downshift at lower speeds causing the hesitation when acceleration is needed. Pressing down further on the accelerator will lunge forward possible into crowed road way.

2 Transmission Failure problem

Failure Date: 01/01/2016

Truck transmission causes dangerous driving conditions I have same complaint as several others in the NHTSA customer complaint section. Basically the transmission fails to downshift at lower speeds causing the vehicle to hesitate when acceleration is needed until it downshifts appropriately. Pressing down hard on the accelerator will result in a downshift, but this is a potentially dangerous maneuver in crowed road conditions.

3 Transmission Failure problem

Failure Date: 06/01/2015

I have same complaint as several others in the NHTSA customer complaint section. Basically the transmission fails to downshift at lower speeds causing the vehicle to hesitate when acceleration is needed until it downshifts appropriately. Pressing down hard on the accelerator will result in a downshift, but this is a potentially dangerous maneuver in crowed road conditions. I have also gone to manual transmission mode but this is also potentially dangerous in crowded conditions and certainly inconvenient. Seems the volume of this complaint warrants a GMC response.
