2023 GMC Canyon Lighting Problems

I use the right turn signal to make a right turn at an intersection. I proceed with the turn and begin to accelerate out of the turn, as the steering wheel unturns the right turn signal is supposed to cancel as the steering wheel straightens out. Instead of cancelling the signal, straightening the wheel when accelerating out of a right turn cause the left turn signal to be triggered and in gives three signal indications for a left turn. These left turn indications are uncommanded by the driver. The issue is repeatable. It presents a serious safety concern because other drivers are being told by the truck that you intend to do something which you are not at all intending to do. Another driver could rely on these uncommand left turn indications and pull in front of the truck and cause an accident. This issue has been raised with two dealerships, one dealership replaced the turn signal triggering and cancelling mechanism in the steering column. Both dealers ultimately told me that the issue was "software" relating and that it could not be fixed. One of the dealership claimed to have "corrected the issue with a software update." That assertion was a lie, the issue remained unchanged. This issue is a serious safety issue. The truck has a defect that puts me, my family, and other drivers on the road at risk. So far, GMC has failed to remedy the "software" issue and merely returns to me a defective vehicle.

While driving to work today in fog, the vehicle auto headlights sensed enough light and turned off. Because it was foggy outside I did not feel safe only driving with DRLs on so I attempted to turn on the headlights using the touchscreen controls. The headlights would not turn on. I have video evidence of the headlights not responding to the touch controls and remaining off despite trying to turn them on.
