The wiper blade motor is defective. While driving during a storm the wiper blade motor stopped working on the delayed and low settings. This was a safety issue while driving. I took my vehicle to get looked at a GM Dealer to look at the vehicle. My vehicle is only 3 years old and should not have issues with the wiper blade motor.

The driver-side mirror on my 2021 GMC sierra is unusable at freeway speed. When traveling at freeway speed the glass moves due to wind and causes the reflection in the mirror to be blurry. The reflection from the mirror is blurry to the point that I'm unable to identify objects in the mirror and it is difficult to gauge size and closing speed of any objects in the mirror. The issue has been with the vehicle since I purchased it new in June of 2021. The issue has been reproduced by two different dealership service centers and the entire driver-side mirror assembly has be replaced twice with the issue persisting. I have videos showing the issue but they are too large of files to upload on this form.
