Buick
Envision

During multiple drives the vehicle completely shuts off when driving or at lower speeds. When this occurs (4 times over the last 3 months) the vehicle has no power or ability to restart creating a major safety issue. You cannot turn on the hazards or anything in the vehicle. The vehicle is still in drive (because you were driving when it occurred) and so you're unable to shift back into park to restart. After some time you are able to restart the vehicle and continue driving.

New tires placed. Oil change next day noted oil leak on differential due to gasket. Mechanic tried to obtain gasket but system told him because my VIN was below a certain number I would need a new differential. Additionally, gasket could not be obtained. Buick knew a problem existed and changed manufacturing, hence, VIN above that certain number has no problems. What all of us below that VIN number?

When traveling crossing over a bridge onto a highway, my tire started to shake uncontrollably. I went to a tire shop and they found nothing. Upon traveling recently it happened again while on the highway. This issues has affected my tire pressure sensors. I was informed that this is called shudder bucking and only happens when driving at a high speed. Upon research, I was able to find out that this is a known issue for my vehicle model made between the years of 2016 and 2020. This a complete safety hazard and concern and should not come at the expense of the vehicle owner.
