The August 2018 purchase of this SUV was record-breaking in that it was my first SUV and the newest vehicle I had ever owned. Within a year and a half, in January of 2020, I learned that GM believes that the engines in their vehicles can only be expected to last 5 years and that it is too bad, so sad that the engine in my vehicle stopped working. Anyone I spoke to found it inconceivable that a properly serviced vehicle would need to have the engine replaced at less than 100K miles. GM believes that since I did not have one of their dealers handle the repairs for my vehicles, there is nothing they can do as only their dealership can accurately diagnosis the cause of the engine failure and due to the age of the vehicle (barely 6 years old) it is solely my responsibility. The non-GM explanation as to the cause of the engine needing to be replaced was that the number one cylinder had grenaded damaging the electrode on spark plug.
