Reviewed a 2016 Buick Sedan FWD on Jun 06, 2024

This car ran like a dream for its first 100k or so miles, but once it hit that 100k, its been problem after problem. Ive had the entire transmission rebuilt, as it started slipping, and it has continued to throw up other issues with the engine since then. My first car was an old 05 Buick Lacrosse, and that thing was built like a tank; it was in multiple accidents and didnt give out until well over 250k miles with just basic maintenance. This one pales in comparison. Its a nice ride, for sure, with nice features, decent-ish gas mileage, and like I said, its great until you hit that 100k mark. Once you hit it, be prepared for many problems back to back.

My 2017 Buick Envision Essence was the best car I ever owned. No mechanical issues and Buick comfort. I drive it for 7 years one set of tires , oil changes and a battery 108,000 miles. So I bought a new 2023 Buick Envision Essence ; loving it too.
