Consumer Reviews for the Mercedes-Benz GLS-Class

Do NOT buy a GLS450 - The Worst!!!
No More GLS , 06/02/2023
2023 Mercedes-Benz GLS-Class GLS 450 4MATIC 4dr SUV AWD (3.0L 6cyl Turbo gas/electric mild hybrid 9A)
The GLS450 2023 just suddenly stalls while driving - loses all power - they don't know how to fix. It stalled out twice on consecutive days in first week of ownership! Nearly killed us - going to try BMW X7. We had a previous 2020 GLS450 that did the same thing 10-12 times a year and they never were able to fix it.
