Consumer Reviews for the Mercedes-Benz GLS-Class
Read recent reviews for the Mercedes-Benz GLS-Class
Beautiful combined with no QC
John Gamble, 12/22/2020
2020 Mercedes-Benz GLS-Class GLS 450 4MATIC 4dr SUV AWD (3.0L 6cyl Turbo gas/electric mild hybrid 9A)
The ride is absolutely stunning and the interior is downright beautiful. We love the tech and features... kids can’t get enough of the ambient lighting options. But there’s a catch. The build quality just plain sucks. We’re had the car for 2ish months, and it’s already spent 9 days in the shop. First, the high fan made a crazy loud noise. Then the rain sensing wipers didn’t sense rain. … Now we have a window that sounds like it is going to fail when we roll it down. Also there appears to be a subtle fit issue on the rear bumper. These cars are built in the US, and I get the sense that they have no idea how to put them together. There is so much tech, and so many points of failure. I feel like we are going to have a very close relationship with the dealer over the life of this car.
At least it’s pretty and drives well.
Update on 1/4/2020 - Two more issues after getting the car back last week... a check engine light and a warning that the collision avoidance system is disabled because the sensor is dirty (the sensor does not appear to be dirty). A word to the wise... think long and hard before buying this car.
