What customers are saying
The Mercedes-Benz GLS450 provides a spacious, quiet interior and solid fuel efficiency, complemented by a comfortable ride that appeals to luxury buyers. Concerns like inconsistent reliability, limited dashboard usability, and older technology compared to competitors may impact buyer satisfaction. Maintenance costs are high but expected for a luxury SUV.
2021 Mercedes-Benz GLS450
faulty engine
My Mercedes I bought in 2021 had many issues right from the start. I think it had a faulty engine and I didn’t realize it until it stopped suddenly as I’m driving it on the road. I could’ve been killed if there was moving traffic behind me. So many other issues such as AC/heat does work consistently. Automatic Seats don’t move sometimes, phone charger dock doesn’t work, park gear didn’t work sometimes and many other issues. Mercedes refused to take this car back under the lemon law as it clearly is a lemon! My car was in the shop for months and I lost value on it as they had to replace the engine. No compensation was offered except one month payment which I refused. The car still doesn’t drive well and AC/heat still doesn’t work along with other issues. I feel very wronged by Mercedes.

A great car with power and features
PROS
Technology and Entertainment
Tech in this car is great! It does what one would expect of a luxury vehicle. However, vehicle customization abilities lag its competitors
Ride and Handling
comfortable seating with an ability to customize the fit. the finish feels like it should with luxurious materials.
Cabin Noise
very quiet ride with very minimal noise for the size and design even at high speeds.
CONS
Dashboard
sometimes the driver’s console takes a bit of time to start. The ability to customize the ride is less than its competitors.
