2021 Mercedes-benz Gls580 problems
The Mercedes-Benz GLS, formerly Mercedes-Benz GL-Class, is a full-size luxury crossover SUV produced by Mercedes-Benz since 2006. In each of its generations it is a three-row, seven-passenger vehicle positioned above the GLE (formerly Mercedes-Benz M-Class before 2016). The GLS is considered the flagship of the marque's SUV lineup, although the body-on-frame G-Class (originally intended for military off-roading but also offered in luxurious trims) is more expensive and has been in production longer.
The GLS shares the same unibody architecture with the GLE. Most GLS vehicles are assembled at the Mercedes plant in Alabama, except for a small number of early 2007 production vehicles which were manufactured in Germany. The first generation model (X164) was manufactured between 2006 and 2012 and was replaced in 2013 by the new generation GL-Class (X166).
From 2016 with the release of the facelifted second generation model, the GL-Class was renamed to GLS as per the revised nomenclature adopted by Mercedes. Under this scheme, SUVs use the base name "GL", followed by the model's placement in Mercedes-Benz hierarchy. The "G" is for geländewagen (German for off-road vehicle) and alludes the long-running G-Class. This is followed by the letter "L" that acts as a linkage with the letter "S", the SUV equivalent to the S-Class, marketing the GLS as the corresponding SUV to the S-Class full-size sedan.

Common 2021 Mercedes-benz Gls580 problems
The 2021 Mercedes-Benz GLS580 has been reported to have several common problems based on complaints from owners. One of the main issues is related to the 48-volt system. There have been multiple threads on forums discussing problems with this system, with some owners experiencing issues. However, it seems that Mercedes-Benz has addressed these problems with updated parts and software updates, as there have been fewer recent reports of problems. Despite this, it is essential to note that the GLE/GLS generation is below average in reliability, and some owners have had lemons. However, many owners have also had trouble-free experiences.
Another issue reported is related to the seats. Mercedes-Benz USA, LLC (MBUSA) issued a recall for certain 2020 GLS450, GLS580, GLE350, GLE450, AMG C63, and 2021 AMG GLE53 vehicles due to incorrectly assembled seats. Dealers will inspect and repair the seats, as necessary, free of charge.
Additionally, there has been a recall for certain 2019 AMG G63, C300, E300, G550, AMG GT63, AMG GT53, 2019-2020 A220, GLA250, GLC300, 2016 C300, 2020 AMG A35, AMG C43, AMG C63, CLA250, E350, E450, GLB250, GLE450, GLS450, GLS580, S560, and SL550 vehicles equipped with a gasoline engine. During the manufacturing process, particles may have been trapped between the fuel rail and injectors, which can cause a fuel leak. Dealers will replace the fuel rail and fuel injectors, free of charge.
Furthermore, there has been a recall for certain 2022-2023 GLE350, GLE450, GLE580, GLS450, GLS580, Maybach GLS600, AMG GLE53, AMG GLE63 S, and AMG GLS63 vehicles due to the rear door window trim bars potentially detaching from the vehicle while driving. Dealers will inspect and secure the rear window trim bars, as necessary, free of charge.
Lastly, there has been a recall for certain 2021-2023 C-Class, E-Class, S-Class, CLS, SL, GT, GLC, GLE, GLS, and G-Class vehicles due to the fuel pump potentially shutting down, which can result in a loss of drive power. Dealers will replace the fuel pump, free of charge.
In conclusion, while the 2021 Mercedes-Benz GLS580 has had some reported issues, Mercedes-Benz has issued recalls and updates to address these problems. However, it is essential to consider the below-average reliability of the GLE/GLS generation when purchasing this vehicle.
Is the Mercedes GLS reliable?
We expect the 2024 GLS to be less reliable than other new cars. This prediction is based on the similar GLE, plus the Mercedes brand scores.
What engine is in the 2021 Mercedes GLS?
Two models are offered—the six-cylinder GLS450 and the eight-cylinder GLS580—and both feature some hybridization. The GLS450's turbocharged 3.0-liter inline-six is silky smooth and good for 362 horsepower. The GLS580 is far more powerful, making 483 horsepower from its twin-turbocharged 4.0-liter V-8.
How safe is Mercedes GLS?
And that's a good thing: the GLE achieved the maximum five star rating when it was assessed in 2019. It achieved a 91% score in the adult occupant protection category; a rating that puts the Merc two percent ahead of the BMW X5 (a car which shares much with the X7).
What is the top speed of the GLS580?
