Mercedes-benz Gls450 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 Mercedes-benz Gls450 problems

Based on complaints from owners of the Mercedes-Benz GLS450, several common problems have been reported:

  1. Water Damage: Owners have experienced water entering the car and wetting the floor, leading to damage to electronics located under the seats. This issue has resulted in significant repair costs and, in extreme cases, total loss of the vehicle.
  2. Running Board Design: Some owners have raised concerns about the running board being too narrow, posing safety risks, especially in snowy or icy conditions. The narrow design has been reported as potentially dangerous.
  3. Electrical Issues: Complaints include various electrical problems, such as issues with the multimedia system (MBUX), malfunctioning control units, and cracking seat materials. These electrical issues have led to inconvenience and costly repairs for owners.
  4. Tire Wear: Owners have reported premature tire wear, with the need for tire replacements at low mileage intervals, such as before 10,000 miles. This has raised concerns about the longevity and quality of the tires equipped on the GLS450.
  5. Tech Glitches: Some owners have experienced occasional technical glitches, including seat reset points and lane-keep aid malfunctions. These glitches, although sporadic, have highlighted minor technological imperfections in the vehicle.
  6. Fuel Tank Location: A minor complaint involves the fuel tank being located on the passenger side, which some owners find inconvenient and potentially less safe during refueling compared to having it on the driver's side.

These reported problems indicate a range of issues that Mercedes-Benz GLS450 owners have faced, from water damage affecting electronics to concerns about safety features like the running board design. Addressing these issues can help improve the overall ownership experience and satisfaction with the vehicle.
