Should You Buy the 2024 Mercedes-Benz Gls?
The 2024 Mercedes-Benz GLS offers an unparalleled blend of luxury, technology, and comfort, making it a highly desirable full-size SUV. While initial build quality is exceptional, its advanced and complex systems, particularly the 48V mild-hybrid and air suspension, introduce a moderate long-term risk profile for future owners. This is a vehicle you can confidently buy, provided you understand and budget for the sophisticated maintenance and potential high repair costs associated with its cutting-edge engineering.
The 2024 Mercedes-Benz GLS is an outstanding luxury SUV that delivers on its promise of opulence and performance. However, due to its inherent technological complexity, particularly the 48V mild-hybrid system and air suspension, long-term ownership carries a 'Proceed with Caution' label. This isn't a recommendation…
Best Model Years
For the X167 generation (2020+), focus on models with complete service history and, ideally, a transferable extended warranty. There isn't a 'best' 2024 model year as it's the current one, but facelift improvements (2024+) often refine earlier issues.
Years to Avoid
No specific years to avoid within the 2024 model year. For the X167 generation, the very earliest 2020 models might have a higher incidence of initial software bugs, but most have been addressed via updates.
Biggest Strengths
- Exceptional build quality and premium materials
- Sophisticated powertrain with smooth performance
- Advanced safety and driver-assistance systems
Top Risk Areas
The systems that tend to fail first on the 2024 Mercedes-Benz Gls, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
Issues with the 48V battery, voltage converter, or integrated starter-generator (ISG) can lead to various electrical faults, engine shutdowns, or 'limp home' mode. This system is critical for many vehicle functions.
Over time, air springs can develop leaks, suspension struts may fail, or the air compressor and level sensors can malfunction. This results in an uneven ride height, poor ride quality, or complete suspension collapse.
Software glitches, system freezes, unresponsive screens, or sensor failures within the extensive MBUX infotainment and driver-assistance systems. Issues can range from minor annoyances to critical system malfunctions.
2024 Mercedes-Benz Gls Mileage Danger Zones
The mileage windows when the 2024 Mercedes-Benz Gls most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Initial Adjustment & Software Zone
At this mileage, any early manufacturing quirks, software bugs for the MBUX system, or minor electrical gremlins are likely to surface and should be addressed under warranty.
Pre-Emptive Inspection Zone
This mileage marks a crucial point to closely inspect wear items and proactively assess the health of complex systems like the 48V mild-hybrid and air suspension before potential failures occur.
Elevated Component Risk Zone
As the vehicle approaches six-figure mileage, the probability of major component failures, especially with the air suspension and 48V system, significantly increases, requiring substantial budget for repairs.
High Risk & Major Overhaul Zone
Beyond this point, expect significant investment in maintaining the vehicle. Multiple high-cost components are likely to require replacement, and the risk of cascading failures rises without consistent preventative care.
