Analysis

What Problems Does the 2019 Mercedes-Benz GLS-Class Have?

Frequently reported problems for the 2019 Mercedes-Benz GLS-Class, and the preceding GLS generation, often revolve around the air suspension system. Failures can lead to uneven ride height, sagging, or complete system failure, which can be costly to repair. The infotainment system, specifically the COMAND system, can sometimes experience glitches, freezes, or connectivity issues. Some owners have also reported issues with the sensors and electronics associated with the driver-assistance features, leading to false alerts or system malfunctions.
While the 2019 model year itself didn't have a significant number of unique recalls compared to prior years, it's crucial to check the NHTSA (National Highway Traffic Safety Administration) website for any safety recalls that may have been issued. It is also important to check the vehicle history report for any prior repair records. Long-term reliability can be a concern due to the complexity of the vehicle's systems and components. Regular maintenance, following the manufacturer's recommended service schedule, and addressing issues promptly can help mitigate some of these risks. The cost of ownership should be considered, as repairs on luxury vehicles like the GLS-Class tend to be more expensive than those on mainstream models.

How long will the 2019 Mercedes-Benz GLS-Class last?

With proper maintenance, a 2019 Mercedes-Benz GLS-Class can be expected to last for 150,000 to 200,000 miles or 10-15 years. Average annual mileage typically falls between 12,000 and 15,000 miles. Long-term durability hinges on consistent maintenance, particularly fluid changes and addressing any emerging issues promptly. The air suspension system remains a potential long-term weakness. Electronics can also become problematic as the vehicle ages. Regular servicing and preventative maintenance are crucial to maximizing its lifespan.

2019 Mercedes-Benz GLS-Class Insurance

Insurance for a 2019 Mercedes-Benz GLS-Class is moderately priced, reflecting its status as a Sport Utility Vehicle with strong safety ratings and
reasonable repair costs.

How Does the 2019 Mercedes-Benz GLS-Class Compare to Other Sport Utility Vehicle?

The 2019 Mercedes-Benz GLS-Class competes with other luxury three-row SUVs like the BMW X7, Audi Q7, Cadillac Escalade, and Land Rover Range Rover. In terms of performance, the GLS offers competitive engine options, though some rivals may offer more powerful variants. Feature-wise, the GLS is well-equipped, but competitors often have comparable or more advanced technology. Reliability is an area where the GLS can fall slightly behind some rivals, particularly the Audi Q7. The Cadillac Escalade offers significantly more cargo space.

Price-wise, the GLS is positioned in the higher end of the segment, though the actual difference to similarly equipped rivals is often minimal. A potentially better alternative depending on priorities, is the BMW X7, which offers a more modern interior and refined driving experience, but may not offer as much cargo volume. The Audi Q7 can be a similarly luxurious and refined option with superior reliability, but it lacks the raw power of the V8 GLS 550.

The Lincoln Navigator offers a more luxurious interior with very spacious dimensions and is a strong contender for its price point and feature set. The Range Rover offers off-road ability which the GLS is not focused on, although it may also have comparable reliability concerns.

Final Verdict: Is the 2019 Mercedes-Benz GLS-Class a Good Sport Utility Vehicle?

The 2019 Mercedes-Benz GLS-Class is ideal for families seeking a luxurious and spacious three-row SUV with a prestigious badge. It offers a comfortable ride, powerful engine options, and a well-appointed interior. Whether it's worth buying depends on individual priorities and budget. A used 2019 GLS can be a good value, but it's essential to have it thoroughly inspected by a qualified mechanic before purchasing, paying close attention to the air suspension and infotainment system. Consider the GLS 450 for a balance of performance and fuel economy. If budget is not a concern, and power is preferred, a GLS 550 is suitable. Ensure regular maintenance is factored into ownership.
