What the Experts Say About GLS Reliability Ratings

When evaluating the long-term reliability of any vehicle, it’s wise to look at the data and ratings from respected third-party experts. For the Mercedes-Benz GLS, these outside sources paint a fairly positive picture in terms of predicted dependability.

Consumer Reports, one of the most well-known authorities on vehicle reliability, gives the GLS impressive scores across multiple model years. The 2020 GLS earned a 5 out of 5 rating for predicted reliability, while the 2019 model received a still-strong 4 out of 5. Older generations like the 2016 and 2017 GLS also scored 4s from CR’s data analysis.

J.D. Power’s Vehicle Dependability Study (VDS) shows similarly encouraging results. The GLS earned an 83/100 score in the 2022 VDS, putting it well above the industry average for models at the three-year ownership mark. This strong rating indicates most GLS models should provide reliable service through at least 60,000 miles or so.

Compared to key rivals in the full-size luxury SUV segment, the GLS tends to rate higher for predicted reliability. The Lincoln Navigator, BMW X7, and Cadillac Escalade have all scored lower than the Mercedes in Consumer Reports and J.D. Power studies over the past several years. While no vehicle is perfect, the data suggests the GLS delivers above-average reliability for this class of vehicle.


Long-Term GLS Owner Reviews & Experiences

To get a real-world look at Mercedes-Benz GLS reliability, we turned to online owner forums and social media groups. Here, current drivers share their candid experiences and issues with the luxury SUV after racking up higher mileage.

Overall, the sentiment from owners with 50,000 miles or more on their GLS is quite positive. Many report minimal issues besides routine maintenance and wear items during the first 75,000-100,000 km. Common complaints include squeaky brakes around 30,000 miles and occasional electronic glitches with the COMAND infotainment system.

“My 2016 GLS450 has been rock solid at 85,000 miles. Only real issues have been a leaking rear differential seal and the air suspension compressor going out around 70k miles. Otherwise it’s been smooth sailing and still feels super solid on the road.” – GLS Owner, Toronto

Once past the 100,000 mile mark, more significant repairs do start to pop up for some unlucky owners. Air suspension failures, oil leaks, and transmission problems have all been reported, though they don’t seem widespread. Proper maintenance seems to be the key to GLS longevity.

“I’m at 115,000 km in my 2017 GLS550 and it’s been a great vehicle overall. The air shocks were replaced under warranty at 90k km which was a costly repair. Other than that, just normal stuff like brakes and tires so far. It still drives like new.” – Vancouver GLS Owner

While the occasional lemon exists, the majority of long-term GLS owners report being very satisfied with their luxury SUV’s reliability when properly cared for. With reasonable expectations around maintenance costs, the GLS seems to deliver robust build quality and longevity.


The Most Common Problems with High Mileage GLS Models

While the GLS enjoys a solid reputation for reliability, no vehicle is perfect – especially as higher mileage examples start to rack up the kilometers. Based on reports from owners and mechanics, a few common problem areas tend to crop up on GLS models with 60,000 miles (96,000 km) or more.

One of the biggest concerns is air suspension failure. The GLS’s advanced AIRMATIC air suspension provides an exceptionally smooth ride and adjustable height settings. However, the system’s air compressors and struts are prone to leaking as they age. Many owners report having to replace failed components around 75,000-100,000 miles, at costs often exceeding $2,000.

Oil leaks from the rear main seal are another frequently cited issue on higher mileage GLS models. While not a huge repair, these leaks can cause the engine to burn through oil rapidly if left unchecked. Most mechanics recommend resealing the rear main around 100,000 miles as preventative maintenance.

The GLS’s advanced COMAND infotainment system has proven glitchy over time as well. Owners complain of frozen screens, unresponsive inputs, and various electronic bugs setting in after 4-5 years of use. While usually just an annoyance, complex issues may require an expensive control module replacement.

Finally, many GLS drivers note excessive brake noise and warped rotors developing around the 30,000-mile mark. While brake life is on par with other luxury SUVs, the GLS’s weight and performance capabilities place high demands on the brake system. Budget for premium brake pad and rotor replacements every 40,000 miles or so.


Mercedes GLS Maintenance Costs in Canada

While the Mercedes-Benz GLS delivers impressive luxury and capabilities, it’s no secret that maintaining this high-end SUV comes at a premium cost for Canadian owners. From routine service items to more significant repairs, being prepared for these expenses is crucial when budgeting for long-term GLS ownership.

Let’s start with the basics: a simple oil change at the Mercedes-Benz dealership will typically run you around $150 or more in most parts of Canada. This cost can add up quickly when following the recommended service intervals. Tire rotations and other minor services will tack on additional fees as well.

When it comes time for more extensive maintenance, Canadian GLS owners should be prepared to open their wallets. A complete brake job, including pads and rotors for all four wheels, can easily cost between $800 to $1,200 or more depending on the province and labor rates. Premium tires for the GLS’s large wheel sizes can also set you back $1,000+ for a full set.

Some of the bigger-ticket items that GLS owners may face include repairs to the complex air suspension system. Replacing a failed air suspension compressor can cost upwards of $2,000 once parts and labor are factored in. Electronic gremlins, though relatively rare, can also result in hefty bills if major control modules or wiring harnesses need replacement.

As a general guideline, most experts recommend budgeting $1,500 to $2,000 per year for unexpected repairs and maintenance on a GLS once it’s out of the initial warranty period. This figure can fluctuate based on driving conditions, but it’s a reasonable estimate for the costs of keeping a GLS in top operating condition long-term.


Does the Air Suspension Hurt Long-Term GLS Reliability?

One of the most commonly discussed potential trouble spots for the Mercedes-Benz GLS is its air suspension system. While air suspension provides an ultra-smooth ride and adjustable height capabilities, the components are more complex and expensive to repair than traditional steel springs.

Across GLS owner forums, air suspension failure emerges as one of the top repair issues once these luxury SUVs surpass 60,000-80,000 miles (100,000-130,000 km). Leaking air lines or compressor pumps force many owners to replace the entire air suspension system at great expense.

While the air suspension problems don’t impact driving safety, they can severely degrade ride quality if not addressed. Owners report the GLS will sag or lean excessively to one side when the air suspension begins failing. Replacing pumps, lines, and air bags can cost $2,000-$4,000 at the Mercedes-Benz dealer in parts and labor.

That said, many GLS owners feel the superior comfort and adjustability of air suspension is worth the potential long-term costs. By properly maintaining the system and budgeting for eventual repairs, they’re able to enjoy the benefits for years before issues arise. Additionally, extended warranty coverage can help offset air suspension repair costs.


The Benefits of Buying CPO for the GLS

For buyers concerned about long-term repair costs, opting for a certified pre-owned (CPO) Mercedes-Benz GLS can provide valuable peace of mind. Every CPO GLS from Mercedes undergoes a rigorous 165-point inspection and reconditioning process to ensure it meets like-new standards. More importantly, it comes backed by extended warranty coverage that can save you thousands in unexpected repair bills.

A CPO GLS includes the remainder of the original 4-year/80,000 km new vehicle warranty, plus an additional 2 years/40,000 km of comprehensive coverage. This covers virtually every component of the vehicle, from the engine and transmission to the electronics and air suspension. For high-mileage GLS models, this warranty can provide thousands in coverage remaining.

Mercedes’ CPO program also includes 24/7 roadside assistance, trip interruption coverage, and the ability to transfer the warranty to a new owner. You’ll pay a premium over a traditional used GLS, but the warranty alone can easily offset that cost with just one major repair down the road.

For Canadian families considering a pre-owned GLS, opting for a CPO model is one of the smartest ways to mitigate long-term repair risk. The warranty provides invaluable coverage during the years when larger maintenance issues tend to arise. It’s the closest thing to new car peace of mind, at a substantial savings over brand new.


GLS Reliability Compared to Other Luxury SUVs

When shopping for a full-size luxury SUV, the Mercedes-Benz GLS faces stiff competition from rivals like the Lincoln Navigator, Cadillac Escalade, BMW X7, and Lexus LX. While all these vehicles offer premium features and performance, their reliability reputations vary widely.

According to data from Consumer Reports and J.D. Power, the Mercedes GLS consistently outperforms most of its key competitors in predicted reliability ratings and quality surveys. The Lincoln Navigator and Cadillac Escalade, in particular, tend to score below average for the segment.

The BMW X7 represents the GLS’s closest rival in terms of reliability. BMW’s ratings fluctuate year-to-year but generally fall just behind Mercedes. Lexus holds an edge over both German brands when it comes to long-term dependability.

Where the GLS stands out is in avoiding some of the recurring problem areas that plague American and BMW luxury SUVs. Issues like transmission shudder, electrical gremlins, and cheap interior materials are more common on the Navigator, Escalade, and X7. The GLS’s stellar build quality and proven powertrain designs give it a leg up.

It’s also worth noting that while all these high-end SUVs come with hefty maintenance costs, the GLS’s fixed pricing schedules and strong dealer network make costs more predictable over time. American brands like Lincoln and Cadillac can be less consistent.

For Canadian luxury SUV buyers who prioritize reliability alongside performance and luxury, the Mercedes-Benz GLS presents a compelling overall package compared to the competition.


Long-Term Mercedes Owner Satisfaction & Brand Loyalty

When it comes to overall customer satisfaction and brand loyalty, Mercedes-Benz performs exceptionally well among long-term owners. According to industry surveys and data, Mercedes enjoys some of the highest rates of repeat buyers and brand advocates in the luxury vehicle segment.

J.D. Power’s annual Customer Service Index consistently ranks Mercedes among the top luxury brands for dealer service satisfaction. Their data shows that over 60% of Mercedes owners return to purchase another vehicle from the brand after 3-5 years of ownership.

Similarly, Consumer Reports’ owner satisfaction ratings reveal that Mercedes drivers tend to be very pleased with their vehicles after several years. Factors like comfort, driving experience, and perceived quality and reliability all rate highly. This positive long-term ownership experience translates into impressive brand loyalty.

Within the large luxury SUV segment specifically, the Mercedes-Benz GLS tends to deliver high owner satisfaction scores relating to its spacious interior, smooth ride, and capable performance. Provided they keep up with scheduled maintenance, GLS owners frequently report being happy with their purchase decision even after 100,000 miles or more.

Ultimately, Mercedes has cultivated a fiercely loyal customer base by delivering a complete luxury vehicle ownership experience that keeps drivers satisfied long after the new car smell wears off. The GLS encapsulates this long-term appeal with its combination of premium appointments, spaciousness, and proven long-term quality and reliability.


What GLS Problems Are Still Covered Under Warranty?

If you’re considering purchasing a new Mercedes-Benz GLS or a certified pre-owned model, it’s important to understand what’s covered under the various warranty options. The GLS comes with Mercedes’ standard new vehicle warranty, which provides comprehensive coverage for the first few years of ownership.

With a new GLS, you’ll receive a 4-year/80,000 km basic warranty that covers most components against defects in materials or workmanship. There’s also a 5-year/100,000 km powertrain warranty for the engine, transmission, and drivetrain. Finally, Mercedes includes corrosion coverage for 4 years with no mileage limit.

If you opt for a certified pre-owned (CPO) GLS from Mercedes, you’ll still get impressive warranty coverage. CPO vehicles come with a comprehensive warranty that covers most components for 6 years from the original service date or 120,000 km, whichever comes first. The powertrain warranty extends to 6 years/120,000 km as well.

These warranties should provide peace of mind against many of the common GLS issues mentioned earlier. Problems like air suspension failures, oil leaks, electronics glitches, and brake issues would likely be covered under the new vehicle or CPO warranty, saving you from expensive repair bills.

It’s worth noting that wear items like tires, brake pads, and wiper blades aren’t covered by the standard warranties. You’ll also be responsible for routine maintenance costs. But for any major defects or failures, Mercedes’ warranties have you covered during those initial years of ownership.


Tips for Getting the Most Reliable GLS Possible

While the Mercedes-Benz GLS is a well-built luxury SUV overall, there are some steps savvy shoppers can take to maximize their chances of getting an ultra-reliable example. Here are our top tips:


Choose the Right Engine – The turbocharged 3.0L V6 in the GLS 450 models has proven to be the most dependable engine option. Avoid the twin-turbo V8 if long-term reliability is your top priority, as it adds complexity and heat. The GLS 450 V6 offers plenty of power for most buyers.

Stick to a Stock Configuration – The more options and packages you add, the more potential points of failure. Sticking to a lightly-optioned GLS with basics like a premium sound system and driver assistance features is wise. Skipping the fancy air suspension also eliminates one potential weak point.

Buy Certified Pre-Owned (CPO) – Mercedes’ CPO program is excellent, providing comprehensive coverage for the powertrain, electronics, air suspension, and more. A low-mileage CPO GLS makes a smart buy, as you’ll be covered for any issues during the warranty period.

Negotiate an Extended Warranty – Even if buying new, consider paying for an extended warranty from Mercedes that provides comprehensive coverage for 5-7 years or 120,000 km. This virtually eliminates any major out-of-pocket repair costs.

Follow the Maintenance Schedule – Keeping the GLS properly maintained according to Mercedes’ recommended service intervals is crucial. Use high-quality synthetic oils and OEM parts/filters. Having full service records will also help resale value down the road.


Should You Buy an Extended Warranty for the GLS?

When it comes to purchasing an extended warranty for the Mercedes-Benz GLS, the decision ultimately depends on your personal preferences and budget. While the GLS is generally considered a reliable luxury SUV, it’s still a complex vehicle with numerous components that may require costly repairs as it ages.

An extended warranty can provide peace of mind by covering a significant portion of repair costs beyond the standard factory warranty period. This can be particularly beneficial for those who plan to keep their GLS for an extended period or rack up high mileage. Major repairs, such as replacing the air suspension system or addressing electronics issues, can easily cost thousands of dollars out of pocket.

However, extended warranties come at an additional cost, which can range from a few thousand dollars to well over $5,000, depending on the coverage level and term length. It’s essential to carefully review the terms and conditions of any extended warranty to understand what is and isn’t covered, as well as any deductibles or limitations.

For those who are diligent about routine maintenance and have a trusted, reputable independent mechanic, the cost of an extended warranty may not be justifiable. Additionally, if you plan to trade in or sell your GLS before reaching higher mileage, the extended warranty may not provide significant value.

Ultimately, the decision to purchase an extended warranty for the Mercedes-Benz GLS should be based on your budget, driving habits, and personal risk tolerance. It’s a personal choice that can provide added protection against unexpected repair costs but also comes with an additional upfront investment.


GLS Reliability Pros and Cons – The Final Verdict

Yes, insuring a GLS in Canada is quite expensive due to its high purchase price, status as a common luxury/performance target for thieves, and high repair costs. Owners can expect to pay $250-$400 per month for basic coverage depending on their age, driving history, location and other factors. The high-output AMG models cost even more to insure due to their power and desirability. Reducing risks through bundling, selecting higher deductibles and asking about security discounts can lower costs. But there’s no getting around the reality that as a $100k+ luxury German SUV, the GLS hits the most painful segments for insurance premiums.

A set of four factory-spec all-season tires for the 22-inch GLS wheels costs around $1600 at Canadian tire shops. Stepping up to higher-end grand touring summer or winter tires pushes the price closer to $2000 installed. The staggered setup with two different front/rear sizes means buying four new tires at once is mandatory for proper functionality too. While cheaper aftermarket options exist, most owners stick to premium name brands like Michelin or Continental to maximize ride comfort and traction. Considering the GLS’s curb weight exceeds 5,700 pounds, cutting corners on tires is risky. So buyers should anticipate high replacement costs when budgeting long-term.

In Canada, a few common GLS complaints include:


– Expensive scheduled maintenance at dealerships

The GLS also resists the tail-wagging tendencies some trucks suffer from in slippery conditions. Combined with all-weather composure from the adjustable air suspension, the GLS gives owners reassuring confidence to tackle northern winters in style and safety.

Yes, the Mercedes GLS offers excellent accommodations for taller drivers thanks to its generous headroom and legroom dimensions. Front seats feature extensive adjustability, including thigh support extension to fit long legs comfortably on long drives. Steering wheel and pedal placement also benefit those over 6 feet tall without compromising smaller passengers’ positions too much. Optional luxury front seats take comfort up another notch as well with additional side bolsters and heating functions. With large side mirrors and 360-degree parking cameras, GLS visibility excels too for avoiding blind spots. Overall, Mercedes goes the extra mile to make the GLS cockpit welcoming for larger statures.
