Buying a luxury SUV like the Mercedes-Benz GLE is a big decision. You want a reliable, comfortable vehicle that will last for years. But not every GLE model year is created equal. Some years are loved for their comfort and advanced features.
Others are known for costly problems and headaches. If you’re thinking about buying a used Mercedes GLE, it’s smart to know which years to avoid—and why.
This guide takes a deep dive into Mercedes GLE years to avoid, plus the best years to consider. You’ll learn about common issues, reliability data, and real-world owner experiences. Whether you’re new to luxury vehicles or you’ve owned Mercedes cars before, this article gives you the clear, practical advice you need to make a confident choice.
Understanding The Mercedes Gle
The Mercedes-Benz GLE sits in the midsize luxury SUV class. It replaced the old Mercedes M-Class in 2016. Since then, it’s become one of the brand’s best-selling SUVs. The GLE offers a mix of power, style, advanced technology, and family-friendly features. It comes in several versions, including the sporty GLE Coupe and high-performance AMG models.
But like any vehicle, the GLE’s reputation depends on the model year. Some years come with excellent reliability, while others are more likely to have expensive problems. Let’s look at what sets the GLE apart and why model year matters so much.
Mercedes Gle Generations
There are two main generations of the GLE so far:
- First Generation (W166): 2016–2019
- Second Generation (V167): 2020–present
The GLE was called the M-Class before 2016. If you’re considering a 2015 or earlier model, you’re actually looking at the final years of the M-Class, not the GLE.
Why Some Gle Years Are Best Avoided
Not every Mercedes GLE is the same when it comes to quality. Some years stand out for their reliability problems, expensive repairs, and frustrating issues. The main reasons to avoid certain years include:
- Engine problems: Issues like oil leaks, excessive oil consumption, or engine failure can lead to major costs.
- Transmission troubles: Rough shifting, delayed acceleration, or complete transmission failure have been reported.
- Electrical system faults: Problems with the infotainment system, sensors, or even total electrical failure are not rare.
- Air suspension failures: The GLE’s advanced suspension system can be comfortable, but it’s also complex and expensive to fix.
- High repair costs: Even minor issues can cost much more than average, especially after the warranty ends.
Some of these problems show up in owner complaints, while others are noted in recalls and technical service bulletins. Let’s explore exactly which GLE years to avoid—and the reasons behind those recommendations.
Mercedes Gle Years To Avoid
Based on data from sources like CarComplaints, NHTSA, owner forums, and repair shops, several GLE years stand out as models you should think twice about buying used.
2016 Mercedes Gle
The first year of the GLE nameplate is also one of its most problematic. Many owners report serious issues with:
- Transmission: Sudden jerking, delayed shifting, and even total transmission failure.
- Electrical system: Infotainment glitches, warning lights, and electrical system errors.
- Engine: Excessive oil consumption and engine warning lights.
The 2016 GLE was part of a major redesign. As with many first-year models, Mercedes had not yet worked out all the kinks. Repair bills for these problems can be extremely high, especially for the transmission.
Real-world Example
One owner reported needing a full transmission replacement at under 70,000 miles—a repair costing over $7,000. Many others mention persistent electrical faults that dealers struggled to fix.
2017 Mercedes Gle
The 2017 model fixed some earlier problems, but not all. It still suffers from:
- Electrical issues: Malfunctioning sensors, warning lights, and infotainment failures.
- Air suspension failures: The AIRMATIC system can leak or fail, leading to a harsh ride and expensive repairs.
While reliability scores improved slightly, the 2017 GLE was still below average for the class. Air suspension repairs often cost $2,000 or more.
2018 Mercedes Gle
This year is less problematic than 2016 and 2017, but still has some issues:
- Electronics: Owners report backup camera failures, navigation problems, and sensor errors.
- Engine: Some GLE 350 models show excessive oil use and occasional stalling.
The 2018 GLE also saw several recalls for airbag and backup camera problems, which can be a concern for safety and reliability.
2020 Mercedes Gle
The start of the second generation brought a fresh design and new tech, but also new issues:
- Infotainment system: The new MBUX system is powerful but has many glitches—screen freezes, rebooting, and Bluetooth failures are common.
- Sunroof leaks: Water leaks from the panoramic sunroof have led to damaged interiors and electrical systems.
- Build quality: Some owners report rattles, misaligned panels, and loose trim pieces.
Because it’s the first year of a major redesign, the 2020 GLE is more likely to have “teething problems. ” These can be especially frustrating given the car’s price tag.
2021 Mercedes Gle
Many of the 2020 GLE’s problems carried over. The 2021 GLE still has:
- MBUX software bugs: Voice controls, navigation, and smartphone integration often freeze or crash.
- Air suspension complaints: The ride can be unpredictable, and repairs remain costly.
- Electrical issues: Some owners report complete electrical shutdowns, especially after heavy rain or leaks.
While later model years have seen improvements, the 2021 GLE remains riskier than average, especially if buying used.

Key Problems With Mercedes Gle Years To Avoid
Let’s break down the most common issues in the GLE years you should avoid. Understanding these problems can help you make a better decision and avoid expensive surprises.
Transmission Failures
Some GLEs (especially 2016) suffer from transmission problems such as:
- Hard or delayed shifting
- Transmission slipping or jerking
- Complete failure, often before 80,000 miles
These issues often require a full rebuild or replacement, costing $5,000 or more. If you notice rough shifting during a test drive, walk away.
Electrical System Faults
The GLE’s complex electronics can lead to:
- Random warning lights on the dashboard
- Backup camera and sensor failures
- Infotainment freezes and Bluetooth disconnects
These problems may seem minor but can be very frustrating and expensive to diagnose. Electrical gremlins often come back even after repairs.
Air Suspension Issues
The AIRMATIC air suspension is great for comfort but can fail in older or high-mileage models. Symptoms include:
- Uneven ride height
- “Suspension failure” messages
- Bouncing or harsh ride
Repairs can run from $1,500 for a single air strut to $6,000 for a complete system overhaul.
Engine Problems
Some GLEs (especially 2016–2018) have:
- Excessive oil consumption
- Oil leaks
- Engine stalling or loss of power
These issues can damage the engine over time and cost thousands to fix.
Sunroof And Water Leaks
The 2020 GLE introduced a panoramic sunroof with a known leak problem. Water can enter the cabin, damaging carpets, electronics, and even causing mold. Fixing a leak can require removing the headliner and replacing seals—an expensive job.
What Makes A Gle Year Reliable?
Not all GLEs are trouble-prone. The best years have these traits:
- Proven technology: Later models in a generation tend to be more reliable.
- Fewer recalls: Reliable years have fewer safety or mechanical recalls.
- Lower owner complaints: Fewer problems mean happier owners.
- Updated electronics: Software bugs are fixed in later years.
Insider Tip
Don’t just go by mileage. A low-mileage GLE from a problematic year can still develop issues. A well-maintained GLE from a better year is usually a safer bet.

Practical Advice For Buying A Used Gle
Choosing the right GLE year is only part of buying a used luxury SUV. Here’s how to minimize risk and get the best experience:
- Check for a full service history. Luxury cars need regular maintenance. Walk away if service records are missing.
- Have a pre-purchase inspection done by a Mercedes specialist. This can reveal hidden issues.
- Look for certified pre-owned (CPO) models. CPO GLEs come with extended warranties and have been inspected by Mercedes.
- Avoid base models with few options. Higher trims often have more reliable features and better resale value.
- Test all electronics and features during your test drive. If anything doesn’t work, repairs will be expensive.
- Research recall history for the exact VIN (vehicle identification number).
Common Mistakes To Avoid
Many buyers new to Mercedes make these mistakes:
- Buying the cheapest GLE they find, even from a risky year
- Ignoring warning lights or “small” problems during a test drive
- Assuming dealer repairs will be cheap because the car is “only a few years old”
- Skipping the pre-purchase inspection to save money (often costs more later)
How The Gle Compares To Other Luxury Suvs
You might wonder how the GLE’s reliability stacks up against similar SUVs like the BMW X5 or Audi Q7. Here’s a quick comparison:
| Model | Common Issues | Reliability (1–5) | Average Repair Cost |
|---|---|---|---|
| Mercedes GLE | Transmission, electronics, air suspension | 3 | $1,500–$6,000 |
| BMW X5 | Cooling system, air suspension, electronics | 3 | $1,400–$5,800 |
| Audi Q7 | Timing chain, electronics, brakes | 3 | $1,300–$5,500 |
While all luxury SUVs come with risks, the GLE is known for more air suspension and infotainment problems than its rivals. However, Mercedes parts and labor can also be more expensive, especially outside of warranty.

How To Spot A Problematic Gle Before You Buy
Here are some practical steps you can take to avoid buying a trouble-prone GLE:
- Ask for maintenance records. Walk away if the seller can’t provide them.
- Check for open recalls at your local Mercedes dealer or on the NHTSA website.
- Listen for suspension noises. Clunks or rattles on bumps could mean expensive repairs ahead.
- Test all electronics—radio, navigation, backup camera, power seats, and all lights.
- Inspect for water leaks. Check the headliner, carpets, and trunk for damp spots or mold smell.
- Look for uneven tire wear. This can signal suspension or alignment issues.
If the car passes all these checks and is not from a “year to avoid,” you can buy with more confidence.
Non-obvious Insights Most Buyers Miss
- Software updates matter: Many GLE electronics problems are software-related. Ask if the car has received all official software updates from Mercedes.
- Warranty coverage is limited: The standard Mercedes warranty is 4 years/50,000 miles. After that, even small repairs can be costly. Consider buying an extended warranty, especially for 2020–2021 models.
- Parts availability can be an issue: For some problematic years, certain parts (like MBUX screens or air suspension struts) may be on backorder. This means long repair times, not just high costs.
Should You Ever Buy A Gle From A “bad” Year?
It’s possible to find a well-maintained GLE from a problematic year at a good price. But you must go in with your eyes open:
- Budget for repairs: Save extra money in case major issues show up.
- Get the car checked by a Mercedes specialist before buying.
- Try to find a car with warranty coverage remaining, or buy a third-party warranty.
If you need rock-solid reliability, you’re better off choosing a GLE from a more dependable year, even if it costs a bit more.
Is Maintenance More Important Than Model Year?
A well-maintained GLE from a riskier year can sometimes be better than a neglected car from a “good” year. Always check:
- Oil change history (should be every 10,000 miles or less)
- Transmission service records
- Suspension and brake work
Regular maintenance is crucial for a luxury SUV with advanced features.

What If You Already Own A Gle From A Problem Year?
If you already own a GLE from one of the riskier years, here’s how to protect your investment:
- Follow the maintenance schedule closely. Never skip or delay service.
- Keep all receipts and records. This helps with future resale and warranty claims.
- Address warning lights immediately. Small problems can quickly become big, expensive ones.
- Stay updated on recalls. Some repairs may be covered by Mercedes, even out of warranty.
Are Mercedes Gles Expensive To Repair?
Yes, the GLE is more expensive to maintain than non-luxury SUVs. Typical repair costs include:
- Oil changes: $200–$400
- Brake pads and rotors: $800–$1,500
- Air suspension repair: $1,500–$6,000
- Transmission replacement: $6,000–$8,500
If you’re used to owning Hondas or Toyotas, the costs may surprise you. This is why choosing the right year and a well-cared-for vehicle is so important.
Where To Find Reliable Gle Information
For up-to-date recall and reliability data, you can visit the official NHTSA website. Many owner forums and Mercedes enthusiast sites also share real-world experiences, but always verify with official sources.
Final Thoughts: Making The Right Choice
The Mercedes GLE is a luxurious, high-tech SUV with plenty of style and comfort. But not every year is equally reliable. If you’re buying used, avoid the 2016, 2017, 2018, 2020, and 2021 models unless you find one with a flawless history and warranty.
For the best ownership experience, focus on the 2019, 2022, or 2023 GLE. These years offer fewer headaches, better technology, and stronger resale value. Always do your research, get a professional inspection, and make sure the car has a clean maintenance record.
By following these tips, you’ll enjoy the benefits of Mercedes luxury without the stress of constant repairs.
