Short answer: yes, the Mercedes-Benz GLE 350 is a high-maintenance SUV compared with normal brands (Toyota, Honda, etc.), but it is about average for a mid-size luxury SUV.
It has fairly good reliability scores in some places, but parts and labor are expensive, and long-term ownership costs are clearly higher than the market average.
What “High Maintenance” Actually Means Here
When people call the GLE 350 “high maintenance”, they usually mean:
- Higher yearly service costs than mainstream brands.
- Expensive parts (brakes, suspension, electronics, etc.).
- Costly repairs once the SUV is older and out of warranty.
The question is not “does it break every week?” but rather “how much money will I spend keeping this thing healthy?”
Hard Numbers: GLE 350 Long-Term Maintenance Costs
A big ownership cost study from CarEdge estimates that a Mercedes-Benz GLE 350 will cost about $15,230 for maintenance and repairs in the first 10 years.
They also note:
- This is about $2,777 more than the average luxury SUV over the same time.
- There is a 44% chance the GLE 350 will need a major repair (over $500) in its first 10 years, which is about 5% worse than similar vehicles.
So compared with other luxury SUVs, the GLE 350 is slightly more expensive and slightly more likely to need a big repair. Compared with everyday cars, it is definitely on the pricey side.
Reliability vs Maintenance Cost
RepairPal / CarMax View: Above-Average Reliability
RepairPal data quoted by CarMax gives the Mercedes-Benz GLE 350 a reliability rating of 4 out of 5, described as “Above Average”, and ranks it 9th out of 29 luxury midsize SUVs.
That means it does not break as often as some might expect for a big, heavy, tech-filled SUV.
Consumer Reports View: Below-Average Predicted Reliability
Consumer Reports, which looks at owner surveys, expects the 2024–2025 GLE to be less reliable than the average new car based on recent model data.
So:
- Some data (RepairPal) says GLE 350 reliability is above average for luxury SUVs.
- Other data (Consumer Reports) says the GLE line is below the average new car overall.
Both can be true: luxury SUVs as a group are less reliable than simple cars, and inside that group the GLE can still be mid-pack or slightly better.
Typical Yearly Maintenance Costs
Mercedes service is not cheap. For the brand as a whole, one dealer’s guide shows typical pricing like:
- Service A: starts around $350+.
- Service B: roughly $820–$1,290 depending on model.
- Oil change: around $250+.
In their sample of models, mid-size Mercedes SUVs such as the ML 350 and GLK 350 showed average annual maintenance costs of about $1,185–$1,407, and the GLE 350 slots in the same general band.
CarEdge’s breakdown for the GLE 350 specifically shows estimated annual maintenance/repair costs climbing from about $621 in year 1 to over $2,200 by year 10, as the SUV ages.
Service Schedule: How Often Will You Be at the Workshop?
For a typical GLE 350:
- Service A: around 10,000 miles or 1 year the first time, then every 20,000 miles or 2 years.
- Service B: roughly every second visit, with more checks and replacements (and a bigger bill).
On top of that, expect:
- Brake pads and discs every few years depending on driving style.
- Tyres for a heavy SUV (not cheap, especially on big wheels).
- Occasional suspension and electronic repairs as the car ages.
Many owners report $1,000+ years once out of warranty for a mix of maintenance and random fixes.
Real-World Example: When Things Go Really Wrong
An extreme case from US news recently described a GLE 350 owner who was hit with a $40,000 engine replacement bill after a catastrophic failure just out of warranty, allegedly linked to oil issues.
This kind of disaster is not typical, but it shows how:
- Big failures on a luxury SUV can cost tens of thousands without warranty cover.
- Staying on top of oil changes and warranty status is very important with a GLE 350.
Most owners will never face that kind of bill, but even “normal” repairs can be painful compared with cheaper brands.
Is the GLE 350 High Maintenance Compared to Other Cars?
Versus Normal Brands (Toyota, Honda, etc.)
Compared with a regular mid-size SUV from a non-luxury brand:
- Yes, the GLE 350 is high maintenance.
- Yearly costs are often several hundred to a thousand dollars higher.
- Parts and labor are much more expensive.
Versus Other Luxury Midsize SUVs
Compared with rivals like BMW X5, Audi Q7, Volvo XC90:
- The GLE 350’s reliability is rated above average inside the luxury segment in some sources.
- Long-term costs are slightly higher than average for luxury SUVs.
- So it is high maintenance in general, but not wildly worse than its peers.
What Drives GLE 350 Maintenance Costs Up?
A few key things:
- Complex tech: big infotainment screens, driver aids, and plenty of electronics mean more potential issues and time on diagnostic machines.
- Premium parts: high-end brakes, tyres, and suspension components cost much more than economy-car parts.
- Dealer labor rates: Mercedes dealers charge premium hourly rates; even simple jobs add up quickly.
- Heavy vehicle: the GLE is large and heavy, which wears tyres and brakes faster than a small car.
How to Keep GLE 350 Maintenance Costs Under Control
You cannot turn a GLE 350 into a cheap-to-run car, but you can stop costs from getting silly.
1. Use a Good Independent Mercedes Specialist
- Once the warranty ends, a respected independent Mercedes shop can often do the same work for less.
- They usually have the right tools and software but lower hourly labor rates than dealers.
2. Stick to the Maintenance Schedule
- Do not skip or delay oil changes and major services.
- Fix early warning signs (noises, leaks, warning lights) before they damage more expensive parts.
- Use the correct oil and fluids; the wrong stuff can create huge repair bills later.
3. Consider an Extended Warranty (If the Terms Are Fair)
- Because the 10-year chance of a major repair is around 44%, some owners like the peace of mind of extended cover.
- Read the fine print; not all plans are worth the cost.
4. Choose the Right Spec
- Simpler wheels and tyre sizes are cheaper to replace.
- Avoid unnecessary air suspension or highly complex options if you worry about long-term bills.
Simple Verdict: Is the GLE 350 High Maintenance?
Putting it all together:
- Yes, the Mercedes GLE 350 is high maintenance compared with normal brands.
- Within the luxury mid-size SUV class, it is roughly average for reliability and a bit above average for cost.
If you want:
- Low running costs and simple ownership → something like a Toyota Highlander or Honda Pilot will be happier on your wallet.
- Luxury, comfort and the Mercedes badge and you are ready to budget at least $1,000+ per year on average once it ages → the GLE 350 can still be a very nice SUV to live with.
