Mercedes GLE Problems: What to Know Before Buying
The Mercedes-Benz GLE is a mid-size luxury SUV offering a premium driving experience, advanced tech features, and powerful engine options. Available in SUV and coupe forms, the GLE lineup includes models like the GLE 300d, GLE 350, GLE 450, GLE 580, and AMG GLE 53 and 63 variants. While the GLE is a strong performer in its class, it is not without its issues. If you’re considering a new or used GLE — especially from the W166 (2015–2019) or W167 (2020–present) generations — here are the most common Mercedes GLE problems to be aware of.
1. AIRMATIC Suspension Faults
GLE models equipped with Mercedes’ AIRMATIC air suspension are known for their comfort, but the system can fail over time.
Common problems:
- Uneven ride height
- Suspension warning lights
- Sagging after parking
- Failing air compressor or leaking air struts
Inspect the suspension system carefully, and listen for hissing sounds or unusual bounce while driving.
2. Electrical and Sensor Malfunctions
As with many modern vehicles, the GLE is packed with electronics that can occasionally misbehave.
Frequent complaints include:
- Blind spot or lane assist errors
- Power tailgate malfunction
- Warning lights without clear cause
- Battery drain from control modules
Ensure software is up to date and that a diagnostic scan shows no stored error codes.
3. Transmission Hesitation
The GLE’s 9-speed automatic transmission is generally smooth but can experience hesitation or harsh shifts.
Signs of trouble:
- Delay when accelerating
- Jerky gear changes in stop-and-go traffic
- Warning messages or fault codes
Check if the vehicle has had transmission software updates or adaptive reset procedures.
4. DPF and AdBlue System Issues (Diesel Models)
Diesel-powered GLEs, such as the GLE 300d or GLE 400d, can develop problems related to emissions systems if mostly driven short distances.
Symptoms include:
- DPF warning light
- Limp mode or reduced power
- AdBlue refill or system error messages
- Poor fuel economy
Long highway trips help regenerate the DPF and keep the system healthy.
5. Cabin Rattles and Interior Trim Noises
While the GLE features high-quality materials, some models — particularly early W167 builds — have interior rattles or creaks.
Examples:
- Noises from dashboard or doors
- Third-row seat squeaks (if equipped)
- Loose trim on center console
These issues are minor but may be noticeable over rough roads.
6. MBUX Infotainment Glitches
The latest GLE models come with the MBUX infotainment system, which is user-friendly but not immune to bugs.
Known problems:
- Frozen screens or lag
- Bluetooth connection problems
- Navigation or voice assistant errors
Most glitches can be fixed through software updates provided by a dealer.
Final Thoughts: Is the Mercedes GLE Reliable?
Yes. The GLE is a capable, luxurious SUV when properly maintained. Most of the common issues are related to software, sensors, or routine maintenance — not major mechanical faults.
Before buying:
- Check for full service and recall history
- Test drive on varied road surfaces
- Inspect infotainment and driver-assistance systems
- Get a professional pre-purchase inspection
