Common Mercedes-Benz GLE350 Problems by Generation
Even a finely engineered SUV like the GLE350 can develop issues—especially in Florida’s hot, humid climate. Below is a breakdown of the most common problems seen in both the W166 (2016–2019) and V167 (2020–Present) models.
🧰 2016–2019 GLE350 (W166 Chassis)
This generation featured the M274 2.0L turbocharged I4 or the V6 (GLE350 4MATIC) paired with the 7-speed automatic (7G-TRONIC Plus). Known for its smooth ride, it also introduced early versions of Mercedes’ driver-assist systems.
Frequent Issues:
- Timing Chain Tensioner Wear: The M274 engine can experience timing chain slack or rattle, especially with irregular oil changes.
- Air Suspension Leaks (AIRMATIC models): Rear airbags often fail first, causing a sagging rear or lean to one side.
- Crankcase Vent Valve Failure: Leads to poor idle, check engine lights, and vacuum leaks.
- Oil Leaks at Camshaft Solenoid Seals: Often mistaken for more serious leaks.
- Sunroof Drain Clogging: Florida rain can overwhelm clogged drains and flood the interior.
- Transmission Fluid Leaks: Especially near the conductor plate or electrical connector.
- NOx Sensor Failure (Emissions): Causes check engine lights and poor fuel efficiency.
🧰 2020–Present GLE350 (V167 Chassis)
This generation introduced more advanced M264 turbo 4-cylinder engines, a new 9-speed automatic (9G-TRONIC), and the latest MBUX infotainment system.
Frequent Issues:
- MBUX Freezing or Rebooting: The new touchscreen infotainment is powerful but buggy. Software updates often required.
- 48V Mild Hybrid System Faults: Includes EQ Boost starter-generator problems, particularly if battery voltage is unstable.
- AIRMATIC Compressor Failure: Especially on 4MATIC models with heavier usage or towing.
- Premature Brake Pad Wear: Aggressive electronic braking assistance leads to faster wear in city driving.
- Rear Axle Thrust Arm Bushing Cracks: Results in clunking or loose rear-end feel.
- Active Parking Assist Errors: Radar sensor misalignment or calibration issues.
Warning Signs That Mean It’s Time to Call Potter’s Imports
- 🚨 Check engine light with rough idle or hesitation
- 💨 Whistling turbo sounds or hissing from engine bay
- 🚘 Vehicle sagging after overnight parking
- 🧊 Weak or non-functioning A/C
- 🧯 Burning oil or transmission fluid smells after driving
- 💡 Dashboard systems flickering or not responding

Frequently Asked Questions – Mercedes-Benz GLE350 Repair
Is the Mercedes GLE350 reliable long term?
Yes, particularly the V6 GLE350 models from 2016–2019. The M264 turbo engines (2020+) are efficient but benefit from strict oil change schedules and careful turbo maintenance.
How often should I replace spark plugs on the GLE350?
Every 50,000 miles for the M274 and M264 turbo engines. Worn plugs lead to poor fuel economy and misfires.
What does it mean if my GLE350 sags overnight?
It likely indicates a leaking AIRMATIC air strut or failing compressor. Letting it persist can wear out other suspension components.
Can Potter’s Imports work on my GLE350 hybrid system?
Yes. We service mild hybrid systems, perform battery tests, and can diagnose EQ Boost-related faults.
Is it worth fixing an older GLE350 or trading it in?
If the vehicle has been maintained well, it often makes more sense to repair. We help prioritize high-value repairs to extend ownership without overspending.
Why is my MBUX screen flickering or freezing?
Software glitches, voltage dips, or internal display faults are common causes. We can reflash MBUX and diagnose hardware faults using STAR.
