On the 2020-2025 Mercedes-Benz GLE, gLE models equipped with the EQ Boost 48-volt mild-hybrid system (GLE 350, GLE 450, GLE 450d, GLE 580 and AMG variants on the W167 platform) commonly trigger a '48V Battery Malfunction' or 'Hybrid System Error' warning. The integrated starter-generator (ISG) and 48V lithium-ion battery, along with the DC/DC converter, are known weak points. Owners report sudden loss of drive power on the motorway, disabled stop/start, weak acceleration and repeated stalling, sometimes resolving only after the car is powered down for 10-15 minutes. A March 2022 Mercedes TSB acknowledged that the battery self-test can disconnect the 48V battery due to software, hardware, cooling or false-positive faults. Many owners report multiple unsuccessful dealer visits and weeks of downtime, with the fault often persisting under warranty.
Common Symptoms
48V Battery Malfunction warning
Hybrid System Error message
sudden loss of power while driving
weak acceleration
stop/start disabled
engine stalls and restarts after waiting
noisy auxiliary fan
How to Fix
Have the dealer perform Xentry diagnostics and apply the latest 48V/ISG control-unit software update first, as many cases are false-positive disconnects fixed in software. Persistent faults require replacement of the 48V battery, the integrated starter-generator (ISG/alternator unit), or the DC/DC converter. Check the 48V ground cable connection (subject of a separate recall) before condemning the battery. Repairs are typically covered under the powertrain/hybrid warranty; out of warranty an ISG replacement is a major job.
On the 2016-2024 Mercedes-Benz GLE, the GLE uses a small secondary AGM 'auxiliary' battery (separate from the main starter battery and the 48V mild-hybrid battery) that stabilizes voltage for the electrical/stop-start system. It is a known wear item that typically dies at 4-6 years, throwing a persistent 'Auxiliary battery malfunction – Visit workshop' message. On W166 (2016-2019) it lives under the rear seat / luggage area; on W167 it is in the engine bay area. Symptoms include the dash warning, flaky start-stop, random electrical gremlins, and occasionally a no-start. This is one of the most-searched GLE electrical complaints.
Replace the auxiliary battery – it is a straightforward ~20-minute DIY. Genuine Mercedes OEM auxiliary battery is 12V 12Ah 200A, part number A0009829608 (000 982 96 08); OE-equivalent AGM units are sold as 'AUX14' / EK131 cross-references. After replacement no coding is required on most years, though a battery reset via diagnostic scanner clears residual faults. Genuine part runs ~$120-180; independent shop install ~$150-450 total.

On the 2016-2025 Mercedes-Benz GLE, the GLE's full-LED / MULTIBEAM headlights are ventilated for heat, but when the factory seal or housing gasket fails, humid air enters and heavy condensation forms — large droplets and standing water at the bottom of the housing (not the light misting Mercedes considers normal). Because the LED modules and ballast/control electronics are not individually serviceable, trapped moisture corrodes them and causes flicker, partial-out DRL/turn segments, or complete headlight failure, forcing a very expensive full assembly replacement.
Common Symptoms
Water droplets or pooling inside headlight lens
Persistent condensation that does not clear
Flickering LED or dead DRL/turn-signal segments
Complete headlight failure
Corrosion visible inside housing
How to Fix
Distinguish normal light fog (clears with use) from a failed seal (droplets/pooling/tide-marks). For early cases Mercedes has a service bulletin using an absorbent desiccant pad and resealing the housing. Once electronics/LED modules fail, the full headlight assembly must be replaced — MULTIBEAM units are among the priciest body-electrical parts on the car. Document moisture and pursue warranty/goodwill where possible. Reseal ~$150-400; full LED/MULTIBEAM assembly $1,200-2,500+ per side.
On the 2016-2024 Mercedes-Benz GLE, gLE plug-in hybrids (W166 550e; W167 350de diesel-PHEV and 450e) frequently show AC-charging faults: charging starts then stops and restarts, a red plug icon, or the car refuses to accept a charge at home/wallbox. Documented triggers include the vehicle halting when the voltage difference between supply phases exceeds ~19V, a weak 12V battery (below ~12.4V the car can't initiate HV charging), a stuck/corroded charge-port latch, or software glitches throwing false charging warnings.
Common Symptoms
Charging starts then stops and restarts repeatedly
Red plug icon / charging fault message
Car will not accept a home charge
Charge port door stuck or won't latch
False charging warnings that clear on reset
How to Fix
Start with a hard reset: lock the car, wait ~15 minutes, unlock and re-plug. Verify the 12V battery health (must be healthy to command HV charging) and check the charge-port door/latch for debris or corrosion. Test on a known-good EVSE/wallbox to rule out supply phase-imbalance. If a red-plug fault persists, a dealer XENTRY scan of the onboard charger/HV system and a software update are usually needed. DIY checks are free; dealer diagnosis/charge-port or software work $200-1,500.
On the 2016-2023 Mercedes-Benz GLE, the infotainment system (COMAND on 2016-2019, MBUX on 2020+) freezes or reboots. The COMAND hard drive fails over time while the MBUX system is susceptible to software glitches with connected phones.
Common Symptoms
Infotainment screen freezes or goes black
Backup camera unavailable
How to Fix
For COMAND: update firmware and check the internal hard drive health. For MBUX: perform a reboot (hold volume + track-forward 10 seconds) and update software. Disconnect phone to test if the issue is CarPlay/Android Auto related.
Owner tips & cautions
TipDelete and re-pair your phone Bluetooth connection. Corrupted phone pairing profiles cause the majority of MBUX freeze events.

On the 2016-2023 Mercedes-Benz GLE, the AIRMATIC compressor fails prematurely on the GLE, typically after one or more air springs develop slow leaks. The heavy SUV puts more stress on the compressor than sedan applications, accelerating wear.
Common Symptoms
Vehicle drops to lowest position overnight
Compressor runs for extended periods
How to Fix
Replace the compressor and relay. Leak-test all four air springs and replace any that are leaking. The compressor runs $400-800 for aftermarket (Arnott) or $1,200+ OEM.

On the 2016-2025 Mercedes-Benz GLE, both W166 (2016-2019) and W167 (2020+) GLEs wear out the front lower control arm bushings. The lower arm carries multiple rubber bushings (including a rear 'lollipop' mount to the body) that tear with age, producing a clunk/knock over bumps, a wandering or vague feeling in the steering, and uneven front tire wear. It is one of the most common GLE front-end noise complaints and shows up regardless of whether the car has AIRMATIC or steel springs.
Common Symptoms
Clunk / knock from front over bumps
Wandering or vague steering
Uneven/inner front tire wear
Vibration or looseness at speed
Noise when turning into driveways
How to Fix
Lift and inspect the bushings for tears and wiggle the wheel to reproduce the noise. Either press in a new OE-quality bushing set or replace the complete lower control arm assembly — W167 genuine arms are left A1673300700 and right A1673300800 (167-330-07-00 / 167-330-08-00); W166 uses the 166-series arms/bushings. An alignment is required afterward. Bushing set is cheaper but labor-intensive; full arms run $150-300 each. Job total typically $400-1,000 with alignment.

On the 2020-2023 Mercedes-Benz GLE M264 2.0L I4 Turbo, the base GLE 350's M264 2.0L turbo four-cylinder can develop a worn/weak timing chain tensioner and chain stretch, producing a rattle (often on cold start or under load) from the front of the engine. If ignored, chain stretch can throw camshaft/crankshaft correlation codes and, in the worst case, cause valve-to-piston contact. Metal shavings in the oil or a check-engine light for timing correlation are red flags.
Common Symptoms
Rattle/chatter from front of engine on cold start
Rattle under acceleration
Check-engine light for timing correlation
Metal shavings at oil change
Rough running in severe cases
How to Fix
Diagnose with cam/crank correlation data and a listen test at cold start. Replace the timing chain tensioner (genuine Mercedes tensioner part number A2700521400 / 270-052-14-00, fits 2016-2023 M264/M270/M274) and, if the chain is stretched, do the full timing chain kit (Mercedes kit 0009935002 covers chain + guides). Use only OE-spec 0W-20/5W-30 (229.71) oil at correct intervals to prolong tensioner life. RepairPal estimates GLE350 tensioner replacement at ~$1,591-$2,121; full chain job runs higher.
On the 2016-2025 Mercedes-Benz GLE, the GLE uses fluid-filled (hydraulic) engine and transmission mounts to isolate NVH. These are a known consumable that ruptures and leaks its damping fluid, often well before 60-70k miles. A collapsed mount transmits noticeable vibration through the steering wheel, seats, and floor at idle/in-gear, plus a thump or clunk when shifting or accelerating. A dark oily stain under the mount confirms rupture. Ignoring it can chafe hoses/belts and accelerate driveline wear.
Common Symptoms
Vibration through steering wheel/seat at idle or in gear
Thump/clunk when shifting into Drive or Reverse
Shudder on acceleration
Oily fluid stain under engine mount
Vibration worsens when A/C is on
How to Fix
Inspect mounts on a lift for fluid leakage and excess movement; replace in pairs. On W167 the electronic (sensor-equipped) engine mounts are left A1672407200 and right A1672407300 (167-240-72-00 / 167-240-73-00); W166 (2016-2019) GLE350/400 use the non-sensor 166-series mounts, and a matching transmission mount is often replaced at the same time. Parts $150-350 each; independent labor brings a pair to roughly $400-1,200 total.

On the 2016-2024 Mercedes-Benz GLE, on diesel GLEs, the SCR/AdBlue emissions system enforces compliance with a start countdown: when it detects a fault it warns 'You can restart the engine X more times,' and once the counter expires the car will not start until the fault is fixed and the counter is reset. The most common root cause is a failed upstream or downstream NOx sensor giving out-of-range readings; other causes are AdBlue crystallization, a blocked dosing valve, or low-quality fluid. Topping up AdBlue does NOT clear the countdown.
Common Symptoms
'Start engine X more times' AdBlue countdown warning
'Check AdBlue / see owner's manual' message
No-start after countdown expires
Check-engine light with NOx/SCR codes
Reduced power / limp mode
How to Fix
Scan with XENTRY/compatible tool and read live NOx sensor, dosing, and SCR temperature data to pinpoint the failed component. Replace the faulty NOx sensor — OM642/OM651-era downstream sensor is part number 0009058611 (also 000905350364 for the pre-SCR sensor); newer OM654/OM656 diesels use NOx sensor 000-905-48-07 (0009054807). Then have the SCR no-start counter reset (requires dealer/specialist software; it will not clear on its own). NOx sensor part ~$150-350; diagnosis + sensor + reset typically $400-1,200.
On the 2016-2022 Mercedes-Benz GLE, gLE owners (W166 and W167) report sudden loss of electric power steering assist, sometimes immediately after engine start and sometimes intermittently while driving, accompanied by the red dashboard message "Power Steering Malfunction - See Operator's Manual." Steering becomes very heavy, especially at low/parking speeds. Because EPS relies on stable voltage, CAN/FlexRay communication, and accurate sensor data, causes are almost always electrical: EPS control-module/torque-sensor faults, a corroded/loose steering-rack ground or harness connection, a blown power-steering pre-fuse, or a weak 12V battery dropping voltage to the EPS motor. NHTSA recall 16V899000 covers 2016-2017 GLE (350/400/300d/550e/43/63, etc.) where an insufficiently sealed EPS connector lets water into the control unit and deactivates assist, and TSB MC-10231025 addresses a no-assist-after-start software fault of the N68 EPS control unit on later models. This is an electronic EPS-rack fault, separate from mechanical front control-arm bushing wear.
Common Symptoms
"Power Steering Malfunction, See Operator's Manual" red warning message
Sudden heavy / hard-to-turn steering, worst at parking speeds
Intermittent loss and return of power assist after restart
Steering warning light illuminated
Occasional correlation with low/weak 12V battery
How to Fix
Diagnose with XENTRY for C15xx EPS codes; first rule out and correct low battery voltage, a blown power-steering pre-fuse, and corroded/loose steering-rack ground and power connectors (common fixable causes). Check VIN for recall 16V899000 (connector reseal + rack inspection/replacement) and applicable EPS software TSBs. If the fault is internal, the EPS control unit / torque sensor or the complete electric steering rack is replaced (or reconditioned) and coded to the vehicle.
On the 2016-2022 Mercedes-Benz GLE, the 4MATIC transfer case on 2016+ GLE develops two related failures over time: stretched drive chains (which cause a metallic rattle or grinding noise from under the vehicle, most audible at low speeds or under light acceleration) and worn output-shaft bearings (which produce a whine that changes pitch with vehicle speed). Severe wear can cause torque-distribution problems and, if ignored, eventual transfer case failure requiring full unit replacement.
Common Symptoms
4WD/4MATIC warning light on dashboard
Grinding noise from transfer case area
How to Fix
Diagnose with a stethoscope or chassis ear to confirm the noise originates from the transfer case (rather than the rear differential or driveshaft carrier bearing). Drain and inspect the transfer case fluid: metal flakes confirm internal wear. Early chain stretch can sometimes be addressed with a fluid change and a chain replacement; advanced bearing wear typically requires full transfer case replacement. OEM Mercedes transfer cases run $3,000-$6,000 plus 4-8 hours labor; rebuilt units from specialty shops are 30-50% cheaper.
Owner tips & cautions
TipThe actuator motor is a bolt-on replacement. If you are handy, this is a 2-hour DIY job. The motor itself is $200-400 — shops charge $800+ for labor.

On the 2016-2022 Mercedes-Benz GLE, the rear differential develops a leak at the pinion seal or cover gasket. Fluid loss causes differential whine and, if left unaddressed, can lead to bearing and gear damage from insufficient lubrication.
Common Symptoms
Oil drip from rear differential area
Whining noise from rear at highway speed
How to Fix
Replace the leaking pinion seal or differential cover gasket. Refill with the correct GL-5 75W-85 gear oil. Inspect the differential gears and bearings for damage if the fluid level was critically low.
Owner tips & cautions
TipCheck the rear differential fluid level at every oil change. A slow leak may not leave visible drips but can cause damage over time.

On the 2020-2024 Mercedes-Benz GLE, on the W167 GLE (2020-2024), the front radar sensor behind the grille that feeds Distronic adaptive cruise control, Active Brake Assist and PRE-SAFE frequently faults, throwing 'Pre-Safe Functions Currently Limited' and disabling those safety systems. Code P2583 indicates the front radar is offline. Common causes are a dirty or snow/ice-blocked sensor, sensor misalignment after minor front-end impacts, and wiring/connector corrosion in the harness (W167 harness part A1675401443) near the right front bumper; a fault in the 48V system can also cascade into ADAS errors. The car remains drivable but loses automatic emergency braking and adaptive cruise.
Common Symptoms
Pre-Safe Functions Currently Limited warning
Distronic / adaptive cruise unavailable
Active Brake Assist inoperative
intermittent ADAS warnings
radar sensor dirty message
How to Fix
Start by cleaning the radar emblem/sensor area in the grille and clearing snow, ice, mud or badge film, which resolves many cases. If the fault persists, scan for P2583, inspect the radar harness connector near the right front bumper for corrosion or broken pins and repair as needed, then have the radar recalibrated (or replaced if failed) with Xentry. Rule out 48V-system faults that can trigger ADAS errors.
On the 2020-2024 Mercedes-Benz GLE, gLE 350 and GLE 450 models (2020+, 9G-Tronic 9-speed automatic) develop harsh low-gear shifts, clunking, and delayed engagement when selecting Drive or Reverse as the transmission ages. The most common root cause is degradation of the valve-body solenoids and conductor plate, aggravated by Mercedes marketing the ATF as 'lifetime' fill when real-world driving needs service far sooner. Contaminated or degraded fluid accelerates solenoid wear, producing erratic shift quality and occasional limp mode.
Common Symptoms
harsh or clunky low-gear shifts
delayed engagement into Drive or Reverse
shift flare or hesitation
occasional limp mode
transmission warning light
How to Fix
Service the transmission fluid and filter on a real interval (roughly every 40,000-60,000 miles) rather than treating it as lifetime fill, using the correct Mercedes-spec ATF. If harsh shifting or delayed engagement persists after a fluid service, have the valve body / conductor plate and solenoids inspected and replaced, followed by an adaptation reset. Address any stored transmission DTCs.

On the 2020-2025 Mercedes-Benz GLE M256 3.0L turbocharged I6 (EQ Boost), the 3.0L M256 inline-six (GLE 450, AMG GLE 53 on the W167) is prone to oil leaks from the oil filter housing/adapter assembly, which integrates the engine oil cooler with coolant passages, making leaks both oil and coolant related. The M256 also relies on an electric coolant pump and an auxiliary electric water pump that can fail, producing erratic cooling behavior and overheating warnings. Because oil and coolant circuits share the adapter, an internal cooler leak can let coolant migrate into the oil and quickly damage the engine. Owners also report cold-start timing-chain rattle and oil consumption past ~60k miles on this engine.
Common Symptoms
oil spots under engine
coolant loss
low coolant / overheating warning
erratic temperature gauge
oil and coolant mixing
cold-start timing chain rattle
oil consumption between services
How to Fix
Pressure-test the cooling system and inspect the oil filter housing/adapter and integrated oil cooler for seepage; replace the housing gaskets/seals or the complete adapter as needed and refresh coolant. Test the electric coolant pump(s) and replace failing units. Investigate any coolant-in-oil immediately to prevent bearing damage. Monitor oil level between services given the engine's oil-consumption tendency.

On the 2016-2025 Mercedes-Benz GLE, the large panoramic roof has four corner drain tubes that route rainwater down the pillars. Over time the tubes clog with dirt/pollen/debris and the perimeter rubber seals degrade, so water backs up and drips onto the headliner, A-pillars, and front footwells, or pools and causes musty smell/mold. Owners also report a persistent creak/rattle from the roof over bumps caused by loose drip-rail cover clips and dry sunroof tracks. This is distinct from the A/C drain-hose footwell recall – the source here is the roof drains/seals.
Common Symptoms
Water dripping from headliner or A-pillar in rain / car wash
Damp front footwells or carpet
Musty / moldy smell
Creaking or rattling from roof over bumps
Water stains on headliner
How to Fix
Have the sunroof drain tubes flushed with low-pressure water or compressed air at each corner (a common wet-vac/blow-out service); replace degraded perimeter seals if leaking persists. For the rattle, re-seat or replace the drip-rail cover clips (often warranty/goodwill with a foam or double-sided-tape shim) and lubricate the sunroof guide rails with Mercedes-approved sunroof grease. Preventive drain cleaning every 1-2 years avoids interior water damage. Drain cleaning ~$100-200; seal/track service higher if headliner or trim is affected.

On the 2016-2023 Mercedes-Benz GLE, the GLE power tailgate uses a motorized spindle drive on the passenger side plus a gas strut on the driver side, managed by a dedicated Tailgate/rear-compartment control module. A very common complaint is the gate opening a few inches then stopping or immediately re-closing, intermittent operation, or the gate not moving at all. Causes range from a weak battery/blown fuse (F152 30A, F154 40A) to a failed spindle-drive motor to a control-module internal error (fault code B224E49).
Common Symptoms
Tailgate opens a few inches then stops or re-closes
Power liftgate completely dead
Intermittent open/close operation
Gate reverses mid-cycle
Buzzing from spindle drive with no movement
How to Fix
First check fuses F152/F154 and battery health, then perform the manual liftgate reset/re-initialization. Mercedes has a TSB for module fault B224E49 whose fix is a dealer software update and re-coding (no parts). If a spindle drive is mechanically failed, replace the passenger-side actuator; the rear-liftgate control module (genuine W166 part A1669008512 / 166-900-85-12) is the unit re-coded or replaced for control faults. Reset/recode is low cost; spindle-drive or module replacement $300-1,300.
