Mercedes-Benz GLE V167
Weaknesses, engine ratings and buying advice
The V167 is the current GLE generation — on sale since 2019, completely redesigned on the MHA platform. Larger, more comfortable, and technically far more advanced than the W166 predecessor. First with E-Active Body Control (active air suspension with 48V hydraulics) and comprehensive electrification.
The diesel lineup is strong: the OM654 2.0L (180–235 kW) covers the GLE 300d and GLE 350de (plug-in). The OM656 inline-six 2.9L (200–250 kW) in GLE 350d and GLE 400d is the long-distance reference — an incredibly quiet and efficient engine. For diesel highway driving, take the OM656.
Petrols include the M264 2.0L at 188 kW in the GLE 350 as entry, the M256 inline-six at 270–320 kW in GLE 450 and AMG GLE 53, and the M177 V8 BiTurbo (420–450 kW) in AMG GLE 63 variants. The M256 with 48V support is the technical highlight: electric auxiliary compressor eliminates turbo lag, ISG provides boost and recuperation.
Since the V167 is still relatively young, long-term data is limited. Known issues: MBUX software (improved through updates), E-Active Body Control noise in cold weather, and the 9G-Tronic can seem indecisive in city traffic. Plug-in models (GLE 350de) have a large battery — have SOH checked after 4 years.
Test-drive checklist: Test E-Active Body Control (if equipped) on different surfaces — noises? Run through MBUX completely. Cold-start the diesel — the OM656 should be practically silent. AMG: test launch control once and listen for gearbox noises.
2026 market: Between $42,000 and $93,500. Wide spread depending on spec and engine. GLE 400d with OM656 is the most value-stable configuration.
Insider pick: GLE 400d (OM656, 243 kW) — the best diesel SUV of its generation, period.

Engine Overview
The Mercedes-Benz GLE V167 is available with 19 engine variants — from 116 to 612 hp.
Completely new aluminium diesel with NANOSLIDE coating and integrated particulate filter. Initially marketed as the future of diesel, but significant issues have emerged: rocker arms and camshafts wear prematurely (TSB GI05.30-P-070181); Mercedes improved the parts from engine serial number 80278367 (October 2018). Major recalls include the timing chain recall and coolant pump recall (fire risk, ~800,000 vehicles affected). Also implicated in emissions scandal via illegal thermal window defeat device (LG Stuttgart 2020). Shorten oil change intervals to max 15,000 km — extended intervals accelerate rocker arm wear.
- !! Rocker Arm and Camshaft Wear from 80,000 km
Known weak point: the narrow camshaft lobes and rocker arms in the OM654 wear prematurely due to inadequate lubrication. Mercedes issued TSBs.
Symptoms: Ticking or knocking from engine bay, misfires, rough running, engine warning light - !! Electric Coolant Pump Leaking — Recall
Over 800,000 Mercedes diesel vehicles with OM654/OM656 were recalled due to a leaking electric coolant pump. Coolant loss can lead to overheating.
Symptoms: Coolant loss, overheating warning, coolant warning light, engine temperature rises - !! NOx Sensor Defective — AdBlue Fault and Start Inhibit from 90,000 km
NOx sensors wear out from soot particles and deliver erroneous readings. Consequence: incorrect AdBlue injection, CEL illumination; if unaddressed, an engine start inhibit may follow. Both sensors can be affected.
Symptoms: CEL, AdBlue warning, fault code P20EE or P204F, message 'No start after X km', rough idle

Modern inline-six diesel with aluminium block and steel pistons — technically the highest-quality diesel in the current Mercedes line-up. The vacuum-controlled coolant pump was subject to a recall (action code 2090008) due to fire risk from coolant entering the vacuum circuit. Piezo injectors sensitive to water-contaminated or low-quality diesel (CP4 fuel pump). Camtronic actuators require regular maintenance. DPF clogging on pure city use. Regular motorway driving recommended as maintenance.
- !! Recall Coolant Pump — Fire Hazard (Action Code 2090008)
The vacuum-controlled coolant pump can develop leaks between the coolant and vacuum circuits. Coolant enters the EGR solenoid valves; an electrochemical reaction creates a fire hazard.
- !! Bosch CP4 Pump Sensitive to Fuel Quality from 120,000 km
The Bosch CP4 high-pressure pump is more sensitive to fuel contamination than its predecessors. Poor diesel quality can damage the pump and injectors.
Symptoms: Power loss, hesitation, injection system fault codes, in severe cases engine damage from metal swarf - !! Rocker Arms Prematurely Worn — Camshaft Damage from 100,000 km
Early OM656 units had overly soft roller rocker arms. From engine number 80278367 (10/07/2018) a reinforced version was fitted. Older engines develop camshaft wear and timing chain problems.
Symptoms: Clattering tick in the valvetrain, especially on cold start, increased oil consumption, CEL, rough running

Return to the inline-six after years of the M276 V6 — and the difference is immediately noticeable. Smoother, more even rev build-up, torque plateau from 1,600–4,000 rpm without any weakness. The 48V mild-hybrid system with integrated starter-generator (ISG) is not a marketing term: 16 kW of boost on pull-away fills turbo lag completely; measurable fuel saving in sail mode. When buying, check the 48V battery — failure costs 2,000–4,000 EUR, primarily affecting build years up to 2022. Electric coolant pumps can fail from 80,000 km. Change oil every 10,000 km, do not rely on Longlife — HPFP and camshaft adjusters are sensitive to old oil. Cold-start wastegate bushing rattle is by design and not a fault. Overall a very accomplished engine that holds 250,000 km without issues when maintained correctly.
- !! 48V ISG Battery Failure from 70,000 km
Frequently reported problem: 48V battery of the EQ Boost system fails and costs 2,000–4,000 EUR to replace. Design issue with earth connection in early vehicles.
Symptoms: EQ Boost deactivated, start-stop system failed, hybrid warning light, sporadic starting problems - !! Camshaft Adjuster Solenoid Leaking — Oil in Wiring Harness from 100,000 km
The known Mercedes problem of leaking camshaft solenoids also affects the M256 (same solenoid technology as M276/M270). Oil migrates by capillary action and destroys lambda sensors and the ECU.
Symptoms: Lambda sensor fault codes, MIL, rough running. Multiple electrical faults simultaneously as it progresses - !! Elevated Oil Consumption at Higher Mileage from 100,000 km
M256 shows elevated oil consumption from approx. 100,000 km, attributable to the PCV system and cylinder walls. Regular oil level checks necessary.
Symptoms: Dropping oil level, occasional bluish smoke after warm-up phase

The M177 is AMG's most widely used V8 biturbo today and is considered technically mature and long-lived. The hot-V turbocharger arrangement delivers spontaneous response with barely perceptible lag. Weaknesses are manageable: wastegate rattle in cold weather, ignition coil recall for early 2015 model years, valve cover gaskets with age. Regular oil changes with attention to oil quality deliver a very robust engine. In direct comparison with the M156 less emotional, but significantly more reliable and efficient.
- !! MCT Gearbox — Clutch Wears in City Traffic from 60,000 km
The MCT Speedshift gearbox (wet launch clutch instead of torque converter) wears the clutch significantly faster in frequent stop-and-go. Clutch replacement requires gearbox removal.
Symptoms: Judder on pull-away, clutch slip at full load, gearbox warning message, delayed engagement from standstill - !! Camshaft Adjuster Solenoid Draws Oil into Wiring Harness from 70,000 km
Identical issue to the M176/M278: the solenoid leaks, oil migrates by capillary action through the wiring harness. On AMG vehicles this is even more frequent due to higher oil temperatures.
Symptoms: Cold-start rattle, camshaft adjuster fault code, oil traces on connector, potential ECU consequential damage - !! Timing chain guide failure from 100,000 km
At higher mileage the plastic timing chain guide rails can fracture. Debris enters the oil sump and can cause secondary damage. Repair costs €4,000–8,000.
Symptoms: Tek-tek-tek noise on cold start that disappears after a few minutes. Later: extended start times, knocking from engine bay

Four-cylinder turbo with 48V belt starter-generator (BSG) — sister engine to the M254 but for longitudinally mounted applications (C/E/GLC Class). Exhaust valve seat wear is the critical issue: cylinder head replacement costs €6,000–10,000, often occurring just after warranty expiration. Electric water pump shows early failures from 50,000 km. 48V BSG inherently little proven, first failures being reported. Timing chain reliable with correct oil change rhythm. OPF clogging on frequent short trips. Oil interval max 10,000 km.
- !! Exhaust Valves Defective — Cylinder Head Damage (Serial Defect) from 70,000 km
Exhaust valve seat and guide wear leads to compression loss and severe engine misfires. Full cylinder head replacement required ($6,000–$10,000). Mercedes extended warranty covers M260 fully; M264 owners have had mixed results claiming coverage.
Symptoms: Sudden severe misfires, CEL flashing, power drop, dangerous stalling at motorway speed - !! HV Cables and E-Motor Integration Defective (PHEV) from 60,000 km
The electric motor is integrated into the 9G-Tronic. With faults in the high-voltage cables the gearbox must be removed — extremely costly repair.
Symptoms: Fault message 'Hybrid drivetrain disturbed', no electric drive possible, vehicle runs as pure combustion engine only, sometimes emergency shutdown - !! Chain Tensioner Loses Tension — Chain Rattling from 80,000 km
The hydraulic chain tensioner on the M264 can lose oil pressure after extended standstill. On cold start the timing chain rattles briefly until oil pressure builds.
Symptoms: Brief rattling on cold start (2–5 seconds), disappears after warm-up

Evolved four-cylinder turbo with direct injection and piezo injectors. Significantly less prone to timing chain problems than the M271, but not immune. Electric thermostat tends to fail early — always replace as complete OEM unit. Early DE20 LA units (2015–2016) have a piston pin manufacturing tolerance issue — short block replacement required if symptom arises. Camshaft solenoids (Y49/1, Y49/2, pre-2014) prone to leaks. Oil changes every 10,000 km with MB 229.5 recommended.
- !! High-Pressure Pump Faulty or Noisy from 120,000 km
The high-pressure fuel pump on the M274 is driven by a lobe on the intake camshaft. Wear on the drive lobe or pump follower leads to pressure drop.
Symptoms: Metallic ticking from engine area, starting problems or extended cranking, power loss, fault code P0087 - !! Camshaft Adjuster Leaks — Oil in Wiring Harness from 100,000 km
On the M274 too, the camshaft adjuster solenoids develop leaks. Oil penetrates the wiring harness by capillary action and can damage the engine ECU.
Symptoms: Fault code P0010, CEL, oil traces at camshaft connectors, lambda sensor failure, in severe cases ECU failure - !! Piston Pin Knock (2015–2016 units) from 60,000 km
Early M274 DE20 LA units (2015–2016) have a manufacturing tolerance issue with excessive piston pin clearance. Blue smoke and oil consumption up to requiring short-block replacement.
Symptoms: Metallic knocking from engine block, blue-grey exhaust smoke, increased oil consumption

4.0-litre V8 with two turbochargers in the cylinder valley — the so-called hot-inside-V arrangement keeps the exhaust paths short and virtually eliminates turbo lag. The M176 is the civilian variant of the AMG V8: same basic architecture, different mapping, not a hand-built individual unit. Water-cooled charge air coolers in the cylinder valley reduce intake charge temperature from over 140°C to near ambient. Cylinder deactivation silences four cylinders at part-load — only perceptible as minimal steering wheel vibration. Maintenance note: do not push oil change intervals, as the oil separator in the crankcase breather reacts badly to old oil and, when blocked, pushes out the valve cover gasket — extensive front-end disassembly required. Change spark plugs every 80,000 km, plan intake valve carbon cleaning after 70,000 km. When buying used, listen for wastegate rattle at part-load — addressable via Xentry. Check camshaft adjuster solenoids for oil traces at the connector.
- !! Timing Chain Stretch — M176 4.0L V8 from 120,000 km
The timing chains on the M176 V8 can stretch at high mileage. Due to the hot-inside-V design the repair is very complex as the turbochargers sit between the cylinder banks.
Symptoms: Chain rattling on cold start, camshaft fault codes, rough idle - !! Camshaft Adjuster Solenoid Draws Oil into Wiring Harness from 80,000 km
The camshaft adjuster solenoid on the M176 leaks and oil migrates by capillary action through the wiring harness to the ECU. A known Mercedes V8 issue since the M278.
Symptoms: Cold-start rattle for 1–2 seconds, camshaft adjuster fault code, oil traces on connector, in extreme cases ECU failure - !! Coolant Pump Leaking from 80,000 km
The coolant pump on the M176 can develop a leak at the seal. Coolant loss leads to engine overheating if not addressed.
Symptoms: Coolant level drops, coolant puddle under the vehicle, temperature gauge rises
