What to look out for

The checks worth doing on a Mercedes-Benz GLE before you hand over any money. Every documented fault is listed below, each with its own page.

  • Costly issue

    Inspect both front air spring bladder sleeves for surface cracking and separation at upper and lower bead seats.

    See why

    AIRMATIC front air spring bladder failure

    The GLE V167 AIRMATIC system is standard-fit on most variants sold in NZ and AU. The front air spring bladder is a convoluted rubber sleeve operating in a high-heat, high-movement environment. Bladder cracking at the folded convolution zone causes slow air leaks that manifest as overnight corner sag. The GLE's greater kerb weight (2,100-2,400 kg) loads the bladders more heavily than lighter crossovers, accelerating fatigue life consumption. The AIRMATIC compressor is shared front and rear; persistent front bladder leaks overheat the compressor motor leading to secondary compressor failure. E-Active Body Control (E-ABC) variants on GLE 53 and GLE 450 use a more complex hydraulic-electric system but the front spring element still uses an air spring as the primary pressure vessel.

    What you would notice

    • Front corner sag visible after overnight park, typically one side lower than the other
    • AIRMATIC or ABC fault lamp on cluster
    • Compressor running audibly for long periods at startup
    • Rough, jittery ride when system enters safe mode
    • Air hissing sound from front wheel arch area

    Typically $1,600–$3,800 to put right.

  • Costly issue

    Start the car a few times and watch for any 48V/electrical warning; let stop-start cycle and feel for rough restarts.

    See why

    48V mild-hybrid (ISG) and MBUX faults (V167)

    The current GLE (V167) uses 48-volt EQ Boost mild-hybrid petrol and diesel engines. The 48V battery, integrated starter-generator and DC/DC converter are known trouble spots that trigger a '48V onboard electrical system' warning and can leave the car unable to start; some cases are software or a separate 48V ground-cable recall, others need a costly ISG or battery. The MBUX widescreen can also freeze or reboot. Verify no electrical warnings and that updates/recalls are done.

    What you would notice

    • '48V onboard electrical system' warning
    • Car won't start / long crank
    • Rough auto-restart at lights
    • MBUX screen freezes or reboots

    Typically $800–$6,000 to put right.

  • Costly issue

    Press the footwell and boot carpets for damp and sniff for a musty smell.

    See why

    Water intrusion recall - wet interior and electrical faults (V167)

    Early V167 GLE (and related GLS) SUVs were recalled because water can get into the vehicle and reach electrical components, potentially causing malfunctions. Combined with the usual blocked sunroof/scuttle drains on a big SUV, this shows as damp carpets, a musty smell, fogged glass or intermittent electrical gremlins. The recall work is free at a Mercedes dealer, so confirm it has been done and that the interior is dry.

    What you would notice

    • Damp carpets or musty smell inside
    • Fogged windows slow to clear
    • Intermittent electrical faults or warnings
    • Water in footwells or under floor trim

    Typically $0–$1,500 to put right.

01M256 48V ISG belt-alternator-starter failure

Use XENTRY to interrogate 48V EQ Boost control module for ISG and battery fault codes.hybrid2019–2025Electrical
OccasionalElectrical $4,500–$9,500 to fix

Can't confirm for this car

The M256 3.0T inline-six uses a 48-volt Integrated Starter-Generator (ISG) mounted on the front of the engine driven by a dedicated belt, replacing the conventional alternator and starter motor. The ISG enables stop-start, mild regenerative braking, and electric boost. Early production units suffer from ISG rotor bearing wear and internal winding failures, compounded by heat exposure from the adjacent engine. Failure modes include loss of stop-start function, 48V system fault warnings, battery charge faults, and in progressive cases complete 48V network shutdown causing loss of belt-driven ancillaries. The 48V lithium-ion battery (EQ Boost battery, behind the rear seat) can also fail independently, requiring a separate diagnosis pathway.

Symptoms to notice

  • EQ Boost or 48V system warning light on instrument cluster
  • Stop-start system permanently disabled with no driver option to restore it
  • Increased fuel consumption from loss of mild hybrid assist
  • 12V charging warning if 48V-to-12V DC/DC converter is also affected
  • Belt squeal or tensioner noise from ISG belt drive

What to check

  1. Use XENTRY to interrogate 48V EQ Boost control module for ISG and battery fault codes.
  2. Check 48V battery state of health and cell balance.
  3. Inspect ISG drive belt for wear and glazing.
  4. Verify 48V bus voltage under light load.
  5. Check for coolant leaks near ISG (water-cooled units).
  6. Review workshop history for any 48V network faults.

Where to look: ISG unit: front of M256 engine, belt-driven on transmission-side (longitudinal installation). 48V EQ Boost battery: behind rear seat base or under load floor depending on variant.

Parts involved: Alternator, Starter motor.

Ask the seller

  • “Has the 48V EQ Boost or ISG system ever triggered a warning or been replaced under warranty?”
  • “Is the stop-start system currently fully operational?”
  • “Has any 48V battery or high-voltage system work been carried out?”
  • “What is remaining factory or extended warranty coverage on the 48V drivetrain components?”

01Airmatic air suspension leaks and compressor failure (W164/W166)

Ideally view the car after it has stood overnight - it should sit level.2005–2019Suspension
CommonSuspension $1,200–$4,000 to fix

Does not apply

ML/GLE models with the optional Airmatic air suspension develop leaking air struts and eventually a failed compressor. A corner that sags after standing overnight, a slow rise on start-up, or an 'Airmatic - Visit Workshop' message are the signs. Struts and the compressor are expensive on a big SUV, so a neglected Airmatic car can cost thousands to put right; steel-sprung cars avoid this.

Symptoms to notice

  • A corner sagging after standing overnight
  • Slow to rise / uneven ride height on start-up
  • 'Airmatic - Visit Workshop' message
  • Compressor running constantly or failing to run

What to check

Ideally view the car after it has stood overnight - it should sit level. On start-up it should raise promptly and hold. Listen for the compressor labouring, and check for any suspension warning. A low corner means budget for struts.

Where to look: Air struts at each corner and the compressor (front of the vehicle)

Parts involved: Air suspension strut.

Ask the seller

  • “Does it sit level after standing overnight?”
  • “Have any air struts or the compressor been replaced?”
