The 2019 Mercedes-Benz GLE has 15 known issues documented across 5,400+ owner reports. 5 issues are rated critical: Air Suspension Compressor Failure and Electric Power Steering (EPS) Sudden Loss of Assist - "Power Steering Malfunction, See Operator's Manual" and OM651 Diesel Turbo Bearing Collapse and EGR Cooler Coolant Leak and M278 4.7L Twin-Turbo V8 (GLE 550) Timing Chain Tensioner / Camshaft Adjuster Cold-Start Rattle and Diesel AdBlue / SCR NOx Sensor Fault Triggering Restart Countdown and No-Start. Prospective buyers should inspect for these issues and factor potential repair costs into their purchase decision. Regular maintenance following the manufacturer's schedule helps prevent many common problems.
Repair costs for known Mercedes-Benz GLE issues range from $0 to $7,000, depending on the specific problem and whether you choose DIY or professional repair. The most critical issue, Air Suspension Compressor Failure, typically costs $600-$2,500 to repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
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. Repairs typically run $600-$2,500. Severity: high.
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 ve… Repairs typically run $400-$5,000. Severity: high.
The W166 GLE 250d and GLE 350d (2015-2019, OM651 2.1L twin-turbo / OM642-related diesels) have a documented pattern of turbocharger bearing collapse and EGR cooler failure, typically appearing between roughly 75,000 and 95,000 miles. Frequent short trips and DPF regeneration cycl… Repairs typically run $1,500-$6,000. Severity: high.
The M278 4.7L biturbo V8 used in the GLE 550 4MATIC (W166/C292) has a complex timing drive with one primary chain and two secondary chains, each with its own tensioner. On early engines the secondary chain tensioners lose oil pressure during shutdown because they lack anti-drainb… Repairs typically run $1,800-$6,500. Severity: high.
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… Repairs typically run $400-$1,200. Severity: high.
The diesel particulate filter (DPF) clogs prematurely, especially on vehicles used primarily for short trips. Failed regeneration cycles cause reduced power, increased fuel consumption, and eventually limp mode. Repairs typically run $300-$4,000. Severity: medium.
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 w… Repairs typically run $2,000-$7,000. Severity: medium.
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. Repairs typically run $200-$800. Severity: medium.
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, inte… Repairs typically run $300-$1,300. Severity: medium.
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… Repairs typically run $150-$450. Severity: medium.
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 st… Repairs typically run $400-$1,000. Severity: medium.
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… Repairs typically run $150-$700. Severity: medium.
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 flo… Repairs typically run $400-$1,200. Severity: medium.
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). Repairs typically run $300-$2,500. Severity: medium.
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. Repairs typically run $0-$2,500. Severity: low.
